Differences in predatory pressure on terrestrial snails by birds and mammals. (7/73)

The evolution of shell polymorphism in terrestrial snails is a classic textbook example of the effect of natural selection in which avian and mammalian predation represents an important selective force on gene frequency. However, many questions about predation remain unclear, especially in the case of mammals. We collected 2000 specimens from eight terrestrial gastropod species to investigate the predation pressure exerted by birds and mice on snails. We found evidence of avian and mammalian predation in 26.5% and 36.8% of the shells. Both birds and mammals were selective with respect to snail species, size and morphs. Birds preferred the brown-lipped banded snail Cepaea nemoralis (L.) and mice preferred the burgundy snail Helix pomatia L. Mice avoided pink mid-banded C. nemoralis and preferred brown mid-banded morphs, which were neglected by birds. In contrast to mice, birds chose larger individuals. Significant differences in their predatory pressure can influence the evolution and maintenance of shell size and polymorphism of shell colouration in snails.  (+info)

In recent years, Cepaea nemoralis, the introduced European Grovesnail, has been turning up more and more.. This past summer I was asked to identify two separate records of C. nemoralis from Quesnel, BC. The population there is apparently well-established. However, in the Bulkley Valley where I live in north-central BC, Cepaea nemoralis certainly isnt common.. As far as I know, its been found at least on three occasions over three years. The first individual brought to my attention was a large adult found on a road in a rural part of Smithers in October 2008. A little later that fall, in my own vegetable garden, I found an immature snail. Its presence there was almost certainly due to the movement of plants north from by dads garden, then in Surrey. In the two years since then, Cepaea nemoralis hasnt been seen again in my garden so I can presume that this unintentional transplant failed.. The third observation on Cepaea in the Valley was in September 2010, in the village of Telkwa about 15 km ...

Increased understanding of the molecular components involved in reproduction may assist in understanding the evolutionary adaptations used by animals, including hermaphrodites, to produce offspring and retain a continuation of their lineage. In this study, we focus on the Mediterranean snail, Theba pisana, a hermaphroditic land snail that has become a highly invasive pest species within agricultural areas throughout the world. Our analysis of T. pisana CNS tissue has revealed gene transcripts encoding molluscan reproduction-associated proteins including APGWamide, gonadotropin-releasing hormone (GnRH) and an egg-laying hormone (ELH). ELH isoform 1 (ELH1) is known to be a potent reproductive peptide hormone involved in ovulation and egg-laying in some aquatic molluscs. Two other non-CNS ELH isoforms were also present in T. pisana (Tpi-ELH2 and Tpi-ELH3) within the snail dart sac and mucous glands. Bioactivity of a synthetic ELH1 on sexually mature T. pisana was confirmed through bioassay, with snails

The snails Cepaea nemoralis and C. hortensis are remarkable for an extensive and stable polymorphism involving the colour and banding of the shell. It was formerly thought that the variation in frequency of the different morphs between populations was random. Cain & Sheppard, for nemoralis and Clarke, for C. hortensis, have shown that in many English colonies visual selection by thrushes, and no doubt other predators, strongly influences the frequencies of the morphs, the more conspicuous on a given background being more heavily predated. In consequence populations tend to match their backgrounds, but remain polymorphic. In some districts of high chalk downland, this correspondence with background does not occur. The predominance of a few morphs irrespective of habitat and background characterizes areas vastly larger than that of a panmictic population. Such a constancy of morph frequencies over a large and diverse area in spite of visual selection we call an area effect. The principal district ...

