Elevational gradients in ant species richness: area, geometry, and Rapoport’s rule
Studying the distributions of plants and animals along environmental gradients can illuminate the factors governing and maintaining species diversity. There are two general predictions of how species richness and elevation are related: either species richness decreases monotonically with increasing elevation or richness peaks at mid-elevations. Several processes might contribute to this pattern...
متن کاملStrong seasonality and clear choice of resting plant in a Neotropical harvestman (Arachnida: Opiliones)
Preliminary observations suggested that the Neotropical harvestman Jussara sp. (Sclerosomatidae, Eupnoi) had a patchy distribution and a marked seasonality, comparable to species in the Northern hemisphere. This would be an unusual pattern, since conditions of temperature and humidity are very different between tropical and temperate environments. Using a mark-recapture method, we investigated ...
متن کاملChemical and behavioral defenses of the neotropical harvestman Camarana flavipalpi (Arachnida: Opiliones)
The defensive secretion of the harvestman Camarana flavipalpi (Gonyleptidae) was chemically characterized, revealing the presence of a single, highly volatile component (2-methyl-5-ethyl-phenol). Individuals do not frequently use chemical defenses and rely mainly on thanatosis as defense. Two types of emission of secretions were recorded: a globule at the gland opening without liquid displaceme...

Type specimens of Caddo dentipalpis (Koch & Berendt, 1854), Dicranopalpus ramiger (Koch & Berendt, 1854), Nemastoma (?) incertum Koch & Berendt, 1854, Mitostoma (?) denticulatum (Koch & Berendt, 1854) and Histricostoma (?) tubercula...
متن کاملReproductive biology of the neotropical harvestman (Goniosoma longipes) (Arachnida, Opiliones: Gonyleptidae): mating and oviposition behaviour, brood mortality, and parental care
Goniosoma longipes is a neotropical cavernicolous harvestman that exhibits parental care. Reproductive activity in G. longipes is more intense during the wet season. Mating lasts up to 3 min, and the whole oviposition process may take over 5 h. During oviposition the female may be reinseminated once or twice by the mating male. Females oviposit 60±210 eggs on the cave wall and guard egg batches...
