When Resources Become Limited: Trophic Niches Shift From Generalism to Specialization in Dung Beetles (Coleoptera: Scarabaeinae)

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT Resource availability and predictability can shape trophic organization in ecological communities. In livestock pastures, cattle dung represents a highly abundant and predictable trophic subsidy for dung beetles, potentially promoting generalist foraging strategies. Here, we test how cattle exclusion affects trophic organization in dung beetle

Fluid Toxicities: Violent Affective Ecologies in Cartagena, Colombia

open access: yesAntipode, Volume 58, Issue 5, September 2026.
ABSTRACT Water is at the centre of climate change emergency concerns in coastal cities. It constitutes here a fluid entry point to investigating the socio‐ecological politics of toxicities for residents dwelling with and against contaminated waters in Cartagena, Colombia's urban extensions.

Diversidad de anfibios

open access: yes, 2021
La distribución de la an biofauna santafesina (ranas, sapos, escuerzos y cecilias) sigue un patrón latitudinal, con una disminución de la riqueza de especies hacia el sur y una penetración de muchos taxones por medio del corredor biológico que representa el río Paraná y sus humedales (Ghirardi y López, 2017).

Antipredatory Strategies of Anurans: An Updated Conceptual Review

open access: yesEthology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

Peep, Squeal and Claim: Complex Territorial Call Emission Across Social Contexts in a Neotropical Torrent Frog

open access: yesEthology, Volume 132, Issue 8, Page 565-577, August 2026.
Males of Hylodes perere emit territorial calls ranging from simple to complex combinations of peep (A) and squeal (B) notes, often accompanied by visual signals. Because note A resembles advertisement call notes whereas note B resembles fighting calls, variations in territorial calls may represent a behavioral continuum conveying different levels of ...

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

open access: yesJournal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

open access: yesJournal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...
