Evidence of the negative impact of hydraulic construction, embanking of floodplains, channelizing of rivers, agriculture, and other anthropogenic impacts is presented. A special role is played by climate change, which leads to a decrease in flood inundation, drying and overgrowing of water bodies, and their eutrophication. The authors suggest criteria to choose correct indicators that can testify not only to special stages of water body succession (e.g., vegetation) or its trophic status (zooplankton), but also to the long-term effects of anthropogenic and climatic changes. As a recommendation, it is proposed not to consider water bodies separately, but to assess the whole waterscapes and use the change in β-diversity as an indicator. Further conservation strategies can be based on the approaches of the Red List of Ecosystems of the International Union for Conservation of Nature and Natural Resources (IUCN), which will help to draw attention to the problem. The key role for the conservation of floodplain water bodies should be played by territorial protection measures, up to the development of a separate category for small water bodies.</p>","PeriodicalId":9047,"journal":{"name":"Biology Bulletin Reviews","volume":"302 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140610182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Role of Cultural Traditions in Ecological Niche Partitioning in Cetaceans","authors":"O. A. Filatova","doi":"10.1134/s2079086424010043","DOIUrl":"https://doi.org/10.1134/s2079086424010043","url":null,"abstract":"<h3 data-test=\"abstract-sub-heading\">Abstract</h3><p>Ecological niche partitioning is a process that allows organisms to achieve differences in resource use to reduce competition. Niche partitioning is traditionally viewed as a result of modification of genetically inherited traits through the process of adaptive evolution. However, in social animals with developed cognitive abilities, a significant portion of behavioral patterns is transmitted not genetically, but through social learning. Complex sets of behavioral patterns transmitted through social learning are called cultural traditions. The partitioning of ecological niches in cetaceans is most often considered in the context of morphological adaptations: changes in size, skull shape, and the structure of the filtering apparatus. The role of cultural traditions in niche partitioning is still poorly understood, but it is an important and promising area of research, as it provides a novel approach to the ability of animals to change their behavior in order to exploit the environment more efficiently. The main advantage of traditions over genetically inherited behavioral patterns is the ability to change quickly and spread rapidly in a population. Estimating the role of cultural traditions in ecological niche partitioning would highlight the significance of behavior plasticity and social learning in the evolution of animal intelligence. Ecological niche partitioning through the rapidly changing and rapidly spreading behavioral adaptations in the population, allowing to adapt quickly to changes in the environment, could provide a significant evolutionary advantage, which could lead to the development of a relatively high level of intelligence in cetaceans.</p>","PeriodicalId":9047,"journal":{"name":"Biology Bulletin Reviews","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The details of this event remain poorly understood; in particular, a great variety of known neurotransmitter substances requires an explanation. We analyze the homologs of neuronal glutamate and gamma-aminobutyric acid (GABA) receptors in Placozoa (animals without a nervous system, but possessing the mobility and behavior). Phylogenetic analysis and comparison of amino acid residues responsible for a ligand specificity demonstrated that these Placozoan receptors are unexpectedly numerous, diverse, and evolutionarily dynamic, and by all these traits, they rather resemble the olfactory receptors of higher animals.

This was in conflict with the ideas existing at that time about the impossibility of the formation of organized communities or multicellular organisms by prokaryotes. It was believed that the formation of multicellular organisms and any communities with developed communication requires a high structural complexity of the elements. Bacteria were considered as solitary or colonial organisms not having sufficient complexity. However, direct observation of their accumulations revealed signs of highly organized communities comparable in their integrity to organisms. This forces a different approach to the nature of the emergence of communities and the sources of their complexity.