Underground drilling on the Boulder vein system in the 1980s intersected sulphides along the margins of the vein, predominantly on the hangingwall. In decreasing order of abundance, sulphides consisted of disseminated pyrrhotite, pyrite, chalcopyrite and arsenopyrite. The Boulder vein system changes character downdip and along strike from a more massive quartz vein to a quartz stringer with pervasive silicification. The sulphide content also increases downdip and occurs as a silica-sulphide replacement zone. Tuffaceous sediments in the hangingwall also contain more sulphides downdip. During drilling, visible gold was noted in at least three areas of replacement and appeared to be associated with arsenopyrite. The best intersections from underground drill holes were from drill holes U-15 and U-19. The 1.4-metre interval between 23.9 and 25.3 metres from drill hole U-15 yielded 20.57 grams per tonne gold (Assessment Report 23492). The 1.6-metre interval between 14.6 and 16.2 metres from drill hole ...

Actually, it was the first Hardshell "founding fathers" who, more than Montgomery and neo-Hardshells, made spiritual birth to be totally like natural birth. They argued that there were clear stages in birth. First, there is conception, the actual implanting of the divine seed, or "regeneration," next followed by a time of hidden growth in the womb, or "conviction" of sin by the workings of the law, and then final deliverance from the womb, or salvation. In this paradigm, "regeneration" was by the "Spirit alone," apart from all means, God planting his seed, generating "life," while "conviction" represented the regenerated soul under conviction and struggling for relief, and finally the emergence of the child from the womb was represented as the time when the regenerated soul was converted. Many of the first Hardshells believed that all three stages were necessary for one to be "born again." Thus, they did not equate being "regenerated" with being "born again." They also saw themselves as ...
Question: What exact material are paintball shells generally made of? I need to write a paper for my materials class and I want to do a little research on prolonging the shelf life of a paintball. I know that a large problem is that they absorb water and swell. I propose that there could be some coating put on the paintball that would prevent this or at least delay it, giving paintballs a longer shelf life. My biggest concern is environmental impact.

On the whole, the fossil record only contains mineralised exoskeletons, since these are by far the most durable. Since most lineages with exoskeletons are thought to have started out with a non-mineralised exoskeleton which they later mineralised, this makes it difficult to comment on the very early evolution of each lineages exoskeleton. We do know that in a very short course of time just before the Cambrian period exoskeletons made of various materials - silica, calcium phosphate, calcite, aragonite, and even glued-together mineral flakes - sprang up in a range of different environments.[7] Most lineages adopted the form of calcium carbonate which was stable in the ocean at the time they first mineralissd, and did not change from this mineral morph - even when it became the less favorable.[2]. Some Precambrian (Ediacaran) organisms produced tough but non-mineralized outer shells,[3] while others, such as Cloudina, had a calcified exoskeleton,[6] but mineralized skeletons did not become common ...

My group have spent many hours in the field this week to survey the invertebrate communities in tide pools. We want to know if mobility is an important factor in allowing species to live in the high intertidal zone where they will be subject to warmer water, lower dissolved oxygen concentrations, and reduced access to open water for releasing their sperm and eggs. We reasoned that mobile species might be able to jump ship and change tide pool if their home gets too warm or begins to dry out. Sessile organisms that are fixed to the rock do not have that luxury and so we expect to see fewer mussels, anemones and barnacles in tide pools in the high intertidal compared to lower tide pools that are submerged for longer each tide. Larger tide pools are presumably less stressful and so we think we will find that sessile organisms are more common in the larger tide pools that we surveyed. A few more hours of data preparation and analysis and we will know if our suspicions were correct. We are eager to ...

