Abstract
Ecosystem change is an everyday reality, and assessment of its ability to provide men with products and services of the ecosystem (fresh water, climate, soil fertility, etc.), which are necessary for human welfare, is an urgent applied issue. The question as to “whether changes in the loss of biological diversity will affect the functioning of local ecosystems” is attracting increasing attention. In this first paper, we consider modern approaches to ecosystem monitoring. The concept of historical and novel ecosystems, ecosystem resilience, threshold effects, theory-driven restoration, and social–ecological considerations are reviewed. The principles of indication, requirements for indicators, possibilities, and prospects for the use of small mammals as indicators of the dynamics of local ecosystems are considered.

Abstract
Quinqueserialis quinqueserialis (Trematoda: Notocotilidae) is a widespread species in the Holarctic that parasitizes the cecum of the muskrat. The results of micromorphological studies of parenchymal organs of the muskrat at a high intensity of invasion by Q. quinqueserialis are presented for the first time. In infected muskrats, activation of the B-cell and macrophage components of the immune system was established against the background of inhibition of granulocytic reactions in the spleen. Various types of dystrophies were detected in the liver, and, with the formation of functional maladjustment of the organ, inflammatory changes were recorded in the kidneys with signs of alterative, necrobiotic processes. The development of destructive pathomorphological processes indicates the participation of trematodes in the pathogenesis of this parasitosis. The obtained data provide new information for understanding the functions of the lymphoid and parenchymal organs in wild rodents with trematodosis.
摘要 Quinqueserialis quinqueserialis（吸虫纲：Notocotilidae）是一种广泛分布于北极地区的物种，寄生于麝鼠的盲肠。本文首次介绍了在麝鼠受到Q. quinqueserialis高强度入侵时对其实质器官进行微形态学研究的结果。在受感染的麝鼠体内，免疫系统中的 B 细胞和巨噬细胞成分被激活，而脾脏中的粒细胞反应受到抑制。在肝脏中发现了各种类型的萎缩，随着器官功能失调的形成，在肾脏中记录到了炎症变化，并伴有改变和坏死过程的迹象。破坏性病理形态过程的发展表明，吸虫参与了这种寄生虫病的发病机制。所获得的数据为了解患有吸虫病的野生啮齿动物的淋巴器官和实质器官的功能提供了新的信息。

Abstract
For two years, the contribution of fungi and bacteria to the process of net ammonification in soddy-podzolic soil of the sorrel–blueberry birch forest of Yaroslavl oblast was determined using inhibitory analysis. It was established that the litter is characterized by equal participation of fungi and bacteria in this process. In the humus horizon, a slight excess of fungi over bacteria was noted in years of normal moisture and there was a clear dominance of fungi in dry years. In the eluvial part of the profile, the close contribution of these groups was noted, with an insignificant prevalence of one of them over the years of study. The maximum air temperature is able to change the seasonal dynamics of the abundance of saprotrophic fungi in the soil and to some extent form the generic structure of the mycobiota in the horizons of the soil profile of the birch forest.

Abstract
Long-term monitoring of the abundance of the steppe polecat (Mustela eversmanii) in Chelyabinsk oblast is considered. The analysis of the abundance dynamics of Mustelidae was carried out on the basis of monitoring data using the method of winter accounting (WA) conducted annually. Over the past few years, the steppe polecat has not been registered during accounting work in the mountain taiga; i.e., its numbers are either extremely low, or it has disappeared completely. In forest–steppe territories for 12 years, from 2008 to 2020, the abundance of polecats decreased almost 90 times, from 3058 to 34 individuals. The data on the number of the main prey species of the steppe polecat, two species of ground squirrels (Spermophilus major and Spermophilus pygmaeus) and the groundhog (Marmota bobak), are presented. The hypothesis of the possible influence of the American mink on the numbers of the steppe polecat is considered.
