Phylogenetic and Functional Originality Shape Species Positions in Flea–Mammal Networks Across Biogeographic Realms

open access: yesIntegrative Zoology, EarlyView.
The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...

Fissidens in the Neotropics

open access: yes, 1990
The land areas of the Western Hemisphere south of the United States support over 276 species of Fissidens (Wijk et al. 1962, 1969). This number is approximately 30% of the total number of species known.

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

open access: yesIntegrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

A bryophyte checklist of the ecological reserve of Gurjaú, Pernambuco, Brazil

open access: yes, 2005
A bryophyte checklist of the Ecological Reserve of Gurjaú (08º10’00'’-08º15’00"S; 35º02’30"- 35º05’00"W), a remnant of the Atlantic Forest in the State of Pernambuco, has been compiled.

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

open access: yesAnimal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Epiphytic bryophytes of Monteverde, Costa Rica

open access: yes, 2001
A survey of the literature and collections in the Monteverde Cloud Forest Preserve and adjacent pastureland yielded a total of 198 epiphytic bryophyte taxa (120 species of hepatics in 50 genera, 77 species of moss in 48 genera, and 1 hornwort): 178 in ...

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

FLORA AND VEGETATION OF THE SEASONALLY DRY TROPICS IN MEXICO: ORIGIN AND BIOGEOGRAPHICAL IMPLICATIONS

open access: yesActa Botanica Mexicana, 2012
Entre las diversas ideas que se han propuesto para explicar la gran diversidad biológica de México está la que afirma que ésta es el resultado del contacto de las biotas neotropical y eártica; sin embargo, esta explicación relacionada con el gran ...
