Understanding the birds’ breeding ecology and behaviour during migration can contribute to their efficient conservation. In this study, we fitted two male geese with 18 g Argos Solar PTTs and one female with a 9.5 g Solar PTT to provide information about their breeding home range, time spent in key stopover and staging sites, and the duration of mi...
The paper describes two new species of feather mites collected from some flycatchers (Passeriformes: Muscicapidae) in Meghalaya, India: Trouessartia thalassina sp. n. (Trouessartiidae) from the Verditer Flycatcher, Eumyias thalassinus (Swainson), and Proterothrix sibillae sp. n. (Proctophyllodidae: Pterodectinae) from the Small Niltava, Niltava mac...
The Romanian hamster Mesocricetus newtoni is endemic to SouthEastern Romania (Dobruja region) and NorthEastern Bulgaria, and prefers steppic, arid, uncultivated habitats, but is also found in alfalfa fields, less often in corn cultures and field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this crypt...
The Romanian hamster Mesocricetus newtoni is a threatened and cryptic species, with a distribution limited to Northeastern Bulgaria and Southeastern Romania (Dobruja region). Current literature does not provide sufficient data regarding diel activities and behavior of this species, especially under field conditions. In this context, one female M. n...
The common hamster Cricetus cricetus is a widespread rodent in the Palearctic region, with a well-documented variation in its fur color, which can vary from white to dark, including true and atypical melanistic and other different color morphs within the typical tricolor pelage. We investigated the occurrence of melanistic forms in common hamsters...
Two new species of feather mites are described from the Rusty-capped Fulvetta Schoeniparus dubius (Hume) (Passeriformes: Pellorneidae) in India (Meghalaya): Proterothrix manolelii Constantinescu sp. n. (Proctophyllodidae: Pterodectinae) and Trouessartia asiatica Constantinescu sp. n. (Trouessartiidae). Proterothrix manolelii belongs to the paradoxo...
All four species of dormice present in Romania are listed as Vulnerable in the Romanian Red Book of Vertebrates and are protected by national laws. Even though they are important bioindicators of the condition of forest habitats, little is known about their distribution.
We reviewed the distribution data for the Romanian dormice species: the Garden...
Major histocompatibility complex (MHC) genes code for key proteins of the adaptive immune system, which present antigens from intra-cellular (MHC class I) and extra-cellular (MHC class II) pathogens. Because of their unprecedented diversity, MHC genes have long been an object of scientific interest, but due to methodological difficulties in genotyp...
Despite the growing list of elements assessed and recognised as environmental and human health hazards, pollution monitoring and mitigation strategies are mandatory only for a limited number of metals, for which ambient air quality limits are defined by national and international policies. In order to overcome this deficiency, and promote cost-effe...
Two new feather mite species of the genus Montesauria Oudemans, 1905, collected from thrushes (Turdidae) in India, are described: Montesauria hernandesi sp. n. from Turdus dissimilis Blyth, 1847 and M. caerulea sp. n. from Myophonus caeruleus (Scopoli, 1786). Both species belong to the merulae species group, being morphologically closest to other t...
Based on species occurrence records of museum collections, published literature, and unpublished records shared by mammalian experts, we compiled a distribution database for 59 terrestrial mammals populating the extensively protected Dobrogea Region of Romania. The spatial patterns of mammal distribution and diversity was evaluated and systematic c...

Biomonitoring, i.e. using plant species for measuring pollution levels, has been previously explored in several locations using various protocols and organisms in the search for effective strategies and practices for monitoring and reducing the levels of pollution.
Here we present a tested and functional cost-effective method of using the foliar ac...
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 2662 individuals. We highlighted the seasonal and diurnal peak passage, flight directi...
We investigated diurnal raptors movements in Black Sea basin. Bird migration over the westerns side of the Black Sea has not been studied properly, scarce data being available mainly by work of Drost (1930) thus referring only to the birds from Snakes Island, and few new data collected during more recent research expeditions. The study of migration...
A new species of the feather mite genus Proterothrix (Proctophyllodidae: Pterodectinae) is described from the Large Niltava Niltava grandis (Blyth) (Passeriformes, Muscicapidae) in northeast India (Meghalaya, Jaintia Hills, Shnongrim village). Proterothrix chachulae Constantinescu, sp. n. differs from all known species of the genus by having in mal...
The paper describes two new species of feather mites collected from the blue-throated blue flycatcher Cyornis rubeculoides (Vigors) (Passeriformes: Muscicapidae) in India (Meghalaya): Trouessartia kharkhanensis Constantinescu et al. sp. nov.

Eurasian Stone-curlew breeds in dry or even arid habitats characterized by low precipitation and many hours of sunshine, with short or cropped vegetation. The total number of breeding pairs in Romania is impossible to asses due to lack of data, but has previously been estimated to 200-400 breeding pairs. Our work features a synthesis of the availab...
The protected area of Vaduri-Pângăraţi lakes is home to many bird species, some of them being of great conservation concern. Closely associated with the natural environment, the presence of a specific plant community plays a very important role in feeding and sheltering birds during the nesting and migration period. To show how the habitat characte...
We performed a rational reconstruction of the relationship between biogeochemistry and the study of ecological productive
systems. A structural and a functional possibility for building biogeochemical integrated models with optimal complexity have
been identified. The conceptual framework was then applied to metals in contaminated areas. Metal mobi...
We investigated the structure of biological communities at ecosystem and landscape scale in four small catchments including in their structure contaminated areas resulted from mining and processing of heavy metals ores. The contaminated hot spots (ecosystems) were mining dumps, tailing dams and areas polluted by atmospheric deposition around a smel...
