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.

The global whaling industry experienced a boom c. 1840-1950 as technology allowed whalers to hunt the Southern Ocean around Antarctica.

Under standard models, we would have expected krill populations to have *exploded*.

Instead, they DROPPED exponentially.

Let's talk about the KRILL PARADOX.

Change in distribution and abundance of southern right whales. (A) Shows historical and contemporary wintering distributions (Figure 1 from Carroll et al., 2018), and (B) shows decline in abundance and subsequent recovery (solid line is the mean, dashed line shows upper and lower 95% CI). Modified Figure 1 from Jackson et al. (2008). Contemporary sightings are divided into regions where large aggregations are seen during winter: Argentina (ARG), Brazil (BZL), South Africa (SAF), southwest Australia (SWA), south central Australia (SCA), and New Zealand sub-Antarctic (NZSA) and regions where sightings are typically of small numbers of individuals per year. The large aggregations are IWC management units and correspond to historical whaling grounds, although another 5 whaling grounds show little sign of recovery. Summer feeding areas are poorly described and so not shown.

This whiptail gulper eel (Saccopharynx lavenbergi) was spotted 880 meters deep in Monterey Canyon back in 1993—one of only 18 sightings in nearly 40 years! 📹️😍 With its massive mouth and glowing tail, this deep-sea icon even inspired MBARI’s logo. Watch here: www.youtube.com/watch?v=3nwD...

How did animals repeatedly conquer land? 🌊➡️⛰️ We analysed ~1,000 gene repertoires (24M genes!) from all animal phyla to uncover how this happened. Work led by @gemmaeling.bsky.social & Klara Eleftheriadi, both first coauthors of this titanic effort!

Diverging fish biodiversity trends in cold and warm rivers and streams - Nature

In the past three decades, fish abundance, richness and uniqueness have diverged across cold and warm streams, and the effects on native fish communities of stream warming and increases in introduced fishes have magnified each other.
