Item Análise das condições da comercialização de crustáceos e moluscos nos principais mercados públicos do Recife(2025-02-27) Silva, Lucas Felix da; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086The sale of crustaceans and molluscs in Recife's public markets plays a fundamental role in the local economy, especially considering the city's strategic position as one of the main fishing centers in northeastern Brazil. These products are widely consumed by the population and, in addition to their gastronomic importance, represent a significant source of income for fishermen and traders in the region. However, the sale of these foods in public markets faces specific challenges related to the preservation of quality and food safety, requiring some special attention to handling practices and hygienic conditions. The lack of hygienic standardization, infrastructure and supervision in these markets can cause several problems for consumers. Therefore, this work aims to observe and analyze the conditions of fish marketing, mainly crustaceans and molluscs in the main public markets in Recife.Item Acompanhamento atividades de pesquisas em biologia reprodutiva Anisotremus surinamensis (Bloch, 1791) capturado no litoral norte de Pernambuco, Brasil(2021-07-16) Leite, Rafael Barros; Oliveira, Paulo Guilherme Vasconcelos de; http://lattes.cnpq.br/5700488412022830; http://lattes.cnpq.br/3233322973038222Item Armazenamento pós-colheita da palma forrageira afeta o índice de apodrecimento e a composição química dos cladódios?(2024-09-18) Felix, Thamyres Priscylla Silva de Oliveira; Santos, Mércia Virginia Ferreira dos; Silva, Natália Viana da; http://lattes.cnpq.br/0190091649509674; http://lattes.cnpq.br/9565465836878202; http://lattes.cnpq.br/4093484221298909Item 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 Desenvolvendo um protocolo de cultivo ex situ de corais brasileiros: um estudo piloto(2022-10-07) Silva, Tarciso Roberto Sena da; Cordeiro, Ralf Tarciso Silva; http://lattes.cnpq.br/7228145091477218; http://lattes.cnpq.br/4451949933618921Biological reefs are among the most important and, yet, threatened ecosystems nowadays, having corals as major structurer organisms. The Brazilian coral fauna, specifically, faces the impacts of global climate changes, showing bleaching events each time more severe and frequent. Although species conservation in situ must be the priority of legal and institutional efforts, natural ecosystem reduction has compromised the efficiency of those strategies. Due to the lack of protocols aiming at the management and maintenance of Brazilian hydrocorals, the present study was dedicated to the formulation of methodologies aiming the husbandry of national organisms on ex situ systems, that pottentialy would reduce the nonsuccess, due to independence of ambiental factors causes of the increase in mortality. The study started with a bibliographic survey, reviewing the available pertinent literature, which, mostly, is aimed at organisms from known oligotrophic ambients of the Indo-Pacific ocean. Aimed at the husbandry of ornamental marine organisms. From that, it was tested an adaptation of protocols to simulate ambient conditions from coastal Brazilian reefs (mesotrophic). Then, it was collected samples of coral Millepora alcicornis, common in northeast Brazilian reefs, candidates to model organisms for ecological studies on closed systems. The selected organisms were manually obtained by free diving in the localities of Porto de Galinhas (Ipojuuca - PE). After collection, the organisms were conditioned, transported, and acclimated to the Laboratório de Invertebrados Marinhos of Universidade Federal Rural de Pernambuco. Concurrently, the essays were aimed to the test of nutritional protocol, then the health and response to the food stimulus were monitored; as well as measured abiotic factors, essential to a good working system. In the study, the animals had a positive development and adaptation, shown in the polyp expansion and growth during the experimentation. The obtained results indicate that system and protocol, yet in the initial development phase, have met the nutritional and metabolic demands of Millepora alcicornis, and could result in an alternative to studies and strategies of conservation in closed systems.Item Acessando a resiliência na Área de Proteção Ambiental Costa dos Corais (Nordeste do Brasil) para embasar decisões de manejo(2018-08-27) Silva, Thaysa Carla Gomes da; Gomes, Paula Braga; http://lattes.cnpq.br/3289333472399959; http://lattes.cnpq.br/2654152836966384Coral reefs are mainly characterized by having one of Earth's greatest biodiversity, as well as being recognized for the provision of vast goods and services. In Brazil, the reefs are distributed over 3,000km along the coast of the country, representing the only reef system in the South Atlantic and being affected by several threats