Utilization of mixed species through grouping and standards

Australian Forestry, 1980
Summary The main thrust of forest products research on the world scene in recent years has been directed towards improving the potential of those economies dependent upon the marketing of mixed timber species. Usually the need is greatest in the tropical and sub-tropical regions.

Benefits to satellite members in mixed-species foraging groups: an experimental analysis

Animal Behaviour, 1998
Hypotheses proposed to explain the formation of mixed-species foraging groups have focused on both foraging and antipredation benefits. Mixed-species flocks of bark-foraging birds form during the winter in the eastern deciduous forests of North America.

Anti-Predation Benefits in a Mixed-Species Group of Amazonian Tamarins

Folia Primatologica, 1993
Because of their small body size, tamarins are potentially vulnerable to a wide range of predator species. This paper examines the general patterns of predator avoidance of the Avila-Pires saddle-back tamarin (Saguinus fuscicollis avilapiresi) and the red-cap moustached tamarin (Saguinus mystax pileatus) in the upper Urucu river, Amazonas, Brazil.

Do black colobus in mixed-species groups benefit from increased foraging efficiency?

Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 1997
Seed-eating in the African colobines varies according to species and site. Because seeds are more palatable than leaves, seed-eating is considered to result from a positive choice by colobines. A year-long study of the diet of Colobus satanas in Central Gabon confirmed that this species eats a significant amount of seeds.

Mixed-species primate groups in the kibale forest: Ecological constraints on association

International Journal of Primatology, 1996
Five species of diurnal primates in the Kibale Forest of western Uganda— red colobus (Colobus badius),black- and- white colobus (Colobus guereza),redtail monkeys (Cercopithecus ascanius),blue monkeys (Cercopithecus mitis),mangabeys (Cercocebus albigena)-often associate in mixed- species groups that vary in size and composition from day to day.

Mixed-species grouping in Thomson's and Grant's gazelles: the antipredator benefits

Animal Behaviour, 1990
Abstract Thomson's gazelles, Gazella thomsoni , and Grant's gazelles, G. granti , in the Serengeti National Park, Tanzania, frequently associate in mixed-species groups. Males are more likely to associate than females. Here the antipredator benefits of such associations are investigated.

Spacing behavior of visual- and tactile-feeding shorebirds in mixed-species groups

Canadian Journal of Zoology, 1989
Time activity budgets were determined for tactile-feeding Long-billed Dowitchers (Limnodromus scolopaceus) and Pectoral Sandpipers (Calidris melanotus), and for visual-feeding Lesser Yellowlegs (Tringa flavipes) and Semipalmated Sandpipers (Calidris pusilla) while these species were foraging in mixed-species groups at Inuvik, Northwest Territories ...

Ranging Patterns of Callimico goeldii (callimico) in a Mixed Species Group

2009
Ranging patterns are behavioral adaptations that relate to demographic and ecological variables, such as population density and resource distribution. Intraspecific variation in ranging may reflect responses to variable environmental conditions. A study of Callimico goeldii, the callimico or Goeldi’s monkey, in association with Saguinus fuscicollis ...

Consequences of Joint-Territoriality in a Mixed-Species Group of Tamarin Monkeys

Behaviour, 1992
AbstractGroups of saddle-back (Saguinus fuscicollis) as moustached tamarins (Saguinus mystax) in a western Amazonian forest jointly defended home ranges larger than 100 ha, which were held in common throughout the year. Resources were defended by direct exploitation in extensive areas shared with other groups, or through intensive and frequent ...
