ANÁLISE DA DIETA DE LUTJANUS SYNAGRIS(LINNAEUS, 1758) NA BAÍA DE TODOS OS SANTOS

A família Lutjanidae contém 125 espécies dentro de 21 gêneros,cinco subfamílias e são considerados recursos pesqueiros em toda a sua distribuição geográfica (NELSON, 2006; RANDALL, 1996; LINDEMAN, et al., 1998). Os lutjanídeos ocorrem em todos os oceanos e em regiões de águas tropicais e subtropicais, são peixes marinhos demersais que tem seu habitat em recifes de coral e áreas fora da plataforma continental(LIESKE, E. AND R. MYERS, 1994).A espécie estudada nesse projeto é o Lutjanus synagris (Linnaeus, 1758), cujo nome popular é Vermelho em algumas regiões da Bahia, porém também pode ser encontrado com o nome de Ariocó ou Dentão. Sua distribuição geográfica vai desde a costa Leste dos Estados Unidos e se estende até o Sudeste do Brasil. Estes peixes também podem ser encontrados em águas salobras escuras e sobre fundos de lama (RANDALL, 1967). Os indivíduos adultos conseguem alcançar maiores profundidades, até 650m, e podem atingir 60cm de comprimento (IGFA, 2001). Sua alimentação consiste basicamente de crustáceos e outras espécies de peixes, e seu hábito alimentar é noturno (ALLEN, 1985).Esta presente trabalho teve como objetivo analisar a dieta de Lutjanus synagris, abordando aspectos como preferência alimentar e suas variações sazonais

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 Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae).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

Clinical and genetic characteristics of late-onset Huntington's disease

Background: The frequency of late-onset Huntington's disease (>59 years) is assumed to be low and the clinical course milder. However, previous literature on late-onset disease is scarce and inconclusive. Objective: Our aim is to study clinical characteristics of late-onset compared to common-onset HD patients in a large cohort of HD patients from the Registry database. Methods: Participants with late- and common-onset (30–50 years)were compared for first clinical symptoms, disease progression, CAG repeat size and family history. Participants with a missing CAG repeat size, a repeat size of ≤35 or a UHDRS motor score of ≤5 were excluded. Results: Of 6007 eligible participants, 687 had late-onset (11.4%) and 3216 (53.5%) common-onset HD. Late-onset (n = 577) had significantly more gait and balance problems as first symptom compared to common-onset (n = 2408) (P <.001). Overall motor and cognitive performance (P <.001) were worse, however only disease motor progression was slower (coefficient, −0.58; SE 0.16; P <.001) compared to the common-onset group. Repeat size was significantly lower in the late-onset (n = 40.8; SD 1.6) compared to common-onset (n = 44.4; SD 2.8) (P <.001). Fewer late-onset patients (n = 451) had a positive family history compared to common-onset (n = 2940) (P <.001). Conclusions: Late-onset patients present more frequently with gait and balance problems as first symptom, and disease progression is not milder compared to common-onset HD patients apart from motor progression. The family history is likely to be negative, which might make diagnosing HD more difficult in this population. However, the balance and gait problems might be helpful in diagnosing HD in elderly patients
