Mothers against the natural order: Gender representations and desertion of identities in the drama of disinheriting a son in eighteenth‐century Barcelona  

open access: yesGender &History, EarlyView.
ABSTRACT The disinheritance of a firstborn son accustomed to the privileges of exclusion has for centuries been a dramatic event for families, especially if the decision was taken by a woman, the son's own mother. Very few dared to do so, because it symbolised a break with the notion of virtuous, compassionate motherhood; it represented a failure to be

Evaluating Wildlife Vulnerability to Mercury Pollution From Artisanal and Small-Scale Gold Mining in Madre de Dios, Peru

open access: yes, 2018
Illegal, artisanal and small-scale gold mining (ASGM) often occurs in remote highly biodiverse areas, such as the Madre de Dios region of Peru. Mercury used in gold mining bioaccumulates in the environment and poses developmental, hormonal, and ...

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China

open access: yesIntegrative Zoology, EarlyView.
Chorotype represents a fundamental concept for identifying groups of species that share similar distribution patterns. However, the last comprehensive revision of animal chorotypes in China was performed more than a decade ago. Here, we update the chorotype classifications for 1040 species and propose an updated zoogeographical regionalization scheme ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Dual Co/Photoredox‐Catalyzed Regio‐ and Stereoselective Synthesis of Highly Functional 1,3‐Dienes

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
A generic regio‐ and stereoselective protocol for the synthesis of functionalized 1,3‐dienes is presented that is facilitated via a dual Co/photoredox catalyst system while using modular 1,3‐enynes and unsaturated carbonyl derivatives as substrates. Key to the success of this transformation is the generation of a Co(III)H species that adds to the 1,3 ...
