This article contributes to the diversity and stand structure of mangroves in Kerala, India, using multivariate methods. Floristic comprised 18 species true mangroves, which Sonneratia alba, Avicennia Ceriops tagal were found be rare, whereas Bruguiera parviflora was extinct state. Structural analyses revealed importance officinalis domination Acanthus ilicifolius. The mean stem density ranged from 10 13846 no/ha, basal area 0.02 20.19 m2/ha. Multivariate analysis could classified into five...

Abstract We estimated the tree structural variables (density, frequency and basal area) of true mangroves soil like particle size distribution, carbon, available nitrogen phosphorus, sulphur, nutrient cations (K, Na, Ca, Mg) Cochin examined relationship between vegetation environment. The study sites were classified as seaward fringe, riverine interior. Of thirteen mangrove species present, Avicennia officinalis , Sonneratia caseolaris Excoecaria agallocha showed higher Importance Value...

A new species of mangrove sesarmid crab the genus Pseudosesarma Serène & Soh, 1970, is described from Cochin, southwest India. The superficially resembles P. edwardsii (De Man, 1887), known Myanmar and many parts India; proportions carapace male pleon also ally it with crassimanum 1887) Myanmar, Sri Lanka Southeast Asia. glabrum n. sp., however, easily separated primarily by almost glabrous dorsal surface distinctive form its first gonopod.

Abstract The diversity, abundance and community structure of mesozooplankton from the hydrographically differing mangrove habitats in Cochin, Kerala (India), were investigated. Eleven zooplankton groups identified, with calanoid copepods (62%) comprising predominant population, followed by crustacean nauplii (22%) mysids (12%). Nitrogen limiting (N: P ratio 5.13 ± 7.03) a mixo‐mesohaline salinity (8.96 3 psu) relatively low temperatures (30.28 0.9 °C) was characteristic feature study zones....

Area-based protection is an important tool for safeguarding key habitat. Reserves that focus on mitigation of specific threats are particularly effective and more likely to support a measurable outcome. In the marine environment, reserves limit vessel presence have potential reduce disturbance mammals. However, assessing efficacy has been ongoing challenge. Physical acoustic from vessels recognized as primary threat recovery northern resident killer whale (NRKW) population in Canadian...

<title>Abstract</title> Nanobiotechnology is a rapidly growing field with numerous applications in the medical field. The discipline combines biological research various fields of nanotechnology. Nanodevices, nanoparticles, and nanoscale phenomena within nanotechnology are enhanced through nanobiology. Typically, nanoparticles synthesized using either top-down or bottom-up approach. However, these chemical methods can be dangerous as they involve handling toxic chemicals producing...
