We reveal that early stages of deadwood decomposition follow ecological rules of ephemeral resource patches. By tracking beetle communities over 12 years, we show how decomposition dynamics shape community assembly patterns, highlighting the importance of continuous deadwood input for sustaining saproxylic beetles in temperate forests.

Abstract Wood boring ambrosia beetles play a central role in the spread of Ceratocystis wilt of ‘ōhi‘a, a fungal disease caused by Ceratocystis lukuohia that kills the bioculturally important ‘ōhiʻa (Metrosideros polymorpha) tree. Beetles contribute to the spread of the disease by extruding fungus‐infected wood particles (frass). Disease mitigation can

ABSTRACT Aim It is not trivial to estimate the relative contributions of dispersal, vicariance, and range contraction in explaining the present‐day distribution of ancient clades. In this study, we aim to infer the historical biogeography of bark and ambrosia beetles using a genus‐level time‐calibrated molecular phylogeny that encompasses 70% of all ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

A taxonomic revision of Camptocerus Dejean (Coleoptera: Curculionidae: Scolytinae) [PDF]
The Neotropical ambrosia beetle genus Camptocerus Dejean was revised. Monophyly of the genus was tested using 66 morphological characters in a cladistic analysis. Camptocerus was recovered as monophyletic and 31 species were recognized.

Bottom–up and top–down diversification: asymmetric processes over space and time
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversification, and less on top–down processes through enemy‐associated differentiation.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The chemical components of exotic plants can change after invasion as they adapt to local conditions. Studying these changes is important because they can have a marked effect on ecosystem processes and dynamics.
