“…Th e method of morphophysiological indicators (MMPI) (Schwartz et al, 1968) was used to study small rodents' response to environmental changes. Th is method is widely used in practical ecology and bioindication to analyze the potential impacts of varying environment on the organism (Pyastolova, 1987;Gashev, 2000;Olenev, Grigorkina, 2019;and others). To describe the animals' external characteristics, body indices were used (ratios between the lengths of various parts of the body, such as tail, foot, ear, and the length of the body).…”

The article provides a survey of the mammalian fauna and ecology in different habitats across the city of Tashkent that vary in the degree of urbanization. The current mammalian fauna of Tashkent is represented by 32 species; during the city’s development, 9 species have disappeared from the place, either through an anthropogenic impact or having been forced out by alien species. The urban mammalian fauna has increased through arrival of five new invasive species. With the ongoing urbanization, the species diversity of small-sized mammals is decreasing, while their numbers are growing, resulting in simplification of the structure of small mammals’ urban communities and lowering of their biodiversity. The urbanization does not impact the age and sex structure of the house mouse population noticeably. The urban population shows a productivity 1.7 times higher than the wild populations, which is a compensatory response to the relatively high embryonic mortality that is almost totally absent in natural populations. Differences in the morphophysiological indicators of the house mouse synanthropic population and those of populations in the wild are an adaptive response to anthropogenic impact, which appears in the form of more rapid growth, a higher metabolism, exchange of energies, and overall stress load on the rodents in urban biocoenoses. The study showed that the skulls of urban animals grow more rapidly than those of wild mice, while their proportions change following the development pattern of juvenile mice, which suggests that individuals from the Tashkent population can be referred to as rapidly growing animals, with outdoor individuals showing greater relative cranial parameters.

In order to explore the impact of ecological environmental protection measures on ecological functional zones and promote the sustainable development of ecology, the ecological functional zone of a hilly region in south China is taken as the research object in this study. Combined with the data of ecological environment and land use type in the past ten years, the ecological function index (water conservation index), ecological structure status (forest coverage, grassland coverage, and ratio of wetland in waters), and ecological stress situation (ratio of cultivated land to construction land) are analyzed to reflect the ecological status of ecological functional zones. The results show that in the past ten years, the water conservation index and forest coverage rate in the studied area have been improved significantly, and the ecological condition has become better, which indicates that ecological protection measures such as returning farmland to forest and closing mountains for forest cultivation can improve the ecological environment of ecological functional zones and contribute to the sustainable development of ecology.
