Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves

Conservation Biology, EarlyView.
Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.

An integrated approach to balance freshwater connectivity restoration and invasion risk

Conservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Estudio de la concentración del mineral de estaño de la mina Santa Elisa (Zamora) [PDF]

, 1988
Este estudio muestra que el mineral es fácil de concentrar permitiendo una posible etapa de preconcentración gravimétrica a tamaños inferiores a 8 mm., y que el tamaño de liberación de la casiterita es de 1 mm. Además, hace posible un deslamado fácil y

Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

Conservation Biology, EarlyView.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Harnessing social media data to track species range shifts

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

Spatial identification of areas suitable for other effective area‐based conservation measures in the European Union

Conservation Biology, EarlyView.
Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
