Not just spruces, but a diverse, mixed forest, including sycamore trees, beeches and rowan trees - this is how the forest landscape of the Tatra Mountains is changing, having been destroyed in recent years by hurricane mountain winds and spruce bark beetle outbreak. Professor Jerzy Szwagrzyk from the University of Agriculture in Kraków investigates this process.
Nearly 90 percent of mussels and aquatic snails and 3.3 million fish have died in the lower Oder. Across the entire affected stretch of the river, the estimated fish mortality was 1,650 tons, a 60 percent decline from pre-disaster levels. Researchers presented the summary of the effects of last year's Oder environmental disaster in the journal Science of the Total Environment.
Researchers from the Faculty of Biology of the Jagiellonian University have found a method that allows scientists to quickly obtain bone tissue cells ready for transplants or other uses in bone regeneration therapies.
A whopping 5,000 Baltic sturgeon fry were released into the Drawa River this autumn by employees of the Drawa National Park together and their colleagues from Germany. This is part of a program to restore the population Baltic sturgeon fry which was considered ‘extinct’.
Pliosaurs - a group of plesiosaurs - reached great sizes much earlier than previously thought, according to research by an international team of scientists including a researcher from the Polish Academy of Sciences. The discovery sheds new light on the course of the evolution of the huge marine predators.
The insectivorous sundew helps scientists destroy the 'armour' that protects bacteria from antibiotics. Even the most resistant bacteria on catheters or dressing materials have a much lower chance of growing and lose their antibiotic-resistant coating when treated with an extract from selected plants.
Scientists have discovered a new species of fungus, Formicomyces microglobosus. It was isolated from the infrabuccal pouch of the red wood ant Formica polyctena, a population of which lives in the forests near Warsaw.
In the early stage of pregnancy, the dialogue between the developing embryo and the mother is one of the key factors determining the success of the embryo implantation process in the uterus. Scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn have discovered another relationship that helps to understand this complicated process.
Polish researchers from the University of Warsaw and the Polish Academy of Sciences have explained the mysterious coexistence of animal and plant forms in the environment of coastal sea shallows from approximately 427 million years ago.
The areas of present-day south-eastern Poland used to be covered by a shallow sea. But apart from fossil fish, invertebrates and plants, bird remains are also sometimes found. Thanks to these few officially known finds, we know that species related to today's passerines, as well as grouses, hoopoes, hawks and... hummingbirds lived here.
