Enforcing environmental law in the Amazon

People and Nature, EarlyView.
Abstract This article identifies the underlying obstacles to enforcement of laws against environmental crimes such as illegal logging, mining and ranching. With four departments (provinces) from Colombia as case studies, it assesses enforcement of the country's main environmental law, Law 2111, which is one of Latin America's strongest. The article has

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Evaluation of reduced amino acids diets added with protected protease on productive performance in 25-100 kg barrows

Austral Journal of Veterinary Sciences, 2019
The objective of this research was to evaluate the effect of adding protected protease to low-amino acids (AA) diets on the growth performance of barrows.

Efecto de la paridad, aborto y padecimientos posparto sobre parámetros reproductivos y productivos en vacas lecheras, en dos ganaderías de Sonsonate, El Salvador

Revista Minerva, 2020
La investigación se realizó en dos ganaderías lecheras (ambas colindantes), ubicadas en el departamento de Sonsonate, El Salvador. La ganadería 1 cuenta con 140 vacas en ordeño y la ganadería 2, con 750 vacas en ordeño.

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Disentangling Multitrophic Interactions: How Vegetation Cover, Wild Boar, Deer, and Predators Shape Rodents Activity and Acorn Dispersal

Integrative Zoology, EarlyView.
Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.

Susceptibility to milk fat depression in dairy sheep and goats: Individual variation in ruminal fermentation and biohydrogenation

Journal of Dairy Science, 2023
: Small ruminants are susceptible to milk fat depression (MFD) induced by marine lipid supplementation. However, as observed in dairy cows, there is wide individual variation in the response to MFD-inducing diets, which may be due to individual ...

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

Ecological Entomology, EarlyView.
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.

An Isotope‐Based Snapshot Reveals the Combined Influence of High‐Elevation Recharge and Local Return Flows on Groundwater Across Guatemala City

Hydrological Processes, Volume 40, Issue 6, June 2026.
Representation (not to scale) of potential high elevation recharge and low elevation return flows within the Guatemala City metropolitan area. ABSTRACT Guatemala City is the most populous urban center in Central America. In this urban center, groundwater extraction within the last 40 years has substantially declined water table levels and accelerated ...

Problemática de la ganadería extensiva en España

Estudios Geográficos, 1996
La ganadería extensiva constituye un aprovechamiento ganadero claramente diferenciado de aquel otro basado en la intensificación de las producciones y desvinculado de bases territoriales concretas.
