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 ...

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Biodiversidad y Cambio Climático

Apuntes de Ciencia & Sociedad, 2015
La rica variedad de vida en la Tierra estuvo siempre expuesta a un clima cambiante. La necesidad de adaptarse a los nuevos patrones de temperatura y de precipitaciones tiene una influencia importante en los cambios evolutivos de las especies de plantas y animales.El cambio climatico plantea ahora una de las amenazas principales para la diversidad ...

Relationship between spatial and social phenotypes in an avian scavenger

Journal of Animal Ecology, EarlyView.
A method is applied to distinguish interaction rates that would be expected given animals' movements from those that exceed expected values due to incidental contact. The relationship between space use and both observed and non‐incidental social network position varies between social situations.

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 ...

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

A biodiversidade

, 2007
"[…]. O estudo da diversidade biológica – ou biodiversidade – e da ecologia está intimamente relacionado com a promoção da conservação da natureza. O termo "biodiversidade" nasceu no forum "BioDiversity" em Washington, em 1986, e foi pela primeira vez publicado em 1988 pela National Academy Press (Wilson, 1988 a, b).

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.
