Xenarthrans-anteaters, sloths, and armadillos-have essential functions for ecosystem maintenance, such as insect control nutrient cycling, playing key roles engineers. Because of habitat loss fragmentation, hunting pressure, conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 armadillos, 10 anteaters, 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7),...
Abstract Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential integrity landscapes where they occur. Carnivores also hold high conservation value their habitat requirements guide management plans. The order Carnivora has 84 species from 8 families the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; Ursidae. Herein, we include published unpublished data on native terrestrial (Canidae;...
Biological invasion is one of the main threats to native biodiversity. For a species become invasive, it must be voluntarily or involuntarily introduced by humans into nonnative habitat. Mammals were among first taxa worldwide for game, meat, and labor, yet number in Neotropics remains unknown. In this data set, we make available occurrence abundance on mammal that (1) transposed geographical barrier (2) Neotropics. Our set composed 73,738 historical current georeferenced records alien which...
Food quality and physiological capacities limitations in recognizing processing food are among the factors influencing choices of desert birds feeding. Seed-eating central Monte generally select grass seeds rather than forb seeds. We studied some mechanisms underlying seed-selection patterns seed-eating desert, analyzing nutrients secondary compounds 15 most abundant soil their relationship with diet six species birds. Grass contained more starch less total phenols did were free from...
Plant secondary metabolites (PSMs) can affect survival, reproduction, and distribution of herbivores. Individuals with a high capacity to tolerate PSMs will experience fewer smaller adverse effects than less tolerant individuals. Theoretically, the be acquired during development, modulated adulthood, or genetically fixed. We studied tolerance phenolic resin from creosote bush (Larrea tridentata) in two populations desert woodrats as first step understanding phenotypic habituation genetic...
Plant secondary compounds are deterrents and toxins to a variety of herbivores. The effect on water balance herbivores is virtually unexplored, yet many renowned for their diuretic effects in humans laboratory rats. We review data from the ethnopharmocological literature plants with effects. also present our experiments intake specialist (Neotoma stephensi) generalist woodrats (N. albigula) consuming plant natural diet. measured dietary voluntary consumption, urine volume osmolarity....
The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological sites throughout Brazil and its logic been applied in some other southern-hemisphere countries. supports aspects of necessary understand the processes that affect it. There are presently 161 sampling (see them at Supplementary Appendix), most which use a standardized methodology allows comparisons...
Sin Nombre virus (SNV), a hantavirus, can cause severe respiratory illness and death in humans. The primary carrier is the deer mouse, Peromyscus maniculatus, but other species of rodents may be infected with virus. We screened four woodrats (Neotoma) for hantavirus using both enzyme-linked immunosorbent assay (ELISA) polymerase chain reaction (PCR) tests. Woodrats were collected from variety habitats Arizona Utah. Only Neotoma lepida tested serologically positive an ELISA also contained SNV...
ABSTRACT The ability to cope with plant secondary compounds ( PSC s) has profound implications for an animal's behavior. In the present study, we assessed tolerance dietary phenolics in three seed‐eating birds: Z onotrichia capensis, S altatricula multicolor , and D iuca diuca which differ their diet breadth. Seeds habitat have distinct chemical composition: grass seeds less s, specifically, total than forb seeds. Based on detoxification limitation hypothesis using published data of natural...
The diet of mara (Dolichotis patagonum, Zimmeraman 1780) within the limits Sierra de las Quijadas National Park (San Luis, Argentina) is described.Other studies regarding mara's showed that mara, feeds on different species grasses and shrubs.However, there controversy proportions these items in or whether this proportion varies seasonally.Considering body size, anatomical features physiology, we suggest a greater than shrubs forbs.Moreover, giving region precipitation considerably between...
It is known that generalist herbivores may circumvent intoxication by ingesting small quantities from a mixture of plant secondary metabolites.However single chemical, highly toxic one or the most abundant in could cause toxicity.Survivorship and toxicity Rockland male mice were measured to determine if effects phenolic resin creosote bush (Larrea divaricata Cav.) due its major constituent, nordihydroguaiaretic acid (NDGA) total concentration compounds this resin.This objective was...

The aim of this study was to evaluate the meat quality double muscled Marchigiana young bulls characterized by different genotypes for hypertrophy: normal and mutated (heterozygous). Calpain calpastatin activities were determined verify state aging on a sample Longissimus thoracis muscle (XIII thoracic rib) taken at slaughtering (0h) after 24 hours (24h). After 14 days aging, another physical chemical parameters quality. results showed better animals respect animals. Another interesting...
We focused our study on the effects of Larrea cuneifolia phenolic resin leaf-cutting ants from two populations (Sierra de las Quijadas National Park and San Roque) Acromyrmex lobicornis in Luis, Argentina.We conducted bioassays food choice (fi eld laboratory) to compare ant workers these populations.Results fi experiment indicated that there were no differences preference for either leaves treated with or untreated among colonies both localities.However, results laboratory experiments...
Community structure is strongly influenced by positive interactions between species. Detecting and describing these essential in the study of communities. Dolichotis patagonum Zimmermann, 1780 (CN: mara) a cavid rodent that builds burrows for breeding. In this study, camera traps were used to identify which species use built maras Sierra de las Quijadas National Park, San Luis, Argentina. All other A total 68.7% all medium- small-sized taxa recorded burrows. This clear indicator role D. as...
