Blood δ-ALAD, lead and cadmium concentrations in spur-thighed tortoises (Testudo graeca) from Southeastern Spain and Northern Africa

Mediterranean spur-thighed tortoise (Testudo graeca) is actually included in the IUCN as vulnerable species. Its main European population is located in southeastern Spain. Although a great deal of information has been acquired on the internal medicine and survey and even parasitological fauna on these animals, there are no references about contaminants levels in this species. The objectives of this study were to compare the levels of two metals (cadmium and lead) in the blood of spur-thighed tortoises from two different populations, one from Southeastern of Spain (n = 22) and the other from North of Africa (n = 39), kept in captivity at the Santa Faz Recuperation Centre (Alicante, Spain) and to investigate the relationship between their blood levels of lead and their blood delta-aminolevulinic acid dehydratase (delta-ALAD) activity. Blood lead and cadmium concentrations were higher in tortoises from African than in those from Spain. Moreover, a negative and significant correlation (P < 0.05) was found between delta-ALAD activity and blood lead levels, indicating the suitability of this enzyme as biomarker for lead in this species.

“…During this fourth session, the instructors also provided abstracts for three instructor-selected papers (Debruyn & Sayler, 2009; Hays & McBee, 2007; Yoo & Janz, 2003). These papers, along with the demonstration paper, were all related to a semester-long theme: Environmental and Health Impacts of the Tar Creek Superfund Site.…”

Active learning improves student performance in STEM courses. Exposure to active learning environments generally occurs through traditional laboratory courses and independent research, both of which require access to resources that are limited at many universities. A previously reported active learning-based undergraduate journal club improved student achievement in communicating science. Here, we expanded on this previous journal club to improve student performance in the process of science. We developed and implemented a series of workshops and seminars referred to as “CASL Club,” an undergraduate journal club targeted at improving student development in applying the scientific process. Students were surveyed before and after CASL club about their confidence in accessing, analyzing, and reporting scientific research. Post-CASL club, the students reported increases in confidence in their abilities to access and present scientific articles and write scientific abstracts. Additionally, the students reported improved confidence and performance in their courses. Compared to the previous journal club study, the majority of sampled journal club participants were not exposed to primary literature as part of their general coursework. Our results illustrate active-learning based undergraduate journal clubs as a way to expose students to primary literature and improve students’ ability to apply scientific process in an active-learning environment at resource-limited universities.

“…Zinc concentrations were elevated in waterfowl tissues, and cadmium con centrations were elevated in songbirds (Beyer et al, 2004). Elevated tissue lead and adverse health effects of lead expo sure have been recorded in a variety of other species in the Tri-State Mining District, including fish (Wildhaber et al, 2000), mussels and clams (Mytilidae and Corbiculidae; Angelo et al, 2007), red eared slider turtles (Trachemys scripta; Hays and McBee, 2007), white-tailed dcer (Odocoileus virginianus; Conder and Lanno, 1999), and midges (Chironomidae; Reynolds and Ferrington, 2002).…”

Lead and zinc poisoning have been recorded in a variety of bird species, including migrating waterfowl such as Canada Geese (Branta canadensis), at sites contaminated with mine waste from lead and zinc mines in the Tri-State Mining District, Kansas, Oklahoma, and Missouri, USA. The adverse health impacts from mine waste on these birds may, however, be more extensive than is apparent from incidental reports of clinical disease. To characterize health impacts from mine waste on Canada Geese that do not have observable signs of poisoning, four to eight apparently healthy birds per site were collected from four contaminated sites and an uncontaminated reference site, and examined for physical and physiologic evidence of metals poisoning. Tissue concentrations of silver, aluminum, arsenic, barium, cadmium, cobalt, chromium, copper, iron, magnesium, manganese, molybdenum, nickel, lead, selenium, thallium, vanadium, and zinc were determined by inductively coupled plasma mass spectroscopy. Adverse health effects due to lead were characterized by assessing blood δ-aminolevulinic acid dehydratase (ALAD) enzyme activity. Adverse effects associated with zinc poisoning were determined from histologic examination of pancreas tissues. Elevated tissue lead concentrations and inhibited blood ALAD enzyme activities were consistently found in birds at all contaminated sites. Histopathologic signs of zinc poisoning, including fibrosis and vacuolization, were associated with elevated pancreatic zinc concentrations at one of the study sites. Adverse health effects associated with other analyzed elements, or tissue concentrations indicating potentially toxic exposure levels to these elements, were not observed.
