Comparing species and evolutionary diversity metrics to inform conservation

Diversity and Distributions, Volume 29, Issue 2, Page 224-231, February 2023., 2023
Abstract Phylogenetic diversity (PD) is an important measure for identifying areas of conservation. Phylogenetic diversity is a robust biodiversity metric because it accounts for the relationships among species, and not just the number of species. For this reason, it is an essential element for conservation planning.

Rasgos biológicos de macroinvertebrados de ríos subtropicales: patrones de variación a lo largo de gradientes ambientales espacio-temporales

Ecología Austral, 2012
Los rasgos biológicos reflejan las tácticas de los organismos como respuesta al cambio ambiental. Analizamos la organización funcional del grupo EPT (Ephemeroptera, Plecoptera y Trichoptera) en una cuenca subtropical de montaña para evaluar si sus ...

Genetic assignment of illegally trafficked neotropical primates and implications for reintroduction programs [PDF]

arXiv, 2019
The black and gold howler monkey (Alouatta caraya) is a neotropical primate that faces the highest capture pressure for illegal trade in Argentina. We evaluate the applicability of genetic assignment tests based on microsatellite genotypic data to accurately assign individuals to their site of origin.

Taxonomy in the light of incongruence: An updated classification of Malvales and Malvaceae based on phylogenomic data

TAXON, EarlyView.
Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex evolutionary history for the order, including localised phylogenetic discordances among nuclear loci.

Next‐generation sequencing sheds new light on a major lineage of Acanthaceae, clarifying previously uncertain relationships in Barlerieae

TAXON, EarlyView.
Abstract The Acanthaceae tribe Barlerieae is an understudied lineage that consists of ca. 500 species, many of which are rare and range restricted. Though understudied, it is clear that many species play vital roles in tropical ecosystems, including supporting a wide range of pollinators and herbivores. The tribe contains 13 genera, the two largest and

Anthropogenic disturbances alter the trophic niche structure and ecological relationships of understory bat communities in the Ecuadorian Andean Chocó

Wildlife Biology, EarlyView.
Human disturbances have reduced the three basic niche dimensions for the survival of some mammalian species (space, time, and resources). Anthropic activities cause the extinction of ecological functionalities faster than species extinctions. In this study, we identified four types of habitats in the Ecuadorian Andean Chocó: primary forest (PF ...

Habitat variables influencing bird assemblage patterns across maize and legume fields before and after harvest in West Africa

Wildlife Biology, EarlyView.
Though agriculture has been linked to the decline in bird populations due to the associated changes in vegetation structure and composition, its potential to sustain birds has been explored over time. A sustainable agricultural landscape should be one that has the capacity to support bird species all year.
