Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Egg‐Carrying and Cheliceral Comb in Ibaloniinae Harvestmen From the Solomon Islands (Opiliones: Podoctidae)

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Four new species of Ibaloniinae harvestmen are described from the Solomon Islands, Melanesia. Based on the original diagnosis of Euibalonius Roewer, 1915, and description of E. maculatus (Roewer, 1915), this material appeared related to that genus. However, examination of syntype photographs of the type species E.

Revision of the Elusive Harvestmen Genus Discocyrtulus Roewer, 1927 (Opiliones: Laniatores: Gonyleptidae): Investigating the Presumed Northeastern Brazilian Discocyrtus‐Like Relatives

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from ...
