A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region

open access: yesPest Management Science, EarlyView.
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Water Losses and Environmental Efficiency in Urban Water Supply Systems: A Comparative Assessment for Spain and Portugal

open access: yesSustainable Development, EarlyView.
ABSTRACT Water losses are a critical environmental and operational challenge, especially in regions exposed to increasing water stress. This study assesses the environmental productivity of municipal water supply services in Spain and Portugal during the period 2014–2022, explicitly treating losses as an undesirable output.

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

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

open access: yesWildlife 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.

open access: yesEstudios de Derecho, 1921
Como nos han informado que cursa actualmente en el Congreso un proyecto que reglamenta esta importante materia, hemos creído conveniente insertar el informe que presentó la comisión nombrada por el Senado de 1914 obre otro proyecto de la misma índole presentado a esa H. Corporación por el Sr. Ministro de Agricultura y Comercio de ese año.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

When “Rescue” Means Exile: The Urgency of Science‐Based Protocols for Large Carnivore Interactions and Coexistence in the Neotropics

open access: yesAnimal Conservation, EarlyView.
Using the recent case of an Andean jaguar translocated hundreds of kilometers to a distinct savanna ecosystem in Colombia, we critique the prevalent “Reactive Removal” model often framed misleadingly as “rescue.” We contrast this approach, which disregards local adaptation, creates ecosystem mismatches, and blocks natural range recovery, with a needed “
