Thermal constraints on foraging of tropical canopy ants

Oecologia, 2017
Small cursorial ectotherms risk overheating when foraging in the tropical forest canopy, where the surfaces of unshaded tree branches commonly exceed 50 °C. We quantified the heating and subsequent cooling rates of 11 common canopy ant species from Panama and tested the hypothesis that ant workers stop foraging at temperatures consistent with the ...

FORAGE CONSERVATION IN THE TROPICS*

Grass and Forage Science, 1969
Under arid tropical conditions the natural grazing provides less than maintenance requirements for 8–9 months of the year. Conservation of natural or sown herbage, either as hay or silage, should be discouraged because of the low nutritive value of the product, and the unfavourable weather usually prevailing during conservation.

POTENTIAL OF FORAGE PEANUT IN THE TROPICS

1997
Two of the most important perennial forage species of the genus Arachis (A. glabrata Benth . and A. pintoj Krap. & Greg) have been evaluated by TARS in preliminary trials. Desirable qualities of these forage legumes are (1) high biomass of excellent quality, (2) insect resistance and low disease susceptibility, (3) drought tolerance, and (4) long ...

Foraging for Insects by a Tropical Hummingbird

The Condor, 1971
Evolutionary-ecological studies of tropical plants and animals have illustrated that certain tropical organisms respond to differences between wet and dry seasons. Certain species of trees show distinct flowering and fruiting patterns in relation to the dry season in various regions of Costa Rica (Janzen 1967).
