Evidence for a fisher‐designed solution to manta and devil ray bycatch in tuna fisheries

open access: yesConservation Biology, EarlyView.
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

Threats to and management of Natura 2000 protected areas relative to agricultural practices

open access: yesConservation Biology, EarlyView.
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Unexpected consequences of taxonomic misidentification for the conservation of an endangered species

open access: yesConservation Science and Practice, EarlyView.
This article reports on the unexpected consequences of taxonomic misidentification of the endangered fir Abies hickelii in eastern Mexico. Misidentification led to positive outcomes, such as unintentional population increases through reforestation, but also negative outcomes, including logging and altered demographic structure.

Risk factors associated with owner‐reported sleep disturbances in Nordic horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Very little is known about sleep disturbances in horses, although several management or animal‐based factors may contribute to an increased risk of disturbances. Objectives To investigate factors related to rest and sleep behaviour of horses kept in stalls as perceived by Nordic horse owners or caretakers and their association with ...

Mapping the density of giant trees in the Amazon

open access: yesNew Phytologist, EarlyView.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

open access: yesNew Phytologist, EarlyView.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

Legacy effect of non‐native Eucalyptus trees on the regeneration of coastal plant communities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction When the elimination of a non‐native plant is insufficient to promote the regeneration of indigenous vegetation, secondary interventions, such as the removal of non‐native plant litter, may be appropriate due to legacy effects.
