Для описания эволюции миграции применялась модель, учитывающая нестационарность окружающей среды [<xref ref-type="bibr" rid="cit3">3</xref>]. В частности, исследовалось дифференциальное уравнение второго порядка с кубической нелинейностью, отрицательной вязкостью и периодическим внешним воздействием. В результате найдены решения, которые не являются, строго говоря, периодическими, но проявляют периодическое поведение на некотором ограниченном промежутке. Выявлены также некоторые зависимости между параметрами модели. Полученные результаты говорят о необходимости уточнения некоторых предполагаемых вариантов поведения решений указанной модели.</p></abstract><trans-abstract xml:lang="en"><p>The author undertakes an attempt to find the numerically prospective periodic solutions near two maximas of resource function in a mathematical model of animal migration. The model considering environments that vary in both space and time was applied to the description of evolution of migration [<xref ref-type="bibr" rid="cit3">3</xref>]. In particular, the differential equation of the second order with cubic nonlinearity, negative viscosity and periodic influence was investigated. Decisions which are not, strictly speaking, periodic are found as a result, but display periodic behaviour on some circumscribed interspace. Some dependence between model parameters was revealed as well. The received results are the establishment for specification of some hypotheses about the behaviour of decisions in the model of animal migration.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическая модель</kwd><kwd>миграции животных</kwd><kwd>периодическое решение</kwd><kwd>ресурсная функция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical model</kwd><kwd>animal migration</kwd><kwd>periodic solution</kwd><kwd>resource function</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Спротт Дж.
