Item Comunidade de siris (crustacea: decapoda: portunidae) da zona de arrebentação da praia de Jaguaribe e estuário do Rio Jaguaribe, Ilha de Itamaracá, Pernambuco, Brasil(2022-06-03) Noé, Karyna Kelly Bezerra; Viana, Girlene Fábia Segundo; http://lattes.cnpq.br/3338076933519392Crustaceans are important members of tropical benthic communities, serving as food for humans. This study aimed to analyze the biometry, abundance and frequency of the population of Portunid crustaceans from Jaguaribe beach and Jaguaribe river estuary in Itamaracá-PE. The collections were carried out at three points: 1) the surf zone, 2) the river mouth and 3) the estuary. The crabs analyzed in this study are bycatch fish collected by trawling. Soon after collected, the crabs were packed in plastic bags and sent to the Bentos Laboratory (LABENTOS) at UFRPE/UAST. Individuals were identified, sexed and quantified. The data obtained were entered into an electronic spreadsheet for analysis of abundance, frequency and diversity. A total of 190 specimens were identified, distributed in five species: Callinectes danae (Smith, 1869), Callinectes ornatus (Ordway, 1863), Callinectes marginatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) and Charybdis hellerii (Milne Edwards, 1867). Regarding relative abundance, C.danae was considered a dominant species at all points, obtaining 54% at point 1, 66% at point 2 and 65% at point 3. Arenaeus cribrarius was considered abundant at point 1 with 35% and common at point 2 with 20%, it was not collected at point 3. Callinectes marginatus presented 28% at point 3, being considered common, at point 1 it was classified as occasional with 5%. C. ornatus showed abundance at points 1, 2 and 3 respectively with 5%, 9% and 7%, thus being classified as occasional. Charybdis hellerii was classified as occasional with 5%. In the frequency of occurrence, it was found that C. danae is a species considered euconstant with 82% of the collected sample. C. ornatus and C.marginatus, presented 45% each, thus being constant species. A. cribrarius presented 36% and is considered an accessory species. Considered accidental, C.hellerii with only 18% of the total sample. For diversity the values were low for the river mouth (point 2) and for the interior of the estuary (point 3), and low for the surf zone (point 1). The evenness values were equitable, J'= 0.7276 for the surf zone (point 1), J'= 0.691 for the river mouth (point 2) and J'=0.7555 for the interior of the estuary (point 3). Ancova analysis demonstrated a positive growth relationship between carapace width, carapace length, abdomen width, and weight. Differing only for Callinectes danae in relation to carapace width and abdomen width. The low abundance of Charybdis helleri shows that the species is not endangering native crabs in this locality. This study contributed to increase the knowledge about the crabs on the island of ItamaracáItem Performance do crescimento de mudas em diferentes estratégias de manejo como uma ação para recomposição e diversidade biológica de um ambiente em regeneração(2022-06-06) Souza, Marisa Adriana Gonçalves de; Souza, Luciana Sandra Bastos de; http://lattes.cnpq.br/1186468548787818; http://lattes.cnpq.br/0145072454700159In regions with a semi-arid climate, abiotic (ie, low rainfall, high incidence of factors, shallow and saline soils, nutritional deficit, etc.) recomposition of degraded areas, in addition to contributing to the increase of the biosphere and atmosphere. Currently, they cite the restoration of important work in process, using different management strategies. The adoption of practices aimed at restoring the environment becomes essential for maintaining environmental balance. Based on this, we analyzed the aspects of the effects of different management techniques on the biometrics of seedlings of five species, Anadenanthera colubrina (Angico branco), Cratylia argentea, (Camaratuba), Libidibia ferrea, (Pau ferro), Handroanthus impetiginosus (ipê – purple) ) and Sesbania bispinosa. The work is subdivided into two chapters: 1) Bibliographic review which was highlighted as the main adaptive strategies of plants of the bio caatinga format, as well as the use of different strategies used to recompose anthropized areas, and scientific 2) no. it comes from an experiment that sought to analyze the biometry and survival of the fauna of the caatinga in scientific initiation, with the purpose of enriching an area in a working state, aiming at the diversity of this environment. Therefore, an experiment was carried out between December 2021 and May 2022, at the Academic Unit of Serra Talhada (UAST/UFRPE). Seedlings of five species: Anadenanthera colubrina (Angico white). Cratylia argen, (Camaratuba)bidtea ferrea, Handroanthus impetiginosus (pei – purple) and Sesbania bispinosa were subjected to different management strategies: T1 = Control, T2= soil + hydrogel, T3= compost and T4= hydrogel + compost in an area of Caatinga in design. In average intervals of 8 days, the biometric knowledge parameters of the species were created: Height of the plant diameter (DC, mm), count of the number of leaves (NF) and the average of the canopy area (AC) ) (North - South; East - West). Data were selected for analysis of variance and comparison of means was performed using Tukey's test at a 