Age variation in the body coloration of the orb-weaver spider Alpaida tuonabo and its implications on foraging
(Nature Publishing Group, 2018-02-26)
Spiders show a repertoire of strategies to increase their foraging success. In particular, some orb-weaver spiders use attractive body colorations to lure prey. Interestingly, coloration varies with age in many species, ...
Influence of human activities on some medium and large-sized mammals’ richness and abundance in the Lacandon Rainforest
(Journal for Nature Conservation, 2016-12)
We evaluated the influence of six human activities (related variables) on the richness and abundance of large and medium-sized mammals in the southern portion of the Lacandon Rainforest, including protected and non-protected ...

Consistency in bird use of tree cover across tropical agricultural landscapes
(Ecological Applications, 2014-01-01)
In tropical regions where forests have been replaced by agriculture, the future of biodiversity is increasingly dependent on the presence of remnant forest patches and on-farm tree cover within agricultural landscapes. ...
Factors influencing the occurrence of the Endangered Baird's tapir Tapirus bairdii: Potential flagship species for a Costa Rican biological corridor
(ORYX, 2014)
Dengue fever is the fastest spreading, most prevalent and deadly arthropod-borne viral disease world-wide, present in over 125 countries. In 2013, Costa Rica is experiencing the highest number of Dengue infec-tions since ...

The role of fragmentation and landscape changes in the ecological release of common nest predators in the neotropics
(PeerJ, 2014-07)
Loss of large mammalian carnivores may allow smaller mesopredators to become abundant and threaten other community members. There is considerable debate about mesopredator release and the role that other potential factors ...
