Article Synopsis
- Habitat partitioning among similar species helps them coexist by reducing competition.
- Experimental tests on two types of burying beetles (Nicrophorus) revealed that the forest species N. orbicollis consistently outcompeted the wetland species N. hebes for carcasses, which are vital for reproduction.
- When both species were present, N. hebes struggled to reproduce in the forest due to the dominance of N. orbicollis, but thrived in wetlands where it could handle breeding challenges better.
- The study highlights that while competitive abilities may work in favorable conditions (like forests), they can be detrimental in harsher environments (like wetlands), demonstrating the balance of exclusion and tolerance in habitat use.
Histone H3 Lys-4 methylation is predominantly catalyzed by a family of methyltransferases whose enzymatic activity depends on their interaction with a three-subunit complex composed of WDR5, RbBP5, and Ash2L. Here, we report that a segment of 50 residues of RbBP5 bridges the Ash2L C-terminal domain to WDR5. The crystal structure of WDR5 in ternary complex with RbBP5 and MLL1 reveals that both proteins binds peptide-binding clefts located on opposite sides of WDR5's β-propeller domain.
