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.

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds. [PDF]
Ecol EvolA 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
Paleoceanography and Paleoclimatology, Volume 38, Issue 9, September 2023., 2023 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.

Ecology, Volume 104, Issue 5, May 2023., 2023 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

Limnology and Oceanography, Volume 67, Issue S2, Page S6-S18, November 2022., 2022 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)
Biotropica, Volume 52, Issue 4, Page 749-757, July 2020., 2020 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 ...

Fraccionamiento isotópico: efecto de la composición química
Estudios Geologicos, 1989 El fraccionamiento isotópico de los elementos puede estar afectado por distintos factores, tales como: Presión, Estructura Cristalina, Temperatura y Composición química. Este trabajo de revisión pretende estudiar la influencia en la composición isotópica
