BACKGROUND AND AIMS: In heterostylous plant species, skewed morph ratios are not uncommon and may arise from a range of factors. Despite the recognized importance of skewed morph ratios on overall reproductive success within populations, little is known about the impact of skewed morph ratios on population genetic diversity and differentiation in heterostylous species. This study specifically aimed to clarify the effect of population size and morph bias on population genetic diversity and differentiation in the temperate forest herb Pulmonaria officinalis. This species is characterized by a distylous breeding system and shows morph-specific differences in reproductive success. METHODS: Genetic diversity was determined for 27 P. officinalis populations in northern Belgium by using eight recently developed microsatellite markers. Multiple regressions were used to assess the relationship between genetic diversity, morph bias and population size, and F(ST)-values were calculated for short- and ...

Pulmonarins A and B are two new dibrominated marine acetylcholinesterase inhibitors that were isolated and characterized from the sub-Arctic ascidian Synoicum pulmonaria collected off the Norwegian coast. The structures of natural pulmonarins A and B were tentatively elucidated by spectroscopic methods and later verified by comparison with synthetically prepared material. Both pulmonarins A and B displayed reversible, noncompetitive acetylcholinesterase inhibition comparable to several known natural acetylcholinesterase inhibitiors. Pulmonarin B was the strongest inhibitor, with an inhibition constant (Ki) of 20 μM. In addition to reversible, noncompetitive acetylcholinesterase inhibition, the compounds displayed weak antibacterial activity but no cytotoxicity or other investigated bioactivities.. ...

With Thegns help Ive been concentrating on clearing ivy in the spring garden. Seedlings of ash and sycamore have over-wintered there as well, and their bare stems defy attempts to dislodge them. Where I win the battle, I push crocus bulbs and snowdrops into the loosened soil, and plant wild primroses and spotted pulmonaria (lungwort) under the shelter of the trees. They look sad at the moment but, given gentle rain and warm sun in equal measure, will soon rally, providing nectar for emerging bees.. Such repetitive work gives me plenty of time to think about writing. Often, gardening is when the best ideas filter into my consciousness, bud, and blossom. Over subsequent weeks as the garden develops, I weed out the blind bulbs of ideas that lead nowhere, the weak seedlings that undermine the plot. I feed and tend the stronger saplings whose branches will bear the most fruit and the best storylines. In my garden, I flesh out my characters and prune those that get ahead of themselves.

Microclimatic gradients may have large influence on individual vital rates and population growth rates of species, and limit their distributions. Therefore, I focused on the influence of microclimate on individual performance and distribution of species. Further, I examined differences in how microclimate affect species with contrasting distributions or different ecophysiological traits, and populations within species. More specifically, I investigated the performance of northern and southern distributed forest bryophytes that were transplanted across microclimatic gradients, and the timing of vegetative and reproductive development among northern, marginal and more southern populations of a forest herb in a common garden. Also, I compared the landscape and continental distributions across forest bryophytes and vascular plants and, thus, their distribution limiting factors at different spatial scales. Lastly, I examined the population dynamics across microclimatic gradients of transplants from ...

There are many perennials to grow in a shady area. Although hostas are considered primarily foliage plants due to the wide variety of colorful foliage in different shapes and sizes, they also bloom and some have a good fragrance, too. Ferns make a nice complement to hostas and add additional all season interest and variety. Astilbes are often listed as shade plants, but will need some sun during the day to bloom their best. In addition to those big three perennials for shade, you might consider pulmonaria, lily of the valley, bleeding heart, Japanese anemone, tricyrtis, iris cristata, lamium, epimedium, phlox stolonifera, Solomons seal, and tiarella. There are also many woodland natives such as Virginia Bluebells that will thrive in the shady garden in a soil that is humusy and evenly moist yet well drained. Have fun experimenting ...

Many empirical studies have assessed fine-scale spatial genetic structure (SGS), i.e. the nonrandom spatial distribution of genotypes, within plant populations using genetic markers and spatial autocorrelation techniques. These studies mostly provided qualitative descriptions of SGS, rendering quantitative comparisons among studies difficult. The theory of isolation by distance can predict the pattern of SGS under limited gene dispersal, suggesting new approaches, based on the relationship between pairwise relatedness coefficients and the spatial distance between individuals, to quantify SGS and infer gene dispersal parameters. Here we review the theory underlying such methods and discuss issues about their application to plant populations, such as the choice of the relatedness statistics, the sampling scheme to adopt, the procedure to test SGS, and the interpretation of spatial autocorrelograms. We propose to quantify SGS by an Sp statistic primarily dependent upon the rate of decrease of ...

In the study of intrinsically stationary spatial processes, a new nonparametric variogram estimator is proposed through its spectral representation. The methodology is based on estimation of the variograms spectrum, here for the isotropic case, which is formulated in terms of solving a regularized inverse problem. We use quadratic programming to obtain the solution. The estimated variogram is guaranteed to be conditionally negative-definite, a key property of variograms. Simulation shows that our estimator is flexible and generally has smaller mean integrated squared error than the parametric estimator under model misspecification.. ...

How does climate change affect seed and pollen dispersal, an essential process for plant reproduction? To gain an in-depth understanding, Dr. Céline Born traveled to Marion Island in the sub-Antarctic Indian Ocean to study Azorella selago, a keystone plant species due to its critical importance to ecosystem function. Using the genotyped specimens found on the island, she is studying the impact of wind patterns on pollen dispersal of Azorella. Our research will be used for the development of a conservation plan for the sub-Antarctic region, which is particularly affected by climate change, she explained. This data will be used to predict colonization of the plant based on various global warming scenarios..