This neurodegenerative disease is characterized by a progressive course and belongs to a group of socially significant diseases. There are several hypotheses for the development of AD: the tau hypothesis, the amyloid hypothesis, the cholinergic hypothesis, the hypotheses of oxidative stress and inflammation. The absence of a generally accepted understanding of the etiology and pathogenesis of AD prevents the development of new efficient methods for its treatment and prevention. In clinical practice, cholinesterase inhibitors that alleviate the symptoms of the disease but do not affect its course are widely used. In 2021, a drug for pathogenetic therapy of AD (aducanumab), which contributes to a decrease in the content of amyloid-β peptide (Aβ) in the brain of patients, was for the first time approved. The effect on human serum albumin (HSA), which carries 90% of Aβ in the blood serum and 40–90% of Aβ in the cerebrospinal fluid, is another promising approach to the treatment of AD aimed at removing Aβ from the patient’s central nervous system. In clinical practice, plasmapheresis with a replacement of one’s own HSA with a purified therapeutic albumin preparation has already been tested and demonstrated its efficiency. The enhancement of the interaction of HSA with Aβ through the effect of exogenous and endogenous HSA ligands (such as serotonin, ibuprofen, and some unsaturated fatty acids) is another variant of this approach. The studies in vivo confirm the association of this group of ligands with the pathogenesis of AD. The listed substances belong to well-studied natural metabolites or drugs, which significantly simplifies the development of new methods of therapy and prevention of AD using them. In general, a new direction of scientific studies devoted to the study of HSA as a carrier and depot of Aβ in the blood and cerebrospinal fluid will allow us to expand our understanding of Aβ metabolism and its role in the pathogenesis of AD.</p>","PeriodicalId":9047,"journal":{"name":"Biology Bulletin Reviews","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140316626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stage structure of a local population has been observed on permanent plots in the alpine belt of the Northwestern Caucasus annually for 13 years (2009–2021), accumulating data of the “identified individuals from unknown parents” type. The latter circumstance has predetermined what is called reproductive uncertainty in the terminology of matrix models for discrete-structured population dynamics and means that the annual recruitment rates inherent in the groups of generative plants and final-flowering generative plants cannot be calibrated in a unique way. As a result, instead of the annual values of the asymptotic growth rate, the model gives only certain ranges of their values that vary from year to year, corresponding to the data. This introduces both technical difficulties and uncertainty in the viability forecast based on the asymptotic growth rates. A well-known alternative approach is to estimate the stochastic growth rate λ_S, but only artificial modes of randomness involved in the calculation of λ_S have been proposed in the literature. Our realistic model of randomness is related to variations in weather and microclimatic conditions of the habitat. It is reconstructed from a fairly long (60 years) time series of the weather indicator. Using this realistic model in Monte Carlo calculations of λ_S, we have obtained a more reliable and accurate estimate of the stochastic growth rate.</p>","PeriodicalId":9047,"journal":{"name":"Biology Bulletin Reviews","volume":"129 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140316627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a part of the study on bird communities, changes in bird abundance during the secondary succession of a cleared mossy pine woodland in southwestern Belarus were investigated. The purpose of the work was to determine the interannual dynamics of bird species abundance and to assess the variability of individual species abundance during the secondary succession of the mossy pine woodland. The material was collected in 2000–2019. Line transects were set to conduct bird counts in ecosystems at different stages of succession. For the data processing, generally accepted methods of statistical analysis were used. The species diversity of birds was found to increase from 8 to 42 species; the overall abundance increased from 171.7 to 587.1 birds/km² during the succession (six stages, from 1 to 90 years in age). The abundance of species (birds/km²) and interannual variability during 11 seasons were determined. The coefficient of variation (CV) was the highest (71.00–82.50%) for species whose abundance did not exceed 1.0 birds/km². The average abundance of species varied considerably, e.g., among passerines at the stage of 80–90 years old from 1.1 birds/km² (Red-breasted Flycatcher) to 153.7 birds/km² (Common Chaffinch). Bird populations with high abundance turned out to be the most stable; for example, at the last two successional stages, the CV of the Common Chaffinch is 6.02 and 7.16%. For species with average abundance, the variability is found to be low or medium (varies from 11.90 to 36.20%); for species with low abundance, the CV varies from 17.68 to 82.50%. All six stages of succession were dominated by nesting migratory birds, which account for 75.0% of the species in the first stage of succession to 52.4% in the fifth and sixth stages. Near and distant migrants form the basis of the bird community at all stages. Populations of sedentary species and distant migrants are more stable than those of near migrants.</p>","PeriodicalId":9047,"journal":{"name":"Biology Bulletin Reviews","volume":"128 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
