On Kant's Definition of Analogy

open access: yesTheoria, EarlyView.
ABSTRACT In the Prolegomena, Kant offers his official definition of analogy in terms of the perfect similarity of the relations holding for completely dissimilar pairs. Although interpreters neglect to reconstruct Kant's views on similarity, they often cite the Prolegomena definition and take it to characterise analogy as the identity of two relations.

Tracking Invasive Pheretimoid Earthworm Species in New Brunswick, Canada: Impacts on Soil Properties and Other Invasive Earthworms

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 4, December 2026.
Jumping worms, a group of invasive earthworms, are spreading northward in North America, yet their impacts remain poorly understood, especially at their northern range limit. Following the initial detection of jumping worms in New Brunswick, we sampled 46 sites across the province to assess their regional spread and examine possible vectors of ...

Resurvey of Boreal Earthworm Communities in Southern and Northern Finland

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 4, December 2026.
Boreal forests account for 11.5% of the Earth's land area, and, unlike oceanic and mediterranean forests, their cold winters typically represent the harshest season for earthworms. In Fennoscandia, these forests are subject to substantial global changes, notably climate change and land use intensification, which might impact earthworm populations.
