Human land-use changes the diets of sympatric native and invasive mammal species. [PDF]
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.

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds. [PDF]
A large chromosomal inversion in common quails (Coturnix coturnix) is associated with phenotypic traits. In a wintering population in southern Spain, we found all three karyotypes coexisting but showing differences in migratory behavior and diet, as exemplified by the isotopic signature.

Orbital Forcing and Evolution of the Southern African Monsoon From Late Miocene to Early Pliocene
Abstract The late Miocene‐early Pliocene (7.4‐4.5 Ma) is a key interval in Earth's history where intense reorganization of atmospheric and ocean circulation occurred within a global cooling scenario. The Southern African monsoon (SAFM) potentially played an important role in climate systems variability during this interval.

Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Abstract As coastal ecosystems become widely recognized for their capacity to sequester carbon (blue carbon), standard accounting methodologies for the generation of carbon credits are being developed. To ensure the applicability of these standards across blue carbon ecosystems, we investigated organic carbon provenance and burial in salt marshes and ...

Seasonal dietary niche contraction in coexisting Neotropical frugivorous bats (Stenodermatinae)
Abstract Tropical dry forests are characterized by punctuated seasonal precipitation patterns that drive primary production and the availability of fruits, seeds, flowers, and insects throughout the year. In environments in which the quantity and quality of food resources varies seasonally, consumers should adjust their foraging behavior to maximize ...
