Abstract:
... Evidence suggests that biodiversity supports ecosystem functioning. Yet, the mechanisms driving this relationship remain unclear. Complementarity is one common explanation for these positive biodiversity–ecosystem functioning relationships. Yet, complementarity is often indirectly quantified as overperformance in mixture relative to monoculture (e.g., ‘complementarity effect’). This overperformanc ...

Abstract:
... The root economics spectrum (RES) hypothesis predicts that fast‐growing tree species have short‐lived roots with high specific root length (SRL) to allow rapid resource uptake, and opposite trait expressions for slow‐growing species. Yet, the mixed support for this hypothesis suggests that trees can adopt alternative strategies to increase resource uptake, besides an increase in SRL. We combined a ...

Abstract:
... Morphology-based identification and classification of sponge species is complicated, because their morphological features are highly variable. Therefore, molecular markers are ideal tools for delimiting sponge species. In this study, we compared the variability of two sections of COI (the standard 5′-end fragment and the I3-M11 fragment) for closely related Baikal sponge species. Although the mean ...

Abstract:
... Phyllostomids (New World leaf-nosed bats) are the ecologically most diverse bat family and have undergone the most extensive adaptive radiation of any mammalian family. However comprehensive, multi-species studies regarding phyllostomid echolocation are scarce in the literature despite abundant ecological research. In this study, we describe the call structure and interspecific variation in call d ...

Abstract:
... Intraspecific morphological variation fundamentally influences individual resource exploitation. In plant–pollinator systems, variation in floral morphologies and pollinator mouthparts may affect pollinators' resource use. This relationship has frequently been studied across species, but hardly ever at the intraspecific level in natural circumstances. We studied flower visits of clouded Apollo but ...

Abstract:
... Feathers are essential for avian life, and factors affecting their integrity are important to understand their evolution. These factors should depend on, among other traits, species‐specific bacterial environments and life‐history characteristics. However, interspecific variation in feather deterioration, feather susceptibility to degradation by keratinolytic bacteria (degradability), and bacteria ...

Abstract:
... Zoraptera is one of the most enigmatic and least understood orders in insects. Based on a wide taxon sampling from all continents where the group is known, we applied a phylogenetic approach using multiple DNA sequences to elucidate species‐level relationships. The resulting phylogeny shows that Zoraptera is divided into three major clades, and that two comprise species distributed on different co ...

Behavioural responses to novel stimuli can differ strongly between closely related species; however, the ecological and evolutionary factors underlying these differences are not well understood, in part because most comparative investigations have focused on onl ...

In this study, we examined the effects of increased temperature (15, 20 and 25 °C) and different light levels (50, 200 μmol photons m⁻² s⁻¹) on two widely distributed diatoms, namely Phaeodactylum tricornutum and Thalassiosira weissflogii. Results showed that increasing light level counteracted the negative effects of high temperature on photosynthesis in both species, suggesting an antagonistic i ...

Although synchronized oscillations in abundance across spatially segregated populations are a quasi-universal phenomenon, understanding their consequences for the stability of natural systems remains a major challenge. Theory has shown that even low levels of dispersal can synchronize and destabilize populations at both local and global scales. However, little is known about how persistent spatial ...

Abstract:
... Charles Darwin, in his species notebooks, engaged seriously with the quinarian system of William Sharp Macleay. Much of the attention given to this engagement has focused on Darwin’s attempt to explain, in a transmutationist framework, the intricate patterns that characterized the quinarian system. Here, I show that Darwin’s attempt to explain these quinarian patterns primarily occurred before he ...

Abstract:
... Photosynthesis is the gateway of the Sun’s energy into the biosphere and the source of the ozone layer; thus it is both provider and protector of life as we know it. Despite its pivotal role we know surprisingly little about the genetic basis of variation in photosynthesis and the selective pressures giving rise to or maintaining this variation. In this review, I will briefly summarise our current ...

Abstract:
... Timberlake (1993) proposed that much learning research can be better understood in the context of behavior systems theory. Learning theories generally have not considered how procedures may interact with evolutionarily prepared foraging contexts, thereby leading to anomalous conclusions. An example of such a conclusion is the apparent species difference when given a choice between a lower percenta ...

Abstract:
... As the use of functional trait approaches is growing in fungal ecology, there is a corresponding need to understand trait variation. Much of trait theory and statistical techniques are built on the assumption that interspecific variation is larger than intraspecific variation. This allows the use of mean trait values for species, which the vast majority of trait studies adopt. We examined the size ...

Moreover, A. speciosus is a ground dweller, while A. argenteus commonly shows arboreal ...
