Lay Summary: Competition often occurs among diverse parasites within a single host, but control efforts could change its strength. We examined how the interplay between competition and control could shape the evolution of parasite traits like drug resistance and disease severity.

Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant population differentiation and lineage diversification resulting in speciation, helping bridge the gap between macro- and microevolution through chromosomal evolution. We focus on angiosperms, a group that comprises the majority of extant plant species diversity and exhibits the largest chromosomal and genomic variations.

Caesarean birth has multiple, interrelated, and often mutually reinforcing bio-social etiologies. Evolutionary consequences of caesarean are uncertain. The goal of this study is to determine if caesarean births are more likely within family lineages by connecting and comparing lifetime birth experience (caesarean, vaginal) of individual women and generations of their families.

Recent evidence suggests that parasite-mediated reductions in food intake (i.e., anorexia) in herbivores can trigger trophic cascades that increase producer biomass.

Wiedemann-Rautenstrauch syndrome (WRS) is a rare neonatal progeroid disorder primarily associated with pathogenic variants in POLR3A. However, the pathogenicity of certain variants remains unclear. Here, we report a WRS case carrying the POLR3A c.

For many questions in ecology and evolution, the most relevant data to consider are attributes of lineage pairs. Comparative tests for causal relationships among traits like 'diet niche overlap', 'divergence time', and 'strength of reproductive isolation (RI)' - measured for pairwise combinations of related species or populations - have led to several groundbreaking insights, but the correct statistical approach for these analyses has never been clear. Lineage-pair traits are non-independent, but unlike the expected covariance among species' traits, which is captured by a phylogenetic covariance matrix arising from a given model, the expected covariance among lineage-pair traits has not been explicitly formulated.
