The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

Cultivating biophilia: Domestic gardens foster positive emotions towards wildlife, with gardening influence shaped by species' ecological functions

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1218-1232, May 2026.
Abstract Understanding how different types of nature interactions influence emotional responses to animal species is especially important in the context of the biodiversity crisis, as these emotions can shape conservation‐related attitudes and behaviours. Gardening is recognised as one such interaction, although its influence likely depends on the type

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1535-1555, May 2026.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.

Use of a Cytobrush for Sampling the Ear Canal of Dogs With Otitis Externa

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 227-235, April 2026.
Cytological examination of the ear canal is essential for evaluating dogs with otitis externa (OE). The conventional sampling method uses a swab. However, the cytobrush (gynaecological cervical brush), already used for cytological collection from other anatomical sites, has not been adequately investigated for this purpose in dogs with OE.

Peri‐urban tree canopy assessments: Leveraging partnerships and technology for climate resilience

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 2, Summer / été 2026.
Abstract The urban tree canopy plays a crucial role in climate change mitigation and adaptation, yet peri‐urban environments—transition zones between urban and rural areas—remain unexplored in urban tree canopy assessments. With rapid urbanization expected to increase the global population to two‐thirds by 2050, managing peri‐urban green infrastructure
