Uso de químicos no reconhecimento sexual de opiliões (Arachnida: Opiliones)"
(Universidade Federal de São Paulo, 2015-07-30)
Several arthropod species use chemicals to detect sexual partners. In harvestmen (Arachnida, Opiliones) there are evidences that chemicals have an important role in intra-specific communication. Using the behavior of ...
Ilhas de floresta nas alturas: inferindo processos históricos associados às distribuições de aves montanas da Mata Atlântica
(Universidade Federal de São Paulo, 2015-07-31)
The mountains of the Brazilian Atlantic Forest have a high degree of endemism and its biogeographical history is poorly explored. One hypothesis for the diversification of montane organisms, related to the refuge theory, ...
Morfologia comparada da cabeça de Pentatomidae (Hemiptera: Heteroptera)
(Universidade Federal de São Paulo, 2015-07-29)
The heteropteran head presents a high specialization level, making this group known for having, among other features, their piercing and sucking mouthparts in the anterior part of the head. Pentatomidae is the forth most ...
Variação geográfica no tamanho corporal e dimorfismo sexual de tamanho em uma espécie de besouro predador de sementes de Leucaena leucocephala
(Universidade Federal de São Paulo, 2015-07-31)
A central question in ecology and evolutionary biology is to explain large-scale spatial patterns of variation in body size. Explaining these patterns is important because larger individuals may show advantages in fitness ...
Diversidade de heterópteros terrestres (Insecta: Hemiptera: Heteroptera) na Serra do Japi, Sudeste do Brasil
(Universidade Federal de São Paulo, 2015-12-18)
It is estimated that in Brazil there are between 4,000 and 6,000 species of Heteroptera, however, knowledge about the regional fauna is still limited. For the state of São Paulo, the knowledge of the fauna of Heteroptera ...
História natural e mecanismos utilizados na navegação no opilião Heteromitobates discolor (Arachnida,Opiliones)
(Universidade Federal de São Paulo, 2015-07-27)
Animals may use external or internal cues to navigate towards an original location. Here we studied the homing ability of the harvestman Heteromitobates discolor (Arachnida, Opiliones). We tested the importance of (1) their ...
O papel da modulação autonômica nos ajustes de temperatura em teiús (Salvator merianae)
(Universidade Federal de São Paulo, 2015-10-29)
There is evidence that in reptiles there is the ability to regulate the rate of heat exchange between the body and the means adjusting the peripheral blood flow and for this by increasing or decreasing the heart rate. This ...
Comportamento termorregulatório e alimentação em Iguana iguana (Squamata, Iguanidae)
(Universidade Federal de São Paulo, 2015-06-30)
Few environmental factors exert so much influence on the physiology of animals as temperature. Each activity carried out by an animal occurs in a range of body temperatures that is physiologically appropriate. Some reptiles ...
Efeito da heterogeneidade da paisagem sobre redes de interações plantas-polinizadores
(Universidade Federal de São Paulo, 2015-07-30)
Most studies about the effects of anthropogenic landscape changes on biodiversity have focused on parameters such as species richness and abundance. Few are those that aim to understand the effects of these disturbances ...
Termorregulação e desempenho fisiológico de Thorapa taophora (Anura: Cycloramphidae)
(Universidade Federal de São Paulo, 2015-07-31)
Ectotherms must regulate body tempetarute inside a tolerable range of temperature to optmize physiological functions. In this context, behavioural thermoregulation is an important strategy for metabolic compensation. Shifts ...
