Rarity as an indicator of endangerment in neotropical frogs
(Elsevier B.V., 2014-11-01)
Anurans are endangered worldwide and declining populations are in need of urgent conservation management. Optimal conservation actions ideally rely on basic ecological and natural history data, such as population size, ...
Specialization and Rarity Predict Nonrandom Loss of Interactions from Mutualist Networks
(American Association for the Advancement of Science, 2012-03-23)
The loss of interactions from mutualistic networks could foreshadow both plant and animal species extinctions. Yet, the characteristics of interactions that predispose them to disruption are largely unknown. We analyzed ...

Climate fluctuations as a cause of rarity in fairy armadillos
(Elsevier Gmbh, 2015-07)
Despite having a moderately large distributional area, both the pink fairy armadillo (Chlamyphorus truncatus) and particularly the Chacoan fairy armadillo (Calyptophractus retusus), which are among the least known xenarthrans, ...
