Atmospheric particle pollution causes acute and chronic health effects. Predicting the concentrations of PM 2.5 and PM 10 , therefore, is a prerequisite to avoid the consequences and mitigate the complications. This research utilized the machine learning (ML) models such as linear-support vector mac...

Natural ecosystems globally have been disrupted by anthropogenic activities, and the current biodiversity extinction rate exceeds the natural extinction rate by 1000-fold. Protected areas (PAs) help insulate samples of biodiversity from these human-induced threats; however, assessments of the factor...

Abstract Citizen science plays a crucial role in helping monitor biodiversity and inform conservation. With the widespread use of smartphones, many people share biodiversity information on social media, but this information is still not widely used in conservation. Focusing on Bangladesh, a tropical...

Citizen science programs are becoming increasingly popular among naturalists but remain heavily biased taxonomically and geographically. However, with the explosive popularity of social media and the near-ubiquitous availability of smartphones, many post wildlife photographs on social media. Here, w...

Protected areas have been established around the world to preserve samples of biodiversity from pressing threats. Yet the adequacy of protected area systems in many tropical nations is poorly understood, and assessments are usually focused on vertebrates. Here, we model the occurrence of 246 butterf...

Butterflies are important pollinators and indicators of environmental health. Habitat destruction and fragmentation caused by developmental activities and poor natural resource management are the main reasons for the drastic decline of butterfly populations throughout the world, and prompt the need ...

Abstract Cities currently harbour more than half of the world’s human population and continued urban expansion replaces natural landscapes and increases habitat fragmentation. The impacts of urbanisation on biodiversity have been extensively studied in some parts of the world, but there is limited i...

The tropics contain a vast majority of species, yet our understanding of tropical biodiversity is limited. Here we combine species locality data from scientific databases and social media to examine the coverage of species by existing protected areas in Bangladesh and identify priority areas for fut...

The expanding use of community science platforms has led to an exponential increase in biodiversity data in global repositories. Yet, understanding of species distributions remains patchy. Biodiversity data from social media can potentially reduce the global biodiversity knowledge gap. However, prac...

1. The expanding use of citizen science platforms has led to an exponential increase in biodiversity data in global repositories. Yet, our understanding of species distribution remains patchy for most of the world. Social media data has the potential to reduce the global biodiversity knowledge gap. ...

Citizen science programmes are becoming increasingly sophisticated and popular among those with an interest in natural history, but remain the domain of a relatively small portion of the public and heavily biased toward certain areas. Although systematic recording of biodiversity data has been pract...

Insects are the most speciose group of animals and play a central role in ecosystem processes and functioning, yet they are often overlooked in conservation studies. Many studies have reported a dramatic decline of insects globally, where climate change is considered a profound threat; however, how ...

Butterflies arernconsidered as one of the most studied groups of insects and are termed asrnbio-indicator. Hence the total number of butterflies of a certain region shouldrnbe well documented. In the field survey of Pablakhali Wildlife Sanctuary andrnMadhabkunda Eco Park, we found two butterflies wh...
