ABSTRACT The Pontal Island, located in the Parque Natural Municipal de Niterói, stands out as a vital remnant of the Atlantic Forest in Rio de Janeiro. With ecosystems including forest, rocky outcrops, restinga, and man...

Forest fires have exhibited an escalating trend in both frequency and intensity globally, with major and catastrophic events causing significant damage to forest resources, human lives, and property. Timely and accurate ...

ABSTRACT This study was conducted in a fragment of montane seasonal semi-deciduous forest (Minas Gerais State) with a history of anthropogenic disturbance. Our goals were to characterise the composition, structure and fl...

Urban forests significantly benefit cities and people´s wellbeing. However, under suboptimal growth conditions, they can pose risks. The tree risk and tree hazard assessments in public spaces bring together several prot...

Forest fragmentation poses a critical threat to ecosystem service functionality, particularly in rapidly urbanizing regions. This study investigates the spatio-temporal dynamics of forest fragmentation and its impacts on...

Abstract Research on the dynamics and driving mechanisms of submerged macrophytes communities during the natural restoration period of lakes with different trophic level remains relatively scarce. This study aims to inve...

Abstract Green urban areas act as refuges for the nests of stingless bees, during reproduction, in response to niche constraints. This study investigated the characteristics of natural colonization by stingless bees in t...

The Garbhanga Reserve Forest, located on the south-western side of Guwahati City, covers an area of about 117 km2 and borders the foothills of Meghalaya (26°05´36˝N and 91°44´57˝E). Despite the constant threat of e...

Abstract Bryophytes disperse efficiently via wind-borne spores, yet long-distance transport alone does not guarantee successful establishment at the deposition site. Species-rich hotspots are expected to arise where a su...

Urban sprawl, the uncoordinated and spatially dispersed expansion of urban areas into surrounding rural lands, poses significant challenges to sustainable development, resulting in the loss of agricultural and forest lan...

Some urbanization impacts on biodiversity are often underestimated such as noise pollution generated by anthropogenic activities. Birds inhabiting urban and peri-urban areas suffer anthropogenic noise that impact their c...

Background: Extreme heat poses growing public health challenges, particularly in rapidly urbanizing regions. Assessing heat vulnerability at the county level is crucial for guiding adaptation strategies. Methods: A count...

Many developing countries have experienced rapid industrial and urban expansion over the last two decades, raising concerns about ecological degradation. However, quantitative assessments linking urbanization and ecologi...

Urban growth has reshaped land use patterns globally, demanding robust and scalable methodologies to monitor its long-term dynamics. This study proposes a GeoAI-based framework that integrates Random Forest (RF) classifi...

Acoustic indices provide a statistical method to quantify and assess relationships between soundscapes and avian diversity; however, more testing is necessary before acoustic indices are accepted as suitable proxies for ...

Abstract The increase in vehicle ownership and urban population puts a strain on roads and increases traffic congestion within developed and developing nations. Congestion affects an individual’s time and increases an ...

RESUMO Rubiaceae no Brasil ocorre principalmente no Bioma Mata Atlântica que na região sul é representado por dois tipos principais de fitofisionomias: Floresta Estacional Semidecidual e Floresta Ombrófita Mista. Amb...

Abstract Representatives of the families Didelphidae, Echimyidae, Cricetidae, and Muridae have been identified as significant reservoirs or amplifiers of zoonotic agents. This study aimed to investigate the molecular occ...

ABSTRACT Solar radiation is one of the aspects which most influence species composition, so light is a limiting factor to tree growth in forests. This study aimed to evaluate the leaf morphological variations between ind...

As abelhas africanas (Apis mellifera scutellata) foram trazidas para o Brasil na década de 1950 e, por acidente, cruzaram-se com outras subespécies de abelhas melíferas européias introduzidas no século XIX. Isso pro...

Abstract Background The research shows the impact of land use forms and population density on the spatial variation of COVID-19 cases and deaths. Selected elements of land use that influence the number of COVID-19 cases ...

Abstract Air pollution is a major environmental and public health challenge in Greater Cairo due to rapid urbanization, intense traffic activity, and recurrent regional dust intrusions. This study presents a data driven ...
