A articulação femorotibial é uma articulação complexa do tipo sinovial, que, além da relação com a patela, em algumas espécies de animais pode apresentar uma estrutura radiopaca visualizada ao exame radiográfico de formato oval entre os ossos do fêmur e tíbia, em projeção mediolateral, denominado ossículo meniscal. Embora comumente relatado em diferentes espécies, inclusive no homem, pouco se sabe sobre a sua função e frequência, sendo bem constatada sua existência em espécimes de grandes felídeos. O presente estudo teve como objetivo realizar a análise radiográfica da articulação femorotibiopatelar de 40 gatos-domésticos (Felis catus, Linnaeus, 1758) em projeções mediolateral e craniocaudal no intuito de avaliar a presença ou ausência do ossículo meniscal. Nas radiografias realizadas, o ossículo esteve presente em 15% (n = 6), observando-se sua maior frequência em machos e unilateralmente, sendo o joelho esquerdo o de maior incidência da estrutura. Por ser um achado comum e relatado em diversas espécies selvagens de felídeos, a presença do ossículo meniscal deve ser levada em consideração e inserida como diagnóstico diferencial quando da realização de radiografias de gatos-domésticos e da visualização de opacidade intra-articular em projeções radiográficas mediolaterais da articulação femorotibiopatelar.

The aim of the present study was to determine the behavior of physicochemical characteristics of feijoa fruits of seven genotypes grown in two locations of Santa Catarina. The evaluation was made using the following: (i) 2011/12, 2014/15 and 2015/16 harvests of genotypes 85, 101, 223, 458 and 509, cultivated in Fraiburgo (Papua community); and (ii) 2014/15 and 2015/16 harvests of genotypes 28.12 and 527, in Agua Doce (Vista Alegre community). Diameter (cm), length (cm) and weight (g) of the fruit, peel (g) and pulp (g) weight, peel thickness (mm), and total soluble solids (Brix grade) were evaluated. An analysis of variance, comparisons between means using Tukey’s test (p < 0.05), and Pearson correlation coefficients (p < 0.05) were computed for the variables of feijoa fruits. In Agua Doce, genotype 527 had the largest diameter and weight of the fruit (88.7 g). In Fraiburgo, genotype 85 had the highest fruit weight (94.9 g) and genotype 509 had the highest pulp yield (37.5%). Not all genotypes with higher fruit weight exhibited higher pulp yield, confirming that the skin thickness and fruit size variables are directly related to yield. The variation in total soluble solids values was due to the environment and genotype effects.

Plant extracts have secondary metabolites that can act as bioherbicides, with the advantage of being more environmentally friendly. Mikania laevigata belongs to the family Asteraceae and has coumarin 1,2-benzopyrone as a chemical marker, which is capable of inhibiting or stimulating the germination and growth of adjacent plants. Thus, the objective of this work was to evaluate the phytotoxicity of aqueous and ethanolic extracts of M. laevigata on Lactuca sativa (lettuce) and Bidens pilosa (beggarticks). Five concentrations (0.1, 1.0, 1.5, 2.0 and 3.0 mg.mL-1) of aqueous and ethanolic extracts were tested in separate experiments, with distilled water as the control. Germination percentage, germination speed index, initial growth and the content of hydrogen peroxide (H2O2) and malonaldehyde (MDA) were evaluated. In the presence of the ethanolic extract, germination of the species (lettuce and beggarticks) was reduced by 85% and 90%, respectively. Radicle length, for the lowest concentration of the extracts, was not affected. However, at a concentration of 2.0 mg.mL-1 the reductions were 85% for lettuce and 65% for beggarticks. The increase of H2O2 content depended on the dose, where the greater the concentration of the extracts, the greater the production of peroxide, followed by an increase in MDA for lettuce and beggarticks. Seedlings grown in a concentration of 3.0 mg.mL-1 of the ethanolic extract were subjected to necrosis, making subsequent analyses impossible. The M. laeviagata extracts at concentrations of 2.0 and 3.0 mg.mL-1 demonstrated phytotoxicity, with increased oxidative stress in lettuce and beggarticks.

