Sobral-Souza, Thadeu; Stropp, Juliana; Santos, Jessie Pereira; Prasniewski, Victor Mateus; Szinwelski, Neucir; Vilela, BrunoMade available in DSpace on 2022-05-01T05:29:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-06-25; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Background. A key challenge for conservation biology in the Neotropics is to understand how deforestation affects biodiversity at various levels of landscape fragmen...
Complex mating behavior in Adelosgryllus rubricephalus (Orthoptera, Phalangopsi...
Zefa, Edison; Martins, Luciano de P.; Szinwelski, NeucirDescrevemos o comportamento reprodutivo de Adelosgryllus rubricephalus Mesa & Zefa, 2004. Em observações realizadas em laboratório verificamos a seguinte seqüência no comportamento de acasalamento: (1) reconhecimento sexual por antenação; (2) corte, em que o macho volta seu abdômen em direção à fêmea, vibra as antenas médio-lateralmente, treme o corpo ântero-posteriormente e estridula intermitentemente, enquant...
Proventriculus of three nemobiinae crickets (Orthoptera: Grylloidea: Trigonidii...
Serrao, Jose Eduardo; Sperber, Carlos Frankl; Szinwelski, Neucir; Rodrigues, Moreno S.; Pereira, Marcelo RibeiroThe morphology of the proventriculus may supply useful taxonomic characters for some species of crickets. This study evaluated if the proventriculus can be used to distinguish three species of Nemobiinae crickets: Phoremia sp. n., Zucchiella sp. n., and Amanayara sp n. In crickets the proventriculus presents six lobes, each one bearing eight appendices along its longitudinal axis. In Phoremia sp. n., the centra...
Forest litter crickets prefer higher substrate moisture for oviposition: Eviden...
Farias-Martins, Fernando de; Sperber, Carlos Frankl; Albeny-Simões, Daniel; Breaux, Jennifer Ann; Fianco, Marcos; Szinwelski, NeucirFor insects, choosing a favorable oviposition site is a type of parental care, as far as it increases the fitness of its offspring. Niche theory predicts that crickets should show a bell-shaped oviposition response to substrate moisture. However, lab experiments with mole crickets showed a linear oviposition response to substrate moisture. Studies with the house cricket Acheta domesticus also showed a linear ju...
Aggregation of cricket activity in response to resource addition increases loca...
Solar, Ricardo Ribeiro de Castro; Sperber, Carlos Frankl; Rosa, Cassiano Sousa; Szinwelski, NeucirCrickets are often found feeding on fallen fruits among forest litter. Fruits and other sugar-rich resources are not homogeneously distributed, nor are they always available. We therefore expect that crickets dwelling in forest litter have a limited supply of sugar-rich resource, and will perceive this and displace towards resource-supplemented sites. Here we evaluate how sugar availability affects cricket spec...
Diversidade de grilos (Orthoptera: Grylloidea): Aspectos ecológicos e o metodol...
Szinwelski, NeucirConselho Nacional de Desenvolvimento Científico e Tecnológico; A teoria ecológica propõe uma série de mecanismos que podem afetar a diversidade. Dentre tantas possibilidades, o objetivo central dessa tese foi investigar a resposta da riqueza de espécies de grilos ao tempo de regeneração florestal e a disponibilidade de recursos. No primeiro capítulo dessa tese, testou-se a resposta da riqueza espécies e composi...
Riqueza de espécies de grilos (Orthoptera: Grylloidea) em fragmentos de Mata At...
Szinwelski, NeucirConselho Nacional de Desenvolvimento Científico e Tecnológico; With an increasing time of forest regeneration has an increase in diversity of resources and changes in environmental conditions, leaving the more stable environment. These factors, along with the structure and complexity of habitat, spatial and historical processes, interactions intraspecific and interspecific, among others, are essential for the d...
