Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

Conservation Biology, EarlyView.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Pour une Écologie des Somatiques?

Revista Brasileira de Estudos da Presença, 2014
Ce texte traite de la parenté conceptuelle et théorique entre Somatiques et Écologie scientifique. Après une définition de la notion scientifique d’écologie, il s’attache à définir trois notions clés de l’écologie: celle de potentiel, qui permet de ...

The fourth dimension in landscape analysis: changing of heritage and ecological values in the Évora cultural landscapes. [PDF]

, 2011
Time is one of the most important driving forces in Landscape Ecology. Time along with geosystem, biosystem and socialsystem determines landscape heterogeneity which reveals itself in different patterns and functions.

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

Conservation 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 ...

The Nature of the Emission Components in the Quasar/NLS1 PG1211+143 [PDF]

, 2001
We present the study of the emission properties of the quasar PG1211+143, which belongs to the class of Narrow Line Seyfert 1 galaxies. On the basis of observational data analyzed by us and collected from the literature, we study the temporal and ...

Teleost‐specific ictacalcins exhibit similar structural organization, cation‐dependent activation, and transcriptional regulation as human S100 proteins

The FEBS Journal, EarlyView.
Calcium‐binding S100 proteins are important mediators of inflammation in humans. Distant members of this family have been recently discovered in teleost fish but their resemblance to human proteins has not been explored yet. This study demonstrates that zebrafish‐specific S100i1 and S100i2 (ictacalcins) possess identical structural organization and ...

Accretion disk wind as explanation for the broad-line region structure in NGC 5548

, 2013
Supermassive black holes in the centers of active galactic nuclei (AGN) are surrounded by broad-line regions (BLRs). The broad emission lines seen in the AGN spectra are emitted in this spatially unresolved region.
