1. Resposta Adaptativa de Melipona subnitida Ducke e a Termorregulação Colonial em Diferentes Condições Térmicas no Contexto das Mudanças Climáticas
Resumo Efeitos negativos decorrentes do aquecimento do sistema climático têm sido relatados para diferentes espécies de abelha. Dada a importância econômica, social e ambiental das abelhas, particularmente, para o bioma Caatinga, necessário se faz conhecer potenciais efeitos negativos a fim de orientar medidas eficientes de adaptação desses animais f

2. Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate
RESUMO A polinização é um fator essencial na produção agrícola mundial e existe a necessidade de aumentar o número de espécies de abelhas que podem ser criadas para a polinização na agricultura, como a abelha solitária coletora de óleo Centris (Heterocentris) analis (Fabricius, 1804). Aqui, os comportamentos de nidificação e reprodutivo dessa a

3. Do euglossine females reside in a single nest? Notes on Euglossa cordata (Hymenoptera: Apidae: Euglossini)
RESUMO Abelhas Euglossa Latreille, 1802 não vivem em grandes colônias, e estas geralmente são mantidas ou “reativadas” por novas fêmeas, subordinadas à mãe, que constroem e fornecem células de cria. Este estudo teve como objetivo obter informações sobre o tempo que as abelhas levam para prover novas células, sobre a emergência e permanência d

4. Orchid bees (Hymenoptera, Apidae, Euglossini) are seasonal in Seasonal Semideciduous Forest fragments, southern Brazil
Abstract Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry seasons, where climatic variables are regarded to be good predictors of populational patterns. The m

5. Phylogeny of the Augochlora clade with the description of four new species (Hymenoptera, Apoidea)
ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social,

7. Reproductive aspects of the Purple-throated Euphonia, Euphonia chlorotica (Aves: Fringillidae) in southeastern Brazil, and first record of the species nesting inside a vespiary
ABSTRACT Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and 2012. Nests were globular with a lateral entrance, and measured 97.9 ± 14.4 mm in outside heigh

8. 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

9. Reproductive behavior of the Red-crested Finch Coryphospingus cucullatus (Aves: Thraupidae) in southeastern Brazil
ABSTRACT Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests. This information may be valuable to elucidate the phylogenetic relationships of this bird, and to design plans to manage it. Nesting activities occurred from October to

10. Behavior of Layers under Different Light Sources
ABSTRACT Light is an important factor in the management of laying poultry. The ideal lamp spectrum that provides the best welfare conditions still needs to be determined. Wavelength and light intensity influence poultry behavior and their welfare. This study evaluated the influence of four lamps types with different light spectra on the behavior of seventy 5

11. Development and Performance of a Mechanical Egg Collection System Versus the Hand-Operated Dutch Nest
ABSTRACT The aim of this study was to design a new mechanical nesting system based on scientific works on the behavior of laying hens, and to compare its performance with that of a hand-operated Dutch nest. The equipment was assessed in two poultry houses; in the first one, the eggs were collected manually, whereas in the second one, the newly designed mecha

12. Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga
Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga. Colonies of the wasp Mischocyttarus cassununga (von Ihering, 1903) are easily found in urban areas. However, in spite of the massive presence of this species in cities, little is known about its nesting habits, colony success and productivity. The present study aimed at
