Opportunities for classical biological control of weeds in European overseas territories [PDF]

open access: yes, 2008
European overseas territories are home to biodiversity and endemism of worldwide importance, vastly superior to that of continental Europe as a whole. They are, however, much more threatened by invasive species, including hundreds of alien invasive plant

Travelling waves in a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait [PDF]

open access: yes, 2012
We consider a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait. To sustain the possibility of invasion in the case where an underlying principal eigenvalue is negative, we ...

Global determinants of home range sizes in felids: Evidence of human disturbance impact

open access: yesJournal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.

Biocultural synthesis of adolescence: a roadmap to advance the field Synthèse bioculturelle de l'adolescence : une feuille de route pour faire avancer la recherche

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Adolescence is an expansive, dynamic period within the life course, covering a broad age range (10‐24 years) and a cascade of biological and cultural changes. However, biocultural approaches to adolescence have been less well developed within existing research compared to child and adult counterparts.

‘Vitamins’, shortcuts, and athletic citizenship in Ethiopia and Cameroon: considering sporting ethics beyond biomedicine « Vitamines », courts‐circuits et citoyenneté sportive en Éthiopie et au Cameroun : l’éthique du sport, au‐delà de la biomédecine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article argues that the current way of thinking about ethics in sport in primarily biomedical terms, and in particular in terms of the presence of particular pharmaceutical substances, fails to account for broader notions of sporting ethics and fairness in the Global South.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

open access: yesInsect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

‘Missing persons’: Ancient legacies of human–environment interaction in tropical natural properties inscribed under the 1972 World Heritage Convention

open access: yesArchaeometry, EarlyView.
Abstract Cultural and natural values form the core of World Heritage designation. Properties displaying both values, however, comprise a fraction of inscriptions (currently c. 3%) to the World Heritage List. In 1992, when that fraction stood at c. 5%, adoption of the popular ‘cultural landscapes’ category of cultural heritage in 1992 was therefore ...
