A free-ranging subadult, male green turtle () presented with radiographic evidence of pneumonia and died acutely. On necropsy, the trachea and bronchi were plugged by diphtheritic membranes, comprised of fibrin, necrotic debris, and colonies of bacilli, identified as . , typically considered an opportunistic plant pathogen, has rarely been described as causing disease in animals. This is the first report of causing severe necrotizing tracheitis and bronchopneumonia in a reptile.

Differences in trophic level may result in differences in chemical exposure between species of sea turtles, as pollutants may bioaccumulate differentially in diet items. It is, therefore, crucial to understand species-specific differences in exposure and effect to accurately assess chemical risk to individual species. This study used blood collected from green and loggerhead turtles foraging in Moreton Bay, Queensland, Australia, to assess differences in chemical exposure and effect of two species foraging in the same area at different trophic levels.

Background: People with diabetes are at increased risk of hospitalisation, morbidity, and mortality following SARS-CoV-2 infection. Long-term outcomes for people with diabetes previously hospitalised with COVID-19 are, however, unknown. This study aimed to determine the longer-term physical and mental health effects of COVID-19 in people with and without diabetes.

The green sea turtle () is the only sea turtle species that breeds in China, and the largest remaining nesting grounds for green sea turtles in Chinese waters is found on the Qilianyu atoll of the Xisha Islands. Nesting site selection is particularly important for egg survival, and understanding the microhabitat characteristics of green sea turtle nesting sites is crucial for delineating priority conservation areas for nesting grounds. In this study, we aimed to examine the role of several microhabitat ecological factors in the selection of nesting sites and the success of nesting.

As temperatures rise due to increasingly severe global warming, the effect of high temperatures on wildlife, including green sea turtles, is one of the issues that must be addressed to ensure the conservation of biodiversity. In the current study, we found that green sea turtle cell death due to apoptosis occurred at 37 °C, which suppressed cell proliferation. We also found that high temperature-induced heat stress led to the accumulation of DNA damage in green sea turtle cells.

The rising diversity and concentration of contaminants have surpassed ecological thresholds, threatening marine ecosystems. The effects of pollutants on marine animals, particularly sea turtles, are receiving increased attention due to their role as indicators of human impacts. This study examined the health implications of contaminant exposure in three green turtle (Chelonia mydas) foraging sites in the southern Great Barrier Reef, Australia.
