“…While sites with low canopy closeness can be widely used by edge foragers, only those sites harbouring increased NDVI may represent suitable habitat for manoeuvrable forest dependent species that are further adapted to echolocate in more cluttered environments (Froidevaux et al, 2016;Suarez-Rubio et al, 2018). By allowing forest foragers to persist, habitat quality contributes to maintain bat diversity, as also observed for other biological groups, e.g., large-sized mammals and reptiles (Oliveira et al, 2020;Silva et al, 2022). This is further supported by the increase in forest bat activity we observed in denser forests.…”

Despite mounting evidence on the ecological impacts of damming for biodiversity, little is known regarding its consequences in the hyper-diverse Southeast Asian tropical forests. Here we assess the effects of habitat loss and fragmentation on the diversity and activity of insectivorous bats within the hydroelectric Kenyir Lake in peninsular Malaysia. We surveyed bat assemblages on 26 islands and two mainland continuous forest sites using passive acoustic monitoring. Echolocation calls were classified into sonotypes, each corresponding to either one or multiple species, and grouped into foraging guilds. We then examined bat overall assemblage (sonotype richness, activity, and composition), guild- and sonotype-specific activity. From 9360 hours of recordings, we identified 16 bat sonotypes, including 10 forest (2854 bat passes), three edge (13 703) and three open-space foragers (3651). Sonotype richness increased towards denser forest structures (higher Normalized Difference Vegetation Index - NDVI), while species composition varied across the gradient of forest area. Forest foragers were positively affected by NDVI and negatively affected by distance to the closest neighbour, whereas edge foragers' activity increased in smaller islands. Of the six sonotypes analysed, the activity of one forest sonotype increased with forest area, while that of one edge sonotype decreased. Ensuring habitat quality within insular forest remnants, in addition to their functional connectivity, maximises bat diversity, including the persistence of forest foraging species. Future hydropower development should therefore avoid the creation of a myriad of small, isolated, and habitat-degraded islands further characterised by altered levels of bat diversity and guild-level activity.

“…If it is set to year, then we get and respectively, then the following functions are used for the coupling degree analysis: (5) In the above Equation, the coupling degree value , is set to 0.5, and the coupling degree value is proportional to the coupling degree. Because the development levels have their different degrees of difference, and the calculated weight values of both subsystems are relatively low, this paper thus introduces the model, which can better reply to the coordination degree of the interactive coupling, and the function is shown as follows: (6) The coupling degree is combined with the comprehensive development level of urbanization development and ecological environment system to calculate the coupling coordination degree of the system , i.e.…”

To maintain the ecological environment and protect the sustainable development of natural resources, this paper proposes a study on ecological construction and environmental management in large and medium-sized cities in the context of city- industry integration. The spatial layout, environmental capacity, and environmental quality are clearly deficient in the situation related to the integration of industrial and urban areas. Analyze the problems of ecological construction and environmental management in governance, construct an index system for the coordinated development of ecological and environmental systems, and measure the coupled and synergistic dispatch of cities and ecological environments. Eliminate dimensions, variable changes and values so that benefit and cost metrics are consistent. The information entropy of each index is calculated by using the original information of the objective environment, and the weights are determined after standardizing them to obtain a comprehensive index of the development level of urbanization and the ecological environment system. The coupling coordination model is used to measure two or more system linkage indicators, reflecting the degree of coordination of the interactive coupling of economic growth and the ecological environment. The analysis of the results shows that the ecological development of urbanization is steadily increasing, and the level of ecological development has grown to 0.7291 and the level of urbanization development has increased to 0.8950 over time, with a good degree of coordination of coupling.

“…No entanto, essas espécies são relativamente comuns em regiões próximas do Pantanal (Rodrigues et al 2002). Embora estudos mostrem que alguns mamíferos como os cervídeos registrados, podem utilizar paisagens formadas por fragmentos florestais e áreas de matrizes agrícolas (Giozza et al 2017), sabe-se que a sobrevivência dessas espécies a longo prazo depende da quantidade e qualidade de habitat disponível, tipo de matriz e tamanho e conectividade dos fragmentos (Oliveira & Hannibal 2017, Rocha et al 2018, Oliveira et al 2019. Portanto, considerando a importância das duas espécies ameaçadas de cervídeos, sugerimos que as áreas em que as mesmas foram registradas no entorno das UC, sejam avaliadas em relação a incorporação no território do MNMSBJ, aumentando assim a sua proteção.…”

