Download or read book The Neotropical Goblin Spiders of the New Genera Ponsoonops and Bipoonops Araneae Oonopidae written by Angelo Bolzern and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two new genera, Ponsoonops and Bipoonops, are established for groups of species characterized by sexually dimorphic dorsal abdominal scutum expression (with a scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. Both genera belong therefore to the Varioonops complex, represented now by three described Neotropical genera. Members of Ponsoonops are united by three putative synapomorphies in males: a "pierlike" dorsal scutum completely fused to the epigastric scutum, a patch of short setae ventrodistally on metatarsi I and II, and a short anteromedian protrusion on the endites. Female Ponsoonops specimens differ from other members of the Varioonops complex in having small lateral sclerites at the epigynal area and a smooth sternum. Members of Bipoonops share a large, irregularly shaped, rather indistinct dark spot posteriorly on the carapace, a putative synapomorphy, and a moderately rugose sternum surface; males are characterized by a distinct, bipartite conductor. A total of 22 Ponsoonops species, 21 new to science, are described: P. duenas, P. hamus, and P. tacana from Mexico, Guatemala, and Belize, P. bilzi, P. lucha, P. samadam, P. sanvito, and P. viejo from Costa Rica, P. bollo, P. boquete, P. coiba, P. fanselix, P. frio, P. lerida, P. mirante, P. panto, P. salimsa, and P. vuena from Panama, P. pansedro from Colombia, P. micans (Simon, transferred from Dysderoides) from Venezuela, P. yumuri from Cuba, and P. lavega from the Dominican Republic. Bipoonops is described for three new species found on the western slope of the Andes in Ecuador: B. baobab, B. pucuna, and B. tsachila.

Download or read book The Andean Cloud Forest written by Randall W. Myster and published by Springer Nature. This book was released on 2020-11-12 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book focused solely on Andean Cloud Forests (ACF) has never been published. ACF are high biodiversity ecosystems in the Neotropics with a large proportion of endemic species, and are important for the hydrology of entire regions. They provide water for large parts of the Amazon basin, for example. Here I take advantage of my many years working in ACF in Ecuador, to edit this book that contains the following sections: (1) ACF over space and time, (2) Hydrology, (3) Light and the Carbon cycle, (4) Soil, litter, fungi and nutrient cycling, (5) Plants, (6) Animals, and (7) Human impacts and management. Under this premise, international experts contributed chapters that consist of reviews of what is known about their topic, of what research they have done, and of what needs to be done in the future. This work is suitable for graduate students, professors, scientists, and researcher-oriented managers.