due to the rapid development of coastal areas and high exploitation of its resources. Recognizing when coral reefs are becoming critically fragile is a major challenge, and therefore resilience measures have been considered a strategy to avoid degradation. For this reason, some studies have been developing methodologies using several factors to indicate and calculate reef resilience in order to develop management and conservation strategies. Therefore, it is relevant to study the resilience of coral reefs in Brazil based on their use in order to improve management and monitoring, promoting the reduction of ecosystem degradation and influencing the choice of priority areas for conservation. Along Costa dos Corais Environmental Protection Area, there are several reefs with different intensities of use, including areas of exclusion of use and areas of high intensity of tourist use. In this way, the site allows to analyze the resilience from the comparative point of view between different reef sectors, under their different situations of use and conservation and relating their degree of resilience with the indicators. For this purpose, the resilience factors were selected based on the literature and all indicators were posed as questions. The questions were applied to APACC’s Council to analyze these parameters in APACC’s 21 reefs, about the following sites: Tamandaré (4 reefs), São José da Coroa Grande (3), Maragogi (4), Japaratinga (3), Porto de Pedras (3) and São Miguel dos Milagres (4). The reefs reached a score of 41 for lowest resilience (São Miguel dos Milagres) up to 71 for highest resilience (Maragogi). According to the ranking, the reefs that obtained high (> 62), medium (between 52 and 60) and low resilience (< 51) were identified. The location with the highest amount of reefs with high resilience is in Japaratinga, while the lowest site is in São Miguel dos Milagres. It is also possible to observe that the reefs that obtained higher scores are located in areas restricted to the use, while those that are present in Visitation Zones obtained lower scores, representing about 66% of the reefs considered with low resilience. With the exception of Piscina de São Miguel dos Milagres, all Marine Life Protection Zones were considered areas of high resilience. Overall, our results show that the management of APA Costa dos Corais has been successful in selecting closed areas, since they have high resilience, with the exception of the only Marine Protection Zone in São Miguel dos Milagres. However, some indicators of resilience can be improved with management actions.Item Diagnóstico da arborização urbana provenientes de solicitações de poda e/ou supressão em unidades operacionais da COMPESA(2021-12-10) Santos, João Pedro Mesquita Souza; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/9510283556240839The operational units of Companhia Pernambucana de Saneamento (Compesa) do not carry an afforestation plan, nor a systematic diagnosis of this private urban forest. Due to this problem, this study aimed to carry out a floristic survey and qualiquantitative diagnosis of trees, which sought to identify the problems related to planting and interference with the structures and / or equipment of the units located in the Metropolitan Region of Recife - Pernambuco. The identification of these trees, carried out by pruning and/or deletion, resulted in the categorization of 82 individuals into 19 species, distributed in 11 botanical families. The most frequent species was Mangifera indica L., with 23 specimens, representing 32.92% of the sample. The Anacardiaceae family was the most present, consisting of Mangifera indica L. (74%), Anacardiumoccidentale (19%) and Spondiasmombin (7%). Most of the identified plants are exotic (65.85%) and fruitful (68.29%). Of the total 93.9% presented the need for corrective actions such as pruning, and 6.1% were cases of suppression. In case reports, mangifera indica L. (29.87%) was the most frequent species. Among the dendrometric variables analyzed, mean values of DBH and H were obtained, where it was found that 76.82% of the trees are medium-sized and all in the adult stage. The qualitative aspects of the front afforestation were: Upwelling of the roots above the ground (32.92%); crown balance (balanced crown - 63.41% and partially balanced - 36.58%), with no representation of trees with unbalanced crown; presence of termites (51.22% not observed and 48.78% observed); need only for maintenance such as pruning (57.32%) and conflicts with structures and/or equipment (42.68%). The Conditions of conflict include: 60% interfere with the electrical network and 40% conflict with other structures and/or equipment. These results point to the need of a strategic planning for the maintenance and conservation of the urban forest present in the company's units.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.
