Germination of Western Soapberry as Affected by Scarification and Stratification

open access: yesHortScience, 1984
Abstract Western soapberry (Sapindus drummondii Hook & Arn.) seeds were collected in Sept. 1982 and scarified with acid or hot water, or treated by freezing. The seeds were sown immediately or after cold-moist stratification for 90 days.

Coexistence of coinvading species with mutualism and competition

open access: yesEcology, Volume 106, Issue 2, February 2025.
Abstract All interactions between multiple species invading together (coinvasion) must be accounted for to predict species coexistence patterns across space. Mutualisms, particularly, are known to influence species' population dynamics and their invasive ability (e.g., mycorrhizal fungi with partner plants).

Climate and land‐use change impacts on cultural use berries: Considerations for mitigative stewardship

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 791-802, July 2024.
Cultural use berries are prized foods and medicines across the United States and Canada, with almost 200 different species used by Indigenous Peoples. Berries are increasingly being impacted by environmental and land‐use change. Berry habitats, how and when berry plants reproduce, and the volume of berries available for harvest each year are shifting ...

Impacts of Mineral Dust on Trace Element Concentrations (As, Cd, Cu, Ni and Pb) in Lichens and Soils at Lhù’ààn Mân’ (Yukon Territory, Canada)

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 6, June 2024.
Abstract Dust is a mineral aerosol of the atmosphere that often contains trace elements such as As, Cd, and Pb. Lhù’ààn Mân’ (Kluane Lake), located in southwestern Yukon, is a region of frequent dust activity. In 2016, the lake level fell due to a dramatic decrease in inflow from glacier meltwater, and the delta of the lake became an important source ...

Somatic embryogenesis in leaf tissue culture of Soapberry (Sapindus mukorossi Gaertn.)

open access: yesPlant Biotechnology, 2012
Leaf explants formed embryogenic calluses at a frequency of 53.9% when cultured on B5 media supplemented with 0.1 mg l 1 2,4-dichlorophenoxyacetic acid (2,4- ) and 0.01 mg l 1 6-benzyladenine (BA) for 6 weeks. Upon transfer onto media with 5 mg l 1 abscisic acid, embryogenic calluses yielded somatic embryos at 73%.

Pest categorisation of Popillia quadriguttata

open access: yesEFSA Journal, Volume 22, Issue 6, June 2024.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Popillia quadriguttata (Coleoptera: Scarabaeidae), following a commodity risk assessment of bonsai Pinus parviflora grafted onto P. thunbergii from China, in which P. quadriguttata was identified as a pest of possible concern for the territory of the European Union.

Fire severity drives understory community dynamics and the recovery of culturally significant plants

open access: yesEcosphere, Volume 15, Issue 3, March 2024.
Abstract Anthropogenic influences are altering fire regimes worldwide, resulting in an increase in the size and severity of wildfires. Simultaneously, throughout western North America, there is increasing recognition of the important role of Indigenous fire stewardship in shaping historical fire regimes and fire‐adapted ecosystems.

Longer holding times decrease dispersal but increase mortality of translocated scaled quail

open access: yesThe Journal of Wildlife Management, Volume 88, Issue 1, January 2024.
We conducted a novel field experiment evaluating the effect of source population and delayed release strategy on the mortality and dispersal of translocated scaled quail. We found that a tradeoff exists between increased mortality and decreased dispersal distances as length of holding time increases.

Long‐term monitoring of cycles in Clethrionomys rutilus in the Yukon boreal forest

open access: yesIntegrative Zoology, Volume 19, Issue 1, Page 27-36, January 2024.
Fifty years of 3–4‐year cycles of the red‐backed vole in the Yukon boreal forest continue with increasing amplitude. Abstract Baseline studies of small rodent populations in undisturbed ecosystems are rare. We report here 50 years of monitoring and experimentation in Yukon of a dominant rodent species in the North American boreal forest, the red‐backed
