Conceptualization and Measurement of Habitat Fragmentation from the Primates’ Perspective
Springer Science and Business Media LLC - Tập 30 - Trang 497-514 - 2009
Víctor Arroyo-Rodríguez, Salvador Mandujano
Habitat fragmentation is one of the principal threats to primates. Studies of primates in fragments usually conclude that fragmentation negatively affects some aspect of their biology or ecology. Nevertheless, the definition and quantification of fragmentation vary considerably among studies, resulting in contradictions and results that are difficult to interpret. We here 1) discuss the problems a...... hiện toàn bộ

Aggression and Reconciliation in Cebus capucinus
Springer Science and Business Media LLC - Tập 23 - Trang 979-998 - 2002
Jean-Baptiste Leca, Isabelle Fornasieri, Odile Petit
Most data relating to aggressive and conciliatory behaviors are from Old World primates. We recorded agonistic interactions and post-conflict behaviors in a group of 12 white-faced capuchins (Cebus capucinus). After a conflict, we followed the aggressee as the focal individual during a 10-min postconflict period. We also conducted matched-control observations on the same individual. Conflicts invo...... hiện toàn bộ
Ring-Tailed Lemur Home Ranges Correlate with Food Abundance and Nutritional Content at a Time of Environmental Stress
Springer Science and Business Media LLC - Tập 24 - Trang 969-985 - 2003
Anne S. Mertl-Millhollen, Erica S. Moret, Dina Felantsoa, Hantanirina Rasamimanana, Kathryn C. Blumenfeld-Jones, Alison Jolly
In order to determine whether ring-tailed lemurs (Lemur catta) adapt their ranging and select an optimal diet at a time of food shortage, we observed two adjacent troops in Berenty Reserve, Madagascar for over 250 h. The troops, created by a recent fission, ranged through closed canopy gallery forest next to a river and open forest away from the river. We conducted the study in September–October, ...... hiện toàn bộ
It’s Tough Out There: Variation in the Toughness of Ingested Leaves and Feeding Behavior Among Four Colobinae in Vietnam
Springer Science and Business Media LLC - Tập 29 - Trang 1455-1466 - 2008
B. W. Wright, L. Ulibarri, J. O’Brien, B. Sadler, R. Prodhan, H. H. Covert, T. Nadler
Colobines are similar in their exploitation of a high percentage of leaf matter. However, this observation obfuscates interesting differences among genera of Southeast Asian colobines in morphology and behavior that may be reflected in the degree to which they rely on mastication or gut volume and gut retention time when ingesting and digesting leaves. We detail the use of a laboratory-based metho...... hiện toàn bộ
Soils Consumed by Chimpanzees of the Kanyawara Community in the Kibale Forest, Uganda
Springer Science and Business Media LLC - Tập 26 - Trang 1375-1398 - 2005
William C. Mahaney, Michael W. Milner, Susanne Aufreiter, R. G. V. Hancock, Richard Wrangham, Sean Campbell
We previously reported on a study of 4 soils that chimpanzees of the Kanyawara community in the Kibale National Park, Uganda consumed on a near-daily basis. We suggested that iron was a possible chemical stimulus in association with high quantities of Si:Al = 1:1-dominated clay minerals in the consumed material. To test our initial findings, we analyzed 18 samples from the same general area includ...... hiện toàn bộ
Testing the Influence of Habitat Structure and Geographic Distance on the Genetic Differentiation of Mouse Lemurs (Microcebus) in Madagascar
Springer Science and Business Media LLC - Tập 36 - Trang 823-838 - 2015
Bettina M. Scheel, Johanna Henke-von der Malsburg, Peggy Giertz, S. Jacques Rakotondranary, Bernhard Hausdorf, Jörg U. Ganzhorn
The evolution of the high level of microendemism in Madagascar’s biota remains poorly understood. Allopatric speciation or adaptations to local conditions along continuous gradients are two mechanisms that could have contributed to the extraordinary radiation of lemurs. Here we tested whether mouse lemurs (Microcebus griseorufus) occurring across three adjacent but distinct vegetation formations (...... hiện toàn bộ
Predicting the Competitive Regime of Female Colobus vellerosus from the Distribution of Food Resources
Springer Science and Business Media LLC - Tập 28 - Trang 315-336 - 2007
T. L. Saj, P. Sicotte
We examined the spatial and temporal distribution of the foods of ursine colobus (Colobus vellerosus) at Boabeng-Fiema, Ghana as a means to predict the monopolizablity and usurpability of their food resources. Recent evidence suggests that food may not be limiting for folivorous primates, and that male sexual coercion may be a more important influence on folivore social organization. To address th...... hiện toàn bộ
