In neotropical regions, fossil bat guano accumulated over time as laminated layers in caves, hence providing a high-resolution temporal record of terrestrial environmental changes. Additionally, cave settings have the property to preserve such organic sediments from processes triggered by winds (deflation, abrasion and sandblasting) and intense rainfall (leaching away). This study reports both stable carbon and nitrogen isotope compositions of frugivorous bat guano deposited in a well-preserved stratigraphic succession of Blanchard Cave on Marie-Galante, Guadeloupe. These isotopic data are discussed with regard to climate changes and its specific impact on Eastern Caribbean vegetation during the Late Pleistocene from 40 to 10 ka cal. BP. Guano delta C-13... |

From 1986 to 1992, I surveyed the invertebrate fauna of twelve limestone caves from South Ribeira Valley (State of Paraná, Brazil). Associated to walls in the entrace zone live Enoploctenus and Blechroscelis spiders, Goniosoma opilionids, Strinalia crickets, Latebraria amphipyroides moths, and Culicidae and Sciaridae dipterans. In aphotic zone, occur Plato spiders, Daguerreia inermis opilionids, Pseudonannolene strinatii diplopods, Smicridea caddisflies and the aquatic crustacean Aegla paulensis. I found in both zones Ctenus fasciatus spiders. Paronella collembolans, Zelurus travassosi heteropterans, Cholevidae and Anthribidae beetles, Phoridae dipterans and Braconidae wasps. One of the most important energy sources in these caves is the hematophagous bat... |