“…Associado a isso, apesar de o estado de MS abrigar uma diversidade elevada de mamíferos, com 146 espécies, sendo 47 de médio e grande porte (Tomás et al 2017), aproximadamente 38 % dessas espécies estão ameaçadas de extinção (Torrecilha et al 2018). Nesse sentido, a proteção de remanescentes de vegetação contínua e a estrutura da paisagem representam um fator importante que influencia a composição das espécies de mamíferos , Oliveira et al 2019. Contudo, menos de 1 % do território de MS é composto por unidades de conservação de proteção integral, como Parques e Monumentos Naturais (Torrecilha et al 2017).…”

A perda e fragmentação de habitats constitui uma das maiores ameaças à fauna, principalmente aos mamíferos terrestres de médio e grande porte. Considerando as ameaças contínuas que os remanescentes de Cerrado sofrem, é essencial realizar inventários de mamíferos em áreas ainda pouco pesquisadas. Para avaliar a riqueza de espécies e a frequência relativa de mamíferos de médio e grande porte foram aplicados os métodos de visualização direta e registro por armadilhas fotográficas. O estudo foi realizado entre fevereiro e agosto de 2020, no Monumento Natural Municipal Serra do Bom Jardim, em Alcinópolis, Mato Grosso do Sul – MS. A partir de um esforço amostral 840 armadilhas-noite e 224 horas de buscas direta, foram registradas 27 espécies de mamíferos nativos, equivalente a 57.4 % das espécies desse grupo presentes no MS. A curva de acumulação de espécies associada com a riqueza estimada (Jackknife-1) indica que a continuidade da amostragem deve adicionar novas espécies. Duas espécies foram responsáveis por mais de 60 % dos registros fotográficos (Tapirus terrestres e Cerdocyon thous). Nosso inventário adicionou três novas ocorrências ao plano de manejo da UC (Didelphis albiventris, Leopardus tigrinus, e Coendou prehensilis). O registro de ocorrência de L. tigrinus por armadilha fotográfica é o primeiro para o estado de MS. Esse é o único carnívoro com ocorrência no Brasil que está ameaçado globalmente. Obtivemos registros de mais de 50 % das espécies ameaçadas de extinção presentes no MS, sem considerar L. tigrinus. Duas delas por exemplo, Ozotoceros bezoarticus e Priodontes maximus, estão entre as espécies mais raras em território sul mato-grossense. Nossos registros contribuem para a execução de medidas de conservação dos mamíferos na UC estudada, que desempenha um papel fundamental para a proteção do corredor Cerrado-Pantanal. MEDIUM AND LARGE SIZED MAMMALS IN PROTECTED AREA AT CERRADO, MATO GROSSO DO SUL, BRAZIL: Habitat loss is one of the greatest threats to fauna, especially for medium to large-sized terrestrial mammals. Considering the continuous threats on Cerrado remnants, it is essential to carry out mammal inventories in areas with low information available. In order to evaluate the species richness and the relative frequency of medium and large mammals, we investigated the area with direct observations and using camera traps. The study was conducted from February to August 2020, in the Serra do Bom Jardim Municipal Natural Monument, in Alcinópolis, Mato Grosso do Sul State (MS). From a sampling effort of 840 trap-nights and 224 hours of direct observations, a total of 27 species of native mammals were registered, representing 57.4 % of medium and large species that occur MS. Species accumulation curve associated with estimated richness (Jackknife-1) indicates that continued sampling would add new species. Two species were responsible for more than 60 % of the photographic records (Tapirus terrestre and Cerdocyon thous). Our survey added three new occurrences to the protected area management plan (Didelphis albiventris, Leopardus tigrinus, and Coendou prehensilis). The occurrence of L. tigrinus is the first record for the state of MS. This is the only globally threatened carnivore in Brazil. We recorded more than 50 % of the endangered species present in MS, besides L. tigrinus. Two of endangered species, Ozotoceros bezoarticus and Priodontes maximus, are among the rarest species in MS. Our study contributes to conservation measures proposed by municipal protected area, which plays a fundamental role for wildlife conservation in the Cerrado-Pantanal corridor.
