Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

open access: yesJSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

open access: yesThe Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...
