Differential Transmission

AbstractIn a novel modification of transient differential transmission spectroscopy, the first excited state S1 is reexcited via a second laser pulse towards a higher lying state Sn. The dynamics of the relaxation of this state Sn as well as the states created from Sn are revealed by a broad-band probe pulse.We find that the charge carrier generation efficiency from Sn is higher compared to S1. The push and probe durations below 20 fs enable the temporal resolution of the ultrafast relaxation of the Sn state and enables us to identify the two main contributions to enhanced charge generation from Sn, energy migration towards sites of high dissociation probability, and exciton dissociation during vibrational relaxation.

Рассмотрены результаты продолжавшихся несколько лет работ по детальному геоморфологическому картографированию участка заповедника «Курильский», остров Кунашир, Большая Курильская гряда. Слабо изученная и труднодоступная территория обследована с применением методов полевых геоморфологических исследований и полевых методов дешифрирования космических снимков. В результате этой работы собран обширный полевой материал о рельефе южной части острова Кунашир, который проанализирован и обобщён в форме серии крупномасштабных геоморфологических карт. Ранее на рассматриваемую территорию карты такого масштаба и такой тематики не создавались

The first data are presented about the Sciomyzidae of Iturup, the largest of the Kuril Islands. A total of ten species are recorded. Limnia setosa Yano is recorded for the first time from Russia; Tetanocera montana Day and T. phyllophora Melander are recorded for the first time from the Kuril Islands. Photographs, comments on diagnostic characters and adult habitats of poorly known species are given.

Abstract We describe the population of the Еndangered sea otter Enhydra lutris on Urup Island, one of the main wildlife refuges in the southern Kuril Islands of Russia. We reviewed historical and local reports of the sea otter, identified its habitat around the island, and surveyed the coastal waters of the island in 2019. Sea otters were numerous on Urup Island in the past but were hunted excessively and almost exterminated by the 1950s. Since then, sea otter populations have increased, and as the island is almost uninhabited we expected otters to be numerous. This was not the case, and we estimated the total population to be 363 ± SE 126 individuals. Our observation of two skinned carcasses on the shore suggests the low numbers are a result of poaching for the illegal fur trade. The case of Urup Island demonstrates that sea otters require active conservation, as even on a remote island they remain threatened. Establishment of protected areas would be an effective conservation measure for this species, although the suppression of demand for sea otter fur is of the greatest importance.
