Founder effects drive the genetic structure of passively dispersed aquatic invertebrates
2018
Populations of passively dispersed organisms in continental aquatic habitats typically show high levels of neutral genetic differentiation, despite their high dispersal capabilities. Several evolutionary factors, including founder events and local adaptation, and life cycle features such as high population growth rates and the presence of propagule banks, have been proposed to be responsible for this paradox. Here, we have modeled the colonization process in these organisms to assess the impact of migration rate, growth rate, population size, local adaptation and life-cycle features on their population genetic structure. Our simulation results show that the strongest effect on population st…
Experimental Introgression To Evaluate the Impact of Sex Specific Traits on Drosophila melanogaster Incipient Speciation
2019
AbstractSex specific traits are involved in speciation but it is difficult to determine whether their variation initiates or reinforces sexual isolation. In some insects, speciation depends of the rapid change of expression in desaturase genes coding for sex pheromones. Two closely related desaturase genes are involved in Drosophila melanogaster pheromonal communication: desat1 affects both the production and the reception of sex pheromones while desat2 is involved in their production in flies of Zimbabwe populations. There is a strong asymmetric sexual isolation between Zimbabwe populations and all other “Cosmopolitan” populations: Zimbabwe females rarely copulate with Cosmopolitan males w…
Morphology of spermatheca in Scutelleridae (Hemiptera: Pentatomoidea) and its taxonomic significance
2016
AbstractStructures of spermatheca in 63 species of Scutelleridae (Hemiptera) representing 46 genera and all subfamilies currently recognised in the family were examined and compared. The morphology of three main parts of the spermatheca (receptacle, intermediate part, and spermathecal duct) was described and three main types of spermatheca in Scutelleridae were identified. The taxonomic importance of spermathecal features for the higher classification of scutellerids is discussed.
New data and taxa for Orthoptera Tettigoniidae and Acrididae from tropical Africa.
2017
The results of a long-term study on the Orthoptera collected in tropical Africa and preserved in different European natural history museums are reported. Horatosphaga bazeletae n. sp. is described from South Africa, Dapanera falxcercata n. sp. from Cameroon, Eurycorypha specularia n. sp. from Zambia (Tettigoniidae Phaneropterinae), and Eucoptacra popovi n. sp. (Acrididae Coptacrinae) from the Gabon. Furthermore, the new genus Pigalua n. gen. is described for Eulioptera insularis Ragge, 1980 from Annobón Is. (Equatorial Guinea). The new tribe Kevaniellini n. trib. is proposed for Kevaniella bipunctata Chopard, 1954. Besides, the hitherto unknown males of Eurycorypha flavescens (Walker, 1869)…
A Revised Phylogeny of Discocerinini (Diptera: Ephydridae) with an Emphasis on Structures of the Proboscis
2016
Supplementary diagnostic characters of genera in the tribe Discocerinini are suggested. A new genus Aquachasma Zatwarnicki, type species: Discocerina leucoprocta Loew, 1861 is described with 24 new combinations of all included species. Genus Polytrichophora is divided into the nominate subgenus and a new subgenus Sklodowskopa Zatwarnicki, type species: Clasiopa duplosetosa Becker, 1896. Genus Orasiopa is divided into the nominate subgenus and a new subgenus Reymontopa Zatwarnicki, type species: Discocerina mera Cresson, 1939. The shape of the proboscis of all genera of Discocerinini is provided, including variability of cibarium and pseudotracheae. The ventral receptacles of 6 genera (Aquac…
Maternal Caloric Restriction Implemented during the Preconceptional and Pregnancy Period Alters Hypothalamic and Hippocampal Endocannabinoid Levels a…
2016
Journal Article; Exposure to inadequate nutritional conditions in critical windows of development has been associated to disturbances on metabolism and behavior in the offspring later in life. The role of the endocannabinoid system, a known regulator of energy expenditure and adaptive behaviors, in the modulation of these processes is unknown. In the present study, we investigated the impact of exposing rat dams to diet restriction (20% less calories than standard diet) during pre-gestational and gestational periods on: (a) neonatal outcomes; (b) endocannabinoid content in hypothalamus, hippocampus and olfactory bulb at birth; (c) metabolism-related parameters; and (d) behavior in adult mal…
Morphology, performance and attachment function in Corynosoma spp. (Acanthocephala)
2018
Background: Functional inference on the attachment of acanthocephalans has generally been drawn directly from morphology. However, performance of structures is often non-intuitive and context-dependent, thus performance analysis should be included whenever possible to improve functional interpretation. In acanthocephalans, performance analysis of attachment is available only for Acanthocephalus ranae, a species that solely relies on the proboscis to attach. Here we compare body morphology and muscle arrangement in 13 species of Corynosoma, which use their spiny body as a fundamental holdfast. A basic performance analysis using live cystacanths of two representative species is also provided.…
