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
Marine mollusc shell growth has been widely measured using fluorochrome marking. In order to test the efficiency and reliability of calcein staining on P. margaritifera shells and pearls, the present study examined two administration methods, different concentrations and several immersion times.Immersion in a 150 mg.L-1 calcein solution for 12 h to 24 h appeared to be the best method for marking P. margaritifera shells. For pearl marking, injection of a 200 mg.L-1 calcein solution into the pearl pouch was the optimal method. Calcein marking was then used to measure the influence of food resource levels on the shell growth. Groups of 23-month-old P. margaritifera were fed at three trophic levels for two months. The two highest food levels tested (6 000 ...

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 ...
But what about exploration firms that drill only a few holes each month?. In that scenario Stromberg believes Data Mosaic can still show its strength. You may need to look at all the drill holes from a single area together, thats where the fast processing comes in. But even on the scale of a few holes, it can be very valuable in terms of cost-saving, time-saving for geologists, interpreting the data from the drill holes and allowing faster decision-making, such as whether to continue or stop drilling, or where to drill the next hole, she says.. While the above datasets are indeed huge, those case studies come from fairly homogenous environments. The much greater tectonic activity in the Andes likely leads to much more complex stratigraphy. Could this test the limits of Data Mosaics processing power?. Stromberg thinks not, and expects it to work just as well in such environments because CSIRO has tested it on drill holes and data from many different rock types and ore types.. I would argue ...

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

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 ...
