Unmanned aerial vehicle (UAV) or drone image data are useful tools for creating machine learning-based mangrove categorization maps. Here, we present a protocol for creating a taxonomy map of mangrove species using machine learning and multispectral UAV images. We describe steps for gathering and analyzing UAV images and field data and categorizing mangroves. We then detail procedures for building a library of spectral reflectance and normalized difference vegetation index (NDVI) values and a tree classification map. For complete details on the use and execution of this protocol, please refer to Dung..

Mangrove ecosystems in Bedono Village, Demak Regency, Central Java, are seriously degraded due to aggressive coastal abrasion, extreme soil salinity (45‰-80‰), and failure of previous rehabilitation programmes. This study aims to assess the level of vulnerability of mangrove habitat and formulate an integrated rehabilitation strategy that includes ecological and institutional aspects. Data were collected through tidal analysis, measurement of sediment texture and soil salinity, identification of plankton and macrobenthos diversity, and analysis of mangrove species community structure.

However, mangroves, a specific species that have significantly declined in quantity and quality worldwide despite their numerous benefits, have not been the subject of attention. The novelty of this research is to deal with this species based on an advanced deep learning solution (a proposed ensemble U-Net model) and a high-resolution Planet satellite imagery (5 m x 5 m) in a case study of Ngoc Hien district, Ca Mau province, Vietnam.

Marine microorganisms have unique metabolic pathways due to their unique living environment, which enables them to produce many structurally special and highly active active substances. They are considered the most promising treasure trove of active substances for development. In this study, EPS was the extracellular polysaccharide (EPS) extracted from LAN4 which was identified as Limosilactobacillus fermentum isolated from seawater, sea mud, mangrove leaves, and soil.

(Rhizophoraceae), previously known from India (Andaman and Nicobar Islands), China to Indo-China, and the Pacific Island, is reported here as a new record from coastal areas with muddy-sandy, sandy or sandy-rocky substrates at Ko Lidi and Ko Bulon Le, within Mu Ko Phetra National Park, La-ngu District, and at Ao Talo Wao, Ko Tarutao, Tarutao National Park, Mueang Satun District, Satun Province, Peninsular Thailand. A detailed morphological description, illustrations and a distribution map of the species are provided, along with notes on distribution, habitat and ecology, phenology, a preliminary conservation assessment, etymology and specimens examined. In addition, is lectotypified, the Thai vernacular name "Kongkang phetra" is herein proposed for this species, and an updated identification key to the species of in Thailand is presented.

Marine habitats provide food and shelter, protect from erosion, filter pollutants, and support critical human activities, such as recreation, transport, and tourism. However, these ecosystems are increasingly vulnerable to plastic waste accumulation, particularly in island nations like the Philippines, where single-use plastics predominate in coastal regions. With a coastal population of over 70 million people, the welfare of the people of the Philippines is at risk from the negative impacts of plastic pollution; however, little is known about the impacts of plastic on biological processes.
