It has recently been categorized as vulnerable. This is the first study to evaluate D. patagonum interactions with potential predators in the surroundings of the dens. We monitored 20 burrows, using camera-traps, with a total of 5644 camera-days, obtained over two years (2015 and 2016). Five potential predator species were detected (Lycalopex griseus, Puma concolor, Leopardus geoffroyi, Salvator sp. and Chaetophractus villosus). L. griseus and L. geoffroyi were the species with the highest frequency of visits. Both species were photographed attacking the juveniles. Four out of five potential predator species registered presented agonistic interactions with adults of mara. Overlap between all species analyzed and mara was low to moderate, and potential predator visits to the surrounding of the burrows did not vary according to the presence of juveniles. Our r...

Estudiamos los efectos del extracto metanólico (MEx) del fruto de Prosopis torquata en la reproducción, histología y morfología del sistema reproductivo de las ratas Wistar macho. Las crías se distribuyeron al azar en cuatro grupos. Tres con dieta libre de fitoestrógeno más inyección por vía subcutánea con MEx, estradiol (E) y vehículo (Ve) respectivamente. El cuarto fue alimentado con dieta que contiene fitoestrógenos comerciales (Cf + Ve). No hubo cambios en valores de hormonas ni en concentración de espermatozoides entre grupos. MEx exhibió una maduración más lenta de testículos, escaso número de espermátidas alargadas y desorganización epitelial en órganos reproductores. El efecto disruptor de MEx, se ha observado previamente en ratas Wistar hembras.Endocrine disruptors from plants cause anomalies in the reproductive system of mammals.

In this paper we propose that aspects related to scientific research processes are scarcely developed in science news. On the contrary, aspects related to the results of scientific research are highly represented. Thirty-five news from the Clarin portal were analyzed between 01-01-2016 and 07-07-2017, using the constructed week methodology. As dimensions related to Processes were considered: epistemological, ethical, political and historical approach. Dimensions linked to Results were: epistemological optimism, utility, progress and spectacularity. It was also analyzed if news were signed by their author. Almost 83% of the news are biased towards Results and 83% of them are editorial. Almost 9 out of 10 news based on Processes are written by other agencies or signed. On the other hand, the opinion or interviews (n = 27), 67% are biased in favor of Processes. We propose that the incorporation into the news of dimens...

We studied the eects of methanolic extract (MEx) from the Prosopis torquata fruit on the reproductive functions, histology and morphology of the reproductive system of male Wistar rats. Ospring were randomly distributed in four groups. Three with a phytoestrogen-free diet and injected subcutaneously with MEx, estradiol (E) and vehicle (Ve), respectively. The fourth was fed with a commercial diet containing phytoestrogens (Cf + Ve). No signicant changes were observed in hormones values and in sperm concentration between the groups. The MEx group exhibited a slower testicle maturation, scarce number of elongated spermatids, and epithelial disorganization in the reproductive organs. Disruptive eect of MEx has been observed in our laboratory on female Wistar rats. Trabajo cientifico

All rights reserved Biological invasion is one of the main threats to native biodiversity. For a species to become invasive it must be voluntarily or involuntarily introduced by humans into a non-native habitat. Mammals were among first taxa to be introduced worldwide for game, meat and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in southeast USA) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g. Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly due to uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species C. aurita, C. flaviceps, C. geoffroyi, C. jacchus, C. kuhlii, C. penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions. Please cite this data paper when use the data in publications. We also request that researchers and teachers inform us on how they are using the data.

Birds have the ability to recognize such compounds and can avoid their intake, thus preventing adverse or toxic effects. The diet of Rufous-collared Sparrow (Zonotrichia capensis) in the Monte desert of Argentina indicates that this is a highly opportunist bird with broad diet breadth since it feeds on seeds, many of which contain phenolic secondary compounds. The aim of this study was to evaluate the feeding responses of Z. capensis against different kinds of individual compounds that are common in seeds. We conducted two-choice feeding trials in the laboratory in order to assess two different kinds of these compounds in seeds: complex phenols (high molecular weight) such as hydrolyzable tannin, tannic acid and condensed tannins; and simple phenols (low molecular weight) such as the phenylpropanoids: cinnamic acid, caffeic acid, and ferulic acid. In the trials we simultaneously pr...
