Benefits of ant attendance for aphid colonies of varying density

Benefits between species engaged in mutualistic interactions are often dependent on ecological context. For instance, in mutualisms in which aphids exchange food for ant protection from predators, the degree of benefit that aphids receive from ants depends on the presence of other arthropod predator

Assessing the impacts of long-term pan trapping on native bee populations in sub-alpine ecosystems

Pollination by native bees is an essential ecosystem service in both natural and agricultural systems. During the last several decades, there have been reported declines in native bee populations worldwide. Due to recent declines, there is an increasing need for standardized population monitoring pr

Patterns of sap-foraging on willows (<i>Salix spp.i</i>) by a keystone species: the Red-naped Sapsucker (<i>Sphyrapicus nuchalis</i>)

The Red-naped Sapsucker (Sphyrapicus nuchalis) is a keystone species in montane/subalpine ecosystems of the Rocky Mountains of Colorado. By excavating nest cavities in aspen trees and sap wells in willow shrubs, sapsuckers indirectly provide nest holes and food, respectively, to many other species.

Functional importance of plumage badges as intraspecific signals in White-crowned sparrows (<i>Zonotrichia leucophrys oriantha</i>).

Status badges, such as bird plumage colors, are important parts of animal communication; they mediate intra- as well as intersexual interactions. Reliability of avian plumage badges is thought to be maintained by selective pressures, including social punishment. Costs, benefits, and resultant fitnes
