Abstract:

Most aquatic mammals have complex social and communication systems. Interestingly, little is known about otters’ vocal communication compared to other aquatic mammals. Here, for the first time, we acoustically describe vocalizations of the neotropical otter (Lontra longicaudis), a solitary and endangered New World otter species. We recorded vocalizations and behavioral contexts from six captive neotropical otters at Projeto Lontra, Santa Catarina Island, Brazil. Analysis of acoustic parameters were used to classify the vocalizations according to structure and context. We describe six call type

AbstractThe gonads of six adult giant otter males (Pteronura brasiliensis) and of one adult neotropical otter male (Lontra longicaudis) were analyzed both for histology and gross anatomy. The mean testes mass/body mass ratio in giant otters was 0.046 ± 0.0071%. The presence of spermatozoa inside the seminiferous and epididymal tubules revealed that two-year-old giant otters were already sexually mature. The mean diameter of the seminiferous and epididymal tubules of mature giant otters was 126.3 ± 13.37 μm and 198.8 ± 31.19 μm, respectively. The small amount of spermatozoa in the testes and ep

The Neotropical otter Lontra longicaudis is one of the least studied mammals of the Yucatán Peninsula and its presence in some water bodies of this region is questionable. Laguna Bacalar is the largest freshwater body located in the Yucatán Peninsula and faces several conservation problems due to its high potential for tourism development. We confirmed the presence of L. longicaudis in Laguna Bacalar by conducting interviews with residents, and the search for direct (sightings) and indirect (e.g., footprints) evidence of the species in 2013.

Abstract:

The Neotropical otter, Lontra annectens, is a predator specialized in aquatic prey, and the main diet of this otter is fish, supplemented mainly by crustaceans and opportunistically by mollusks, insects, and vertebrates such as mammals, amphibians, birds, and reptiles. Occasionally, they eat fruits. This study was conducted on the El Despoblado River near Villa Comaltitlán, in southern Chiapas. We carried out monthly visits along the riverbanks to collect otter scats from April 2018 to April 2019 and found that insects make up more than half of the diet of otters living in this river.

ABSTRACT The Neotropical otter, Lontra longicaudis (Mustelidae) is a semi-aquatic mustelid that exploits a variety of freshwater habitats. To understand the relative influence of human activities and environmental factors affecting its distribution and habitat use, we conducted systematic, seasonal surveys of otter signs along the middle Guamá River, in Pará state in the eastern Brazilian Amazon.

Abstract:

Nocturnal activity of tropical otters is rarely reported. To date no studies have documented den use by sympatric giant (Pteronura brasiliensis) and neotropical otters (Lontra longicaudis). We used camera-traps to monitor den use by sympatric otters along an equatorial Amazonian river. Camera-traps provided evidence that giant otters were more nocturnal around dens than sympatric neotropical otters. Nocturnal activity was recorded in 11% of giant otter photos (n = 14 of 125 photos), but was recorded only once for neotropical otters. Den use by giant and neotropical otters overlapped spatially

Abstract:

Communal latrines have important biological and ecological roles for the latrine builder species and for other taxa that visit these sites and use feces to obtain nutrients and microorganisms that aid in digestion of compounds hard to process. Nonetheless, coprophagous animals must deal with the costs associated with parasites and other pathogenspresent in latrines. Parasites and pathogens are found in Neotropical otter latrines. This species is carnivorous and uses latrines for territorial marking. The objective of this study was to identify vertebrate species associated with otter latrines a

Abstract:

This work represents an analysis of the presence of Lontra longicaudis in the Cubatão River, Santa Catarina, Brazil. The influence that temperature and precipitation can have on the collection of excrements of the species is examined. The composition of the diet is determined by the collected excrement. From 2006 to 2007, 255 feces were collected using rafting boats in the study area, which is characterized by strong rapids and waterfalls. Precipitation and temperature data from January 2006 to September 2007 were obtained. The Kruskal-Wallis test was used to determine the seasonal difference

Abstract:

The Neotropical otter is an important mammal in aquatic ecosystems due to its trophic position as a top predator, therefore is a valuable medium and long term bio monitor of the environment. Due to its crepuscular-nocturnal behavior, studies on this species primarily rely on non invasive methods, such as the analysis of feces and anal-glands jellies, which allow for various ecological and population inferences. With recent advances in molecular techniques, these non-invasive samples have greatly contributed to the understanding of wild populations. Among the relevant population characteristics

Abstract:

The finding of a Neotropical river otter (Lontra longicaudis) cub occupying a shelter in a hollowed treetop is reported. The observation was made in a seasonally flooded forest in Central Amazonia, during the high water peak of the annual inundation cycle. A literature review indicates that this is the first description of a shelter of the species, both in a hollowed tree and in Amazonia. This observation can indicate a strong relationship between the species' breeding cycle with the annual dynamics of Amazonian rivers. We discuss potential advantages and disadvantages of breeding when water l

The study of the behavior of the Lontra longicaudis was conducted from January to April 2010. The main objective was to determine the individual and social patterns of three otters in captivity, correlating the data with average temperatures. The methodology was based on random observations, the ad libitum method, and the focal animal method, during which the animals are observed thanks to standardized spreadsheets. The sampling effort was four hours daily, resulting in a total of 196 hours. Twenty-nine listed activities were divided into two categories and ten sub-categories. The adult couple

The present study was based on the analysis of spraints (n = 294) collected between December 2005 and November 2007. The importance of each type of prey was determined by absolute and relative frequency. Niche breadth was also estimated. The results were reported as mean (± SD) of relative frequencies. Fish were the main prey found in spraints (57.8 ± 7.0%). Fish from Callichthyidae family were the main prey, followed by Cichlidae, the species Hoplias malabaricus and the family Characidae. The frequencies of other fish and taxa were lower than 13.9% (absolute frequency) and 5.6% (relative freq
