Since their introduction at the beginning of 19th century, Casuarina species have become important components Algerian landscape, yet numbers present in Algeria and identity, distribution, symbiotic status are still not well understood. A survey conducted on 2,304 trees 96 stands across indicates that they represented exclusively by five species: cristata Miq., C. cunninghamiana equisetifolia L...

The Pinnotheridae family is one of the most diverse and complex groups of brachyuran crabs, many of them symbionts of a wide variety of invertebrates. The present study describes the population dynamics of the pea crab Austinixa aidae (Righi, 1967), a symbiont associated with the burrows of the ghost shrimp Callichirus major (Say, 1818). Individuals (n = 588) were collected bimonthly from May, ...

In the recent past, nanobiotechnology field has grown up tremendously with more applications because synthesis process will be practically possible techniques. Since, plant-derived biosynthesis of silver nanoparticles is superior since its eco-friendly, cost-efficient, speedy in nature. Alginate-based biodegradable nanocomposite films were prepared Celosia cristata leaf extracts (CC-AgNPs) and ...
