Conservation evidence is biased but can support decision‐making for prevalent and severe threats in tetrapods

open access: yesJournal of Applied Ecology, Volume 63, Issue 3, March 2026.
Despite taxonomic and spatial biases, substantial conservation evidence is available to support decision‐making by practitioners, particularly for the most prevalent and severe threats. Given the current biodiversity crisis, it is critical that this information is more widely used and that coordination among academic and practitioner partners is ...

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

open access: yesAustral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

Trade,Tariffs and Total Factor Productivity: The Case of Spanish Firms [PDF]

open access: yes
The aim of this paper is to examine the sensitivity of total factor productivity (TFP) to foreign competition in the case of a European country. Using the Olley and Pakes (1996) method, we calculate the TFP of Spanish manufacturing firms and study the ...

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

open access: yesConservation Science and Practice, Volume 8, Issue 3, March 2026.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

Social media highlights the overlooked impact of cats on arthropods

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 460-465, March 2026.
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.
