Abstract This article documents the addition of 512 microsatellite marker loci and nine pairs Single Nucleotide Polymorphism (SNP) sequencing primers to Molecular Ecology Resources Database. Loci were developed for following species: Alcippe morrisonia , Bashania fangiana, fargesii Chaetodon vagabundus Colletes floralis Coluber constrictor flaviventris Coptotermes gestroi Crotophaga major Cyprinella lutrensis Danaus plexippus Fagus grandifolia Falco tinnunculus Fletcherimyia fletcheri,...
Myotis nigricans presents few and controversial reproductive data, which indicate geographical variation in reproduction. Thus, this study aimed to evaluate the seasonal modifications testicular epididymal morphologies a tropical environment, submitting these organs morphometric immunohistochemical analysis. The observations revealed that species two peaks of spermatogenic activity followed by periods total regression (a quiescent pre-pubertal-like morphology, where only Sertoli cells...
Abstract We know little about the process of spermatogenesis in bats, a great and diverse clade mammals that presents different reproductive strategies. In present study, six species Neotropical bats was investigated by light microscopy. On basis chromatin condensation, nuclear morphology, relative position to basal membrane formation flagellum, three types spermatogonia were recognized: dark type A (A d ), pale p B; development spermatids divided into seven steps. With exception Myotis...
Abstract Bats present unique features among mammals with respect to reproduction, and although neotropical bats do not have a hibernation period, many of their reproductive characteristics vary seasonally interspecifically. Thus, this work aimed examine the structures 18 species belonging five families Brazilian bats. The gross anatomy testes varied little; however, epididymis Emballonuridae Vespertilionidae showed exceptional large elongation caudal region. We observed wide variation in...
Bats are flying mammals distributed worldwide known to host several types of Coronavirus (CoV). Since they were reported as the probable source spillover highly pathogenic CoV into human population, investigating circulation this virus in bats around world became great importance. We analyzed samples from 103 two distinct regions Brazil. Alphacoronavirus genus was detected 12 animals, 11 São José do Rio Preto—SP region and 1 Barreiras—BA region, resulting a prevalence 17.18% 2.56%...
Chiroptera, the second largest mammalian order, presents different reproductive strategies and unique features. However, there are few reports regarding male accessory glands (RAGs) in Chiroptera. Thus, aim of present study was to characterise RAGs exclusively neotropical bat Artibeus planirostris (Chiroptera: Phyllostomidae) macroscopically, microscopically ultrastructurally. The were composed a prostatic complex with two regions (ventral dorsal) paraurethral bulbourethral glands, but no...
Viruses are important agents of emerging zoonoses and a substantial public health issue. Among viruses, an group arboviruses, which characterized by being maintained in nature cycles involving hematophagous arthropod vectors wide range vertebrate hosts. Recently, bats have received increasing attention as source for the emergence possible viral reservoirs. there many representatives genera Flavivirus Alphavirus, responsible epidemics such Dengue virus, Zika virus Chikungunya virus. Due to...
Myotis nigricans is an endemic species of vespertilionid bat, from the Neotropical region, that resembles temperate zone bats in their reproductive cycle; presenting annual cycle with two periods testicular regression, which are not linked to apoptotic process and seems be directly any seasonal abiotic variation. Thus, this study aimed ultrastructurally evaluate cycle. The regression could divided into four periods: active; regressing; regressed recrudescence; all distinct characteristics....
Due to their wide geographical distribution, bats suffer considerable influence from abiotic factors on reproductive strategies, detected through behavioural or functional assessment of the gonads and accessory glands. The present study aimed characterise anatomically morphologically glands (RAGs) Molossus molossus (Molossidae) evaluate seasonal variations. RAGs were removed, fixed, sectioned after histological processing submitted following stains: haematoxylin–eosin, periodic acid–Schiff...
G- and C- banding patterns of seven species the bat family Molossidae, <i>Eumops glaucinus, E</i>. <i>perotis, Molossops abrasus, M</i>. <i>temminckii, Molossus ater, <i>molossus, </i>and <i>Nyctinomops laticaudatus, </i>were identified. Comparisons among karyotypes these showed extensive homologies between <i>E</i>. <i>ater, <i>abrasus, <i>N</i>. <i>laticaudatus, </i>demonstrating inter-...
Myotis nigricans is a species of vespertilionid bat, whose males show two periods total testicular regression within the same annual reproductive cycle in northwest São Paulo State, Brazil. Studies have demonstrated that its epididymis has an elongation caudal portion, which stores spermatozoa during period July, but they had no sperm November. Thus, aim this study was to analyze impact epididymal morphophysiology and patterns hormonal regulation. The results demonstrate continuous activity...
Abstract Artibeus lituratus is one of the most recognized bat species in neotropics, probably due to its high abundance urban areas. Despite wide distribution, morphology and physiology reproductive organs remain unclear. Thus, aim present study was describe histology female this species, evaluate morphological variations during different phases (nonreproductive, pregnant, lactating, etc.). Thirty adult females were collected, divided into six (6) sample groups, according status, submitted...
ABSTRACT This study aimed to morphologically characterize and compare the male reproductive accessory glands (RAGs) of bats belonging five Brazilian subfamilies family Phyllostomidae ( Carollia perspicillata —Carollinae; Desmodus rotundus —Desmodontinae; Glossophaga soricina —Glossophaginae; Phyllostomus discolor —Phyllostominae Platyrrhinus lineatus —Stenodermatinae). The demonstrated that RAGs phyllostomid were comprised a pair extra‐abdominal bulbourethral an intra‐abdominal complex,...
Cytogenetic and random amplified polymorphic DNA analyses carried out in the species Leptodactylus podicipinus, L. ocellatus, labyrinthicus, fuscus from rural urban habitats of northwest region São Paulo State, Brazil, showed that karyotypes (2n = 22), constitutive heterochromatin distribution nucleolus organizer (NOR) location did not differ between populations two environments.The situ hybridization with an rDNA probe confirmed NORs on chromosome 8 revealing tandem duplication one...
Abstract Despite the large number of species, their wide distribution, and unique reproductive characteristics, Neotropical bats have been poorly studied, important aspects reproduction these animals not elucidated. We made an ultrastructural analysis spermatogenesis in Molossus molossus (Molossidae). The process spermatogonial differentiation is similar to that found other also relatively Primates, with three main spermatogonia types: A d , p B. Meiotic divisions proceed similarly those...
