Impactos hidrometeóricos no alfa do Pantanal sul-mato-grossense/Brasil

O alfa do Pantanal sul–mato-grossense brasileiro vem sendo atingido por inundações sucessivas na década de 2010. O objetivo do trabalho foi analisar a espacialização dos impactos hidrometeóricos que ocorreram nos últimos sete anos nas sedes municipais de Aquidauana e Anastácio, com ênfase no episódio de 2011, para relacionar a função urbana estabelecida na área suscetível à inundação com a intensidade das inundações sazonais. A pesquisa fundamentou-se no entendimento das variáveis consideradas na área estudada, informações socioeconômicas e inventariação dos lotes. O trabalho de campo contou com um pré-mapeamento que consistiu no reconhecimento territorial e geomorfológico da área de estudo, e posteriormente a divisão das áreas suscetíveis à inundação em cinco setores, para descrição do perímetro urbano, foram analisados os Planos Diretores. Os resultados apontam a diminuição significativa do tempo de recorrência das inundações e revelam que a intensidade de magnitude das inundações está diretamente relacionada com os excessos pluviométricos na área da bacia hidrográfica do rio Aquidauana

GEOTECHNOLOGIES APPLIED TO MAPPING OF ENVIRONMENTAL FRAGILITY IN THE DESBARRANCADO RIVER BASIN, MS

This paper aims to analyze the degree of potential and environmental fragility of the Desbarrancado river basin. To develop this work remote sensing data were used and spatial analysis techniques in Geographic Information System and field survey. The results showed that the potential fragility of the watershed area of the Desbarrancado river consists of three categories: low, medium and strong, occupying 48.7%, 49.4% and 1.9% of the basin area, respectively. The environmental fragility revealed four categories: low, medium, high and very high, occupying 11.15%, 82.32%, 4.97% and 1.56% of the basin area, respectively. It is concluded that the watershed of the Desbarrancado river presents a prevalence low and medium degree potential fragility, however when considering the anthropic action has an enlargement of approximately 37% of the area occupied by the medium and high fragility and reduced in the same proportion of areas naturally low fragility, revealing that the predominance of cattle raising activities promoted significant changes in the balance ecodynamic are

Impactos hidrometeóricos no alfa do Pantanal sul-mato-grossense/Brasil

The alpha of the Brazilian Pantanal in south Mato Grosso has been hit by successive floods in the decade of 2010. The objective of this work was to analyse the spatialization of the climatic hazards that occurred in the last seven years in the municipal headquarters of Aquidauana and Anastácio, with emphasis on the episode of 2011, to relate the urban function established in the area prone to flooding with the intensity of the seasonal floods. The research was based on the understanding of the variables considered in the studied area, socioeconomic information and inventory of the land parcels. The field work had a pre-mapping that consisted of the territorial and geomorphological recognition of the study area, and later the division of the areas prone to flooding into five sectors. To describe the urban perimeter, Directors Plans were analysed. The results indicate a significant decrease in the recurrence time of the floods and show that the magnitude of the floods is directly related to the rainfall excess in the area of the Aquidauana river basin.O alfa do Pantanal sul–mato-grossense brasileiro vem sendo atingido por inundações sucessivas na década de 2010.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

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 nonnative 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 the southeast United States) 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 because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix 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.

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.
