Da Silva et al., 2008). Their larvae may be nektonic and live in a variety of coastal habitats, estuaries, coastal lagoons, open coasts, and river deltas (Laudien et al., 2007. Meerhoff et al., 2016).. Recent phylogenetic studies (Kon et al., 2007) have shown that the cephalochordate subphylum (Schubert et al., 2006) is divided into 3 genera: Branchiostoma Costa 1834 with...

Haematopoiesis in the European common toad Bufo bufo (Linnaeus, 1758): new methodological insights to study general, seasonal, and sexual haematopoietic. Reduction in the amphibian population is a global threat.. Johansson et al., 2006). Haematology has an important role in the physiological evaluation of animals (Campbell, 1998). Haematological parameters allow detection of changes in physiological, pathological, ecological, or environmental conditions in...

Many factors cause the study of diet to be of the utmost importance. It brings a better understanding of the nature of potential competitive interactions between sympatric species (Jaksic et al., 1992;. The study of the diet of insectivorous mammals has been the subject of several works. For instance, we can cite the case of the mole of Europe (Beolchini...

Studies on organisms living in the specific conditions of brackish waters provide a basis for understanding biological structures and the functioning dynamics of these biocoenoses. In addition, as a key link in the food chain, zooplankton are responsible for maintaining good water quality by controlling the growth of phytoplankton (Paturej and Kruk, 2011). Zooplankton research on Vistula Lagoon began in...

The prevalence and genetic diversity of feline immunodeficiency virus and feline leukemia virus among stray cats in Harbin, China. Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are typical retroviruses that are transmitted horizontally among felines (Lutz et al., 2009).. FIV was first described as an infectious disease of domestic cats in 1986 (Bendinelli et al., 1995. Bachmann et...

Biochemical blood parameters and hormone levels of foraging, nesting, and injured loggerhead sea turtles (Caretta caretta) in Turkey. Extensive conservation efforts have been made to protect sea turtles in the last three decades in the Mediterranean, but most of the threats such as coastal development, incidental catch, collision with marine vehicles, and intentional killings remain (Casale and Margaritoulis 2010, Başkale...

Effects of genetic relatedness, spatial distance, and context on intraspecific aggression in the red wood ant Formica pratensis (Hymenoptera: Formicidae). Nestmate discrimination in ants is dominantly mediated by the use of chemical cues, cuticular hydrocarbons (CHCs) located on the surface of the body (Torres et al., 2007. Martin et al., 2008. Chapuisat et al., 2005), helping them to decide to...

Composition and structure of soil fauna community in the Dexing Copper Mine tailings pool after revegetation. With the disposal of the tailings, the original ecosystem of the tailings pool is seriously affected (Chen et al., 2016). Many toxic elements accumulate in the tailings pool, and there is no vegetation cover on the surface, which can lead to severe pollution and...

Lichens in the nests of European starling Sturnus vulgaris serve a mate attraction rather than insecticidal function. Nest building is a key process in the life of birds (Hansell, 2000). Materials used to build nests have multiple functions that may have important consequences on a bird’s fitness (Mainwaring et al., 2014). However, the presence of other nest materials is more...

Influence of tree thinning on abundance and survival probability of small rodents in a natural deciduous forest. In particular, urbanization, road construction, forest management, and forest fires have been major disturbance factors in the last several decades (Lee et al., 2017. Son et al., 2017). Ecologically oriented approaches have been used for the conservation and protection of biodiversity (Gasperini et...

Diet composition and prey diversity of Tengmalm’s owl Aegolius funereus (Linnaeus, 1758. Their diet has been well documented for most species, especially in central and northern parts of the continent (e.g., Uttendörfer, 1952. However, despite such a large number of studies, feeding habits of breeding owl species are still unknown for many vast regions (e.g., mountain ranges). One species that...
