Neotropical Monogenea. VIII: Revision of Urocleidoides (Dactylogyridae, Ancyrocephalinae)
Description de 2 especes nouvelles d'Urocleidoides, de 4 especes nouvelles du nouveau genre Vancleaveus, de 6 especes nouvelles du nouveau genre Cosmetocleithrum et de 8 especes nouvelles du genre
Phylogeny and a revised classification of the Monogenoidea Bychowsky, 1937 (Platyhelminthes)
A hypothesis (CI=57.3%) on the evolutionary relationships of families comprising the class Monogenoidea is proposed based on 141 character states in 47 homologous series and employing phylogenetic systematics and supports independent origins of the Montchadskyellidae within the Polyonchoinea and of the Neodactylodiscidae and Amphibdellatini within the order Dactylogyridea.
Neotropical Monogenoidea. 41: New and previously described species of Dactylogyridae (Platyhelminthes) from the gills of marine and freshwater perciform fishes (Teleostei) with proposal of a new
Les especes suivantes, parasites des branchies de teleosteens marins ou d'eau douce du Bresil, du Perou, Venezuela and/ou Mexique sont decrits : Euryhaliotrema chaoi n.
Coevolution of the Monogenoidea (Platyhelminthes) based on a revised hypothesis of parasite phylogeny.
A revised hypothesis for the phylogeny of the Subclass Polyonchoinea (Monogenoidea) was constructed employing phylogenetic systematics and suggested that primary extinction with secondary dispersal of polystomatids to the Dipnoi may not be necessary to explain extant parasite distributions.
Phylogeny, coevolution, and revision of the hexabothriidae price, 1942 (Monogenea)
Tests for coevolution with phylogenetic hypotheses proposed by Compagno (1977, American Zoologist 17 : 303–322) for elasmobranchs suggest a relatively high evolutionary independence for hexabothriids.
Neotropical Monogenea. 15. Dactylogyrids from the gills of Brazilian Cichlidae with proposal of Sciadicleithrum gen. n. (Dactylogyridae)
9 new ancyrocephalines from cichlid hosts are described, and Sciadicleithrum gen. n.
The phylogenetic status of the Ancyrocephalidae Bychowsky, 1937 (Monogenea: Dactylogyroidea).
Phylogenetic analysis of selected subfamily and family taxa within the Dactylogyroidea indicates that the Ancyrocephalidae Bychowsky, 1937, is unnatural and suggests that revision of the Ancentylogyridae is necessary.
Lethargic crab disease: multidisciplinary evidence supports a mycotic etiology.
Phylogenetic analyses not only confirm the diagnosis of the LCD fungus in crab tissues as an ascomycete, but also suggest a close relationship with members of the subphylum Pezizomycotina.
Postglacial north-south expansion of populations of Rhizophora mangle (Rhizophoraceae) along the Brazilian coast revealed by microsatellite analysis.
The lowest variability observed in the southern populations of the red mangrove most likely reflects their recent age, associated with allelic reduction, resulting from the consecutive founder events that followed subsequent colonization of estuaries during the gradual warming by the end of the last glacial period.
Morphology and histology of the male reproductive system of the mangrove land crab Ucides cordatus (L.) (Crustacea, Brachyura, Ocypodidae)
Production of male gametes was continuous throughout the study period, indicating that males of this species are physiologically capable of reproducing all year long.
