Multifaceted Assessment of Amazonian Tree Diversity Reveals Pervasive Impacts of Human Modification. [PDF]
Glob Chang BiolAmazonian forests impacted by humans have a reduced and different group of tree species than those forests that have never been impacted. The trees present in forests impacted by humans also have different evolutionary histories and functional characteristics.

Effect of uneven tolerance to human disturbance on dominance interactions of top predators. [PDF]
Conserv BiolAbstract Anthropogenic activities may alter felid assemblage structure, facilitating the persistence of tolerant species (commonly mesopredators), excluding ecologically demanding ones (top predators) and, consequently, changing coexistence rules. We aimed to determine how human activities influence intraguild relationships among top predators and ...

People and Nature, Volume 5, Issue 6, Page 1804-1821, December 2023., 2023 Abstract Environment‐facing interventions impact the distribution, use of and access of natural resources and have important implications for all dimensions (material, relational, quality of life) of human well‐being (HWB). Yet conventional impact metrics routinely surpass the non‐material impacts which may be particularly salient in rural contexts ...

Life history induces markedly divergent insect responses to habitat loss. [PDF]
J Anim EcolThis study pioneers the use of deep learning to rapidly assess over 22,000 Amazonian insects, revealing life history‐dependent winners and losers from forest loss. It shows that terrestrial insects decline while aquatic insects thrive, with body size influencing dispersal, offering key insights for biodiversity conservation in tropical fragmented ...

Functional Ecology, Volume 37, Issue 11, Page 2967-2976, November 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Floral traits are assumed to be the main determinants of plant's pollinator spectrum, yet a majority of temperate plant species possess traits allowing to a certain degree of generalisation of their pollinator spectrum.

Brazil's Amazon Fund: A “Green Fix” between Offset Pressures and Deforestation Crisis
Antipode, Volume 55, Issue 6, Page 1686-1710, November 2023., 2023 Abstract Emissions trading and nature‐based solutions, particularly REDD+, have lent themselves to the critical literature on the “socioecological fix” in neoliberal capital accumulation and state regulation. Prone to reversals, land conflict, and leakage, these mechanisms displace the burden of carbon emissions reductions to global South countries ...

CAPM, Dominancias Estocásticas & Diversificación
UDA AKADEM, 2020 El artículo expone de forma aplicativa a la teoría de diversificación del portafolio, cuyos cimientos se trasladan a Markowitz (1952). Acorde a esto, inicialmente se expusieron a grandes rasgos las bases de Capital Asset Pricing Model (CAPM), así como de la diversificación. Además, se explican ideas como las de dominancia estocástica, de primer orden;