Eucalyptus urophylla S. T. Blake e uma das principais especies de eucaliptos cultivadas. Entretanto, nao existem recomendacoes para o teste padrao de germinacao de E. urophylla . Assim, o objetivo foi determinar a melhor metodologia para a conducao do teste de germinacao de sementes de E. urophylla . O experimento foi dividido em duas etapas. Na primeira, foram testados dois substratos (sobre papel mata-borrao e areia) e seis temperaturas (constantes de 15, 20, 25, 30, 35oC e alternada de 20-30oC, entre noite e dia, respectivamente) na conducao do teste de germinacao. Na segunda etapa, foi selecionado o substrato mais indicado no experimento anterior e testado em dois lotes, nas seis temperaturas citadas anteriormente. Foram avaliadas a germinacao, primeira contagem, indice de velocidade e tempo medio de germinacao. O experimento foi realizado em delineamento inteiramente casualizado com quatro repeticoes e os tratamentos foram dispostos em esquema fatorial de 2 x 6 para ambas as etapas. Na comparacao da germinacao entre os lotes, observou-se que o lote 1 apresentou menor desempenho do que o lote 2 nas condicoes de temperaturas extremas. O teste de germinacao de sementes de E. urophylla deve ser realizado a 30 ou 35°C com semeadura sobre papel ou areia, e com contagem inicial e final aos quatro e 10 dias apos a semeadura, respectivamente. Com base nesta pesquisa, mais testes podem ser realizados, para outros lotes e sementes de E. urophylla de outras procedencias, para garantir a confirmacao dos resultados.

Comunidades dependentes de recursos pesqueiros combinam informações acerca do comportamento da ictiofauna com características oceanográficas e interações ecológicas. Esse conhecimento é definido como tradicional: um complexo entre conhecimento histórico, prático e crenças, os quais evoluem por processos adaptativos e são transmitidos através das gerações. No litoral norte do Rio Grande do Sul, uma comunidade estabelecida nas margens do Rio Tramandaí realiza pesca de emalhe. A interação com animais marinhos ocorre em todas as artes de pesca na região, e a captura incidental de aves marinhas é registrada no sul do país. Predadoras de topo, as aves interagem com barcos pesqueiros em busca de alimento. O objetivo do presente estudo é explorar o conhecimento dos pescadores sobre as aves marinhas. Doze pescadores de Imbé foram entrevistados. Nas narrativas escritas, utilizou-se a análise de discurso. Os pescadores identificam as espécies de aves e as relacionam ao ambiente, reconhecem seus ciclos de vida, e utilizam seus comportamentos para localizar o recurso pesqueiro e obter dados oceanográficos e meteorológicos para aprimorar a navegação. Dessa forma, verificou-se que o conhecimento sobre as aves é uma variável para a orientação no oceano e para a realização de uma pesca efetiva.

This study aimed to investigate the population biology of Minuca mordax in the Igaracu River, Parnaiba, analyzing frequency distribution in size classes, reproductive period, relative growth, morphological sexual maturity, sex ratio and heterochely. The crabs were manually collected, randomly, by two people for 1 hour, in the representative months of the dry season (September to November) and rainy (April to June). In laboratory the crabs were identified, separated according to sex and measured. A total of 610 samples were captured, with 453 males and 157 females. The average size of carapace width (CW) was significantly different (p < 0.05) between males (17.21 ± 3.68 mm) and females (15.06 ± 3.18 mm). The distribution of the crabs in size classes was unimodal for both sexes. The morphological sexual maturity obtained for males was 12.42 mm CW and females was 10.05 mm CW. The sex ratio for the population was 1:0.35 (male: female), with significant difference from the expected ratio of 1:1. The heterochely was observed only in males of the species (224 right-handed and 229 sinister). Subsequently, other on-site observations were carried out monthly, from February/2011 to January/2012 to observe ovigerous females and determine the reproductive period. Females with eggs were observed only from March to June, corresponding to the rainy season in the region. The results found in the present study are similar to those observed in other populations of violinist crabs and suggest that the population is stable in the environment. The present study provides subsidies for the conservation of the species in the Igaracu River.

