Abstract:
... (1) The focus on floral functional traits and their variability has been significantly lower than when compared to other plant organs. Here, we focused on the variability of four novel floral chemical traits. We aimed to assess the level of interspecific variability of total non-structural carbohydrates (TNC) and total phenolic compounds (TPh) in the flowers of woody species. (2) We collected data ...

Abstract:
... Our knowledge of the factors affecting species abundances is mainly based on time‐series analyses of a few well‐studied species at single or few localities, but we know little about whether results from such analyses can be extrapolated to the community level. We apply a joint species distribution model to long‐term time‐series data on British bird communities to examine the relative contribution ...

Abstract:
... Variational properties hold a fundamental role in shaping biological evolution, exerting control over the magnitude and direction of evolutionary change elicited by microevolutionary processes that sort variation, such as selection or drift. We studied the genus Tyrannus as a model for examining the conditions and drivers that facilitate the repeated evolution of exaggerated, secondary sexual trai ...

Abstract:
... Living collections grown in outdoor landscapes within botanic gardens play an increasingly important role in ex situ species conservation, but there is little work predicting the survival of different plant species in these landscapes. Here we present an approach to predict the survival of plants grown from wild propagules in botanic gardens, based on climatic provenance. We developed mixed effect ...

Abstract:

Understanding cases in restoration and in agriculture in which species diversity improves productivity and ecosystem functioning is crucial due the need to restore degraded habitat and improve crop productivity for a growing human population. Reaching these diversity benefits is likely influenced by the dynamic of less negative interspecific than intraspecific interactions that promote diversity. ...

Dendroecological observations of tundra shrubs can provide insight into current and past growth and recruitment patterns, both key components for understanding and predicting ongoing and future Arctic shrub dynamics. However, generalizing these dynamics is ...

Abstract:
... Despite the role that goatfishes play in reef ecosystems, knowledge of their ecomorphological diversity remains scarce. Here, we explore the ecomorphology of six species of goatfishes living in sympatry at Toliara Reef (South-West of Madagascar) by using a combination of morphometric and isotopic (δ¹³C, δ¹⁵N and δ³⁴S) data. The shape of cephalic region was quantified by landmark-based geometric mo ...

Abstract:
... Sex allocation theory in simultaneous hermaphrodites predicts that optimal sex allocation is influenced by local sperm competition, which occurs when related sperm compete to fertilize a given set of eggs. Different factors, including the mating strategy and the ability to self‐fertilize, are predicted to affect local sperm competition and hence the optimal SA. Moreover, since the local sperm comp ...

Abstract:
... Experimental approaches to isolate drivers of variation in the carbon‐bound hydrogen isotope composition (δ²H) of plant cellulose are rare and current models are limited in their application. This is in part due to a lack in understanding of how ²H‐fractionations in carbohydrates differ between species. We analysed, for the first time, the δ²H of leaf sucrose along with the δ²H and δ¹⁸O of leaf ce ...

Abstract:
... A dominant perception is that small and motile ectothermic animals must use behavior to avoid exposure to critical or sub-critical temperatures impairing physiological performance. Concomitantly, volunteer exploration of extreme environments by some individuals may promote physiological adjustments and enhance ecological opportunity. Here we introduce to the literature a Thermal Decision System (T ...

Abstract:

Consumer‐resource interactions are often influenced by other species in the community, such as when neighbouring plants increase or reduce herbivory to a focal plant species (known as associational effects). The many studies on associational effects between a focal plant and some neighbour have shown that these effects can vary greatly in strength and direction. But because almost all of these stu ...

Abstract:

Trait‐based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared with interspecific variability. However, this assumption remains poorly tested across vertebrate animals where past studies routinely describe species according to mean trait values without expl ...

... The genus Nymphaea L. (water lily) is the most diverse genus in the family Nymphaeaceae, with more than 50 species worldwide, including 11 species distributed in Africa. The complex and variable morphology of Nymphaea makes it extremely difficult to accurately identify species based on morphological characteristics alone. DNA barcoding has the potential to identify species accurately. In this stud ...

In this study, microplasti ...

Abstract:
... Analysing variation in a species’ genomic diversity can provide insights into its historical demography, biogeography and population structure, and thus its ecology and evolution. Although such studies are rarely undertaken for parasites, they can be highly revealing because of the parasite's co‐evolutionary relationships with hosts. Modes of reproduction and transmission are thought to be strong ...
