Machado, Marina [UNESP]; Salti, Fernanda Cristina [UNESP]; Bertini, Giovana [UNESP]; Zara, Fernando José [UNESP]Made available in DSpace on 2022-04-29T08:31:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-07-01; We evaluated the mating behavior of Potimirim potimirim in the laboratory based on the assumption that this caridean might be hermaphroditic. We also performed histology and scanning electron microscopy analyses of the reproductive system of females, males, and differentiated individuals. The mating exp...

de Oliveira, Leo Jaime Filgueira [UNESP]; Tudge, Christopher; Zara, Fernando José [UNESP]Made available in DSpace on 2022-04-29T08:34:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; The ultrastructure of spermatophores and spermatozoa of freshwater crabs are little known, and a description of characters unique to this taxon is lacking. In this study, we describe and compare the ultrastructure of spermatophores and spermatozoa of Dilocarcinus pagei, Zilchiopsis oronensis and Valdivi...
Much more than hooked: Setal adaptations for camouflage in Macrocoeloma trispin...
Lianos, Laira [UNESP]; Mollemberg, Michelle [UNESP]; Colavite, Jessica [UNESP]; Lopes e Silva, Amanda [UNESP]; Zara, Fernando José [UNESP]Made available in DSpace on 2022-04-29T08:36:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Several majoid crabs are known to adhere exogenous materials to their bodies, a behaviour called decoration. Until now, the adhesion of exogenous materials to the body is most attributed to the well-known hooked setae. Here, we analys...

Zara, Fernando José [UNESP]; Diogo Reigada, Alvaro Luiz [UNESP]; Domingues Passero, Luiz Felipe [UNESP]; Toyama, Marcos Hikari [UNESP]Made available in DSpace on 2022-04-28T20:51:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2009-02-01; Leeches exhibit a marked scope of diversity, including different kinds of symbiosis. The aim of the present study was to demonstrate through biochemical and histological analysis that a species of piscicolid leech, Myzobdella platensis, is a true parasite of blue crabs, feeding on their hemolymph and us...

Zara, Fernando José [UNESP]; Bution, Murillo Lino [UNESP]; Caetano, Flávio Henrique [UNESP]Made available in DSpace on 2022-04-28T21:00:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-04-14; The post-embryonic development of Camponotus textor is a crucial phase for the colony, since the nest is built with larval silk. Larvae of C. textor (n=200) were randomly collected from the nest, and head capsules were measured, and prepared for SEM. The body presents the pogonomyrmecoid shape and it is...

No. of bitstreams: 0 Previous issue date: 2021-01-01; In brachyuran crabs, the complexity of the copulatory system provides important information about the systematics of the group. Here we used scanning electron microscopy and light microscopy to provide information about the morphological changes during the gonopods ontogeny in the spider crab Mithraculu...

No. of bitstreams: 0 Previous issue date: 2020-01-01; The transgenic soybean expressing the cry1Ac insecticidal gene of the Bacillus thuringiensis bacterium has been widely adopted in agriculture. This bacterium acts as an efficient control agent of pest insects due to the expression of different proteins with entomopathogenic activity such as Cry and Vip....
Parabronchial remodeling in chicks in response to embryonic hypoxia
do Amaral-Silva, Lara [UNESP]; Lambertz, Markus; Zara, Fernando José [UNESP]; Klein, Wilfried [UNESP]; Gargaglioni, Luciane Helena [UNESP]Made available in DSpace on 2019-10-06T16:33:56Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; The embryonic development of parabronchi occurs mainly during the second half of incubation in precocious birds, which makes this phase sensitive to possible morphological modifications induced by O2 supply limitation. Thus, we hypothesized that hypoxia during the embryonic phase of parabronchial develo...
