12DNA metabarcoding the diet of Podarcis lizards endemic to the Balearic Islands显示文摘Dietary studies are essential to unravel the functioning of ecosystems and ultimately to understand biodiversity.This task,which at first may seem simple,becomes especially complex in those cases of omnivorous species with highly variable diets.In this regard,the emergence of next-generation DNA sequencing methodologies represents a powerful tool to address the problem.Here we implement a high-throughput metabarcoding strategy based on the analysis of four molecular markers aimed at sequencing both mitochondrial(animal prey)and chloroplast(diet plants)genome fragments from fecal samples of two lizard species endemic to the Balearic Archipelago(Podarcis lilfordi and P.pityusensis)obtained through non-invasive methods.The results allowed for the characterization of their diets with a high degree of taxonomic detail and have contributed a large number of new trophic records.The reported diets are based mainly on the consumption of arthropods,mollusks and plants from a diversity of taxonomic orders,as well as carrion and marine subsidies.Our analyses also reveal inter-and intra-specific differences both in terms of seasonality and geographical distribution of the sampled lizard populations.These molecular findings provide new insights into the trophic interactions of these threatened endemic lizards in their unique and isolated ecosystems.Iris Alemany Ana Pérez-Cembranos Valentín Pérez-Mellado JoséAurelio Castro Antònia Picornell Cori Ramon JoséA Jurado-Rivera 2023Current Zoology2023,69,5:0
13Coping with drought?Effects of extended drought conditions on soil invertebrate prey and diet selection by a fossorial amphisbaenian reptile显示文摘Arid climates are characterized by a summer drought period to which animals seem adapted.However,in some years,the drought can extend for unusually longer periods.Examining the effects of these current extreme weather events on biodiversity can help to understand the effects of climate change,as models predict an increase in drought severity.Here,we examined the effects of“unusual”extended drought on soil invertebrate prey availability and on diet composition(based on fecal contents)and diet selection of a fossorial amphisbaenian,the checkerboard worm lizard Trogonophis wiegmanni.Weather data show interannual variations in summer drought duration.The abundance and diversity of soil invertebrates in spring were high,and similar to those found in a“normal”early autumn,after some rain had ended with the summer drought.In contrast,in years with“unusual”extended drought,abundance,and diversity of soil invertebrates in early autumn were very low.Also,there were seasonal changes in amphisbaenians’diet;in autumn with drought,prey diversity,and niche breadth decreased with respect to spring and autumns after some rain had fallen.Amphisbaenians did not eat prey at random in any season,but made some changes in prey selection that may result from drought-related restrictions in prey availability.Finally,in spite that amphisbaenians showed some feeding flexibility,their body condition was lower in autumn than in spring,and much lower in autumn with drought.If extended drought became the norm in the future,amphisbaenians might suffer important negative effects for their health state.José Martín Jesús Ortega Roberto García-Roa Gonzalo Rodríguez-Ruiz Ana Pérez-Cembranos Valentín Pérez-Mellado 2023Current Zoology2023,69,4:0
14Anabolic steroid-induced cardiomyopathy underlying acute liver failure in a young bodybuilder显示文摘Heart failure may lead to subclinical circulatory disturbances and remain an unrecognized cause of ischemic liver injury. We present the case of a previously healthy 40-year-old bodybuilder, referred to our Intensive-Care Unit of Hepatology for treatment of severe acute liver failure, with the suspicion of toxic hepatitis associated with anabolic steroid abuse. Despite the absence of symptoms and signs of congestive heart failure at admission, an anabolic steroid-induced dilated cardiomyopathy with a large thrombus in both ventricles was found to be the underlying cause of the liver injury. Treatment for the initially unrecognized heart failure rapidly restored liver function to normal. To our knowledge, this is the f irst reported case of severe acute liver failure due to an unrecognized anabolic steroid-induced cardiomyopathy. Awareness of this unique presentation will allow for prompt treatment of this potentially fatal cause of liver failure.Miguel Bispo Ana Valente Rosário Maldonado Rui Palma Helena Glória Joo Nóbrega Paula Alexandrino 2009World Journal of Gastroenterology2009,15,23:0
