W205-Controlling Winter Annual Broadleaf Weeds

, 2008
Maintaining a vigorous turfgrass stand will protect against weed infestation. However, during the winter months turfgrasses are not actively growing and are therefore susceptible to the encroachment of winter annual broadleaf weeds.

Increasing the Proportion of Broadleaf Species in Mixed Conifer-Broadleaf Forests Improves Understory Plant Composition and Promotes Soil Carbon Fixation

Understory vegetation is an important component of forest ecosystems, and the supply of nutrients in the soil is related to the growth and development of soil microorganisms and understory plants.

Afforestation mitigates soil nitrogen limitation by enhancing mineralization and lowering denitrification in central China

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation has profoundly altered soil nitrogen (N) transformation, particularly the key processes governing soil organic N and inorganic N dynamics which determine soil N availability.

Ectomycorrhizal community composition and extramatrical hyphal proportion predict soil carbon stocks at the landscape scale

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While fungal composition has been linked to soil carbon at global scales, these patterns are often difficult to disentangle from broad climatic gradients and species range limits. To address this constraint, we tested which aspects of ectomycorrhizal community structure

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Intermediate Anthropogenic Disturbances Boost Taxonomic and Phylogenetic Diversities but Reduce Functional Diversity in Subtropical Forests of Eastern China

Plants
Anthropogenic disturbances significantly impact plant biodiversity in subtropical forests. While prior research has primarily concentrated on taxonomic diversity, other dimensions of biodiversity, such as phylogenetic and functional diversities, remain ...

Imprelis 2SL Crabgrass and Broadleaf Weed Efficacy and Seedling Tolerance

, 2011
Previous studies have shown that Imprelis (aminocyclopyrachlor) 2SL has been successfully used in controlling broadleaf weeds in existing stands of turf. The objectives of this study were to evaluate various application rates and application sequences of

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...