Climate warming is already influencing plant migration in different parts of the world. Numerous models have been developed to forecast future plant distributions. Few studies, however, have investigated the potential effect of warming on the reproductive output of plants. Understorey forest herbs in particular, have received little attention in the debate on climate change impacts. This study focuses on the effect of temperature on sexual reproductive output (number of seeds, seed mass, germination percentage and seedling mass) of Anemone nemorosa L., a model species for slow colonizing herbaceous forest plants. We sampled seeds of A. nemorosa in populations along a 2400 km latitudinal gradient from northern France to northern Sweden during three growing seasons (2005,2006 and 2008). This study design allowed us to isolate the effects of accumulated temperature (Growing Degree Hours; GDH) from latitude and the local abiotic and biotic environment. Germination and seed sowing trials were ...

Genetic diversity within species may promote resilience to environmental change, yet little is known about how such variation is distributed at broad geographic scales. Here we develop a novel Bayesian methodology to analyse multi-species genetic diversity data in order to identify regions of high or low genetic diversity. We apply this method to co-distributed taxa from Australian marine waters. We extracted published summary statistics of population genetic diversity from 118 studies of 101 species and | 1000 populations from the Australian marine economic zone. We analysed these data using two approaches: a linear mixed model for standardised data, and a mixed beta-regression for unstandardised data, within a Bayesian framework. Our beta-regression approach performed better than models using standardised data, based on posterior predictive tests. The best model included region (Integrated Marine and Coastal Regionalisation of Australia (IMCRA) bioregions), latitude and latitude squared. Removing

Inversion of aerosol optical depth (AOD) over bright land surface by optical remote sensing is particularly challenging because surface reflectance dominates the satellite signal. A structure function method is suitable and can effectively solve aerosol optical depth inversion in high reflectance areas. How to select d (the pixel distance between two pixels) value is one of the key problems with the structure function method. We present a method based on geostatistics, where variogram theory is referenced, to determine the pixel distance in structure function model for aerosol optical depth inversion. This method was validated by the Moderate Resolution Imaging Spectroradiometer (MODIS) 1 km resolution level 1B data from Beijing, China. The results indicate that the relationship between variogram and d in four different directions can be fitted by exponential function, of which correlation coefficients are all above 0.9. Compared with the MODIS aerosol product (MOD 04 product), the inversion AOD has

Citation: N/A Interpretive Summary: Technical Abstract: Spatiotemporal stability analyses are required to delineate areas of stable yield patterns for the application of precision farming management techniques. Spatial structure and temporal stability patterns were studied using 1995-1997 yield data for a field located near Story City, Iowa. Corn was grown during 1995-1996, and soybean during 1997. Yield was measured on 9 east-west transects, consisting of 25 yield blocks per transect. In order to compare the yield variability among different crops and years, data were detrended by median polishing. The resulting yield residuals were used in the subsequent spatial analysis. The trend surface analysis generated from the median polished data showed apparent large scale deterministic structure. The microsale stochastic structure was studied by variography. The variogram analysis showed strong spatial structure for the yield data. Spatial correlations were found to vary from about 40 m for corn to ...

Long-distance dispersal seems to be the main biogeographic event responsible for intriguing distribution patterns in plant groups in which sister taxa are separated by thousands of kilometers of distance across oceans and continents. The biotic and abiotic mechanisms behind such dispersal events are poorly understood and many attempts have been made to explain how plants can manage to disperse and survive these long journeys. The biogeographic history of Boraginaceae, a subcosmopolitan plant family with many disjunct clades, is here addressed and analyzed in the context of the different dispersal modes exhibited by the species. The lack of a clear pattern between the main dispersal events in Boraginaceae and the phylogenetic distribution of the dispersal modes indicates that no single dispersal mechanism can be associated with the events of dispersal in the family. Moreover, adaptations to different dispersal agents and unassisted dispersal modes in some clades might have promoted the diversification of

We all have a roll of duct tape lurking somewhere in our houses or sheds but youd be surprised at some of the ways this versatile tape can be used.

The genetic architecture elucidated for any trait is expected to be population specific. While among-population variation for genetic architecture has been detected by classic quantitative genetic approaches (e.g., Donohue et al. 2000; Morgan et al. 2001; Ashman 2003), little has been described on exactly how genetic architecture for a trait varies among natural or experimental populations; specifically, we would like to know which components of genetic architecture vary and in what way(s). Although the experimental design employed here precludes an examination of every aspect of genetic architecture, our analyses reveal the strongest evidence of genetic architecture variation by the mapping of different QTL in different populations (Table 2; Figure 4). Differences in the QTL identified for a trait among RIL populations may be due to differences in the power to detect QTL, environmental variation between mapping experiments, or the segregation of meaningful genetic variation among natural ...

Time series consist of values of a variable recorded in an order over a period of time. Such data arise in just about every area of science and the humanities, including econometrics and finance, engineering, medicine, genetics, sociology, environmental science. What makes time series data special is the presence of dependence between observations in a series, and the fact that usually only one observation is made at any given point in time. This means that standard statistical methods are not appropriate, and special methods for statistical analysis are needed. This course provides an introduction to time series analysis using current methodology and software. Topics covered are: descriptive methods, plots, smoothing, differencing; the autocorrelation function, the correlogram and variogram, the periodogram; estimation and elimination of trend and seasonal components; stationary processes, modelling and forecasting with autoregressive moving average (ARMA) models; spectral analysis, the fast ...
