Identifying and tracking individuals across time are a prerequisite to uncover key traits of their ecology behavior. However, obtaining fine-grain individual data at multiple locations, especially in aquatic environments, is challenging due trade-offs between constraints detection probabilities. Aquatic telemetry passive integrated transponder (PIT)-tagged organisms has been proposed cope with ...

Most cnidarian-microalgae symbioses exhibit some degree of specificity in host-symbiont pairing. Among taxa with aposymbiotic larvae, specificity must be established each generation. Newly settled polyps of the gorgonians Plexaura kuna and Pseudoplexaura porosa rapidly acquired zooxanthellae, in both laboratory and field settings. Initial zooxanthella acquisition by polyps was non-selective and...

Epidemiological and experimental studies indicate that environmental and dietary factors are probably important determinants of colorectal cancer (CRC). Among dietary factors alcohol intake has been shown to be associated with an increased risk of CRC (1). A large number of epidemiologic studies have examined the possible association of beer and ethanol ingestion on CRC risk. As a result, some ...

The aim. aim of the work was to study indicators spermatogenesis in lake frog, Pelophylax ridibundus (Pallas, 1771), zone influence emissions from Burshtyn Thermal Power Plant (TPP).
 Materials and methods. Urinal sperm testes samples were taken male frogs under conditions anthropogenic pollution (Burshtyn industrial area). Such parameters as concentration ejaculate, number live spermatozo...
