This massive compendium on the influence of climatic variables on insect abundance works from the principle that even when the existence of an insect depends on conditions other than climatic (e.g., presence of its food plant), climate “remains as a definite, if not dominant, factor,” a ...
We found that our validation metrics improved considerably after removing samples collected in anthropic disturbed habitats, suggesting that an-thropic disturbance is the principal factor defining taxon occurrences. Besides our results showing similarities with previous studies, they also showed a significant...
Extreme humidities were unfavorable, with low relative humidity often being an important controlling factor. In the summer, femaleslived 1–3 weeks and males less than 1 week, while in the winter females lived up to 2 months. The number of eggs per female approached 100, except in Egypt ...
length/weight ratio, condition factor, and cephalic index indicate that the three populations presented normal development. stomachs were classified according to the degree of repletion. differences in repletion were attributable to the feeding behaviour of the different species. the relative abundance ...
Grazing effects on juveniles can be a more important factor affecting brachiopods than carnivorous predation on adults because juveniles are rarely found alive on exposed surfaces, size of adults is not lower on exposed surfaces than in crevices, predators in this area do not prefe...
The analysis uses a weight-of-evidence approach based on the percent of the community associated with a matrix factor. We have used the autecology matrix to examine historical fish community data from the Dahan River, Taiwan. The results show that the method provides an improved understanding of...
