The ecology of restoration: historical links, emerging issues and unexplored realms
Ecology may inform current restoration practice, but there is considerable room for greater integration between academic scientists and restoration practitioners, especially on the effects of contingency.
Ecological models of female social relationships in primates: similarities, disparities, and some directions for future clarity
Several models have been proposed to explain the variation that exists in female social relationships among diurnal primate species. While there are similarities among them, notably in the ecological…
Ants on swollen-thorn acacias: species coexistence in a simple system
On the black cotton soils of the Laikipia ecosystem in Kenya, two swollen-thorn acacia species support nine ant species, four of which are apparently obligate plant-ants, which are examples of coexisting diversity on an apparently uniform resource.
Long-Term Glades in Acacia Bushland and Their Edge Effects in Laikipia, Kenya
Working in central Laikipia, this study documented differences in vegetation, animal use, and soils at four of these glades, and at increasing distances from glade edges, which increases ecosystem heterogeneity and resource use by domestic and wild animals.
Synergy of multiple partners, including freeloaders, increases host fitness in a multispecies mutualism

It is shown that tree fitness is enhanced by partnering sequentially with sets of different ant symbionts over the ontogeny of a tree, and lifespan inequalities among mutualists may help cooperation persist in the face of exploitation.
Movements of vervets (Cercopithecus aethiops) and patas monkeys (Erythrocebus patas) as estimators of food resource size, density, and distribution

Compared to patas, vervets travelled shorter distances, moved shorter distances between food sites, stopped less often, and had longer feeding bouts, suggesting that foods of verveTS are denser and larger, overall, than foods of patas.

The results show that large mammals maintain cooperation within a widespread symbiosis and suggest complex cascading effects of megafaunal extinction.

Natural Die‐Offs of Large Mammals: Implications for Conservation
- T. Young
- 1 June 1994
The viability of populations is a central concern of biological conservation. The occurrence of catastrophic die-offs may greatly reduce the long-term viability of populations. Theoretical extinction…
