Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

La Biodiversidad

open access: yesGestión y Ambiente, 2011
La biodiversidad es un suceso ecológico realmente sorprendente en tanto existe una extraordinaria homogeneidad química y bioquímica de base, en todos los seres vivos. Se considera que se dan por lo menos tres fenómenos que la explican: la evolución darwiniana, es decir, la evolución ramificada; el «acoplamiento estructural» según lo define H. Maturana;

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Presence of Nationally Banned Carbamates and Organophosphate Pesticides in Wild Carnivores, Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.
