The entanglement between the IUCN Red List and international biodiversity law

open access: yesConservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species (red list) is of fundamental importance for nature conservation and biodiversity protection. I considered the interaction between the red list and international biodiversity law (IBL), the legal regime that aims to protect biodiversity at a global level ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, EarlyView.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Analysis of nifH-RNA reveals phylotypes related to Geobacter and Cyanobacteria as important functional components of the N2-fixing community depending on depth and agricultural use of soil [PDF]

open access: yes, 2017
In this survey, a total of 80 787 reads and 28 171 unique NifH protein sequences were retrieved from soil RNA. This dataset extends our knowledge about the structure and diversity of the functional diazotrophic communities in agricultural soils from ...

Gender Dimensions of Support for Local Policy: Resident, Policymaker, and Policy Gender

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT There is a well‐established triadic relationship between satisfaction with public services, trust in leaders, and policy support in developed democracies. This study takes a novel approach by considering how gender is associated with the strength and direction of these connections, an element underexplored in the literature.
