a simple, highly sensitive, accurate and selective method for determination of trace amounts of cu2+ in water samples was reported. in this paper, isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (iide) in order to prepare an effective sorbent for the preconcentration and determination of cu. the sorption capacity of isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (ii...

Abstract Loggerhead sea turtle ( C. caretta ) is the official European bioindicator of marine litter in Mediterranean Sea. In 2019, 8 turtles, out 28 specimens loggerhead on Adriatic coast Molise, were subjected to necropsy. The intestinal contents collected and microplastics until 0.45 ?m extracted. Qualitative quantitative assessments performed by stereomicroscope observation spectroscopic an...

Ingestion of artificial debris is considered as a significant stress for wildlife including sea turtles. To investigate how turtles react to artificial debris under natural conditions, we deployed animal-borne video cameras on loggerhead and green turtles in addition to feces and gut contents analyses from 2007 to 2015. Frequency of occurrences of artificial debris in feces and gut contents col...

Interactions between large marine predators and their prey are difficult to observe and little is known about the risk of predation faced by sea turtles. The frequency of predator-inflicted injuries, however, has afforded insights into the predation risk faced by many taxa. We measured the frequency of shark-inflicted injuries on green (Chelonia mydas) and loggerhead (Caretta caretta) sea turtl...

It is important to understand the population structure and space use of sea turtles because of their potential effects on the dynamics of nearshore ecosystems. Much of our current understanding is skewed because the ecology of sea turtles on their foraging grounds is known best from areas where there are, or have been, major human impacts. We studied green Chelonia mydas and loggerhead Caretta ...

OBJECTIVE To determine reference intervals for concentrations of plasma total protein (TP) and electrophoretogram fractions (ELFs) for healthy, wild loggerhead sea turtles (Caretta caretta) and green turtles (Chelonia mydas) and to assess relationships between TP and ELF concentrations and health status, body size, body mass, and water temperature. DESIGN Evaluation study. ANIMALS 437 healt...

Biochemical and hematologic reference intervals have been reported for loggerhead sea turtles (Caretta caretta, Linnaeus 1758), but low sample numbers and simple statistical analyses have constrained their diagnostic usefulness. During June 2007-May 2008, 101 loggerhead sea turtles in Moreton Bay, Queensland, Australia, were captured by hand from boats; clinically assessed to determine health s...

Recent studies showed that regional abundance of loggerhead and leatherback turtles could oscillate interannually according to oceanographic and climatic conditions. The Western Mediterranean is an important fishing area for the Spanish drifting longline fleet, which mainly targets swordfish, bluefin tuna, and albacore. Due to the spatial overlapping in fishing activity and turtle distribution,...

Loggerhead turtles that nest in the Mediterranean sea are geographically and genetically distinct from the North Atlantic (NA) other populations of loggerhead turtles. The individuals belonging to the Mediterranean population, even though belonging to the same species, are consistently (at birth, puberty, and ultimate size) smaller than their conspecifics of the North Atlantic population. Becau...

Sea turtles are widely distributed in temperate and tropical seas, and their carapace is often colonized by species of macroalgae. There have been several studies on the epibionts of loggerhead turtles, Caretta caretta Linnaeus, from different parts of the world (KITSOS, et al., 2005; PFALLER et al., 2006, 2008). The carapaces of loggerhead turtles represent an important substratum for a variet...
