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
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
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.

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
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).

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
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 ...
