Ardilla Gris Oriental

ヒガシハイリス（Sciurus carolinensis）は北米東部原産の中型樹上性げっ歯類で、ヨーロッパをはじめ世界各地に移入された外来種である。IUCNレッドリストでは軽度懸念（LC）に分類されており、都市公園や郊外の森林環境への適応力が高く、堅果の埋蔵行動が植物の種子散布に重要な役割を果たしている。英国ではニホンリスを食物競争で駆逐しており、侵略的外来種としても問題視されている。

Common thrip

<em>Thrips trehernei</em> is a species of thrips in the order Thysanoptera, family Thripidae, recorded from Denmark, Norway, Sweden, and the United States. It is Not Evaluated on the IUCN Red List. Relatively little is known about the ecology and biology of this species compared to economically significant thrips. Like other thysanopterans, it is likely a plant feeder, inhabiting flowers, foliage, or bark surfaces of host plants in temperate regions where it occurs. The genus <em>Thrips</em> is large and diverse, with many species associated with specific plant hosts or habitats. This species has been recorded from Scandinavian and North American localities, suggesting a trans-Atlantic distribution, possibly facilitated through plant trade or natural dispersal. Adult thrips are minute insects typically measuring 1–2 millimeters in length, with characteristically fringed wings. Biological traits such as precise host plant associations, body weight, lifespan, reproductive output, and generation time remain poorly documented in standardized scientific assessments for <em>Thrips trehernei</em> specifically.
