Primate Conservation

Published: May 2013

Primates are the most charismatic and among the most threatened of mammals, and are declining due to habitat loss, land use intensification and hunting. Apart from the concern for their conservation, it is also possible that ecological processes mediated by them, principally seed dispersal, could have knock-on effects on plant populations and forest composition. But are primates as vulnerable to forest disturbance as is often supposed? This Virtual Issue indicates that primates are somewhat adaptable and able to persist in degraded or fragmented forests, often by diversifying their food sources. Good news for primate conservation perhaps, but there is much to learn to improve land management for the benefit of primate populations.

Frugivory and Seed Dispersal by Brown Lemurs in a Malagasy Tropical Dry Forest
Hiroki Sato
Read it because... In Malagasy forests, the frugivorous species of Lemuridae are the largest-bodied seed dispersers. The author demonstrates key roles of brown lemurs — such as dispersal of large amount of seeds and large-sized seeds, improvement of seed germination, and a strong mutualism with an endemic large-seeded plant.

The Impact of Forest Disturbance on the Seasonal Foraging Ecology of a Critically Endangered African Primate
Claire E. Bracebridge, Tim R. Davenport and Stuart J. Marsden
Read it because... The dietary adaptability of the kipunji to seasonally fluctuating forest resources may buffer it against the impact of forest disturbance and ecological stress, including climate change. The authors show how understanding the importance of the major food species can help inform conservation strategies for species facing similar environmental threats.

Differences in Diet Between Spider Monkey Groups Living in Forest Fragments and Continuous Forest in Mexico
Oscar M. Chaves, Kathryn E. Stoner, and Víctor Arroyo-Rodríguez
Read it because... The authors found that food availability for spider monkeys was lower in fragments than in continuous forest. As result, monkeys in fragments diversified their diet, increased consumption of leaves, and reduced the time they spent feeding on trees in favor of more time feeding on figs and palms.

Pileated Gibbon Density in Relation to Habitat Characteristics and Post-logging Forest Recovery
Rungnapa Phoonjampa
Read it because... Pileated gibbon densities depend on mature and undisturbed evergreen forest. Gibbons can persist in disturbed areas if the forest is protected, but recovery to previous densities may take decades. The authors suggest that this is due to the slow pace of forest regeneration and/or poor recovery potential of gibbons.

The Abundance of Large Ateline Monkeys is Positively Associated with the Diversity of Plants Regenerating in Neotropical Forests
Pablo R. Stevenson
Read it because... This study demonstrates the importance of large Neotropical primates in seed dispersal processes by showing that a low abundance, or absence, of these primates is associated with lower diversity of plants in the regeneration phase.

The Long-term Impact of Timber Harvesting on the Resource Base of Chimpanzees in Kibale National Park, Uganda
Kevin B. Potts
Read it because... Commercial logging is often considered incompatible with the survival of forest-dwelling primates. The author demonstrates that although logging operations in the 1960s in Kibale National Park, Uganda removed important dietary species for chimpanzees, critical subsistence resources were largely unaffected. The density of chimpanzees at logged sites in Kibale has remained stable over time.

Low Primate Diversity and Abundance in Northern Amazonia and its Implications for Conservation
Antonio Rossano Mendes Pontes
Read it because... Large areas of the Rio Negro basin in Amazonia are covered by continuous tracts of tropical forest, which seem suitable for primate species, but are virtually empty. The author suggests understanding this has important implications for the design of conservation reserves.

Dynamics in Hurricane Prone Forests

Published: September 2012

This virtual issue compiles studies from around the world on cyclone impacts on forests and their species to provide insights about the vulnerability and potential recovery of these forests. We would do well to understand forest vulnerability to, and recovery from, cyclones. This is particularly because some commentators perceive increasing frequency and severity of tropical storms as a direct result of climate change, although others are more circumspect. Forests also now have to cope not only with natural disturbances, to which they are often well adapted, but also to habitat fragmentation, invasive species and fires, all of which interact with natural disturbances and lead to a very uncertain forest future.
