زمینه و هدف: شناخت عوامل محیطی موثر بر حضور گونه­ها یکی از مهم­ترین موضوعات در علم بوم­شناسی است و آگاهی از نحوه تاثیر پذیری گونه­ها از متغیرهای محیطی می تواند کمک موثری برای حفاظت از گونه­ها مخصوصا انواع در خطر انقراض به حساب آید. بدین منظور در پژوهش حاضر به شناسایی متغیرهای زیستگاهی تاثیرگذار بر حضور سوسماران منطقه حفاظت شده الوند پرداخته شد. روش بررسی: منطقه حفاظت شده الوند با مساحت 8618 هکت...

To date, no published study has assessed the full physiological scope of a marine invertebrate species with respect to both temperature and hydrostatic pressure. In this study, adult specimens of the shallow-water shrimp species Palaemonetes varians were subjected to a temperature/pressure regime from 5 to 30°C and from 0.1 to 30 MPa. The rate of oxygen consumption and behaviour in response to ...

Immature sheepshead minnows (Cyprinodon variegatus), inland silversides (Menidia beryllina), mosquitofish (Gambusia holbrooki), and grass shrimp (Palaemonetes pugio) were exposed to the mosquito adulticide, Permanone 31-66, in a series of static toxicity tests conducted in the laboratory. At 24 h, in order of decreasing susceptibility, LC50 values were 0.843, 4.07, 5.46, and 6.04 ppb for grass ...

Presently, the use of protective food additives such as benzoic acid and sodium nitrate is quite common. However, it was found that these additives, which initially appeared to be harmless, led to the emergence of a number of health problems. Cancer and diseases and deaths with no apparent causes are among the leading concerns. Therefore, the studies which can reveal the genotoxic potential of ...

Ratiometric Nanothermometers Organic nanoparticles based on persistent TTM radicals containing excimers and isolated molecules exhibit all characteristics of ratiometric nanothermometers showing excellent temperature sensitivity, reversibility, high colloidal stability. In-vivo experiments made with Caenorhabditis elegans (C. elegans) indicate that they can monitor changes at the (nano)-micron ...
