Prezentowane wyniki uzyskano w czasie realizacji projektu badawczego dotyczącego różnorodności gatunkowej owadów i grzybów związanych z martwym drewnem w lasach dębowych i sosnowych (realizowanego w latach 2012-2015). Obserwacje prowadzono w Lasach Państwowych w drzewostanach gospodarczych i gospodarczych wyłączonych z zabiegów sanitarnych oraz w Drawieńskim Parku Narodowym. W każdym z wymienionych...
Ptaki mogą szybko reagować zmianami liczebności zarówno na negatywne, jak również korzystne zmiany zachodzące w ekosystemach.

W ramach Monitoringu Ptaków Polski w 21 podprogramach gromadzone są dane dotyczące ok. 162 gatunków ptaków lęgowych. Wskaźnik liczebności pospolitych ptaków...