A softgel is an oral dosage form for medicine similar to capsules. They consist of a gelatin based shell surrounding a liquid fill. Softgel shells are a combination of gelatin, water, opacifier and a plasticiser such as glycerin or sorbitol. Softgels are produced in a process known as encapsulation using the Rotary Die Encapsulation process invented by Robert Pauli Scherer. The encapsulation process has been described as a form/fill/seal process. Two flat ribbons of shell material are manufactured on the machine and brought together on a twin set of rotating dies. The dies contain recesses in the desired size and shape, which cut out the ribbons into a two-dimensional shape, and form a seal around the outside. At the same time a pump delivers a precise dose of fill material through a nozzle incorporated into a filling wedge whose tip sits between the two ribbons in between two die pockets at the point of cut out. The wedge is heated to facilitate the sealing process. The wedge injection causes ...
We investigate a procedural shape modeling approach based on reaction-diffusion equations and physically based growth of thin shells. This inspiration of this work comes from the morphological development of living tissues, such as plants leaves. There are numerous choices that can be made in assembling a computer simulation of these growth system. We explore two main approaches, one where a reaction-diffusion simulation is first run with the results used to identify regions of growth, and the other where we simulate shell growth concurrently with a reaction-diffusion simulation in the manifold. We demonstrate that a variety of interesting shapes can be grown in this manner, and provide some intuition to the challenging problem of associating changes in parameter settings with the final shape. ...
Populations of the gastropod Nucella lapillus are polymorphic for shell color, with light-colored shells predominating on warmer, wave-protected shores and dark-colored shells limited primarily to cooler, wave-exposed shores. During thermal stress, darker shells attain higher body temperatures than lighter shells. These results suggest that heat stress may determine field distribution patterns. However, there is currently little evidence of physiological consequences of thermal stress in these organisms. Following the guiding hypothesis that heat stress leads to cellular energy depletion, we explored whether the central energy regulator AMP-activated Protein Kinase (AMPK) is activated by heat stress. We compared this response in both color morphs to the expression of a heat shock protein (Hsp70) in field and lab experiments. For the field experiments, two color morphs of snails were tethered to a rock and exposed to heat stress on two hot summer days. For the laboratory experiments, snails were exposed

Its an old Chesapeake tradition, paving driveways, decorating gardens and the bases of rural mailboxes with oyster shells. But it may give way to a different purpose; helping to restore the Chesapeakes decimated oyster population. Heres why.. Oyster shells are just the thing an oyster farmer needs to spread across three or four acres of leased bottom in a Chesapeake tributary to form a bed for baby oysters to attach themselves and grow. But shells are hard to come by (see: tradition and decimated population), and expensive; $3 to $4 a bushel. And thats where homeowners like Jeff and Lisa Duffy come in.. ...
The SSNMR characteristics of healthy vertebrate bone are strongly conserved between anatomical location, species and age group. Thus, the 13C spectrum and 13C{31P} REDOR responses of trout bone are virtually indistinguishable from those of mammalian bone [4,8]. In contrast, the spectra of the two brachiopod materials are strikingly different from each other (except for the chitin components). Most of the differences relate to protein signals, which supports previous work demonstrating differing amino acid composition of the shells [22,23]. Unfortunately, in complex materials such as these it is very difficult to understand more about the protein constituents beyond the fact that they must differ significantly. Nevertheless, SSNMR provides a rapid spectral fingerprint by which qualitative differences between shell materials can be ascertained non-destructively. On the other hand, the fluoroapatitic mineral phases of each shell give XRPD patterns, and 31P SSNMR spectra (data not shown), which ...
There is an increasingly urgent need to understand and predict how organisms will cope with the environmental consequences of global climate change. Adaptation in any form can be mediated by genetic adaptation and/or by phenotypic plasticity. Disentangling these two adaptive processes is critical in understanding and predicting adaptive responses to environmental change. Usually, disentangling genetic adaptation from phenotypic plasticity requires common garden experiments conducted under controlled laboratory conditions. While these experiments are powerful, it is often difficult to translate the results into natural populations and extrapolate to naturally occurring phenotypic variation. One solution to this problem is provided by the many examples of invasive species that exhibit wide phenotypic variation and that reproduce asexually. Besides selecting the appropriate in situ model, one must carefully choose a relevant trait to investigate. Ecomorphology has been a central theme in ...

The first grant season of the year is over. I got a couple grants and did not get a few others.

Either way, I am glad that this part of the year is mostly over, as I am ready to start working with bugs and plants again!. This summer, I will be working on a common garden experiment based at one of the local field sites at Cornell University. For this type of experiment, I collect milkweed seeds from multiple locations and grow them in a common environment. By removing the variation caused by developing under different environments, I am mostly observing plant variation caused by genetic factors. There are many applications for this type of experiments from developing new plant varieties in agriculture to ...

