Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, EarlyView.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

Ibis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

First Mediterranean record and north‐eastern range extension of the African seahorse Hippocampus algiricus

Journal of Fish Biology, EarlyView.
Abstract The African seahorse Hippocampus algiricus has been considered restricted to the eastern Atlantic coast of Africa, with occasional records in Macaronesian archipelagos. The species is currently classified as Vulnerable by the International Union for Conservation of Nature (IUCN).

Hierarchical Modelling of Aquatic Species Distributions

Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Species Distribution Models (SDMs) have traditionally been developed in a terrestrial context, and their application to aquatic ecosystems presents unique challenges. These include predicting species distributions across spatially constrained environments and incorporating environmental drivers that operate across nested spatial scales. We

BIMr2: Inference of migration rates and their drivers from multilocus genotypes

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2330-2342, August 2026.
Abstract Understanding how environmental factors drive recent migration is crucial for predicting species' responses to habitat change and for informing conservation strategies. There is one method available (BIMr) aimed at identifying the environmental factors associated with migration patterns using genetic data.

El Impacto del Bono Demográfico en el Sector Educativo Argentino. Periodo 2010-2040. Un Abordaje Interdisciplinario

International Journal of Sociology of Education, 2015
Conforme avanza la transición demográfica existe un periodo de tiempo de descenso sostenido de la fecundidad, mientras tanto aún no es muy grande el peso relativo de la población mayor de edad y, por tanto, la principal proporción de la población se ...

Past and Future Shifts in Marine Species Distributions Across Two South American Large Marine Ecosystems

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim To quantify temporal (Middle Holocene, historical and future) and spatial changes in habitat suitability for marine species in two South American Large Marine Ecosystems, and to evaluate the ecological consistency of long‐term Species Distribution Model projections using archaeological records as independent evidence of past species ...

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Dos modelos de transición demográfica en América Latina

Perfiles Latinoamericanos, 1995
La transición demográfica en América Latina empezó en 1930 con la baja de la mortalidad, seguida en 1965 por la baja de la fecundidad, paralelamente a un intenso proceso de modernización de las sociedades y economías del subcontinente.
