Effects of socioeconomic and human-modified landscape variables on medicinal species richness at a macroscale: the case of the Caatinga, Brazil [PDF]

Journal of Ethnobiology and Ethnomedicine
Background Ethnobiological studies at local scales have shown that knowledge of medicinal species tends to decrease as socioeconomic status and the extent of human-modified landscapes increase.

Can family structure and contact with natural resources influence young people’s knowledge about medicinal plants? An approach in the Northeast of Brazil [PDF]

Journal of Ethnobiology and Ethnomedicine
Background Individuals develop crucial survival knowledge in the juvenile phase, including understanding medicinal plants. The family context or contact with resources can influence this dynamic knowledge.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum [PDF]

Journal of Fish Biology, Volume 108, Issue 6, Page 2053-2068, June 2026.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Healing with Risks: How Zoonotic Potential Influences the Use of Wild Mammals in Traditional Medicine [PDF]

Pathogens
Most infectious diseases affecting humans are zoonotic in origin, with mammals serving as the main reservoirs. Frequent interactions between humans and animals, especially in the context of their use for food, medicine, and other purposes, pose ...

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes [PDF]

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Species Extirpation and Colonization Reveal Mixed Homogenization and Differentiation Across Terrestrial Taxa After One of the World's Largest Tailings Dam Failures [PDF]

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Fundão tailings‐dam failure (2015)—study area and impact gradient. Regional maps locate the Rio Doce Basin in southeastern Brazil and the Fundão dam (red cross), with the black rectangle marking the extent of the main map. The main map follows the downstream tailings pathway along the river corridor (plume highlight).

Climate, Not Soil, Drives the Distribution of Two Closely Related Worm Lizards [PDF]

Ecology and Evolution
A central challenge in ecology is understanding how closely related species coexist, and sister species—with which they share a closely related evolutionary history—provide a powerful system for testing niche overlap and segregation.

Bioecological representations and social characteristics of students influence their attitudes toward wild vertebrates

Journal of Ethnobiology and Ethnomedicine, 2023
Background The origin of different human emotions directed towards animals (whether in the utilitarian, affective, conflictual, or cosmological context) is strongly influenced by sociocultural factors, although our genetic predispositions also play an ...

Patterns associated with hunting with dogs in a semiarid region of northeastern Brazil

Journal of Ethnobiology and Ethnomedicine, 2022
Background Hunting has been an important cultural and subsistence activity for the survival of the human population. In the Brazilian semiarid region (Caatinga), the extreme seasonal changes and socioeconomic conditions have made local people dependent ...
