Environmental and human‐related gradients shape the community structure of medium and large terrestrial mammals in a central Amazonian white‐sand Forest

Journal of Animal Ecology, EarlyView.
This novel study examines how environmental and human‐related gradients influence habitat use and the community structure of medium and large terrestrial mammals in Central Amazonian white‐sand forests (campinaranas), one of the naturally rarest and least studied ecosystems in the Amazon region.

The inadequacies of the steppic savanna classification system to describe the vegetation of the semi-arid Caatinga of Brazil [PDF]

Rodriguésia
The steppic savanna term was originally employed to classify a single type of tropical vegetation in Africa, but it has been expanded by the pioneering RADAMBRASIL authors and it is currently used to classify the vegetation of the Caatinga in ...

Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

Integrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Aligning Transnational due Diligence: The EU Deforestation Regulation and Brazil's Fragmented Beef Governance

Global Policy, EarlyView.
ABSTRACT Transnational due diligence regulations, such as the European Union Regulation on Deforestation‐Free Products (EUDR), are reshaping sustainability governance by transforming voluntary norms into binding global rules. Yet, their effectiveness depends on how well they align with domestic governance systems and on the power asymmetries that ...

How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?

Zoologia (Curitiba), 2015
Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals.

Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.

Global harms, local profits: How the uneven costs of natural disasters affect support for green political platforms

American Journal of Political Science, EarlyView.
Abstract Large‐scale fires are becoming increasingly common due to climate change. While conventional wisdom suggests that firsthand experiences with natural disasters foster green coalitions by raising awareness of environmental degradation, we propose an alternative view: Natural disasters can heighten the perceived trade‐off between economic ...

Protected areas on international borders show uneven conservation outcomes

Conservation Biology, EarlyView.
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...
