Abstract Parasitic diseases, like avian malaria, play a relevant impact on wild avifauna around the world, putting threat to biodiversity, principally in endemic zones. For this research, we collected 171 blood samples from 21 bird species different locations within Atlantic Rainforest, global endemism center. These were analyzed using morphological, molecular, and phylogenetic approach. Our findings reveal presence of Plasmodium cathemerium, widespread pathogenic parasite hosts....
The gastrointestinal tracts of most herbivorous mammals are colonized by symbiotic ciliates the subclass Trichostomatia, which form a well-supported monophyletic group, currently composed ∼1,000 species, 129 genera, and 21 families, distributed into three orders, Entodiniomorphida, Macropodiniida, Vestibuliferida. In recent years, trichostomatid have been playing part in many relevant functional studies, such as those focusing host feeding efficiency optimization investigating their role...
The way an animal uses the home range and territory often vary in time according to its breeding state habitat complexity. Adult dispersal can follow partner replacement, however little is known about seasonal/sex variation replacement tropical passerines. Here we tested if size of Rufous Hornero Furnarius rufus varies between non-breeding seasons this consistent across three distant populations Brazil (UFJF, UnB, MT). In addition, described frequency replacements relation sex two those...
Glycoside hydrolases (GHs) are carbohydrate-active enzymes that assist the hydrolysis of glycoside bonds complex sugars into carbohydrates. The current standard GH family classification is available in CAZy database, which based on similarities amino acid sequences and curated semi-automatically. However, with exponential increase data availability from genome sequences, automated methods required for fast annotation coding sequences. Currently, dbCAN database offers automatic annotations...
Abstract The 18S rDNA was used to infer oral ciliature patterns of evolution within the family Ophryoscolecidae, with addition five new sequences ciliates from genus Ostracodinium . Our data confirmed monophyly subfamilies Entodiniinae and Ophryoscolecinae, but more analysis would be required for definition status subfamily Diplodiniinae. infraciliature reflect evolutionary divergence in Ophryscolecidae, observing on Entodinium ‐type, Diplodinium Epidinium Ophryoscolex ‐type. ancestral ‐type...
Many bird species avoid traditional traps such as mist nets, thus alternative trapping methods are often needed. The Rufous Hornero (Furnariidae: Furnarius rufus) is one that was captured so far using conventional netting in rural areas or nest-targeted traps, which risk nest damage and abandonment. Here we describe the novel rise-up mist-netting (RUM) protocol its catchability for wary territorial an urban area. RUM trap allowed us quickly capturing 40 individuals even paved parking lots...
The genus Metadinium includes ophryoscolecid ciliates, with two retractile ciliary zones in the anterior body portion, broad skeletal plates, a lobed macronucleus and contractile vacuoles. Species belonging to this were recorded several geographical locations different host species. However, they mostly described based on single ciliatological technique, until now, there is only one description of infraciliary pattern ciliates (Metadinium medium). present study performs morphological...
Abstract Haemoproteus spp. are protozoan parasites found in birds around the world. These identified through morphology of gametocytes, phylogenetic analysis based on mitochondrial cytb gene, and parasite’s geographic distribution. The absence erythrocytic merogony, high intraspecific genetic variation low parasitemia wild makes it essential to use integrative approaches that assist identification these parasites. Thus, microscopic molecular analyses, combined with spatial distribution, were...
The objective of this study was to assess whether the straining rumen content samples influences estimation protozoal density. Ninety were obtained from 30 cattle (three per animal). subjected one three treatments at moment collection: 1) fixation informalin without straining(control treatment), 2) before informalin, or 3)straining after informalin.To test hypothesis variation in protozoa composition samples, multivariate analyses with non-metric multidimensional scaling (NMDS) carried out....
The genus Rhabdostyla is one of the oldest family Epistylididae, it was described over 120 years ago and has more than 40 species considered valid. This group went through several systematic changes throughout its existence due to lack taxonomic information, said be essential, for most that compose it, some these are still questioned. In order better understand validate relationships identified this genus, present work makes a brief review related genera, Opisthostyla Orborhabdostyla. A...
High infestations of epibiont ciliates on vertebrates or invertebrates are normally related to aquaculture tanks similar environments, and the importance this relationship in natural habitats is often disregarded. Here, we describe first record high infestation Aegla serrana South America conduct a brief morphological phylogenetic characterization these ciliates. Our findings confirm that cases metazoans can indeed occur environments.
There is a marked disparity in the state of knowledge Holartic x Neotropical species freshwater snail family Physidae; incipiency data on physids reflecting lower number dedicated specialists. The gaps have led to historical uncertainty about validity. Revisiting essential reduce taxonomic impediment and delineating their probable distribution first step attain this purpose. We aimed at critically analyze occurrence records South American physids, compiled through an intensive search...
The current study proposes to investigate the diversity and phylogeny of trypanosomes parasitizing wild birds from Brazilian Atlantic Forest. Cytological examination was carried out by light microscopy blood smears positive were selected for amplification 18S rDNA sequence through PCR. resulting amplicons subjected purification, cloning, sequencing analysis. Phylogenetic reconstruction conducted, including all avian representative's lineages. A total ten bird samples species Turdus flavipes...
