MarinEye - A tool for marine monitoring

This work presents an autonomous system for marine integrated physical-chemical and biological monitoring – the MarinEye system. It comprises a set of sensors providing diverse and relevant information for oceanic environment characterization and marine biology studies. It is constituted by a physicalchemical water properties sensor suite, a water filtration and sampling system for DNA collection, a plankton imaging system and biomass assessment acoustic system. The MarinEye system has onboard computational and logging capabilities allowing it either for autonomous operation or for integration in other marine observing systems (such as Observatories or robotic vehicles. It was designed in order to collect integrated multi-trophic monitoring data. The validation in operational environment on 3 marine observatories: RAIA, BerlengasWatch and Cascais on the coast of Portugal is also discussed.info:eu-repo/semantics/publishedVersio

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

In-feed macrolide Leucomycin (Leucomag 30% PR) for prevention of proliferative enteropathy in experimentally infected pigs Ração medicada com Leucomicina (Leucomag 30% PR) para prevenção da enteropatia proliferativa em leitões experimentalmente infectados

The aim of this study was to evaluate the efficacy of orally administered leucomycin at 90 and 180ppm for the prevention of porcine proliferative enteropathy (PPE) in experimentally infected pigs. A total of 90 commercial five-week-old pigs were randomly assigned to receive leucomycin in feeding at 90 (T2), 180ppm (T3), or untreated (T1). All animals in the treated groups received medicated feed for 14 days starting one day before inoculation. Each pig was inoculated intragastrically with approximately 4.5x10(9) Lawsonia intracellularis in the form of porcine intestinal mucosal homogenate. Body weight, feed consumption and clinic signs were evaluated throughout the study. Necropsies and gross evaluation of intestines were performed in all animals on day 23 post-inoculation (pi) or at death, and ileum samples were collected for immunohistochemistry (IHC) for L. intracellularis. Clinical presentation of the disease was more evident in the non-medicated group (T1) than in the medicated ones (T2, T3) between days 16 and 21pi. Average daily gain, average daily feed consumption and feed conversion efficiency were better in groups treated with either dose of leucomycin. The total intestine lesion length per group (T1, T2 and T3) was 869, 473 and 331cm, respectively. The majority of the animals (84.4%) were positive for L. intracellularis antigen in ileum sections stained by IHC. Under the conditions of this study, leucomycin administered in feed at 90 and 180ppm for 14 days was effective in improving performance of pigs inoculated with intestinal homogenate containing L. intracellularis.Este experimento foi realizado com o objetivo de testar a eficiência da leucomicina no controle da EPS. Para isso, utilizaram-se 90 leitões de cinco semanas de idade, provenientes de granja sem histórico clínico de EPS. Os animais foram divididos em três grupos (tratamentos) de 30, sendo T1 o grupo dos inoculados e não medicados, T2 e T3 os inoculados e medicados com 90ppm e 180ppm de leucomicina, respectivamente. No dia zero do experimento, os 90 suínos foram inoculados com aproximadamente 4,5x10(9) L. intracellularis. A medicação foi utilizada nas rações dos grupos T2 e T3 somente do dia anterior até 13 dias após a inoculação com L. intracellularis. Ganho de peso, consumo de ração e sinais clínicos foram avaliados durante todo o experimento. Todos os leitões foram eutanasiados 23 dias pós-inoculação (pi). Os sinais clínicos foram mais evidentes nos animais do grupo T1 que nos do T2 e do T3 entre os dias 16 e 21. Ganho de peso diário, consumo diário de ração e conversão alimentar foram melhores nos grupos medicados com leucomicina. A extensão total das lesões intestinais por grupo (T1, T2 e T3) foram de 869, 473 e 331cm, respectivamente. A maioria dos animais (84,4%) teve marcação positiva para L. intracellularis à IHC nas seções de íleo. Leucomicina nas doses de 90 e 180ppm por 14 dias foi eficiente para a melhora do desempenho de leitões inoculados com homogeneizado intestinal contendo L. intracellularis

Foliar diagnosis in citrus. II. Effect of cultivars and of leaf collecting quadrants on micronutrient amounts

Estudou-se o efeito da posição de coleta de folhas para análise química, em relação aos quadrantes, em quatro cultivares de citros. O experimento foi realizado em pomares comerciais da Fazenda Vitória, em Alfenas, MG, onde foram coletadas folhas de laranjeiras 'Pera Rio', 'Valência' e 'Baianinha' a da tangoreira 'Murcote', enxertadas sobre o limoeiro 'Cravo': Usou-se um delineamento experimental em blocos ao acaso, com quatro repetições. Os quadrantes de coleta de folhas compuseram as amostras, constituindo os seguintes tratamentos: Norte, Sul, Leste, Oeste, Norte e Sul, Leste e Oeste, e folhas coletadas nos quatro quadrantes (testemunha). Com relação aos quadrantes de amostragem foliar, a tangoreira 'Murcote' apresentou diferenças para os teores de B e Zn, enquanto as laranjeiras 'Pera Rio', 'Valência' e 'Baianinha' não apresentaram diferenças nos teores foliares dos micronutrientes analisados (B, Cu, Fe, Mn e Zn) em função dos quadrantes de amostragem foliar. Comparando os teores de micronutrientes entre as cultivares, a 'Baianinha' foi, de uma maneira geral, a que apresentou os maiores teores, seguida pela 'Valência', 'Pera Rio' e 'Murcote'.The effect of the position of the leaves on the tree, collected for chemical analysis, in relation to the quadrants in four citrus cultivars was studied. The experiment was conducted in commercial orchards at Vitória Farm in Alfenas, MG, Brazil, where the leaves were collected from 'Pera Rio', 'Valência', and 'Baianinha' orange trees and from 'Murcote' mandarin trees, grafted on 'Rangpur' lime rootstock. An experimental design consisting of randomized blocks with four replications was used. The leaf collecting quadrants made up the samples, forming the following treatments: North, South, East, West, North and South, East and West and leaves collected from four quadrants (test plot). With relation to leaf sampling quadrants, only the 'Murcote' mandarin tree presented variations in the B and Zn content, while the 'Pera Rio', 'Valência' and 'Baianinha' cultivars showed no differences in foliar content of the micronutrients analysed (B, Cu, Fe, Mn and Zn), as a result of the foliar sampling quadrants. Comparing the micronutrient content among the cultivars, 'Baianinha' was generally the one that showed the highest amounts, followed by 'Valência', 'Pera Rio' and 'Murcote'
