Item Caracterização estrutural do bosque de mangue urbano no rio Fragoso na Região Metropolitana do Recife, Pernambuco, Brasil(2025-08-08) Bandeira, João Pedro Serpa; Magalhães, Karine Matos; Coelho Júnior, Clemente; http://lattes.cnpq.br/1556412540089666; http://lattes.cnpq.br/1529606079794689; http://lattes.cnpq.br/8881102185822248Manguezal é um ecossistema localizado na zona costeira tropical e subtropical, o qual apresenta influência direta das marés, além de possuir características específicas como solo lodoso e plantas adaptadas a essas condições. São responsáveis por fornecer vários serviços ecossistêmicos, além de proporcionar condições essenciais para reprodução, alimentação e abrigo para os animais que circundam e vivem no manguezal. O estudo foi desenvolvido no remanescente de mangue localizado no rio Fragoso, município de Olinda-PE, onde ocorre uma pressão urbana iminente. Possui objetivo principal a caracterização estrutural do bosque a qual se enquadra a metodologia de parcelas, onde foram analisadas as variáveis: área basal, densidade de indivíduos/troncos e altura média e altura do dossel. No referido bosque de mangue do rio Fragoso foram registradas as espécies Avicennia schaueriana, Laguncularia racemosa e Rhizophora mangle. Referente ao quantitativo das espécies arbóreas, o bosque se apresentou como misto, mas com dominância de L. racemosa. Quanto às variáveis analisadas, árvores com DAP mostrou-se > 10 foram dominantes, caracterizando um bosque maduro, com área basal de 15,07 a 35,13 m2/ha, altura média do bosque de 6,5 a 8,2 m, altura média do dossel 7,74 a 13,04 m, densidade de indivíduos de 933,38 a 1700 por hectare, densidade de troncos entre 5250 a 5800,29 por hectare. Por fim, esses resultados indicam que o mangue é estruturalmente maduro, com boa regeneração, mesmo diante dos impactos.Item Uma análise histórica da mulher na agricultura familiar e sua relevância para preservação da biodiversidade genética e ecológica(2024-03-05) Silva, Jenifer Carla Borges da; Freitas, Nara Suzy Aguiar de; http://lattes.cnpq.br/6891650997818766; http://lattes.cnpq.br/0352343973672028Family farming, essential for food security and sustained by ancestral practices, is marked by the fundamental role of women in the conservation of genetic diversity and the cultivation of traditional varieties. These varieties are vital for the resilience of ecosystems against environmental challenges, but are threatened by modern agriculture and genetic erosion. Therefore, this research aims to analyze the female contribution to family farming and its impact on biodiversity conservation. Using a meta-analysis methodology, the research examines 60 scientific publications, including articles, dissertations, theses, and final papers, to identify trends and gaps in knowledge. Approximately 80% of the studies analyzed include specific information about gender, with 18% focusing specifically on women, reflecting the national reality of female participation in agriculture. Correlation analyses and chi-square tests were applied to investigate the relationship between gender and the use of agrochemicals and organic practices, finding no statistically significant associations. Multiple Correspondence Analysis (MCA) was employed to explore the relationships between seed varieties, methods of acquisition, and geographical locations of farming families in Brazil. The results reveal systemic barriers faced by female farmers, such as limited access to financial resources and agricultural credit. The study also highlights seed selection based on immediate characteristics, the cultural importance of seeds, and the need for supportive policies for family farming. A crucial aspect is the ongoing genetic segregation of Creole seeds, which allows them to adapt to environmental changes and resistance to pests and diseases, although it may result in inconsistencies in production. The artificial selection of Creole seeds by farmers can lead to the loss of valuable genes, underscoring the urgency of expanding the presence of specialized technicians. Family farming in Brazil is revealed in a complex manner, influenced by historical, cultural, and environmental factors.Item Contribuições ao estudo da história natural da suaçuboia Corallus hortulana (Serpentes: Boidae), em uma unidade de conservação na Floresta Atlântica de Pernambuco, Nordeste do Brasil(2022-05-27) Santos, Maria Laura Silva; Santos, Ednilza Maranhão dos; http://lattes.cnpq.br/5812920432455297; http://lattes.cnpq.br/2606618267580412Studies on the natural history of species form the basis of knowledge about biodiversity, brings information on the population structure, sexual maturation, sexual reason, fecundity and habitat use. The project aimed to obtain information on the natural history of C. hortulana in a fragment of Atlantic Forest in the Parque Estadual de Dois Irmãos (PEDI), a Conservation Unit. Data collections occurred from October 2015 to July 2017 bimonthly and from April 2019 to September 2021 monthly, with active research, using time-limited viewing, occasional encounter, and third-parties collection. After collection, morphometry was performed, marking and release of the animal. 29 individuals of C. hortulana were recorded over the 50-month period, 18 females and 10 males and an unspecified individual. The specimens were found in three substrate types: buildings (54.29%) vegetation (28.57%) and soil (17.14%). Individuals above 1200 mm foraged in buildings, larger animals (1400 mm) were observed on the soil substrate and different sizes (1040 mm a 1811 mm) in the vegetation. Of the 31 encounters with active animals, 19 were found during the morning, nine in the afternoon and three at night, this may point us to the point that perhaps the species is not exclusively active in the night shift. A fight between two males has been documented, the record of male body fighting and the recapture of one of these individuals in copulation, as well as the observation of animals found and recaptured in the same locality may indicate to territoriality. There were seven animals recapture. A copulation and a court were recorded. PEDI has the potential for more studies to be developed with Corallus hortulana, there are few researches on its natural history and information like this is of great value for the conservation of the species and its habitat, a long- term study may allow more gaps to be filled in about your life history.
