Present communication reports the diversity of intertidal Ophiuroidea (Phylum: Echinodermata) from zones Saurashtra coastline, Gujarat state. coastlines were extensively surveyed January 2019 to March 2022 for diversity. A total nine species belonging eight genera and six families noted coastline. Amongst these, Macrophiothrix variabilis, Ophiothrix savignyi Ophiomaza cacaotica are newly observ...

Estuarine ecosystems are becoming increasingly altered by the concentration of human populations near the coastline, however a robust indicator of this change is lacking. We developed an index of waterbird community integrity (IWCI) and tested its sensitivity to anthropogenic activities within 28 watersheds and associated subestuaries of Chesapeake Bay, USA. The IWCI was used as a tool to gain ...

BACKGROUND The International Shark Attack File mentions only four unprovoked shark attacks on the coast of West Africa during the period 1828-2004, an area where high concentrations of sharks and 17 species potentially dangerous to man have been observed. To investigate if the frequency of shark attacks could be really low and not just under-reported and whether there are potentially sharks tha...

Brook trout Salvelinus fontinalis have been used worldwide to stock fishless alpine lakes, negatively affecting native biota. Understanding its spatial ecology in invaded ecosystems can provide information to interpret and contrast its ecological impact. We opportunistically used capture points of brook trout gillnetted during an eradication campaign to assess the distribution patterns of four ...

This paper assesses sea-level rise related coastal flood impacts for Emilia-Romagna (Italy) using the Dynamic Interactive Vulnerability Assessment (DIVA) modeling framework and investigate the sensitivity of the model to four uncertainty dimensions, namely (1) elevation, (2) population, (3) vertical land movement, (4) scale and resolution of assessment. A one-driver-at-a-time sensitivity approa...

On wave-influenced river deltas, wave-driven sediment redistribution affects progradation, and therefore avulsions, while avulsions change where is delivered to the coastline, affecting coastline shape. Coastline shape, in turn, rates patterns. Here we use a numerical model investigate how asymmetry of wave climates delta avulsion behaviors, which are coupled with shape evolution. Increasing wa...
