The turtle that lived around 215 million years ago in what is now Thailand did not belong to a previously known genus.. It is a proof of a greater diversity of early representatives of this group than previously assumed, demonstrate palaeontologists, including researchers from the Institute of Paleobiology of the Polish Academy of Sciences. The reptile had relatives in Poland.
Wolf culling does more harm than good; all scientific studies confirm this, says Sabina Pierużek-Nowak, PhD, a professor at the University of Warsaw. For example, when a parental pair is killed, the young individuals, left without care, start hunting farm animals.
Mussels are extraordinary organisms that have dominated aquatic ecosystems for millions of years - from the depths of the oceans to the sources of streams. They are long-lived, with some species living for hundreds of years. Despite this, their numbers have been decreasing drastically in recent decades. New research by Polish scientists - Tadeusz Zając, PhD, and Katarzyna Zając, PhD, professors at the Institute of Nature Conservation of the Polish Academy of Sciences - sheds light on the causes of this phenomenon.
The coevolutionary interactions between avian brood parasites and their hosts can lead to selection for refined defences in the host to avoid parasitism and increased specialisation of the parasite to specific hosts. A new study by researchers from the Museum and Institute of Zoology, PAS, show how these interactions can lead to diversification in the phenotypes of hosts and parasites and contribute to the formation of new species.
Long-term research is of great importance for natural sciences. Unfortunately, it is reluctantly financed because it does not fit into the model of science focused on quickly achieved and published results, says Grzegorz Neubauer, PhD.
Porpoises are incredibly difficult to observe - they are small and very shy animals. In the Baltic Sea, and especially in Polish waters, the porpoise is a guest and therefore strictly protected. However, this species is not endangered globally, says oceanologist Professor Jan Marcin Węsławski.
From several days to even hundreds and thousands of years - this is how long it takes for water precipitation that fell on the Earth's surface to reach the groundwater level, where over 70 percent of drinking water in Poland comes from, says hydrogeologist Małgorzata Woźnicka, PhD.
The mating habits of birds can be spectacular. Some species use singing, others dance and do aerial acrobatics, others still show their strength. There are also females who choose a male based on the appearance of the nesting site he occupies, says ornithologist Grzegorz Neubauer, PhD, a professor at the Museum and Institute of Zoology of the Polish Academy of Sciences.
There is hope that microalgae inhabiting peatlands will absorb more and more carbon dioxide as the temperature increases. They may not stop climate change, but they will be our allies in the fight against global warming. So far, research has ignored the role of this group of organisms in climate analyses.
The foraging activity of fish and large aquatic invertebrates, such as crayfish, contributes to the mechanical fragmentation of microplastics, reducing their average size and accelerating their degradation, scientists from the University of Warsaw, Warsaw University of Life Sciences, AGH UST, the University of Rzeszów and an Indian university have demonstrated.
