ABSTRACT Community structure, macrohabitat selection, and patterns of species co-occurrence were examined during a 14-month study small mammals in the Cerrado Province central Brazil. Data collected from mark-recapture grids brejo gallery forest, live-trapping specimen collection all habitat types within cerrado (campo limpo, campo sujo, [s.s.], cerradão, brejo, valley-side wet campo, forest). Gallery forest supported highest richness, most complex vertical distribution species, level...
Differences in chemical and nutritional traits among leaves of different ages from plants habitats are expected to influence patterns herbivore foraging damage. Variability the extent insect herbivory on understory tree Pentagonia donnell-smithii (Rubiaceae) was quantified with respect leaf age habitat type (sites) lowland tropical wet forest Costa Rica. Rates were higher for young than mature leaves. The common beetle, Phanaeta sp. (prob. ruficollis, Chrysomelidae) preferred leaves, but...
Contemporary climate change is modifying the distribution, morphology, phenology, physiology, evolution, and interspecific interactions of species. Effects are mediated not only through magnitude experienced (exposure) an animal's sensitivity to such changes, but also ability population or species adjust climatic variability genetically, behaviorally, spatially (via its distribution) (i.e., adaptive capacity; AC). Here, we used attribute-based framework systematically evaluate compare AC...
Interactions between genotype and environment determine the underlying constitutive (background—level) resistance of individual plants to herbivory. Resistance, however, may change in response herbivory (induced resistance). This study was designed investigate temporal fluctuations resistance, test relative influences browsing—induced on patterns mammalian A natural population creosotebush, Larrea tridentata, browsed by black—tailed jackrabbits, Lepus californicus, served as system....
Herbivory is an important ecological process in forest canopies but difficult to measure, especially for whole stands. We used the Wind River Canopy Crane Washington State access 101 randomly-located sample points throughout canopy. This provided a relatively quick and convenient way estimate herbivory stand. The overall level of was estimated at 1.6% leaf area. distribution strongly skewed lower canopy where broad-leafed species experienced higher levels herbivory. averaged 0.3% conifers...
