Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, EarlyView.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Translocation of livestock‐raiding lions under specific conditions can mitigate conflict

open access: yesConservation Science and Practice, EarlyView.
Human‐wildlife conflict is a pervasive threat that imperils many carnivore species worldwide, and although translocation is often used as a conflict mitigation strategy, it is widely regarded as ineffective. Here, we demonstrate that careful selection of suitable release sites can improve outcomes, as 80% of stock‐raiding lion translocations in ...

Avaliação do risco de extinção do veado-campeiro Ozotoceros bezoarticus Linnaeus, 1758, no Brasil

open access: yesBiodiversidade Brasileira, 2012
O estado de conservação no Brasil, das duas subespécies do veado-campeiro, Ozotoceros bezoarticus (Linnaeus, 1758), que ocorrem no país, foi avaliado de acordo com os critérios da IUCN (2001), com base nos dados disponíveis até 2010.

Balancing risk and opportunity: Nasute termite responses to predator and competitor chemical cues

open access: yesEcological Entomology, EarlyView.
Nasutitermes corniger discriminates between heterospecific chemical cues during foraging, showing non‐random resource selection based on predator and competitor information. Predator chemical cues consistently reduce food resource selection, indicating avoidance driven by perceived predation risk rather than direct encounters.

Forest type modulates mammalian responses to megafires

open access: yesScientific Reports
Although considered an evolutionary force responsible for shaping ecosystems and biodiversity, fires’ natural cycle is being altered by human activities, increasing the odds of destructive megafire events.

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

open access: yesIbis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

open access: yesInsect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.
