Ecological and functional effects of habitat conversion and seasons on fruit‐feeding butterfly assemblages in tropical dry forests Efeitos ecológicos e funcionais da conversão do habitat e da sazonalidade sobre assembleias de borboletas frugívoras em florestas tropicais secas

open access: yesEcological Entomology, EarlyView.
Land‐use change and seasonality shape the taxonomic, functional and phylogenetic diversity of fruit‐feeding butterflies in tropical dry forests. Pastures reduce phylogenetic diversity and increase wing fluctuating asymmetry, while taxonomic and functional diversity is greater in the wet season than in the dry season.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1345-1356, July 2026.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Spectromicroscopy Analysis of Chicken Egg Shells

open access: yesX-Ray Spectrometry, Volume 55, Issue 4, Page 587-596, July/August 2026.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Challenges and Advances Driving Studies on Aquatic Insects of the Order Coleoptera

open access: yesFreshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Aquatic beetles (Coleoptera) are known for their high taxonomic and ecological diversity and their sensitivity to environmental changes, making them key bioindicators in ecological assessments. However, numerous knowledge gaps persist globally.

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Ecological Niche Divergence in an Invasive Non‐Native Shrub: Implications for Risk Assessments

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
The worldwide spread invasive shrub Nicotiana glauca (tree tobacco) underwent divergent niche shifts across two of its invaded regions. In the mediterranean region it presents high thermal seasonality and low thermal seasonality in the Caatinga (Brazil).

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

A Bourdieusian Approach to the Demobilisation of Brazil's AIDS Movement

open access: yesSociology of Health &Illness, Volume 48, Issue 4, May 2026.
ABSTRACT This article offers a Bourdieusian analysis of the demobilization of Brazil's AIDS movement, once a globally celebrated force in shaping innovative, rights‐based public health responses. Drawing on extensive qualitative data, I argue that the movement's decline cannot be explained solely by institutional co‐optation, biomedicalisation, or ...
