Each animal species selects specific microhabitats for protection, foraging, or micro-climate. To understand the distribution patterns of small mammals on the ground and in the understorey, we investigated the use of microhabitats by small mammals in a deciduous forest of southern Brazil. Ten trap stations with seven capture points were used to sample the following microhabitats: liana, fallen log, ground litter, terrestrial ferns, simple-trunk tree, forked tree, and Piper sp. shrubs. Seven field phases were conducted, each for eight consecutive days, from September 2006 through January 2008. Four species of rodents (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes and Mus musculus) and two species of marsupials (Didelphis albiventris and Gracilinanus microtarsus) were captured. Captured species presented significant differences on their microhabitat use (ANOVA, p = 0.003), particularly between ground and understorey sites. Akodon montensis selected positively terrestrial ferns and trunks, S. angouya selected lianas, D. albiventris selected fallen trunks and Piper sp., and G. microtarsus choose tree trunks and lianas. We demonstrated that the local small-mammal assemblage does select microhabitats, with different types of associations between species and habitats. Besides, there is a strong evidence of habitat selection in order to diminish predation.

Mont St. Hilaire has an area of about 10 km2 covered by sugar maple and beech forest. Longworth traps were used on 46 grids from 1966 to 1976 in the snow-free period, mainly in June. One thousand and fifty-one individuals of 10 species of small mammals were captured. Two-thirds of these were Peromyscus, mainly P. maniculatus. Six female and one male Microtus pennsylvanicus were captured, all at least 1000 m from the nearest grassland, which is the usual habitat of this species.Within the forest the species apparently do not segregate into different habitats. Distribution, as measured by the number of grids on which each species was captured, is a function of total numbers. The relationship holds intraspecifically and interspecifically. Peromyscus (species combined), Clethrionomys gapperi, and Blarina brevicauda varied in June numbers from year to year. The range of variation was greatest for Peromyscus. Numbers of Peromyscus and Clethrionomys did not vary synchronously, and neither showed evidence of a regular periodicity in their fluctuations. Regular periodicity in fluctuations appears to be more prevalent in boreal forest populations than in deciduous forest populations. Some of the relevant factors are discussed.Le Mont Saint-Hilaire a une superficie d'environ 10 km2 et est recouvert d'une forêt d'érables à sucre et de hêtres. On a utilisé des pièges Longworth dans 46 sections d'un quadrillage, de 1966 à 1976, durant la période sans neige, surtout en juin. On a recueilli de cette façon 1051 petits mammifères appartenant à 10 espèces. Les deux-tiers de ces animaux appartiennent au genre Peromyscus, et ce sont surtout des P. maniculatus. Six femelles et un mâle de Microtus pennsylvanicus ont été capturés, tous à au moins 1000 m de la prairie la plus proche, environnement habituel de cette espèce.

Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.
