Cospeciation is not the dominant driver of plant-pollinator codiversification in specialized pollination systems.

This study systematically rejects the long-standing notion of cospeciation as the dominant driver of codiversification between flowering plants and their specialist pollinators. Through cophylogenetic analysis of six classical specialized pollination systems, the research finds that cospeciation events are consistently outnumbered by non-cospeciation events, such as host-switch, duplication, and association losses. The findings support a more dynamic and diffuse codiversification paradigm, highlighting the importance of considering a broader range of evolutionary events in understanding plant-pollinator codiversification.

High outcrossing rates in a self-compatible and highly aggregated host-generalist mistletoe.

Plants have evolved various strategies to avoid inbreeding, but the mass flowering displayed by many plants predisposes them to within-plant pollen movements and self-pollination. Mistletoes often aggregate at multiple spatial scales. Their bird pollinators often visit several flowers of the same individual and of others on the same host tree.

Multigene Phylogeny Reveals gen. et sp. nov. and Familial Replacement of (Xylariales, Sordariomycetes, Ascomycota).

During our investigation of palm fungi in Thailand, two interesting taxa from and (Arecaceae) were collected. Based on phylogenetic analyses of a combined dataset of ITS, LSU, , and nucleotide sequences as well as unique morphological characteristics, we introduce the new genus within Xylariales, and a new species . Additionally, in our study, the genus is transferred to the family Cainiaceae based on its brown conidia and molecular phylogenetic evidence.

Scale-dependent contribution of host-specificity and environmental factors to wood-boring longhorn beetle community assemblage in SW China.

Longhorn beetles are extremely rich wood-boring insects possessing larvae that feed on the xylem of trees and/or lianas, which have detrimental effects on plants; in turn, the hosting plants may play a fundamental role in shaping the longhorn beetle community assemblage. However, factors determining the community assemblage of wood-boring longhorn beetles, particularly along the multiple spatial scales is still in need of further exploration. In this study, we designed an experiment across several spatial scales (from local to macro scales) from tropical to temperate climate gradients in Yunnan province, southwest China to examine to what extend the attributes of host-specificity is shaping the community assemblage along different spatial scales.

Plant apparency drives leaf herbivory in seedling communities across four subtropical forests.

Insect herbivory in natural forests is of critical importance in forest regeneration and dynamics. Some hypotheses that have been proposed to explain variation in leaf consumption by herbivores focus on biotic interactions, while others emphasize the role of the abiotic environment. Here, we evaluated the relative importance of both biotic and abiotic factors in explaining leaf damage on seedlings.