Are you interested in what some of Sidneys fellows are researching? Have a quick look and see. There is also a link at the bottom to take you to the fellows research page.. Dr Rose Thorogood: In behavioural ecology, we study how behaviour evolves and is shaped by natural selection. However, in the face of rapid environmental change, animals often do best if they can change their behaviour accordingly. How do individuals evolve behaviour that is flexible, and what are the consequences of changes in one species behaviour for others? I research co-evolution: the actions of one species have evolutionary consequences for another, and I test how birds, in particular, acquire information about their environment to modify their behaviour. I am most interested in the evolutionary consequences of information use in the interactions between cuckoos (brood parasites) and their hosts, and predators and their prey, with a second important goal of using information ecology theory to solve conservation ...
Aim: Myocardial infarction is caused after impairment of heart wall muscle following an immense cell loss and also when the myocardial tissue is lacking the inherent capacity to regenerate for normal functioning of myocardium. An immediate challenge in cardiac regeneration is to devise a strategy that leads to a reproducible degree of cardiac differentiation. We have speculated that ex vivo pretreatment of adipose-derived stem cells (ADSCs) using 5-azacytidine and a suitable patterned nanofibrous construct could lead to cardiomyogenic differentiation and results in superior biological and functional effects on cardiac regeneration of infarcted myocardium. Materials & methods: Polyglycerol sebacate/gelatin fibers were fabricated by core/shell electrospinning with polyglycerol sebacate as the core material and gelatin as the shell material. Patterning of the core/shell fibers to form orthogonal and looped buckled nanostructures was achieved. Results: Results demonstrated that the buckled ...

These odd enemies are found only in and around the subterranean aquaculture farms beyond the lighthouse in the Fishing Hamlet; the subtype living in large spiral shells are immobile and can be picked off with almost complete impunity, but those without shells are considerably more mobile and can become troublesome in groups. Both variants have very low HP and defense, but youll usually have to deal with them in large numbers due to the tight quarters in which youll encounter them. In certain spots they can be found hanging from rafters and will drop down to attack as you pass by, so keep your eyes not only on the path ahead of you, but the space above you as well ...
A novel microcapsule of polysulfide sealant was designed and prepared by in situ polymerization technology with poly(urea-formaldehyde) resin(PUF) as shell material and polysulfide rubber as core material under the weak acid conditions. The microencapsulating process of core material, the morphology and chemical structure of microcapsule were monitored and characterized by surface observation and Fourier-transform infrared spectroscopy(FTIR) techniques, respectively. At the earlier stage of emulsification and dispersion, it was found that the particle diameter of dispersed polysulfide rubber decreased nonlinearly with the increase of PVA-124 concentration and PVA-124 was the best emulsifying agent among the various stabilizers studied. Through a large number of experiments, the following optimized conditions for the emulsification and dispersion of polysulfide rubber were obtained:using 1.5%(mass fraction) PVA solution as dispersion phase and PhMe as diluter, stirring speed 500 r/min and ...
The effect of the storage and release of dye on the structure of PMSQ can be compared by considering the stability of this polymer at the temperatures used in this work. PMSQ capsules were collected in a cross-linker (distilled water) and possessed good mechanical properties and chemical durability [24]. In addition, PFH is an unreactive, immiscible and inert liquid, and does not change the composition of the shell material [23]. After the release of dye molecules, no apparent difference in morphology can be observed within the experimental time span. Furthermore, it has been reported that glass-transition temperature of PMSQ polymers is in the range of 80-120°C [25,26], and its coefficient of thermal expansion is approximately 19 × 10−6°C [27] and on pyrolysis of PMSQ to ceramic, the first mass loss of PMSQ can be observed only at higher than 199°C [28].. Suspension of hollow capsules in a solution of the material to be encapsulated results in the yield spontaneous filling of the capsules ...

