Effects of forest treatments on nutritional carrying capacity for white‐tailed deer in mid‐rotation loblolly pine stands

Wildlife Society Bulletin, EarlyView.
In this study we compared nutritional carrying capacity (NCC) for white‐tailed deer (Odocoileus virginianus) among 6 treatment combinations in mid‐rotation loblolly pine (Pinus taeda) forests, including 3 levels of commercial thinning. We also paired each level of thinning with prescribed fire, prescribed fire with herbicide, or herbicide only ...

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global change and associated disturbances are increasing the risk of regeneration failure for tree species in temperate forests. Seedlings are particularly vulnerable to water stress due to their shallow root systems, making below‐ground plasticity a potentially key ...

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

Animal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Comparison of Support Vector Machine and Random Forest Algorithms for Invasive and Expansive Species Classification Using Airborne Hyperspectral Data

Remote Sensing, 2020
Invasive and expansive plant species are considered a threat to natural biodiversity because of their high adaptability and low habitat requirements. Species investigated in this research, including Solidago spp., Calamagrostis epigejos, and Rubus spp ...

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Micropropagation of Rubus spp.

Agricultural and Food Science, 1986
Rapid micropropagation of ‘Black Satin’, ‘Thornless Evergreen’ and ‘Bedford Giant’ was achieved by culturing shoot tips in a 1/1 MS. The best medium in the introduction stage contained 2.0 mg/l BAP. Shoot proliferation occurred with 3.0 mg/1BAP.
