Comparing the Development and Viability of Horseshoe Crab Eggs Laid in Beach and Salt Marsh Habitats. [PDF]
Ecol EvolRecent research has found that horseshoe crabs spawn regularly in salt marshes. However, it remained unclear if eggs laid in salt marsh sediments are viable. In this study, we show that eggs laid in salt marsh habitats develop similarly to those laid in beach habitats, suggesting that salt marshes are viable spawning habitats for horseshoe crabs ...

Phylogeny and evolutionary modularity of a trilobite family over the Ordovician Radiation [PDF]
Estonian Journal of Earth Sciences, 2023 Trilobites are organized in packages; the adult trilobite body plan is composed of a cephalon (head), thorax (midsection), and pygidium (tail). These packages, or modules, are composed of traits that evolve semi-independently such that change in one ...
