Animal production in pearl millet pasture under different nitrogen levels

O experimento foi conduzido em área da Universidade Federal de Santa Maria, RS, com o objetivo de verificar os efeitos de três níveis de adubação nitrogenada (0, 150 e 300 kg/ha de N) em pastagem de milheto (Pennisetum americanum (L.) Leeke) cv. Comum, sobre a produção animal. Foram utilizados novilhos de corte e avaliados o desempenho por animal, o número de animais.dia/ha e o ganho de peso vivo por área. O sistema de pastejo adotado foi o contínuo, com ajustes de carga para manter uma pressão de pastejo de 10%, caracterizando um resíduo médio de 3.168 kg de matéria seca/ha. As variáveis dependentes mostraram relação linear positiva com os níveis de adubação nitrogenada, o que denota o alto potencial do milheto.An experiment was conducted at the Universidade Federal de Santa Maria, in Santa Maria, RS, Brazil, with the objective of evaluating the effects of three N levels (0, 150 and 300 kg/ha), in pearl millet (Pennisetum americanum (L.) Leeke) cv. Comum, on animal production. Beef steers were assayed through daily liveweigh gain, gain per hectare and animals.day/hectare. A continuous grazing system was used, with stocking rate adjustments to maintain a 10% grazing pressure that characterized a medium residue of 3,168 kg of DM/ha. The dependent variables showed a positive linear relationship with the N levels, denoting the high animal production potential of pearl millet

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
