The objective of this study was to classify the lands of a micro-watershed located in the Atlantic forest biome, in a region of rough relief, in the use capacity system using geotechnology resources and indicate uses for the lands according to their suitability. The theoretical basis of the Manual for Utilitarian Survey and Classification of Land in the Use Capacity System with adaptations for areas of rough relief was adopted. The study was carried out from the survey of topographic information to construct the altimetric map of the watershed, followed by the survey of the physical environment, especially water erosion, description of soil profiles and collection of samples. The parameters effective depth, texture, permeability, slope, erosion, fertility, and land use were evaluated. Based on the pedological data and on the use of applied geotechnology, the soil map was created, and the lands of the watershed were classified and mapped in the use capacity system. After interpretation of the survey products, it was verified that in rough relief, slope is the predominant factor to determine the classes of land use, as it outweighs the other parameters evaluated. Land classification land with the use capacity system promotes optimization in the use of areas with agricultural areas and preservation of those destined for conservation.

X-rays of 438 North American specimens of the Myoxocephalus quadricornis-complex (Cottidae) showed mean vertebral counts (including urostyle) of 38.433 in the deepwater sculpin which inhabits inland continental lakes; 41.097 in the freshwater relict in lakes on Victoria Island, Northwest Territories; 41.417 in newly discovered freshwater relicts in Nauyuk, Stanwell-Fletcher, and Sophia lakes, Northwest Territories; and 41.821 in the coastal fourhorn sculpin living in brackish and marine coastal waters and certain adjacent fresh waters. Except for the Victoria and the three lake relicts, the vertebral means of all pairs of these groups differed at P <.01 or <.001. Of the coastal fourhorn sculpin and the deepwater sculpin 91% are identifiable using only vertebral number, of the Victoria relict and the deepwater sculpin 68%, and of the Victoria relict and the coastal fourhorn only 10%.Vertebral counts alone permit recognition of the deepwater sculpin as a subspecies, Myoxocephalus quadricornis thompsonii Girard, 1852, distinct from the arctic coastal fourhorn sculpin provisionally referred to M. q. hexacornis (Richardson, 1823) and suggest classification of the Victoria Island, Nauyuk, Stanwell–Fletcher, and Sophia lake relicts with the coastal form, rather than with the deepwater sculpin. Relicts in the latter three lakes are suggested to be postglacial in origin.

Buildings in industry, mining, transportation and for personal and commercial activities cover increasingly more valuable agricultural land. The increase of sub-urbanization and vehicular traffic and the spread of malls and other kinds of investments are causing serious harm for not only to human society, but to a whole national economy as well.The law on agricultural land (1994:LV) contains legal rules for the preservation, use and classification of agricultural land. These rules define the temporary or permanent use of land for agricultural and non-agricultural purposes; the scale of the land-protection fee and the rules of the process on cases in which land is used for non-agricultural purposes without the consent of the land registry. In the field of land classification, the law prescribes the regulations which are to be followed in order to define the net income of agricultural land in Golden Crowns.Hungarian land protection rules are unique in the European Union, because only few member-states have similar laws to ours. Community law does not regulate the member states, except in the case of land classification, because this is the basis of the tax paid on the agricultural lands, but even here, there are differences among the states.
