Beetle Pollination in the Holoparasitic Lophophytum pyramidale (Balanophoraceae): A New Case of Brood‐Pollination Mutualism?

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1542-1554, December 2025.
ABSTRACT Beetle pollination is considered an ancestral trait in angiosperms, retained in a few specialised families engaging in longstanding interactions with ancient groups of beetles. While beetles represent some of the earliest angiosperm pollinators, there is also increasing evidence that some beetle‐pollinated plants represent a derived condition.

Ups and Downs among Danish Urban Harvestmen

open access: yesArachnology, 2018
The opilionid fauna of Northern Europe, including Denmark, has become enriched by range expansion of several species originating from southern Europe, and this process is expected to continue into the future. I present data that describe the changing occurrence (relative abundance, locality representation) of invasive as well as native harvestman ...

Respiratory energetics of two Florida harvestmen

open access: yesComparative Biochemistry and Physiology Part A: Physiology, 1993
Abstract 1. 1. Standard rates of metabolism were measured in two Florida harvestmen, Leiobunum aurugineum and Vonones ornata. 2. 2. Rates of metabolism of Leiobunum aurugineum were ca 40% higher than those of V. ornata when adjusted to a common body size. This difference was attributed to differences in their respective life histories. 3.

Riparian Vegetation and Arthropod Responses to Dam Removal and Habitat Restoration Along the Kalamazoo River, Michigan, USA

open access: yesRiver Research and Applications, Volume 41, Issue 9, Page 2017-2031, November 2025.
ABSTRACT Riparian ecosystems harbor diverse biota and provide numerous services to rivers including mitigating sediment run‐off, regulating temperature, and contributing food‐web subsidies. Dams are a major threat to riparian communities, but dam removal and riparian restoration efforts have the potential to restore these communities and the services ...

Amid the fallen leaves: Intense collecting in the Northern Atlantic Forest reveals new minute harvestmen species (Opiliones: Stygnidae) within the Area of Endemism of Pernambuco

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Stygnids represent one of the most diverse harvestman families, with many endemic species in the Area of Endemism of Pernambuco, a pattern increasingly evident by intensified sampling in the region over the years. The area is also recognised for hosting a group of understudied minute leaf‐litter dwellers stygnids, represented by the following ...

Vegetation Structure and Soil Composition Influence Opiliones Diversity Across Spatial Scales in Amazonia

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
We examined how vegetation structure and soil composition influence the diversity and distribution of Opiliones across spatial scales in Central Amazonia. At the local scale, trees provided the richest microhabitats, strongly shaping species richness and composition, while at the regional scale, soil sand content was the main driver of species turnover.
