Habitat Amount Shapes Ant Diversity in the Central Amazon

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Energy‐Based Semiactive Control Algorithms for Nonlinear Framed Structures Using the Force Analogy Method

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
This study presents a novel framework for developing closed‐form semiactive control algorithms specifically designed for structures exhibiting inelastic response during seismic events. The proposed approach leverages the force analogy method (FAM) to represent structural nonlinearity through equivalent forces rather than continuous stiffness matrix ...

Local and landscape features of urban fragments determine the occurrence of stingless bees As características locais e paisagísticas dos fragmentos urbanos determinam a ocorrência de uma espécie de abelhas sem ferrão

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1027-1036, November 2025.
Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

open access: yesAustral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Population genetics and the role of dispersal barriers in the Antarctic springtail Kaylathalia klovstadi (Collembola, Isotomidae)

open access: yesJournal of Zoology, Volume 326, Issue 2, Page 109-120, June 2025.
Our study investigates the role of Tucker and Whitehall Glaciers as barriers to the dispersal of the springtail Kaylathalia klovstadi and examines its genetic population structure using mitochondrial DNA markers. Genetic analyses of 62 individuals from six populations reveal new insights into the species’ diversity and distribution, challenging ...
