The present article tried to establish dark/light preference in five different species of teleosts. We proposed, using the data obtained with this method zebrafishes (Danio rerio), Cardinal-tetras (Paracheirodon axelrodi), lambaris (Astyanax altiparanae), Nile tilapias (Oreochromis niloticus), guppies (Poecilia reticulata) and banded-knife fishes (Gymnotus carapo), that for dark environments is a reliable low-cost index anxiety/fear those species. A scototactic pattern exploration was found...
Abstract This article documents the addition of 153 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: B rassica oleracea, rycon amazonicus, D imorphandra wilsonii, E upallasella percnurus, H elleborus foetidus, I pomoea purpurea, P hrynops geoffroanus, rochilodus argenteus, yura sp. , S ylvia atricapilla, T eratosphaeria suttonii, rialeurodes vaporariorum and rypanosoma brucei . These cross‐tested on coccicinea, cuprea,...
ABSTRACT Tools to discriminate products from captive and wild sources will improve wildlife sustainability, stable isotopes of carbon nitrogen can be potentially useful for this. In this study, we evaluated δ 15 N 13 C in Caiman latirostris skins individuals (from Argentina Brazil), Argentina), leathers tanned skins) both Argentina). addition, compared the isotopic signatures caiman claws caimans Brazil. The main goal study was evaluate possible differences variability between skins,...
The innate immune activity of the freshwater turtle Phrynops geoffroanus (Schweigger, 1812) was investigated, using a sheep-red-blood cell hemolysis assay. time- and concentration-dependent hemolytic plasma low compared to that reported for other reptiles. However P. exhibited higher at elevated temperatures, resulting in temperature-dependent hemolysis. sensitivity temperature could be interpreted as mechanism by which turtles use basking behavior elevate body temperature, thus enhancing...
The Yellow-spotted River Turtle ( Podocnemis unifilis Troschel, 1848) and the South American (Podocnemis expansa (Schweigger, 1812)) are two turtles species that widely distributed have ecological, economic, cultural importance in Amazon basin. Although sympatric regarding most of their distribution, few studies addressed coexistence these species. To examine this, we analyzed trophic level primary carbon source from diets both Baixo Araguaia, Tocantins, Brazil, using stable isotope analyses...
Abstract Large predators have disproportionate effects on their underlying food webs. Thus, appropriately assigning trophic positions has important conservation implications both for the themselves and prey. Large-bodied are often referred to as apex predators, implying that they many levels above primary producers. However, theoretical considerations predict higher lower position with increasing body size. Nitrogen stable isotope values ( δ 15 N) increasingly replacing stomach contents or...
Strategies to minimise intraspecific competition are common in wild animals. For example, individuals may exploit food resources at different levels of the chain. Analyses stable isotopes particularly useful for confirming variations an niche because chemical composition animals tends reflect both consumed and habitats occupied by species. However, studies using this methodology investigate neotropical crocodilians scarce. This study aimed verify existence ontogenetic sexual variation...
Natural variation in stable isotope ratios is a useful tool diet studies. However, the correct interpretation of isotopic data reliant on proper estimates discrimination factors. This study aimed to describe magnitude factors carbon and nitrogen isotopes between tissues (Δ13Ctissue-diet Δ15Ntissue-diet) Broad-snouted Caiman (Caiman latirostris) verify potential differences age classes. The (δ13C δ15N) were determined samples two tissue types (claw scute) collected from 18 captive animals 15...
Abstract Motivation SIA‐BRA is a data set that compiles stable carbon (C) and nitrogen (N) isotope ratios of terrestrial aquatic animals sampled in Brazilian biomes coastal marine areas. Stable are helpful animal ecology for several reasons; instance, they can be used to investigate trophic niches, energy sources (diet tracing) track migration patterns. The Neotropics considered one the most undersampled regions world. Given Brazil continental country where dietary species under‐assessed, we...
Oral bacterial microbiota and traumatic injuries of free-ranging Phrynops geoffroanus (Testudines, Chelidae) in southeastern Brazil.During 2006 2007, we collected geoffroanus, from two anthropogenically altered rivers Brazil.Oral microbiological samples were taken for isolation aerobic facultative anaerobic bacteria; a physical examination was performed; evaluated possible effects on the turtles' health.Twenty-nine species bacteria isolated Piracicaba River turtles (n=10), twenty-four...
Crocodilians are ectothermic animals. For this reason, the environmental temperature has substantial effects on their physiology and behavior. The thermoregulatory behavior of these animals involves selective use different types environments. This enables them to reach level for metabolic activities. study aimed determine influence sex, body size, reproductive stage (T b) adult broad-snouted caiman (Caiman latirostris) in captivity. Thermal sensors were surgically implanted peritoneal cavity...
Information on the home range and movement patterns of Neotropical crocodilians is scarce for most species, despite being essential developing management conservation plans. The broad-snouted caiman (Caiman latirostris) a crocodilian with wide geographical distribution in South America. This species inhabits artificial reservoirs (e.g., small weirs) silvicultural areas. However, its use space such circumstances still unknown. present study aims to estimate silviculture-dominated landscape...
Neste estudo reportamos pela primeira vez a ocorrência de larvas Chironomus inquinatus Correia, Trivinho-Strixino & Michailova vivendo no casco do cágado Phrynops geoffroanus Schweigger, possivelmente em função da intensa acumulação sedimento, um rio poluído região Neotropical.
The isotopic composition ( δ13C and δ 15N) of muscle, carapace claw was determined from six wild individuals Phrynops geoffroanus (Schweigger, 1812) in order to verify the variation between those tissues. mean values e 15N were, respectively, -19.48 ± 0.81‰ (-20.8 - -18.64‰) 7.23 0.67‰ (6.49 8.3‰) for -16.52 0.98‰ (-17.88 -15.43‰) 7.29 0.54‰ (6.74 7.97‰) -18.57 0.97‰ (-19.97 -17.26‰) 4.36 0.33‰ (3.93 4.79‰) claw. We found a significant difference tissues evaluated both δ15N. Muscle were...
Ecological niche is the multidimensional space comprising resources used by an organism. Intraspecific variation in resource exploitation common reptile populations to maximize coexistence of individuals. The use stable isotope analysis effective tool when there are variations exploitation, since it can provide quantitative information about food consumption and habitat use. Mesoclemmys vanderhaegei (Bour, 1973) a medium-sized turtle with limited distribution south central Brazil Paraguay....
