Human land-use changes the diets of sympatric native and invasive mammal species. [PDF]
Ecol Evol, 2023 We simultaneously study the diet of nine native and two invasive mammal species inhabiting three different anthropogenic land‐uses across six bioclimatic regions using environmental DNA and stable isotope analysis. We show that land‐use influences the trophic relationships in invaded communities.

Flujo de compuestos organoclorados en las cadenas troficas de la cienaga de Santa Marta [PDF]
Caldasia, 1993 Monthly samples of seston and fish species of different throphic levels were done at the Ciénaga Grande de Santa Marta in orderto describe organochlorinated compounds dynamics. The fish used were: atlantic anchoveta, mulletand catfish.

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes. [PDF]
Ecol EvolPredator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Host-plant sex and phenology of Buddleja cordata Kunth interact to influence arthropod communities. [PDF]
Ecol EvolWe present the results of an empirical study that evaluates the effect of plant sex on its associated arthropod communities. Our results indicate that plant sex has a seasonal and alternating effect on the arthropod community diversity—male plants hosting a more diverse community of arthropods during the flowering season, while female plants do during ...

Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract Tropical montane bird communities are hypothesized to be highly sensitive to anthropogenic disturbance because species are adapted to a narrow range of environmental conditions and display high rates of endemism. We assessed avian sensitivity at regional and continental scales for a global epicenter of montane bird biodiversity, the tropical ...

Evaluación in vitro del efecto tóxico de una formulación comercial de glifosato de amonio sobre cinco especies representantes de diferentes hábitats y niveles tróficos [PDF]
, 2016 We evaluated the acute and chronic toxic effect in vitro of a commercial brand of ammonium salt of gliphosate over five species that occupy different trophic levels and physical environments: bacterioplankton (Vibrio fischeri), phytoplankton ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
