Winter path accountancy of video game animals (3MU) was recommended by the Ìglavohotaî as the main blog post-harvest to determine the number of pets in the marshes over huge areas.
It is hung on a pre-planned straight routes equally, covering various sorts of searching premises and also gives an overall picture of the spatial placement of hunting animals. I wish to emphasize the mistakes in the processing of accountancy information. The wintertime route checking is based upon counting the variety of tracks of creatures of different species going across development « obstructed » on the very first day of the course line.
A document of accounts(PU)loved one variety of pets– variety of trace varieties at 10 kilometres of the path account. It is defined as the variety of traces encountered types, separated by the length of the course multiplied by 10 km. Neutrality identify the absolute number of pets(density environment people per 1 km2 or 1000 hectares) and also the dependability of the gotten information relies on the quality of the strategies applied and the appropriate selection of the preliminary data for computation formulas.
It is believed that the greater the number of traces of the beast will certainly be experienced on the route, the higher the thickness in the location. It is usually accepted that the number of tracks going across the course line is symmetrical to the variety of pets of this species, depending upon its activity as well as level of diurnal variants in these certain scenarios.
The computation of the absolute variety of pets based upon making use of formula A. N. Formozov( 1932): R=S/dm(1) is the population thickness of animals(R)equivalent to the quotient from separating the number come across on the route people (S) in the location of the strip-based(dm, where m– length account of the course in km, d is the data transfer of the account equivalent to the size of the everyday program of the beast in km).
When the overall reasoning of the formula A. N. Formozov there is naturally 2 unidentified factors: S– exactly how to relocate from the quantity of traces of N to the number of people S; d– exactly how to identify the width of the stripe account(which is the perspective of length of the day-to-day course of the beast ). Modern approaches of determining absolute wealth utilizing designed scalar proportion: P=PU – K(2), (where K=1,57/ d– scalar proportion)is a lot more misshapes the results and also makes a Titanic job of specialists in Russia in the « monkey work ». Why? Will certainly attempt to figure this out. Passing along the planned linear course accounting clerk encounters «indicators of animals, taping the number and also instructions of crossings.
Each new encounter traces of the monster on your route, various handwriting from the other, implies the day-to-day going across of the area of its habitat. The record-Keeper does not handle the length of the day-to-day course of the beast:– d(it’s neither here nor there ), and from everyday task– n(setup and tortuosity of the track ), is highly variable, from weather changes, sex, age as well as physical condition of the animal. Daily monster resolves them in the land might be weak or extremely confusing winding.
Contoured heritage diurnal pet(environment), normally has the form of an irregular ellipse. Area the route can cross the story of the beast at any factor and also any type of valid instructions no matter its form and also area on the ground. If the same habitat with the animal (e.g. foxes )to cross at the very same point in numerous instructions, along with different length sections of the course within it, after that their math average will certainly be close to the diameter D of equal habitat with individuals in the form of a circle(Gusev, 1965 ). Each section in the figure (as well as the path)goes across a number of times the tradition of the Fox. The variety of junctions within a section by the index of day-to-day activity.
The arithmetic standard of the complete task rate mirrors the typical day-to-day n. The indication might be more improved by statistical analysis. These basic indicators essential for estimations of absolute wealth are identified concurrently with accomplishing route surveys. While tracking the monster does not need the size of a daily program(established by counting the variety of its own actions), as well as the rate of his daily activity– n.
For the registration of the sinuosity of the track is important using modern satellite Navigator. When developing the average everyday activity of the monster n you can conveniently relocate from track– N to the variety of individuals of S, splitting the task total variety of registered route traces: S=N/N For a good answer to the question: « How to establish the size of the stripe account? », please refer to the schematic drawing, where it follows that the conference traces of the monster on the account the route A– B takes place just at the junction of the area of its habitat. The locations of environment might overlap with a path in any place: at the facility (1, 6), left( 3, 5, 7, 8)right(2, 4), including tracks, hardly on course( 2, 5, 8).
Nonetheless, if you narrowed the strip of account, equal to the ordinary diameter of the home variety of individuals (D), most of registered sites will be outside, which will certainly cause an overestimation of the computed information. When wide band based(2D ), the opposite, there is underreporting due to underreporting environments are not crossed by the course, however remaining in the band account. Empirically(Jackson, 2005 )it was established that the most affordable mistake provides the ordinary width of the tape audit for 1.5 D.
After alternative in formula(1 )d (size of the day-to-day training course of the beast) 1.5 D square account tape can be determined as 1.5 Dm. After changing in the numerator of the formula A. N. Formozov(1)S(variety of species experienced on the course )by the proportion N/N as well as the (lane keeping )the length of the everyday training course of the beast d(transmission capacity )on the size of its hunting grounds of 1.5 D, it has actually obtained the most excellent type(3): R=N/1,5 Dmn (3); where: R– thickness residence individuals; N– the variety of traces; 1.5 D — width account strip; m is the length of the route; n — the average daily activity of people. To enhance the precision of inventory, to tracking day-to-day track of the beast happened concurrently with the route studies in one day-to-day activity. This removes the need to develop the length of its daily track variety of its own steps.
They just need to pass along the track of the monster with the consisted of Navigator, and also fix its arrangement. Recognition of day-to-day activity trace pets relocating effortlessly from videotaped traces by the variety of people, and on the sizes of diurnal habitats supply a clear understanding right into account the width of the strip. Our propositions do not make huge adjustments to the company of 3MU.
But using Centrokhotkontrol the recommended approach as well as a brand-new formula for calculating the bookkeeping leads to the elimination of systematic and also organizational monitorings by Y. Dunishenko, can raise the reputation of the faceshield as the primary method of identifying after the video game populations of video game animals in large regions.