Due to the tomato growing socioeconomic importance, issues about the germination and the vegetative growth of the species are the aim of studies focusing on its improvement, seeking mostly to increase productivity. Therefore, this work aimed to evaluate the influence of the gibberellic acid and different levels of shading in the germination and initial development of tomato seedlings from the Super Marmande variety. The experimental outline adopted was in randomized blocks, arranged in factorial scheme (2x3), managing the factor A with and without the application of the hormone, Gibberellin (GA), at a concentration of 200 mg.L-1, and the factor B in three different levels of luminous intensity (full sun (0%), 70 and 90% shading). The germination and the conduction of the experiment were carried out in polyethylene trays with commercial substrate Terral®, composed of 20 plants with 10 repetitions each and the evaluations were carried out 26 days after sowing (DAS). Analysis were led on germination rate, germination speed index, germination percentage, fresh mass, fresh mass, total dry biomass, root volume, stem diameter, root length, the height of aerial part and photosynthetic pigment. Results pointed out that only the levels of shading affected the germination. The application of gibberellic acid for the Super Marmande tomato did not reveal a significant effect. The development of seedlings in the shading of 70% and 90% was better when compared to the full sun treatment.

This work reports data about the reproductive dynamics, dietary pattern and associations with parasites of Artibeus lituratus specimens captured from 2009 to 2018 in three urban natural parks in the municipality of Rio de Janeiro. The animals were captured with mist nets, measured, weighed and inspected for ectoparasites; whenever possible, feces were collected and blood smears prepared for dietary analysis and presence of hemoparasites, respectively. Based on an evaluation of 307 captured specimens, the biometric data were within the expected for the species. Diet was evaluated from 68 fecal samples, which contained insect fragments, and fruit pulp and seeds of Urticaceae, Combretaceae, Myrtaceae, Piperaceae, and Solanaceae. The parasites found in association with the bats were the Diptera Paratrichobius longicrus and the mite Periglischrus iheringi, in addition to the hemoparasites Plasmodium sp., Hepatozoon sp., and Litomosoides sp. Data about the reproduction of A. lituratus in these urban parks show that this species maintains a reproductive pattern typical of Stenodermatinae, which consists of bimodal polyestry with peaks in March and April and in July, August and September.

The retromolar foramen and retromolar canal as well are anatomical variations of the mandible that occur in the region of the retromolar trigone. This foramen and canal contain neurovascular structures that provide additional innervation to the lower molars and buccal area. This study aimed to determine the incidence and occurrence between the sexes of the retromolar foramen in mandibles of the Contemporary Bone Collection of the Federal University of Pernambuco. Sixty-one dry mandibles were analyzed, 37 from males and 24 from females. Of the 61 mandibles, 18 had retromolar foramina (29.5%), and 12 had a unilateral foramen (19.67%). Male mandibles had a higher incidence compared to female bones, with 12 (32.43%) mandibles with retromandibular foramina. The population analyzed showed a high incidence of the retromolar foramen, especially on the right side. The identification of this anatomical variation helps in the planning of oral surgeries and during anesthetic procedures.

Prosopis juliflora (Sx.) DC., commonly known as algarroba, is an adapted tree species in Brazil with animal food value and environmental value in reforestation. However, little is known about its molecular genetic diversity. Therefore, the aim of our study was to use different similarity measures based on the genetic characterization of algarroba obtained through ISSR and RGA markers in naturalized individuals in southwestern Bahia. Young leaves of 36 algarroba individuals were collected in the municipality of Itapetinga, Bahia. DNA was extracted by the 10% SDS protocol and quantified by the absorbance ratio A260/A230 and A260/A280 nm. Ten pairs of RGA and 23 primers of ISSR were used for PCR, and the amplified products were electrophoresed on 2% agarose gels for 2 h. The genotyping results (binary matrix) were used to calculate the Jaccard, Simple Matching and Sorensen Dice similarity coefficients. Finally the UPGMA clustering, Tocher optimization and PCA were performed. We observed for ISSR and RGA 205 and 68 marks, respectively, with expected heterozygosity of 0.28 and 0.21; polymorphic information content was 91.71 and 0.17% and genetic distance 8.0 and 8.53, respectively. These findings contribute to our understanding of the wide distribution and adaptation of this species in reforested areas.
