Elasmobranchs, the group of cartilaginous fishes that include sharks and rays, are especially vulnerable to overfishing due low fecundity late sexual maturation. A significant number elasmobranch species currently overexploited or threatened by fisheries activities. Additionally, several recent reports have indicated there has been a reduction in regional population sizes. Brazil is an important player one largest importers shark meat. However, carcasses entering meat market usually had...
The genus Obama Carbayo et al., 2013 includes 38 species, being the most species-rich within Geoplaninae. Species of this show a similar anatomy regarding their copulatory apparatus, which may hinder species differentiation. In study, we describe two new presenting marbled colour pattern, found in different phytophysionomies Atlantic Forest, namely Semi-deciduous Forest and Araucaria Forest. Both can be distinguished from congeners, as well each other, by pattern eye arrangement combined...
The genera Cratera Carbayo et al., 2013 and Obama 2013, belonging to the subfamily Geoplaninae, were recently proposed encompass some of species that belonged genus Geoplana Stimpson, 1857. Herein we describe two new occurring in areas ombrophilous forest which belong southern portion Brazilian Atlantic Rain Forest. are sympatric their type-locality. In general, both herein described match diagnostic characteristics genera. However, these features noteworthy when characters taken into...
Microplastics are omnipresent in the atmosphere, terrestrial and aquatic ecosystems, food beverages. They may cause risks to biodiversity human population. The present study aims assess concentrations of microplastics raw drinking water Sinos River Southern Brazil. was collected at eight locations along residences supplied with treated river water. samples were processed by dying plastic particles Nile Red counting fluorescence microscopy. showed an average 330.2 L−1 105.8 L−1. Fibers most...
Population studies of invasive species allow us to understand how invaders react new biotic and abiotic conditions, native invasion. We evaluated the colonisation efficiency invader Zaprionus indianus (Gupta), in urban area Porto Alegre city, southern Brazil. Samples flies were taken from three parks, ecological indexes used based on frequency sampled species. The calculated for breeding feeding sites separately. highest frequencies Z. compared other drosophilids registered during seasons...
Farming practices may reshape the structure of watersheds, water quality, and health aquatic organisms. Nutrient enrichment from agricultural pollution increases disease pressure in many host–pathogen systems, but mechanisms underlying this pattern are not always resolved. For example, nutrient should strongly influence pools environmental bacteria, which has potential to alter microbiome composition animals their vulnerability disease. However, shifts host have received little attention as...
Abstract Climate change has led to an alarming increase in the frequency and severity of wildfires worldwide. While it is known that amphibians have physiological characteristics make them highly susceptible fire, specific impacts on their symbiotic skin bacterial communities (i.e., bacteriomes) infection by deadly chytrid fungus, Batrachochytrium dendrobatidis , remain poorly understood. Here, we address this research gap evaluating effects fire amphibian bacteriome subsequent risk...
The cracks in concrete serve as pathways for aggressive agents, leading to deterioration. One approach addressing these and enhancing structures durability is the use of self-healing such bacteria used heal cementitious matrices. Bacteria can be found several environments, their identification healing viability must evaluated prior In this study, distinct indigenous were collected from soil industrial yards associated with cement industry. These identified incorporated mortar mixtures 18%...
Studying host-associated microbiome assembly is key to understanding microbial and host evolution health. While honey bee microbiomes have been central models for such investigations among pollinators, they overlook the diversity of eusocial dynamics multi-kingdom interactions. Stingless bees, highly managed bees that rely on yeast larval development, offer a valuable complementary system study assembly, within an eco-evolutionary framework. Using amplicon sequencing, metagenomics,...
The South American sea lion (Otaria flavescens) is widely distributed along the southern Atlantic and Pacific coasts of America with a history significant commercial exploitation. We aimed to evaluate population genetic structure evolutionary its distribution by analyses mitochondrial DNA (mtDNA) 10 nuclear microsatellites loci. analyzed 147 sequences mtDNA control region genotyped 111 individuals for microsatellite loci, representing six populations (Peru, Northern Chile, Southern Uruguay...
The genetic structure of bottlenose dolphin communities found along the southern Brazilian coast is reported in this study. Genetic analysis using biopsy samples from free ranging dolphins and tissue stranded revealed a fine-scale population among three distinct groups. first genetically group was composed resident Laguna with high degree site fidelity. second one photo-identified dolphin, previously recognised by its interaction fishermen, that near mouth Tramandaí Lagoon. Moderate nuclear...
We assessed the level of genetic variability and population structure common bottlenose dolphin (Tursiops truncatus) in tropical subtropical portions southwestern Atlantic Ocean compared results with previous morphological findings. analyzed 109 samples dolphins that were sequenced for control region mtDNA genotyped seven polymorphic microsatellite loci. The suggested species this can be separated two major biological units, northern southern, an area parapatry at southern Brazil. unit seems...
Drosophila paulistorum Dobzhansky & Pavan, 1949 had initially been considered absent in anthropogenically disturbed environments, but 1985 the detection of species Porto Alegre city, southern Brazil, suggested its potential to colonize new habitats and laid foundations for ecologic studies on this species' populations. This study followed variations D. populations town almost 20 years after first local record. Drosophilid specimens were collected sites with different urbanization grades...
Salminus is a genus composed of four species migratory fishes and top predators. Although this group has great economic ecological importance, the level diversity not yet completely clarified. Our goal was to detect if taxonomic problem consequence lineage divergence within species, and, so, whether these divergences are sufficient flag potentially undescribed taxa. We employed standard DNA barcoding analyses generalized mixed Yule-coalescent model (GMYC) using one mitochondrial (COI) marker...
In agricultural systems, interactions between plants and microorganisms are important to maintaining production profitability. this study, bacterial communities in floodwaters of rice fields were monitored during the vegetative reproductive stages plant development using 16S amplicon sequencing. The study was conducted south Brazil, crop years 2011/12 2012/13. Comparative analyses showed strong differences associated with two developmental stages. During stage, 1551 operational taxonomic...
Sigmodontinae is a very rich clade of rodents that widespread throughout the Neotropics. The arboreal mice Juliomys comprise poorly known branch, with incomplete information about species richness, phylogenetic position, and geographic distribution. Based on sample from Atlantic Forest Southern Brazil, we name describe new for genus. This can be distinguished others in genus by its karyotype, morphological traits, cytochrome b (Cytb) gene sequence. It has unique karyotype (2n = 32, FN 48),...