  • We reveal that this symbiosis is a discrete four-level food chain, wherein bacteria function as the apex carnivores, animals and fungi are meso-consumers, and the sole herbivores are fungi. (pnas.org)
  • Together, our findings demonstrate that bacteria, fungi, and animals can be integrated within a food chain, effectively uniting the macro- and microbiome in food web ecology and facilitating greater inclusion of the microbiome in studies of functional diversity. (pnas.org)
  • While most foraging skills are picked up from mom, some bottlenose dolphins seem to look to their peers to learn how to trap prey in shells. (sciencenews.org)
  • Mineralized exoskeletons first appeared in the fossil record about 550 million years ago, and their evolution is considered by some to have played a role in the subsequent Cambrian explosion of animals. (thefullwiki.org)
  • All the major animal phyla that exist today -- about three dozen -- evolve from these Cambrian faunas . (pbs.org)
  • While scientists now know that animal life existed prior to the Cambrian explosion, the diversity of life that evolves during its 10 million years remains significant. (pbs.org)
  • Environmental factors alone, however, cannot explain why major animal phyla have not evolved in the 500 million years or so since the Cambrian explosion. (pbs.org)
  • These siphons act as snorkels, enabling the animal to continue to draw in a water current containing oxygen and food into their bodies. (wikibooks.org)
  • A single donor phenotype could therefore produce multiple pearl phenotypes at the scale of the saibo position, mirroring its original activity at the mantle position level and the colour and shape of the shell. (nature.com)
  • The colour of egg shells is spotted cream. (fao.org)
  • Moreover, D1DRs gate the stability of these cocaine-induced changes at glutamatergic synapses in the accumbens shell by utilizing multiple temporally distinct mechanisms, which has implications for the treatment of cocaine craving and addiction. (pubmedcentralcanada.ca)
  • Neural encoding of cocaine-seeking behavior is coincident with phasic dopamine release in the accumbens core and shell. (nih.gov)
  • Multifunctional yolk/shell-structured hybrid nanomaterials have attracted increasing interest as theranostic nanoplatforms for cancer imaging and therapy. (springer.com)
  • In this study, we report the general synthetic strategy of chelator-free zirconium-89 ( 89 Zr)-radiolabeled, TRC105 antibody-conjugated, silica-based yolk/shell hybrid nanoparticles for in vivo tumor vasculature targeting. (springer.com)
  • Three types of inorganic nanoparticles with varying morphologies and sizes were selected as the internal cores, which were encapsulated into single hollow mesoporous silica nanoshells to form the yolk/shell-structured hybrid nanoparticles. (springer.com)
  • This strategy could be applied to the synthesis of other types of yolk/shell theranostic nanoparticles for tumor-targeted imaging and drug delivery. (springer.com)
  • br/>On Monday, Pakistan had violated ceasefire in Uri sector of North Kashmir also in which two persons including a soldier were injured while army had retaliated leading to fierce shelling from both the sides. (kashmirtimes.com)

  • Royal Dutch Shell says it plans to repurchase $25 billion of its stock over the next two years after announcing that second-quarter earnings rose 30 percent as energy prices surged. (journalrecord.com)
  • Royal Dutch Shell will return to paying pure cash dividends and step up its investment in cleaner energy as it turns a corner after more than two years of cost cuts and disposals prompted by weak oil prices. (reuters.com)
  • Weak oil prices prompted an austerity drive at Royal Dutch Shell. (reuters.com)
  • Then Agriculture Minister David Carter said during the third reading debate on the Animal Welfare Amendment Bill that the law change would send a clear message that serious offending against animals was unacceptable and would not be tolerated. (nzherald.co.nz)
  • The penalties imposed by the courts in animal welfare cases remain today - as they were before the law change - very lenient. (nzherald.co.nz)
  • Other cohorts of rats received nor-BNI directly into the NAc shell or core and entered into ShA or LgA. (jneurosci.org)
