クロサギが多いです。こちらで成魚を見ることは少ないのですけど。

うちの実験所でも院生向けのオープンな桁網調査ができないかなーと考え中。150mくらいまでとか?需要があるのかわからんけど。

Our Special issue on Visual Ecology in Challenging Environments is out: #coral reef & #deep-sea fishes, #reindeers on polar daylight, #bioluminescence, non-visual #pigments & life in dark caves. Happy to co-edit with Sara Stieb + thks to all contributors! See in Functional Ecology: buff.ly/z5AYxZQ

崩壊指数とか最近出したことなかったので調べるのに丸一日かかってしまった。

昨日、宮津でオオクチイケカツオが定置に入ったらしく。ぽつぽつ獲れますね。

When you visit Friday Harbor Labs, @fishguy.bsky.social always has cool fish to discuss 🐟 Last week we pondered the horned searobin (Bellator militaris), & what its spines could be for. CT scan available on MorphoSource for you to explore

うちの標本は長らくホルマリンに浸かってたのでダメでしょうね…。

Attempted eradication of smallmouth bass promotes rapid evolution. Here's the study that is the focus of the Scientific American article: www.pnas.org/doi/10.1073/...

So excited to see our paper on #phylogenetics and #morphometrics integrated with feeding #ecology in the surgeonfishes by @linnealungstrom.bsky.social get posted, her first in a series on their incredibly cool biology. 🐟🦑🧪🌎🌿

No better reason to join Bluesky then to say the first chapter of my PhD is out as a preprint! New surgeonfish phylogeny, ecomorphological relationships, evolutionary shape correlations-with NEW method to accurately account for phylogenetic covariation among shapes!

Phylogenetic relationships and the evolution of fin and body shape in the surgeonfishes
Patterns of evolutionary change in the fin and body shapes of fishes are strongly related to dietary ecology and locomotor mechanisms, and associations between shapes affects ecomorphological relation...

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.

今日はクラゲ先生てスナモグ先生も一緒に市場。キチヌが普通に獲れるようになってきた。

10年ぶりの実験所でした。変わってしまったところには驚くばかりでしたが、すばらしい機会を作っていただいたスタッフのみなさんに感謝。

The weedy #rhinopias (Rhinopias frondosa) is a holy grail species for any fish nerd, and I returned to shoot this guy several days in a row.

アメリカの院生から現役の研究者を紹介してほしいと言われたんですけど、ぱっと思い出せなくて。

シワイカナゴとかクダヤガラの研究者って日本では誰だろう…?

近大の亀先生の耳石チームが来所中。解析システムに不具合があったようで申し訳ない…。
