Ectotrophic Mycorrhizae as Deterrents to Pathogenic Root Infections

Role of Mycorrhizae as Biofertilizer and Bioprotectant

Mycorrhizae are obligate fungi that predominate in the roots and soil of higher plants. They form association with plant roots in a host-non specific manner. Seven types of mycorrhizae have been known i.e. arbuscular, ecto, arbutoid, ectendo, ericoid, monotropoid and orchidaceous mycorrhizae. Out of these, arbuscular and ectomycorrhizae are the most abundant and wide spread. They promote plant ...

Evaluation of propane exploders as white-tailed deer deterrents

METHODS A representative sample of 974 currently homeless women surveyed in Los Angeles County in 1997 included 229 who were chronically homeless and at risk for unintended pregnancy. The relationships between perceived deterrents among these women a...

Mycorrhizae in Hawaiian Epiphytes!

In surveys in the Hawaiian Islands, mycorrhizae occurred frequently in epiphytic, nonorchidaceous angiosperms and pteridophytes. Both vesicular-arbuscular (VA) and ericoid mycorrhizae were present in epiphytes growing 1-3 m above the forest floor on dead and living tree trunks and on living tree ferns in montane wet forest sites. All eight angiosperm species were mycorrhizal, and 13 of 22 pteri...

Hard Marriage with Heavy Burdens: Labor Unions as Takeover Deterrents *

We examine the causal effect of unionization on a firm’s takeover exposure and merger gains. To establish causality, we use a regression discontinuity design that relies on “locally” exogenous variation generated by elections that pass or fail by a small margin of votes. Barely passing a union election leads to a significant reduction in a firm’s probability of receiving takeover bids. Conditio...
