Trachemys scripta (Reptilia, Emydidae) is among the most widespread invasive reptiles in world. In general, it assumed that this species has negative effects on native aquatic turtles based experiments conducted under controlled conditions. Here, we analysed a 7?year time series (2013?2019) of data from captures three (two natives and one alien) natural populations northeastern Iberian Peninsul...
Abstract Ecological niche modelling provides a useful tool to measure properties such as breadth, overlap and conservatism among genetic lineages, with relevant implications for conservation. The Mediterranean pond turtle Mauremys leprosa occurs on both sides of the Strait Gibraltar over most Iberia Maghreb Region north-western Africa, where it shows complex structure result Pleistocene climati...
The effect of broad-leaved forest trees (Alnus glotinusa, Ulmus glabra, Popolus caspica and Parrotia persica) and their canopy position on soil C and N storage and mineraization in the plain forest areas of Noor was investigated. Soil samples were taken from two positions (near and away from the main stem) with the microplots of 30×30×15 cm. Litter (C and N), soil physical (bulk density, textur...
زمینۀ مطالعه: استفاده از محرک‌‌‌‌های ایمنی طبیعی یکی از مؤثرترین روش‌‌‌‌ها برای تقویت ایمنی و پیشگیری از بیماری در ماهیان است. هدف: با توجه به فراوانی جلبک قرمز (Laurencia caspica) در دریای خزر، هدف از انجام تحقیق حاضر، بررسی اثر این جلبک بر عملکرد رشد و شاخص‌‌‌‌های خونشناسی ماهی قزل‌‌‌‌آلای رنگینکمان بود. روش‌کار: مطالعه حاضر روی 750 قطعه بچه‌ماهی قزل‌‌‌‌آلای رنگینکمان که به طور تصادف...
Cartilaginous deposits are regularly present in the heart of several reptilian, avian, and mammalian species. The formation of these extraskeletal cartilages has been studied in birds and mammals, but not in reptiles. The aim here was to elucidate this question in the Spanish terrapin. Hearts from 23 embryos belonging to Yntema (1968) developmental stages 17 to 26 and eight terrapins age 3 mont...
