Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

Expanding the Faunal Interpretation of the Cova Eirós (NW Iberia) Middle Paleolithic–Early Upper Paleolithic Record With ZooMS

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The Cova Eirós archaeopaleontological site preserves the most comprehensive archaeostratigraphic sequence in the northwestern Iberian Peninsula, with an exceptionally rich record spanning from the Mousterian to the Upper Paleolithic. The extensive fragmentation of the faunal record and the rich taxonomic diversity at this site have limited the

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

Oikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.
