Sea turtle epibionts can provide insights into the hosts' habitat use. However, at present, there is a lack of information on sea turtle epibiont communities in many locations worldwide. Here, we describe the epibiont communities of 46 hawksbill turtles (Eretmochelys imbricata) in the Persian Gulf. Specifically, we sampled 28 turtles from the Dayye...

جنس و عمق قرارگیری بستر­­های سخت در پراکنش مکانی گونه‌های بیوفولینگ نقش کلیدی بازی می‌کنند. اویستر Saccostrea cucullata ازجمله گونه‌های بیوفولینگ سواحل خلیج فارس می‌باشد. به ‌منظور تعیین تأثیر جنس بستر بر پراکنش این گونه، تراکم اویسترها روی سه نوع بستر سخت شامل صخره‌های طبیعی، بلوک‌های سیمانی و سطوح فلزی در دو فصل تابستان و زمستان 1395 در مناطق بین...

Fouling species display characteristics that make them suitable options for bioremediation of aquaculture effluents. We studied the potential use of two fouling species (Amphibalanus amphitrite and Saccostrea cucullata) in remediation of shrimp (Litopenaeus vannamei) farm wastewaters. Their abilities, individually and in combination, in reducing ni...

Illegal hunting of ungulates can reduce the prey base of carnivores, which can increase human–carnivore conflict ( HCC ) through livestock depredation. However, the relationship between ungulate poaching, wild prey abundance and livestock depredation has rarely been empirically studied. We surveyed 18 sites across the Hyrcanian forest in northern I...

Poaching is cryptically but rapidly driving many species towards extinction. Knowledge of population trends of exploited species and incentives for poaching is necessary to inform appropriate conservation measures. We estimated the abundance of four ungulate species in Golestan National Park, Iran, the country's oldest protected area, where poachin...

The potential application of settling ponds and two fouling filter-feeder species Amphibalanus amphitrite and Saccostrea cucullata to bioremediate semi-intensive shrimp farm effluent through 6 hours residence time was investigated. Settling pond reduced total nitrogen, total phosphorus and chlorophyll a to 80.5%, 77.8% and 94.3% of the initial conc...

Introduction: Invasive fishes are a major threat to biodiversity of aquatic ecosystems. Tilapia species are invasive due to their reproductive, diet and behavioural characteristics and high resistance to environmental conditions, pollution and diseases. So far, two exotic species Coptodon zillii and Oreochromis aureus, as well as a native species I...

Lagoons can be regarded as life-giving systems that are irreplaceable. These ecosystems have been always being damaged by human. This study was carried out in during Aug- 2010 between Solokli and Shormast lagoons in the north of Iran in order to assessing degree of water pollution via contrasting biodiversity of lagoons. in this study were identifi...

The maral red deer Cervus elaphus maral, once widespread throughout the whole Hyrcanian and Caucasus forests in southwest Asia, has undergone a dramatic decline due to heavy poaching and habitat transformation. Maral is now extinct in the wild in western and northwestern Iran, but still persists in the Caspian montane forests of northern Iran, also...

Overexploitation of wildlife for meat is a widespread phenomenon, which drives populations of many species toward extinction and may in turn affect large carnivores. Therefore, human hunters may compete with large carnivores over food resources and threaten their survival. In this study, we assessed the trophic competition of endangered Persian leo...

Based on the gut content analysis of 278 specimens of brown trout, Salmo trutta, in the Lar Reservoir and its basin, including streams of Delichay, Ab Sefid, Elarm, Lar and Siah Plas, the summer food habits were found to be general and depended on the abundance of preys. Considering the “index of relative importance” in all stations, the most consu...

The elusive Caspian red deer Cervus elaphus maral lives at low densities in rugged forest habitats of the Caucasus and the south Caspian region, and its declining population requires urgent attention. We here address the precision and reliability of dung counts (fecal standing crop approach FSC) and camera trapping (random encounter model REM) for...

Ranger stations are essential to combat poaching in protected areas and the distance from ranger stations is sometimes used as a proxy for poaching levels and law enforcement intensity. However, the influence of the spatial distribution of ranger stations on wildlife abundance and population structure has rarely been investigated. We evaluated the...

The Persian Gulf harbours a group of islands off the Iranian coast, with known and distinct times of isolation, that are a result of sequential separation from the mainland because of rising sea levels subsequent to the last glaciation. In the present study, we examine the variation in the morphology of Brandt's hedgehogs Paraechinus hypomelas (Mam...

Livestock is represented in big cat diets throughout the world. Husbandry approaches aim to reduce depredation, which may influence patterns of prey choice, but whether felids have a preference for livestock or not often remains unclear as most studies ignore livestock availability. We assessed prey choice of the endangered Persian leopard (Panther...

The blue tilapia, Oreochromis aureus (Steindachner, 1864) is recorded for the first time from the Arvand and Karun River drainages in Khuzestan province, Iran.

For some time, the vittata phenotype of Wheatear has been considered as a subspecies of Pied Wheatear O. pleschanka (Lepechin, 1770). Systematic location of Oenanthe pleschanka vittata (Hemprich et Ehrenberg, 1833) remains unclear for some reasons. This rare phenotype has frequently recorded by some local birders and travelers in eastern and north...
