Digest: Sexually selected traits can affect individual fitness and trait evolution in a butterfly species.

Wedell and Kemp ([2024]. Examined the importance of female sexual preferences for male UV reflectance on offspring viability and the evolution of male traits in the butterfly Eurema hecabe. Female preferences were found to have multiple consequences, including increased trait value, higher offspring viability, and reduced mutational load.

Barcoding Brazilian mammals to monitor biological diversity and threats: Trends, perspectives, and knowledge gaps.

DNA barcoding and environmental DNA (eDNA) represent significant advances for biomonitoring the world's biodiversity and its threats. However, these methods are highly dependent on the presence of species sequences on molecular databases. Brazil is one of the world's largest and most biologically diverse countries.

Morphological traits explain the individual position within resource-consumer networks of a Neotropical marsupial.

Knowledge regarding the influence of individual traits on interaction patterns in nature can help understand the topological role of individuals within a network of intrapopulation interactions. We tested hypotheses on the relationships between individuals' positions within networks (specialization and centrality) of 4 populations of the mouse opossum and their traits (i.e.

Non-target effects of agri-environmental schemes on solitary bees and fungi in the United Kingdom.

Agri-environmental schemes (AES) are used to enhance pollinator diversity on agricultural farms within the UK. Though the impacts of these schemes on archetypal pollinator species such as the bumblebee () and honeybee () are well-studied, the effects on non-target bee species like solitary bees, in the same environment, are generally lacking. One goal of AES is to alter floral provision and taxonomic composition of plant communities to provide better forage for pollinators, however, this may potentially impact other ecological communities such as fungal diversity associated with plant-bee communities.

Mapping global conservation priorities and habitat vulnerabilities for cave-dwelling bats in a changing world.

Research and media attention is disproportionately focused on taxa and ecosystems perceived as charismatic, while other equally diverse systems such as caves and subterranean ecosystems are often neglected in biodiversity assessments and prioritisations. Highlighting the urgent need for protection, an especially large fraction of cave endemic species may be undescribed. Yet these more challenging systems are also vulnerable, with karsts for example losing a considerable proportion of their area each year.

DarkCideS 1.0, a global database for bats in karsts and caves.

Understanding biodiversity patterns as well as drivers of population declines, and range losses provides crucial baselines for monitoring and conservation. However, the information needed to evaluate such trends remains unstandardised and sparsely available for many taxonomic groups and habitats, including the cave-dwelling bats and cave ecosystems. We developed the DarkCideS 1.

The structure of tropical bat-plant interaction networks during an extreme El Niño-Southern Oscillation event.

Interaction network structure reflects the ecological mechanisms acting within biological communities, which are affected by environmental conditions. In tropical forests, higher precipitation usually increases fruit production, which may lead frugivores to increase specialization, resulting in more modular and less nested animal-plant networks. In these ecosystems, El Niño is a major driver of precipitation, but we still lack knowledge of how species interactions change under this influence.

Conserving the forgotten: New insights from a Central African biodiversity hotspot on the anthropogenic perception of nocturnal primates (Mammalia: Strepsirrhini).

The growing dependence of villagers on local forests (food, wood, etc.) makes the comparative assessment of the perceptions they have of the forest and its wildlife increasingly important for setting conservation priorities. While hunting and habitat loss are important threats to primates' existence worldwide, more attention has been focused on diurnal species, while little is known about their nocturnal counterparts.

Assessing the impact of taxon resolution on network structure.

Constructing ecological networks has become an indispensable approach in understanding how different taxa interact. However, the methods used to generate data in network research vary widely among studies, potentially limiting our ability to compare results meaningfully. In particular, methods of classifying nodes vary in their precision, likely altering the architecture of the network studied.

Availability of food resources and habitat structure shape the individual-resource network of a Neotropical marsupial.

Spatial and temporal variation in networks has been reported in different studies. However, the many effects of habitat structure and food resource availability variation on network structures have remained poorly investigated, especially in individual-based networks. This approach can shed light on individual specialization of resource use and how habitat variations shape trophic interactions.

Spatiotemporal and demographic variation in the diet of New Zealand lesser short-tailed bats ().

Variation in the diet of generalist insectivores can be affected by site-specific traits including weather, habitat, and season, as well as demographic traits such as reproductive status and age. We used molecular methods to compare diets of three distinct New Zealand populations of lesser short-tailed bats, . Summer diets were compared between a southern cold-temperate (Eglinton) and a northern population (Puroera).

Sexual dimorphism in Sturnira lilium (Chiroptera, Phyllostomidae): can pregnancy and pup carrying be responsible for differences in wing shape?

Competition is one of the most cited mechanisms to explain secondary sexual dimorphism in animals. Nonetheless, it has been proposed that sexual dimorphism in bat wings is also a result of adaptive pressures to compensate additional weight caused by fetus or pup carrying during the reproductive period of females. The main objective of this study is to verify the existence of sexual dimorphism in Sturnira lilium wings.
