Dispersal, pair formation and social structure in gibbons (Hylobates lar)
- W. Brockelman, U. Reichard, U. Treesucon, J. Raemaekers
- Behavioral Ecology and Sociobiology
- 8 May 1998
Observations on reproduction, natal dispersal, pair formation, and group structure based on longitudinal observations of several white-handed gibbon groups spanning 18 years are at odds with the traditional view that gibbons live in nuclear family groups consisting of a pair of adults and their offspring.

Averting biodiversity collapse in tropical forest protected areas
These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines. Expand
Estimation of density of gibbon groups by use of loud songs
The density of gibbon populations may be estimated by listening for the loud duetted songs of monogamous territorial groups. This method requires a correction factor which must be estimated from the… Expand
Competition, the Fitness of Offspring, and Optimal Clutch Size
- W. Brockelman
- The American Naturalist
- 1 November 1975
The theory thus explains how natural selection on individual parents can lead to population control through regulation of birth rates and behavioral mechanisms which seem to prevent overcrowding and starvation. Expand
CTFS-ForestGEO: a worldwide network monitoring forests in an era of global change.
- K. Anderson-Teixeira, S. Davies, +105 authors J. Zimmerman
- Business, Environmental Science
- Global change biology
- 1 February 2015
The broad suite of measurements made at CTFS-ForestGEO sites makes it possible to investigate the complex ways in which global change is impacting forest dynamics, and continued monitoring will provide vital contributions to understanding worldwide forest diversity and dynamics in an era of global change.

Field studies on the transmission of the human liver fluke, Opisthorchis viverrini, in northeast Thailand: population changes of the snail intermediate host.
- W. Brockelman, E. S. Upatham, V. Viyanant, S. Ardsungnoen, R. Chantanawat
- Biology, Medicine
- International journal for parasitology
- 1 October 1986
Control of opisthorchiasis through snail control does not appear practical because of the widespread distribution of the snails, their ability to survive in very unstable habitats, and for other reasons concerned with the existence of the fish host between snail and human hosts. Expand
Functional differences within a guild of tropical mammalian frugivores.
This work compared the influence of three seed-dispersing tropical mammals, lar gibbons, sambar deer, and red muntjac deer, on the demography of a shared host tree in Thailand, Choerospondias axillaris. Expand
Bushmeat poaching reduces the seed dispersal and population growth rate of a mammal-dispersed tree.
- J. Brodie, O. Helmy, W. Brockelman, J. Maron
- Biology, Medicine
- Ecological applications : a publication of the…
- 1 June 2009
How variation in hunting pressure across four national parks with seasonal forest in northern Thailand influenced the relative abundance of gibbons, muntjac deer, and sambar deer and how variation in disperser numbers affected C. axillaris seed dispersal and seedling abundance is quantified. Expand
Nonredundancy in the dispersal network of a generalist tropical forest tree.
The results underscore the need for research on broader spatial and temporal scales, which combines studies of dispersal and plant recruitment, to better understand mechanisms that maintain network stability. Expand
An Analysis of Density Effects and Predation in Bufo Americanus Tadpoles
- W. Brockelman
- 1 July 1969
The effects of density on growth and survivorship of Bufo americanus tadpoles and the importance of some predators were investigated experimentally in two small ponds in southeastern Michigan.… Expand
