#アメリカザリガニ 【長野県実家周辺】8月中旬
久しぶりに見ました。散歩中、意識して探しながら歩いてみたけど、この１匹しか見てません。こちらは、日本の侵略的外来種ワースト100に指定されている生き物なので、日本の山野で見かけなくなるのは、良いことですね。私が子どもの頃は、スルメを糸の先に結び付けて、ザリガニ釣りとかしてましたね。今の子どもたちは知らないと思います。

Congrats to @AdamLovasKiss whose #PhD paper on how #procambarus #Crayfish invasion facilitates #dispersal of plants and invertebrates by #gulls is now highly cited @ajgreen_lab @ebdonana @PhD_EBD #EBDpub
Gastroliths from alien #crayfish useful for #paleolimnology or #diet studies. We have seen them in #cormorants feeding on #Procambarus @freshwaterblog @freshwaterbio @AdamLovasKiss @SteveThackeray @UoM_EES @CEHLakeEcoGrp @MedWetOrg

Crayfish becomes internet hero by detaching claw to escape boiling soup. Looks like #procambarus @OficialdeguiF
