Local Environmental Variables Predict Fish Species Richness and Composition in Sand Beaches of a Neotropical River

open access: yesRiver Research and Applications, Volume 41, Issue 9, Page 1949-1958, November 2025.
ABSTRACT Local and regional species diversity is influenced by historical factors, resource availability, biotic interactions, the presence of resources, and adequate environmental conditions. We evaluated the effects of local environmental variables and spatial structure on fish species richness and composition along sandy beaches of a Neotropical ...

Spatial distribution pattern of the endangered endemic cycad Ceratozamia fuscoviridis (Zamiaceae) in central Mexico

open access: yesPlant Species Biology, Volume 40, Issue 6, Page 572-583, November 2025.
Spatial distribution pattern were studied for Ceratozamia fuscoviridis, an endangered species in Mexico, based on Ripley's K t and K 12 analysis. Clumped spatial distribution patters was found in individuals of all populations, suggesting low interaction with predators/dispersers and/or evidence of suitable microsites for cycads.

Ecological and Morphological Traits Determine Community‐Wide Responses of Birds to Climate Change in a Tropical Dry Forest

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim We evaluate the potential consequences of climate change on the Caatinga Dry Forest, asking how the future climate would affect its avifauna under three different carbon emission scenarios. First, we evaluate potential climate‐induced distributional changes.

The silent guardians of the Quebrada de Humahuaca: the ethnobotany of the “cardón” (Trichocereus atacamensis, Cactaceae) among indigenous people of the Department of Tilcara (Jujuy, Argentina)

open access: yesBonplandia, 2018
The “cardón”, Trichocereus atacamensis, is an emblematic species in the Quebrada de Humahuaca (Jujuy, Argentina). However, although data can be found scattered throughout the literature, its ethnobotany has never been studied in depth.

The preference for energetic resources is positively associated with predatory activity in ants

open access: yesEcological Entomology, Volume 50, Issue 5, Page 921-932, October 2025.
We found that ants exhibit a stronger preference for foraging for carbohydrates and lipids (energetic nutrients) compared to amino acids. The increase in foraging for energetic nutrients compared to amino acids is positively correlated with foraging in larvae (insect predation). The nutrient preference between foraging for energetic nutrients and amino

Hacia un enfoque más-que-utilitario en etnobiología

open access: yes, 2021
El hecho de percibir a las plantas y los animales como "recursos" para los humanos está vinculado a uno de los principales constructos del discurso modernista: la dicotomía entre naturaleza y sociedad, una dicotomía que ha tendido a dominar la ciencia ...

Climate Change in the Brazilian Cerrado: A Looming Threat to Terrestrial Biodiversity

open access: yesWIREs Climate Change, Volume 16, Issue 5, September/October 2025.
Due to climate change, the Brazilian Cerrado, a global biodiversity hotspot, is becoming hotter and drier, with longer and more intense dry seasons. This alters biodiversity by altering plant physiology, ecological interactions, and species distribution, creating more homogeneous and less diverse communities.

„Szőlővel fekszik szőlővel ébred”

open access: yesPólusok Folyóirat, 2023
Az elmúlt évtizedekben az ökológia és a néprajz-antropológia találkozása egy virágzó új kutatási irányzatot eredményezett, az etnobiológia és az etnoökológia szakterületét, a hagyományos ökológiai tudás és a helyi tudások kutatását. E kutatási eredmények
