Now available in Systematic Biology, a new paper (and R package) in which we outline an approach to account for non-independence in comparative analyses of lineage-pair traits academic.oup.com/sysbio/advan...

The Comparative Analysis of Lineage-Pair Traits

Abstract. For many questions in ecology and evolution, the most relevant data to consider are attributes of lineage pairs. Comparative tests for causal rel

TL/DR: Anyone interested in comparing evolution across fishes should consider deep-benthic and deep-pelagic environments as distinct entities

What's similar: greater emphasis on elongate body shapes vis-a-vis shallow marine settings

What's different: mechanisms of accruing body shape diversity, from evolutionary rates to colonization pathways

Here we use the FishShapes dataset to uncover similarities and differences in body shape diversification across deep-sea fishes from pelagic and benthic habitats

Deep-sea habitats are diverse and invoke different selection pressures on organisms. This is well known by marine ecologists, but comparative evolutionary biologists are catching up.

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...
