Enhancing multitasking capacity: An acoustic tagging and sampling methodology for the spiny butterfly ray (Gymnura altavela) in the Canary Islands

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
To overcome challenges in studying elusive benthic elasmobranchs, a comprehensive, rapid methodology was developed and applied to 133 Spiny Butterfly Rays in Gran Canaria and Tenerife between 2020 and 2024. This approach integrated internal tagging with acoustic and external T‐bar tags, alongside biological sampling and ultrasound assessments, all ...

Microtargeting for conservation

Conservation Biology, Volume 33, Issue 5, Page 1141-1150, October 2019., 2019
Abstract Widespread human action and behavior change is needed to achieve many conservation goals. Doing so at the requisite scale and pace will require the efficient delivery of outreach campaigns. Conservation gains will be greatest when efforts are directed toward places of high conservation value (or need) and tailored to critical actors.

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Efficiencies of and Motivations for Contracting Out in the Public Sector: The Case of Social Services in Spain

Public Administration, Volume 103, Issue 3, Page 693-706, September 2025.
ABSTRACT Debates on contracting out to the private sector is primarily focused on the cost efficiency of its provision, drawing on experiences with hard or technical services such as waste and water management. This paper focuses on a growing interest in the role and impact of sourcing decisions in softer or more human‐centered services, such as social
