1. What do we know about Neotropical trap-nesting bees? Synopsis about their nest biology and taxonomy
Abstract Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pol

2. Nesting biology of three Megachile (Hymenoptera: Megachilidae) species from Eastern Amazonia, Brazil
Abstract Megachile Latreille is a conspicuous genus of solitary bees distributed worldwide. However, the biology of tropical species is still little known. We present data on biology of Megachile brasiliensis Data Torre, Megachile sejuncta Cockerell and Megachile stilbonotaspis Moure found in two remnants of eastern Amazonian forest in northeastern Brazil.

3. Breeding biology of Tyrannus melancholicus (Aves: Tyrannidae) in a restinga reserve of southeastern Brazil
ABSTRACT Existing knowledge of the breeding success and life history characteristics of most Neotropical bird species is scarce. Here, we help fill this gap by analyzing aspects of the breeding biology of the Tropical Kingbird Tyrannus melancholicus (Vieillot, 1819), which is a good model for this kind of study as it is a common species occurring in various

4. The breeding biology and nest success of the Short-tailed Antthrush Chamaeza campanisona (Aves: Formicariidae) in the Atlantic rainforest of northeastern Brazil
ABSTRACT We present the results of a 26-year study on the breeding biology of the Short-tailed Antthrush, Chamaeza campanisona (Lichtenstein, 1823) in an Atlantic rainforest remnant of northeastern Brazil (Alagoas/Pernambuco). We followed the fate of 38 nests, of which 19 failed, 11 succeeded and 8 had an unknown fate. The presence of most nests coincided wi

5. A new technique in the excavation of ground-nest bee burrows (Hymenoptera: Apoidea)
ABSTRACT Bees have a diversified natural history, thus the methods applied to study such diversity are varied. When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied since researchers started using trap-nests. However, bees whose nests are built underground are poorly studied due to the difficu

6. The breeding biology, nest success, habitat and behavior of the endangered Saffron-cowled Blackbird, Xanthopsar flavus (Aves: Icteridae), at an Important Bird Area (IBA) in Rio Grande do Sul, Brazil
ABSTRACT The Saffron-cowled Blackbird, Xanthopsar flavus (Gmelin, 1788), is a globally vulnerable icterid endemic to grasslands and open areas, and a priority species for research and conservation programs. This contribution provides information on the population size, habitat, behavior, breeding biology and nest success of X. flavus in two conservation unit

7. Biology of a trap-nesting wasp of one species the ground-nesting Liris (Hymenoptera: Crabronidae) from the Atlantic Forest of southern Brazil
ABSTRACT Studies on the nesting biology of Liris are restricted to a few notes and observations on ground-nesting species. There are no studies of this kind about Brazilian species. We investigated and described the nesting biology of Liris sp. obtained by trap-nests that were installed at an area of Atlantic Forest vegetation (25°10'S, 48°18'W) in souther

8. On the nesting biology of eumenine wasps yet again: Minixi brasilianum (de Saussure) is a builder and a renter... at the same time! (Hymenoptera, Vespidae, Eumeninae)
Our understanding of eumenine nesting biology is still elusive. The use of two nesting strategies, namely renting and building, are reported concomitantly for the first time for Minixi brasilianum (de Saussure, 1875). Ecological factors such as resource availability and protection against potential enemies may play an important role in eumenine nesting biolo

9. On the nesting biology of Pirhosigma Giordani Soika (Hymenoptera, Vespidae, Eumeninae), with special reference to the use of vegetable matter
On the nesting biology of Pirhosigma Giordani Soika (Hymenoptera, Vespidae, Eumeninae), with special reference to the use of vegetable matter. The use of vegetable matter in nest building is not widespread among the Eumeninae, and is reported for the first time for the two species of potter wasps Pirhosigma superficiale and P. limpidum. These wasps make most

10. Biologia de nidificação, sazonalidade e inimigos naturais de Epicharis (Epicharoides) picta (Smith, 1874) (Apidae: Centridini) no município de Viçosa, MG Brasil / Nesting biology, seasonality and natural enemies of Epicharis (Epicharoides) picta (Smith, 1874) (Apidae: Centridini) in Viçosa, MG Brazil
As abelhas constituem o principal grupo de polinizadores na maioria dos ecossistemas terrestres. Acredita-se que e existam mais de 20.000 espécies de abelhas no mundo. Dessas, cerca de 80% são solitárias, 15 % possuem hábito parasítico e cerca de 5% são sociais. Um grupo interessante de abelhas solitárias é o conhecido como abelhas coletoras de óleo

11. Nidificação de abelhas e vespas solitárias e biologia reprodutiva de Megachile dentipes Vachal (Hymenoptera, Megachilidae) em ninhos-armadilha
Terrestrial ecosystems, solitary bees and wasps play important roles as pollinators, predators and parasites. Most part of the life of these Hymenoptera is designed to aspects related to nesting, including the search of the nest site, nest construction and food collection to rear the larvae. However, in natural environments the nests of these insects are dif

12. Estrutura populacional e variabilidade genética de tartaruga verde (Chelonia mydas) da região de Cananéia, São Paulo / Populational structure and genetic variability of green sea turtle (Chelonia mydas) from Cananéia, São Paulo
The green turtle, Chelonia mydas, is an endangered marine reptile that nests and forages along the Brazilian coast and oceanic islands, among other tropical areas. Due to the highly migratory and oceanic nature of these animals, ecological studies are many times difficult to carry out, and many questions about their biology remain. Molecular genetic analysis