5% probability level. What use of the hydrogel, organic compound + organic compound, we did not account for the variables among the variables. In this, the land use only aspect considered for better results and with the creation of low cost systems. The nucleation proved to be efficient for several biologicals in the environment and in this aspect, there was a better growth of angico followed by pau ferro.Item Análise da composição faunística de besouros rola-bosta (Coleoptera: Scarabaeidae: Scarabaeinae) em áreas de cerrado no estado do Mato Grosso(2022-05-26) Souza, Maria Beatriz Nunes de; Silva, Fernando Augusto Barbosa; http://lattes.cnpq.br/1447568762723987; http://lattes.cnpq.br/3605375135079871Dung beetles are detritivorous insects that feed mainly on feces and dead animals and also use them as a resource for nesting. They are widely distributed in the world and in Brazil and are extremely important as bioindicators, in biological control, in seed dispersal, nutrient cycling, aeration and soil hydration. Because they are sensitive to the environment, local changes such as loss of habitat and changes in microclimate can negatively impact their faunal composition, causing species decline and instability in the community and the environment. The objective of this work was to study the assemblage of beetles of the subfamily Scarabaeinae in different areas of the Cerrado that will be subjected to the direct and indirect influence of agricultural activities in the state of Mato Grosso due to the installation of an enterprise, characterizing the composition, richness and abundance of these beetles. beetles and comparatively analyzing these parameters between the studied areas. Two monitoring campaigns were carried out at the Aparecida da Serra farm, in the municipality of Tangará da Serra - MT, in March and July 2018. The beetles were collected at three points (P) distributed in the site corresponding to the areas that will be impacted when the enterprise is installed, representing the treatments: P1 = Area to be Directly Affected (ADA), P2 = Area of Direct Influence (AID) and P3 = Area of Indirect Influence (AII). For the collection, pitfall-type pitfall traps were used, which were distributed into two sampling units per point, placing three traps in each unit, totaling 18 traps per campaign. After 48 hours, the traps were removed from the field. The captured insects were placed in plastic bags containing 70% ethanol and taken to the laboratory for the routine procedures of sorting, drying and identifying the specimens. A total of 1,234 individuals were collected, distributed in 36 species and 14 genera. P1 had a significantly higher number of recorded species (25 species) among the analyzed treatments, while in P2 and P3 this number was similar, each with 13 species. The most representative species when all treatments and campaigns were analyzed together were Canthidium aff. barbacenicum, Onthophagus sp.2, Ontherus dentatus and Canthidium sp.2. There was a significant difference in the number of species recorded in the two campaigns between the treatments analyzed. There was no significant environmental disturbance when analyzing the species composition of the analyzed areas. Regarding the conservation value, the Area to be Directly Affected by the project (P1) presented a better conservation value, however the presence of Dichotomus paresi (considered a rare species) in the other areas (P2 and P3) increases the conservation value of these places , based on this, measures were suggested for better management and local conservation.Item Uso de microhabitat e atividade de forrageio de escorpiões da Caatinga, em função da luminosidade lunar(2018) Barros, Ana Maria Tavares de; Almeida, Cauê Guion de; http://lattes.cnpq.br/2072654463873094; http://lattes.cnpq.br/9772502563268635The Caatinga biome is one of the great natural regions of Brazil and is marked by its rich biodiversity. However, current research regarding this biodiversity is insufficient and, in the specific case of scorpion species, studies are especially needed. The present work investigates the foraging strategies of the scorpion speciesJaguajir rochae(Borelli, 1910), Bothriurus asperPocock, 1893, and Bothriurus rochaiMello-Leitão, 1932, within an area of the Caatinga, in order to analyze the possible occurrence of microhabitat overlap during foraging of these three species according to lunar luminosity and to determine the impact on foraging activity for Bothriurus asperor Bothriurus rochaidue to the abundance of Jaguajir rochae. Data was collected nocturnally in the Pollizadores Trail, in the municipalityof Serra Talhada, Pernambuco, between March and September of 2017. Scorpions were located utilizing an ultraviolet light and data was recorded for collection date, species, sex, exposure, microhabitat and activity. Statistical analysis was performed utilizing the program PAST, version 3.06. During 102 hours of field research, 262 total specimens were found with the research sample composed of 101 males,127 femalesand 34 unclassified juveniles. There was no correlation found between lunar luminosity and scorpion abundance, and nosignificant relation was found for microhabitat overlap and lunar luminosity and there was no abundance correlation found for bothriuridae and Jaguajir rochae.
