Around forty bird species habitually reproduce in the Northern Hemisphere during summer, and migrate to the Southern Hemisphere during northern winter. These migrating birds fly together in large or small groups until they have reached the Caribbean, Central American, or Brazilian shores. Charadrius semipalmatus, Bonaparte 1825, is one of these migrating species that uses resting and feeding areas along eastern and western coasts of North and South America, with several records for the Brazilian coast, and very few for the inland country.

Abstract:
Two new pseudoscorpion species of the genus Pseudochthonius Balzan, 1892 are described from caves in the Lagoa Santa karst area in Southeast Brazil. Pseudochthonius limettioides sp. nov. was collected in ten caves and is a troglobite that lacks eyes and body pigmentation. Pseudochthonius lundi sp. nov. was collected in three caves and is considered a troglophile with only one pair of eyes. Both species might be threatened by mining projects and more studies are needed to better understand many aspects of their biology.

Abstract:
Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability of roosts are important aspects of their ecology. Karst areas have great potential for the availability of day roosts, since they form caves, which serve as bat shelters. Here we characterize the caves used by bats in a preserved karst area of Southeastern Brazil. Using logistic regression analysis we identified the cave characteristics that influence bat occupation. Sixty-six caves were characterized based on measurements of internal height and width, height and width of the entrance(s) of the
