Bergmann's rule (Ecogeographic rules 🌍)

Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions. The rule derives from the relationship between size in linear dimensions meaning tha...

Larger-bodied organisms predominate in colder areas ("#BergmannsRule"). @wwAAAddddEEE @AdamSiepielski & @sinkingdiatom show that in #diatoms, #genome size, rather than cell size, is a strong predictor of species abundance in the polar oceans #PLOSBiology https://plos.io/4cm5WeK

Diatom abundance in the polar oceans is predicted by genome size

Body size is a fundamental predictor of organismal abundance, and larger-bodied organisms predominate in colder areas ("Bergmann’s rule"). This study of diatoms reveals that in these unicellular organisms, genome size, rather than cell size, is a strong predictor of species abundance in the polar oceans.

#Dinosaurs buck #BergmannsRule, a more than 170-year-old biological principle suggesting that species from colder environments are generally larger than close relatives from warmer climates. #biology https://cosmosmagazine.com/history/palaeontology/dinosaurs-break-bergmann-rule/?utm_source=Live+Audience&utm_campaign=e5a8c8bad3-briefing-dy-20240415&utm_medium=email&utm_term=0_b27a691814-e5a8c8bad3-50179668

Dinosaurs break 200-year-old Bergmann's rule of zoology

A new analysis of the fossil record shows that dinosaurs bucked an ecological trend known as Bergmann’s rule.

"The 1800s-era principle is stating that #animals in high-latitude, cooler climates tend to be larger... New study shows: #BergmannsRule is only applicable to a subset of homeothermic animals (that maintain stable body temperatures), and only when you consider temperature, ignoring all other climatic variables"
