Terrestrial vertebrates of Dobrogea - Romania and Bulgaria

The authors report the state of the terrestrial vertebrates of Romanian and Bulgarian Dobrogea. Five amphibian species, eight of reptiles, 159 of birds and 39 mammals species were inventoried. Some of them are characteristic to the steppe areas, in which Dobrogea is included, and others (as amphibians) have a limited distribution, around water flows, pools and lakes. Some of the observed or collected species have populations which can be compared in the two parts of Dobrogea, while the others (e.g. Crocidura suaveolens, Mesocricetus newtoni, Microtus arvalis) have populations more numerous in the Bulgarian Dobrogea, this thing indicating that there are several undamaged habitats and a low anthropic pressure than in the Romanian one.

Abstract

The present study aims to identify and analyse the cardiometabolic risk factors associated with the metabolic syndrome in overweight children and adolescents. The study group included 163 overweight children and adolescents, average age: 13.02 ± 3.42 years. The following evaluations were performed: anthropometrical measurements, blood pressure measurements, biochemical tests investigating the lipid and carbohydrate metabolism. Metabolic syndrome was identified in 48 subjects (29.4%). The risk to develop MS was found to be higher in males and within the 13-18 age group. The most common cardiometabolic risk factors were abdominal obesity (75.5%) and high blood pressure (41.1%), followed by low HDL-cholesterol (35%), increased fasting blood glucose (23.3%) and hypertriglyceridemia (17.8%.). The variables under analysis exhibited significant correlations with the number of metabolic syndrome diagnosis criteria. The metabolic syndrome prevalence in the paediatric population affected by excess body weight has reached high values in our geographical area. It is thus justified to initiate screening activities for the early detection and adequate treatment of the modifiable cardiometabolic risk factors, contributing to the prevention of long-term complications.

Abstract

We studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteo and B. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard - B. b. vulpinus. The peek passage period in autumn migration was reached between the 26th of September to the 6th of October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW. Flight height during autumn migration was mostly at high altitude while in spring migration was more evenly distributed. The most significant activity was recorded in the second time period, between 10:01 and 13:00 (43%).

Abstract

We investigated diurnal raptors movements in the Black Sea basin. Bird migration over the western Black Sea has not been studied properly, scarce data being available mainly by Drost’s paper (1930) thus referring only to the birds from Snakes Island, and few new data collected during more recent research expeditions. The study of migration over large water bodies is a very complex task, due to the difficulty of reaching these areas; observations in this paper were made from research vessels and offshore oil rigs. Our data together with previously published information provides a new insight into bird migration routes over the Black Sea. Species observed across the Black Sea basin followed routes that are part of Via Pontica Corridor and Trans-Caucasian Corridor. The aim of this paper is to have a clearer image of the migration phenomenon in this area, such data are important for management and conservation of migratory birds.
