Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, Volume 51, Issue 5, Page 1025-1035, October 2026.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

open access: yesJournal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments.

NUMBER OF COWS AND BAGS NEEDED TO ESTIMATE in situ DRY MATTER DEGRADATION OF KINGGRASS (Pennisetum purpureum) LEAVES

open access: yesTropical and Subtropical Agroecosystems, 2012
The number of bags to be incubated per sample, and the number of fistulated cows needed to estimate in situ ruminal degradation of Kinggrass (Pennisetum purpureum) dry matter (DMD %) were determined. Three rumen-fistulated cows and 10 bags per incubation

Spatio‐Temporal Dynamics of Asian Clams in Two Mediterranean Canals

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The rapid spread of the non‐native invasive Asian clam (Corbicula spp.) has been linked to the catastrophic decline of native freshwater mussel assemblages in Europe and North and South America. This study evaluates the spatio‐temporal dynamics and shell size structure of the Asian clam within two Mediterranean canals: Canal Imperial de Aragón

Compresion y analisis de imagenes por medio de algoritmos para la ganaderia de precision

open access: yesCoRR, 2021
The problem that we want to solve in this project of the subject of Data Structures and Algorithms, is to decipher some images, which have in them animals, being more specific, bovine animals; in which it is necessary to identify if the animal is healthy, that is to say, if it is in good conditions to be taken into account in the process of selection ...

Cacao Rootstock Selection Resistant to Ceratocystis cacaofunesta at the INIAP Germplasm Collection, Ecuador

open access: yesPlant Pathology, Volume 75, Issue 5, September‐October 2026.
The genetic improvement programme, aimed at identifying cocoa rootstocks resistant to Ceratocystis cacaofunesta, has enabled the selection of a series of genotypes with high levels of resistance within the INIAP germplasm bank. The use of improved and certified material in the clonal propagation of plants guarantees the productive life of our cocoa ...
