Título: Efeitos das atividades antrópicas sobre populações de caranguejos-fantasmas Ocypode quadrata (fabricius, 1787) em praias arenosas da costa cearense Autor(es): Lima, Jadson Pinto de Abstract: This study evaluated the influence of urbanization and fixed tourist infrastructure (beach shacks) on populations of the ghost crab Ocypode quadrata on sandy beaches of Brazil's semiarid coast. Two complementary approaches were conducted. In Chapter 1, five beaches with varying levels of urban development were assessed using morphological data, anthropogenic impact indicators, and ghost crab population parameters (burrow density and diameter). Despite differences in urbanization, no significant variation in burrow density or diameter was observed, except between Sabiaguaba and Canto Verde beaches. In Chapter 2, intra-beach variation was examined at Praia do Futuro by comparing areas with and without beach shacks. While overall burrow density did not differ, spatial redistribution and significantly larger burrow diameters were found in shack areas, likely reflecting increased food availability. These findings suggest that although burrow density alone may be a limited bioindicator, burrow diameter and spatial distribution reflect adaptive responses to anthropogenic pressures and may support more effective coastal management strategies.

Título: O encontro da terra e do mar: Flora e Biogeografia da vegetação sobre restingas do litoral brasileiro Autor(es): Gouveia, Luciana de Freitas Patriota Abstract: Restingas are geologically recent ecosystems found along the coast on sandy coastal barriers. In Brazil, they are characteristic sandy coastal ecosystems and are considered communities integrated into the Atlantic Forest Biogeographic Domain. Restingas exhibit varied phytophysiognomies that generally fall into three basic vegetation types: grassland, shrubland, and forest. Despite the growing body of scientific literature on the flora of Brazilian restingas, a lack of systematization regarding this knowledge remains evident. To address this gap, we compiled scientific publications from virtual libraries with the aim of: 1) Accessing available knowledge regarding the floristics and phytosociology of Brazilian restingas; 2) Producing a catalog of plant species found in Brazilian restingas based on floristic lists, in order to document scientific names and report the most common species; 3) Generating and making available to the scientific community a database of occurrence records for plant species in Brazilian restingas; and 4) Understanding the floristic relationships among Brazilian restingas and with adjacent biogeographic domains. To achieve these objectives, we organized the research for this thesis into four chapters. The results indicated that the majority of scientific publications stem from studies conducted in the Northeast and Southeast regions of Brazil and that the five botanical families with the highest species richness in restinga ecosystems are Fabaceae, Myrtaceae, Poaceae, Asteraceae, and Rubiaceae. We found that phytosociological studies lacked a standardized sampling methodology, likely due to the complexity of restinga environments. In the Catalog of Restinga Species, we compiled 3960 phanerogam species, 1143 genera and 186 botanical families. We also created the SANBRA (Sandy Coastal Ecosystems of Brazil) database, featuring a sample of over 100 coastal locations in Brazil. This database represents the flora found in published floristic and phytosociological lists regarding Brazilian restingas, covering all restinga phytophysiognomies. SANBRA compiles over 18.000 plant records from Brazil's restinga ecosystems, with the most frequently occurring species being Anacardium occidentale, Guapira opposita, Eugenia punicifolia, Tapirira guianensis and Ipomoea pes-caprae. As for Phytogeography, we observe a diverse Brazilian restinga ecosystem, characterized by regional particularities and a distinct floristic identity. Furthermore, we note a significant floristic influence from the Atlantic Forest on the species composition of restingas. Finally, we highlight the need for further research on restingas, particularly in light of increasing human impact on Brazil's coastal regions. Tipo: Tese

