Резюме. Чужеродный вид наземных слизней Deroceras reticulatum (Müller, 1774) впервые отмечен на Шантарских островах. Это второе местонахождение данного вида на Дальнем Востоке России. Ранее сетчатый слизень был известен лишь на побережье Тауйской губы Охотского моря. Приводятся сведения по общему распространению данного вида и о возможных путях его проникновения на Шантары. Summary. Alien terrestrial slug Deroceras reticulatum (Müller, 1774) is first recorded on the Shantar Islands. This is the second location of the species on the Russian Far East. Earlier gray field slug was known on coast of Taui Bay of Okhotsk Sea. Data on total distribution of the species and possible way of invasion are presented.
In the foothill rivers of the south of Primorsky Krai (Russian Federation), during the abnormally hot summer-autumn season of 2021, the number of net-spinning larvae of the caddisflies Stenopsyche marmorata Navas, 1920 (Stenopsychidae) sharply increased. Here we describe the phenomenon of widespread use by these caddisfly larvae of the shells of live bivalves Middendorffinaia Moskvicheva et Starobogatov, 1973 (Unionidae) to attach their feeding nets. As a result, the immobilized river mussels could not move to the deeper sites for wintering, and in the coming winter season they died due to freezing into ice. The described phenomenon illustrates the indirect negative impact of climate change on vulnerable species of river biota.

Aleksey Nikolaevich devoted his whole life to conservation of the unique nature of Primorsky Krai. All of us, members of the journal’s editorial board, will remember him with gratitude and continue his life’s work.
