The correlation between dominance level and local species richness: An analysis of the underlying causes by the example of the West Caucasian arboreal and avian communities

Species separation in artiodactyl communities by the criterion of territorialism: The hypothesis of olfactory exclusion
Biology Bulletin Reviews - Tập 7 - Trang 26-36 - 2017
The interspecies distinctions were determined in two artiodactyl communities from geographically distant populations by means of discriminant analysis of four traits: altitude, mean body mass, mean group size, and territorialism. These communities inhabit similar landscapes of the Altai and Himalayas. They are formed by species with different territorial systems (year-round and seasonal), and also...... hiện toàn bộ
Supercolony of Dolichoderus quadripunctatus Linnaeus (Hymenoptera, Formicidae)
Biology Bulletin Reviews - Tập 8 - Trang 449-462 - 2018
Three colonies of Dolichoderus quadripunctatus of different sizes were revealed in the area of Kiev in June–July 2015. One of them was represented by a supercolony (secondary federation) located in walnut (Juglans regia) and apple tree (Malus domestica) plantations. The two true colonies include ten and three central nests, while the supercolony consists of 134 nests. Integration at the level of p...... hiện toàn bộ
Phosphorilated Polyprenols as Universal Agents of Viral Reproduction Suppression
Biology Bulletin Reviews - Tập 12 - Trang 609-624 - 2022
This review is focused on polyprenyl phosphatis (PPFs) (phosphorilated polyprenols), a unique class of natural compounds with a wide spectrum of biological activity. The main emphasis is put on their antiviral properties that were studied in numerous in vitro and in vivo experiments. The results formed the basis for the development of new drugs containing PPFs as the active substance. These drugs,...... hiện toàn bộ
Interpopulation variability of endocrine and metabolic response to cold stress in northern red-backed vole (Myodes rutilus)
Biology Bulletin Reviews - Tập 7 - Trang 56-63 - 2017
The stresses faced by animals in nature are reflected in the adrenal cortex functional activity. It is possible to expect that the basal concentrations of glucocorticoid hormones will be increased in animals inhabiting unfavorable conditions (and correspondingly the value of the adrenocortical reaction to acute stress will be decreased). Since mobilization of the organism resources for the compens...... hiện toàn bộ
Selective feeding in fish: Effect of feeding and defensive motivations evoked by natural odors
Biology Bulletin Reviews - Tập 6 - Trang 70-83 - 2016
The effect of feeding and defensive motivations evoked by natural olfactory signals (food odor, alarm pheromone) on the choice and consumption of food items of different colors and tastes were examined in fish (koi Cyprinus carpio, roach Rutilus rutilus). Agar-agar pellets of red and green color containing one of the amino acids (glycine, L-proline, L-alanine; in the concentration of 0.1 M) were s...... hiện toàn bộ
Mineral nutrition of plants inoculated with plant growth-promoting rhizobacteria of Pseudomonas genus
Biology Bulletin Reviews - Tập 2 - Trang 487-499 - 2012
The paper considers how the inoculation with the growth-promoting rhizobacteria of the Pseudomonas genus affects the mineral nutrition and plant uptake nutrients from the soil. The bacteria are ascertained to increase the uptake of nutrients by plants mainly due to the direct effects on their accessibility in soil and growth in the absorptive and excretory activities of the root system associated ...... hiện toàn bộ
Seasonal changes in hippocampus size and spatial behavior in mammals and birds
Biology Bulletin Reviews - Tập 1 - Trang 279-288 - 2011
The hippocampus of mammals and birds is involved in the processing of spatial information about their environment. Its size positively correlates with spatial activity with home range size in particularly if closely related species in both mammals and birds are compared. Can this pattern also be seen in ontogenesis, the individual life of animals, under cyclic and seasonal changes in behavior that...... hiện toàn bộ
Biogeographical consequences of natural and anthropogenic climate changes
Biology Bulletin Reviews - - 2012
Consequences of “rapid” climate changes (comparable to the characteristic time with the changes of biota, ecosystems, and their successions) are discussed in the context of the revelation of a new phenomenology in biogeography. The influence of climatic changes on biogeographic boundaries, the status of biogeographic borders, and possibilities of the new biogeographic regionalization of Russia is ...... hiện toàn bộ
Arctic Geese (Anser) and brants (Branta) of Eurasia: An analysis of factors that control population dynamics and geographical ranges
Biology Bulletin Reviews - Tập 6 - Trang 436-455 - 2016
Geese (Anser) and brants (Branta) are important elements of Arctic ecosystems, which attract the interest of biologists around the world. Due to this interest, a great amount of empirical data has been accumulated, including detailed descriptions of the morphology, nesting characteristics, trophic ecology, behavior, migrations, population geography, and other features of Arctic geese and brants.
