Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Taxonomic, phylogenetic and functional diversity patterns of Saturniidae moth communities along a tropical forest recovery gradient in Ecuador

open access: yesInsect Conservation and Diversity, EarlyView.
Diverse Saturniidae moth communities are found in naturally recovering tropical forests in Ecuador. Community composition showed a gradual turnover with strongest differences between old‐growth forest and active agriculture, but only weak differences in taxonomic, phylogenetic and functional diversity. While our results suggest that Saturniidae are not

Multinational enterprises and disadvantaged communities in emerging markets: A review and theoretical framework

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract Multinational enterprises (MNEs) face growing pressures from stakeholders to address global challenges and alleviate inequalities endured by disadvantaged communities in the regions where they operate. Given the fragmented conceptual approaches to understanding the relationships between MNEs and these communities, the complex mechanisms ...

Politicisation and Agricultural (Post‐)Exceptionalism in EU–Mercosur Association Agreement Negotiations

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This article examines how the politicisation of EU trade policy – defined by heightened public salience, stakeholder polarisation and contestation – reshapes agricultural lobbying strategies, with a particular focus on the EU–Mercosur Association Agreement.

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

open access: yesJournal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

open access: yesJournal of Fish Biology, EarlyView.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger
