Aggregations and reproductive events of the narrownose smooth-hound shark (Mustelus schmitti) in relation to temperature and depth in coastal waters of the south-western Atlantic Ocean (38–42°S)
(Csiro Publishing, 2017-04)
Knowledge of environmental influence on reproductive dynamics in chondrichthyans is critical for effective management. The present study assessed the potential influences of temperature and depth on aggregations and ...
Changes in the distribution density of locate, Thaisella chocolata (Duclos, 1832) (Gastropoda, Thaididae) as an indicator for predicting their reproductive events

A safe haven for potential reproductive aggregations of the critically endangered Brazilian guitarfish (Pseudobatos horkelii)
(2021-01-01)
Brazilian endemic batoid elasmobranch populations have declined dramatically in the past 40 years due to anthropic activities (e.g., overfishing). The Brazilian guitarfish, Pseudobatos horkelii, included in the IUCN red ...
On the Production, Mating and Behavior of Males in Synoeca surinama (Vespidae: Polistinae: Epiponini)
(Univ Estadual Feira Santana, 2020-09-01)
In colonies of Neotropical swarm-founding wasps (Epiponini), males are thought to be produced only in periods when there are many queens present. Little information is available regarding male behavior in and out of the ...
Patagonian grouper Acanthistius patachonicus (Jenyns, 1840) forms massive spawning aggregations in the Southwest Atlantic
(Wiley Blackwell Publishing, Inc, 2020-10)
Here we describe massive spawning aggregations and seasonal changes in the large‐scale distribution of the Patagonian grouper Acanthistius patachonicus in the Southwest Atlantic based on three sources of information: (a) ...
Equine cloning: In vitro and In vivo development of aggregated embryos
(Society For The Study Of Reproduction, 2012-07)
The production of cloned equine embryos remains highly inefficient. Embryo aggregation has not yet been tested in the equine, and it might represent an interesting strategy to improve embryo development. This study evaluated ...
Population genetic structure of Rhizoctonia oryzae-sativae from rice in Latin America and its adaptive potential to emerge as a pathogen on urochloa pastures
(2017-01-01)
The fungus Rhizoctonia oryzae-sativae is an important pathogen that causes the aggregated sheath spot disease on rice. In this study, we investigated the genetic structure of rice-adapted populations of R. oryzaesativae ...
Competição larval em Chrysomya megacephala (F.) (Diptera: Calliphoridae): efeitos de diferentes níveis de agregação larval sobre estimativas de peso, fecundidade e investimento reprodutivoLarval competition in Chrysomya megacephala (F.) (Diptera: Calliphoridae): effects of different levels of larval aggregation on estimates of weight, fecundity and reproductive investment

Gregarious behavior of two species of Neotropical harvestmen (Arachnida: Opiliones: Gonyleptidae)
(American Arachnological SocietyCollege Park, 2012)
We present the first record and description of the gregarious behavior of the Neotropical harvestmen Serracutisoma proximum (Mello-Leitao 1922) and Serracutisoma spelaeum (Mello-Leitao 1933) (Opiliones: Gonyleptidae: ...
