Leaf beetles Chrysomelidae of Rovno amber, from the Late Eocene, are recorded and described. Chrysomelidae of Rovno amber are represented by three subfamilies： Galerucinae （Alticini）, Chrysomelinae, and Enmolpinae. Two new genera and three new species of Alticini： Manobiomorpha Nadein, gen. nov. （type species Manobiomorpha eocenica Nadein, sp. nov.）, Psyllototus Nadein, gen. nov. （type species PsyUototus progenitor Nadein, sp. nov.）, and Crepidodera decolorata Nadein et Perkovsky, sp. nov. are described. A new chrysomeline genus and species Paleophaedon minutus Nadein gen. nov. et sp. nov. is described. Probable trophic association of Crepidodera decolorata sp. nov., the taxonomic positions of Manobiomorpha gen. nov. and PsyUototus gen. nov., and the composition of leaf beetle faunas of Middle and Late Eocene of Europe are discussed.

Parasitoids have long proven to be model organisms in studying resourcerelated constraints on immature development. Here we examine the relationship between host cocoon （= pupal） size in the gregarious endoparasitoid wasp, Cotesia glomerata, and development time and adult size in the solitary idiobiont hyperparasitoid, Pteromalus semotus. Little is known about the biology or ecology of this ecto-hyperparasitoid species, although it is one of the major secondary hyperparasitoids of C. glomerata. The size of the adult wasp covaried with the size of the host cocoon at parasitism. Moreover, female wasps were larger than male wasps for a given cocoon size. Adult wasps have remarkably long life-spans, 3 months on average. Longevity did not significantly differ with sex. We also examined how larvae of P. semotus exclude other potential competitors. P. semotus is protandrous, with females taking significantly longer to complete their development than males. In experiments where several eggs of P. semotus were placed on individual pupae of C. glomerata, newly hatched hyperparasitoid larvae moved rapidly over the surface of the host and destroyed the eggs of any conspecifics by biting them before they would initiate feeding on host tissues. Our results are discussed in relation to those with other studies with solitary ichneumonid idiobiont hyperparasitoids of C. glomerata.

We review 20 year long investigations by the schmalhausen institute of zoology on radioecological and ecological consequences of the Chernobyl catastrophe for wild animals in the Exclusion Zone （EZ） around the nuclear plant. Using previous observations on bird migrations through Ukraine, we assessed the 137^Cs and 90^Sr carry-out with migrants from the EZ. In addition, we selected animal species as standard indicators of the state of the environment to map ： 1 ） contamination of vertebrates with 137^Cs in the EZ and 2） beta-activity of mollusc shells indicating 90^Sr, in the whole Dnieper drainage area, in the Kiev Administrative Region, and in the EZ. We revealed regular seasonal and long-term trends, relative radionuclide accumulation by different species, transfer and accumulation factors, and used these measurements to diminish the enormous variation and complexity of the data. Secondary ecological changes in forest, devastated by direct irradiation, were caused by the crash of trophic chains and an outbreak of insect pests on dead or sick trees. Ninety-nine percent of the EZ area was not affected directly by irradiation. Ecological changes in this area have been caused by evacuation of the public, cessation of agriculture and forest management, and decontamination on a large scale. After initial changes, animal density and distribution have been stabilized at a limit restricted by natural resources, predators and poachers. A herd of Przewalski horses was successfully introduced into the EZ years ago. We renewed the protected state of nature reserved sites, which existed before, and proposed to expand the area of nature reservation.

The impact of starvation and anhydrobiosis on the number and size of the storage cells in the tardigrade species Milnesium tardigradum, Paramacrobiotus tonollii and Macrobiotus sapiens was investigated to gain more insight on the energetic side of anhydrobiosis. Storage cells are free floating cells within the body cavity of tardigrades and are presumed to store and release energy in form of glycogen, protein and fat to maintain a constant nutrient regime for the other tissues. The body size of the animals was not correlated with the size of the storage cells, however, M. tardigradum the largest species analysed also had the largest storage cells. A reduction in the size of the storage cells is apparent in all three species after seven days of starvation. A seven-day period of anhydrobiosis leads to a decrease in cell size in M. tardigradum but not in P. tonollii and M. sapiens. Although M. sapiens was raised on green algae, and M. tardigradum and P. tonollii were fed with rotifers and nematodes this difference in nourishment was not reflected in the response of the storage cells to anhydrobiosis

At the beginning of 2016, I returned to the Baima Snow Mountain with a CC＇I-V film crew. As the birth place of the Yunnan snub-nosed monkey, Baima Snow Mountain in northwest Yunnan belongs to the transition zone between the Qinghai-Tibet and Yunnan-Guizhou plateaus, and is regarded as the most magnificent of the Yunling Mountains. Revisiting my old haunt, I cannot help but recall the international snub-nosed monkey research launched by the Kunming institute of zoology （KIZ） so many years ago.
