Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Abundância e densidade de jacamins (Psophia spp.) em unidades de conservação na Amazônia brasileira

Biodiversidade Brasileira
Os jacamins (Psophia spp.) são aves terrícolas, endêmicas do bioma amazônico, que vivem em pequenos grupos sociais. São animais visados para caça e sensíveis à alteração de habitat, e quatro espécies do gênero são consideradas ameaçadas de extinção no ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

Risco e resiliência: uma revisão dos atributos funcionais que influenciam a vulnerabilidade ao fogo em mamíferos do Pantanal

Biodiversidade Brasileira
Em 2020, incêndios em vegetação queimaram aproximadamente 40 mil hectares e mataram 17 milhões de vertebrados. Esse evento catastrófico, caracterizado pelo comportamento extremo do fogo e facilitado pela combinação de matéria orgânica acumulada e seca ...

VTMaxBox: A reproducible practical tool for measuring voluntary thermal maximum in terrestrial ectotherms

Methods in Ecology and Evolution, EarlyView.
Abstract Thermal traits are central to understanding how ectotherms respond to environmental warming. However, not all thermal traits describe the same biological process. Critical thermal maxima quantify physiological failure, whereas preferred temperatures describe thermal selection under choice conditions.

Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

Animal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.
