The aim of this work was to identify and analyze the ontogenetic and spatial structure of steppe plant Clausia aprica (Stephan) Korn.-Tr. (Brassicaceae) cenopopulations at the border of distribution. The study of cenopopulations and their habitat conditions was conducted at 2006–2021 in Samara, Volgograd, and Orenburg Oblasts (Russian Federation). For the first time determined the polyvariance of development of individuals, the duration of ontogenetic stages and complete ontogenesis, peculiarities of spatial location and evaluation of running window methods.

Found only in mountainous areas along the borders of Tennessee, North Carolina, and Virginia, populations of the yonahlossee are considered to be rare and local throughout their range. Genetic differentiation among populations of any species is usually attributable to long-standing, extrinsic barriers to gene flow.

Abstract:
The species Turnera subulata Sm. (Turneraceae) has a wide distribution in Brazil, being used for ornamental, medicinal and food purposes. Despite this, information on the ecology of the species is still scarce. Thus, the present work aimed to analyze the population structure of the species T. subulata in an area of the municipality of Itabaiana, Sergipe. In the study area, 10 plots of 1m² were plotted and the number of individuals was counted and the height and diameter of the stem were measured at their ground height. With these data, the density and spatial dispersion of Morisita were calcul

Abstract:
During our studies, it was fetched out that on the territory of the Tungusky reserve, which is representative of Southern Evenkia, there are 4 species of the genus Cypripedium: C. calceolus, C. macranthon, C. guttatum and C.×ventricosum, confined primarily to warm slopes of hills covered with larch forests. For population-biological studies, 3 model coenopopulations of each species were selected. The ontogenetic spectra of most of the studied populations are vegetatively oriented, although all species also have coenopopulations with a generatively oriented spectrum.

Abstract:
Smelts play a key role in the pelagic ecosystem of large lakes in northern Europe and North America. In numbers, they often dominate the open water. In large lakes in Scandinavia (including Finland), European smelt (Osmerus eperlanus L.), a cold-water glacial relict, is commonly the most important prey for piscivorous fish species, but also acts by ontogenetic shifts as a predator on zoo-plankton, small crustaceans, fish larvae, mysids and occasionally – with increasing size - fish. Furthermore, the large numbers of smelt in the open water are important competitors to other planktivorous fish.

Condition being studied: Many definitions of physical literacy refer to a lifelong participation in physical activity, presenting multiple benefits for people's health. Therefore, many organizations (universities, government entities, research groups) in different countries promote interventions for its development. However, the approach to these interventio

Abstract:
Genetic resistance is often the least expensive, most effective, and ecologically-sound method of disease control. It is becoming apparent that plant genomes contain large numbers of disease resistance genes. However, the numbers of different resistance specificities within a genepool and the genetic mechanisms generating diversity are poorly understood. Our objectives were to characterize diversity in clusters of resistance genes in wild progenitors of cultivated lettuce in Israel and California in comparison to diversity within cultivated lettuce, and to determine the extent of gene flow, re

Birds are an important component of park ecosystems. They also have a tremendous following among the public, and many parks provide information on the status and long-term trends of bird populations through their interpretive programs. With habitat vanishing, ecosystems being altered, and bird populations declining, we proposed monitoring bird communities on National Park Service lands within the Heartland Inventory and Monitoring Network. Monitoring breeding birds helps park managers protect birds by providing them with information about the current status and long-term trends in bird populat

Abstract:
This article aims to discuss the scope and value of the conventional metrics used to assess and compare levels of ageing between different populations. The age brackets for classifying if the population is ageing or aged are typically based on chronological age and are very close to the stages of the economic tripartite life cycle: the school/education phase; the labour market participation phase; the retirement phase. Those conventional metrics produce distortions in capturing the levels of demographic ageing. If the change in the age structure is rooted in social development, not in a social

Abstract:
Arctic and alpine rare plant species populate wave-splashed rocky shorelines of Isle Royale National Park, where summer temperatures are moderated by Lake Superior. Using data from the mid-1990s and resurvey data from 1998, 2003, and 2016, we examined trajectories of change in occurrence for 25 species at 28 sites coincident with rising lake levels that followed a period of sustained low levels. We analyzed changes in site occupancy of species individually and by functional, geographic, and microhabitat groupings. We also assessed change in population structure for four focal species: Saxifrag
