Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators

Animal Conservation, EarlyView.
We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

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

Animal 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 “

A sexual/apomictic consensus linkage map of Eragrostis curvula at tetraploid level

BMC Plant Biology
Background Apomixis is an asexual reproduction process that allows plants to bypass meiosis and fertilization, resulting in clonal seeds that are genetically identical to the maternal genotype.

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Populismo y recursos naturales

Raigal, 2018
En el presente trabajo realizamos una comparación de las tres experiencias populistas clásicas de América Latina, es decir, los gobiernos de Lázaro Cárdenas en México (1934-1940), Juan Domingo Perón en Argentina (1945-1955) y Getulio Vargas en Brasil (1951-1954); a la luz de sus políticas en materia de recursos naturales.

Recursos naturales y volcanismo: Turismo volcánico

Enseñanza de las Ciencias de la Tierra, 2015
Yellowstone (USA), a giant volcanic caldera, was the first National Park created in the world in 1872. Volcanism and tourism go hand in hand in many volcanic areas of the world, especially in volcanic oceanic islands. These islands, including Canary Islands or Hawaii, have many factors favouring mass tourism, especially the weather, beaches and ...