Título: Eficácia da gestão de áreas protegidas frente à proteção de recursos hídricos: estudo em unidades de conservação no litoral cearense Autor(es): Sousa, Kelven Pinheiro de Abstract: The state of Ceará presents a coastline with an extension of 626.89 km, with about 30 Protected Areas (PA) distributed throughout its coastal zone (terrestrial and maritime), featuring diverse environmental and social issues. Given this reality, this study aims to evaluate the effectiveness of the conservation of water resources, and their associated environmental assets, safeguarded in coastal PAs of Ceará. The researched area focuses on 7 PAs present in 2 sectors of the Ceará Coastal Plain (Fortaleza/Metropolitan Region and West Coast), which overlap with 2 hydrographic regions (Metropolitan and Curu), they are: Paracuru Dunes Environmental Protection Area, Curu River Estuary Environmental Protection Area, Ceará River Estuary Environmental Protection Area, Pacoti River Environmental Protection Area, Ceará Botanical State Park, Sítio Curió Area of Relevant Ecological Interest, and Batoque Extractive Reserve.. The study, of an exploratory and descriptive nature, was developed in three complementary stages: (i) systematic literature review on water conservation in protected areas; (ii) environmental and territorial diagnosis of the analyzed units; and (iii) integrated analytical stage, involving participatory methodologies, analysis of institutional perception, and evaluation of public policies by the Theory of Change (ToC) method, culminating in the proposal of the Water Status Index of Protected Areas (IEH-PA). Article I demonstrates the relevance of protected areas as a primary strategy for safeguarding ecosystems and water resources across the diverse territories observed. Article II establishes the issue of 'limitations' as the focal point of environmental conflicts/impacts and the ecological functions of the evaluated protected areas; it further demonstrates that the mere existence of these areas does not guarantee adequate environmental protection, thus requiring the active and permanent engagement of diverse stakeholders. Article III aligns the perspectives of managers and social actors within the evaluated territories, who acknowledge the importance of water conservation while identifying vulnerabilities in environmental monitoring, institutional coordination, and the need for broader social participation and inter-institutional partnerships. These factors collectively informed the development of the IEH-UC proposal, which aims to support the environmental monitoring of water resources within PA. Tipo: Tese

Título: Valoração ambiental do ecossistema manguezal no Ceará: contribuições dos serviços ecossistêmicos nas políticas públicas Autor(es): Freitas, Anderson Nonato de Abstract: Mangroves play a relevant role in the provision of ecosystem services, including shoreline protection, biodiversity conservation, regulation of ecological processes, and support for socioeconomic activities. Despite their importance, these ecosystems have been subjected to continuous degradation processes associated with urban expansion, aquaculture, anthropogenic activities, and changes in land use and land cover. In this context, the economic valuation of ecosystem services is configured as a planning instrument capable of expressing, in monetary terms, the benefits generated by mangroves, contributing to comparative analyses within the scope of the formulation and evaluation of public policies. This study aimed to carry out the environmental valuation of ecosystem services provided by mangrove forests in the State of Ceará and to analyze how these values relate to public policies aimed at the conservation and sustainable use of these environments. The research was based on the analysis of the spatial dynamics of mangroves over time, using land use and land cover data, and on the application of the benefit transfer method to estimate the economic values associated with ecosystem services. In addition, a bibliometric analysis of the scientific production on environmental valuation, ecosystem services, and mangroves was conducted. The analysis indicated an increase in the area of mangrove forests, concomitant with a reduction in apicum areas, highlighting changes in the configuration of these coastal environments over recent decades. The bibliometric analysis revealed the evolution and thematic concentration of research on ecosystem services, indicating the growth of scientific interest in the topic and its relationship with global environmental agendas. The results of the environmental valuation indicated expressive values, especially for regulating services, reaching the order of billions of reais, highlighting the economic relevance of these ecosystems and enabling the analysis of the relationship between the estimated values for mangrove ecosystem services and the resources allocated in state planning instruments. Thus, the study sought to contribute to the advancement of scientific knowledge on the valuation of coastal ecosystems and to provide support for decision-making processes in the context of environmental management and the conservation of mangroves in Ceará.
