Does Risk Aversion Make A Case For Conservatism, Ralph M. Perhac Jr. Sep 1996

Does Risk Aversion Make A Case For Conservatism, Ralph M. Perhac Jr.

RISK: Health, Safety & Environment (1990-2002)

Dr. Perhac argues that risk aversion, alone, and assuming it is justifiable, does not support the prefer ability of overstating, as opposed to understating, mean risk.


Comparing Risks Thoughtfully, Adam M. Finkel Sep 1996

Comparing Risks Thoughtfully, Adam M. Finkel

RISK: Health, Safety & Environment (1990-2002)

Dr. Finkel argues that comparing risks is neither impossible nor immoral - but is nonetheless very difficult. He then discusses two major pitfalls of making such comparisons, one commonly cited and one routinely ignored, before sketching a framework for improving them.

A Potential Understory Flora For Oak Savanna In Iowa, Karl T. Delong, Craig Hooper Jan 1996

A Potential Understory Flora For Oak Savanna In Iowa, Karl T. Delong, Craig Hooper

Journal of the Iowa Academy of Science: JIAS

Oak savanna occurred in Iowa until the time of settlement and then was degraded rapidly. There were no scientific studies of savanna prior to, or after, settlement, and now no high-quality examples exist within the state. To identify those vascular plants adapted to live in the understory of savanna we examined regional and local flora for species that occurred in both prairie and broken woodland, and for species that occurred m both openings and forest. We then compiled a detailed description of the ecological range of habitats for each of these species. We identified 252 species (39 graminoids, 183 forbs, …

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther Jan 1996

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther

Journal of the Iowa Academy of Science: JIAS

Aconitum noveboracense Gray (Ranunculaceae), commonly known as northern monkshood, is a federally threatened herbaceous perennial that occurs in disjunct populations in Iowa, Wisconsin, Ohio and New York. It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes. Field studies reveal that A. noveboracense has a complex life history. Perennation of individual plants occurs through the annual production of daughter tubers. Vegetative reproduction is commonly observed, and can occur by means of aerial and subterranean bulbils, as well as by development of adventitious root buds. Populations also reproduce sexually …


Geochemistry Of Buried Midcontinent Rift Volcanic Rocks In Iowa: Data From Well Samples, Karl E. Seifert, Raymond R. Anderson Jan 1996

Geochemistry Of Buried Midcontinent Rift Volcanic Rocks In Iowa: Data From Well Samples, Karl E. Seifert, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

We analyzed welt cores and cuttings from deep wells into Precambrian igneous rocks from five separate pacts of the buried Midcontinent Rife System in Iowa for major and trace elements. A total of 21 samples, 9 cores and 12 cuttings, were analyzed for trace elements by instrumental neutron activation analysis (INAA) and 11 of these, 9 cores and 2 cuttings, were analyzed for major elements by inductively coupled plasma (ICP) analysis.


Pathogenicity Of Septoria Aquilina Isolated From Black Hills Bracken, A. Gabel, C. Salazar Jan 1996

Pathogenicity Of Septoria Aquilina Isolated From Black Hills Bracken, A. Gabel, C. Salazar

Journal of the Iowa Academy of Science: JIAS

Septoria aquilina, a pathogenic fungus isolated from Pteridium aquilinum growing in the Black Hills was studied from 1991-1995. S. aquilina sprayed at 8,000 conidia/ml on transplanted fronds followed by high humidity caused severe necrosis seven days after inoculation and disease severity increased until fronds died. Severe necrosis also developed from inoculations at 4,000 and 2,000 conidia/ml. Less severe symptoms developed from inoculations at 1,000 conidia/ml. Inoculations at 4,000 conidia/ml not followed by high humidity caused less necrosis than inoculations at the same concentration with high humidity. Inoculations at 4,000, 2,000, and 1,000 conidia/ml on fronds grown from spores caused similar …

Abandon The Paddock : A Valid Method Of Rehabilitation?, Max Abensperg-Traun Jan 1996

Abandon The Paddock : A Valid Method Of Rehabilitation?, Max Abensperg-Traun

Journal of the Department of Agriculture, Western Australia, Series 4

The scale of the revegetayion needed to combat land and habitat degradation can only be achieved over a long period of time. An alternative to revegitation is to abandon parts oof the farm for passive regeneration. Max Abensperg-Traun, and his colleagues from CSIRO Division of Wildlife and Ecology, report on some outomes from such a strategy.


No-Till Sowing : Helping To Keep Cropland Soils In Place, Kevin Bligh, Paul Findlater Jan 1996

No-Till Sowing : Helping To Keep Cropland Soils In Place, Kevin Bligh, Paul Findlater

Journal of the Department of Agriculture, Western Australia, Series 4

Repeated erosion of tilled land can ;ower crop and pasture yields because of reduced available moisture and nutrient storage. Kevin Bligh and Paul Findlater look at the causes of water and wind erosion and the role of no-till sowing in minimising erosion.


An Annotated Checklist Of The Spiders Of Northwestern Iowa And The Loess Hills Of Western Iowa, Barbara J. Abraham Jan 1996

An Annotated Checklist Of The Spiders Of Northwestern Iowa And The Loess Hills Of Western Iowa, Barbara J. Abraham

Journal of the Iowa Academy of Science: JIAS

Spiders were collected by the author from various habitats in 16 counties of northwestern Iowa and the loess hills of western Iowa during the summers of 1985 and 1990-1992. Additional donated specimens from the same region in 1981and1989 were identified by the author. Twenty-three families, 92 genera and 184 species have been identified.


Improving Dairy Farm Performance, Ruth Dilley Jan 1996

Improving Dairy Farm Performance, Ruth Dilley

Journal of the Department of Agriculture, Western Australia, Series 4

Western Austraian sairy farmers produce more milk per cow and per farm than their eastern Sttates counterparts and the milk is also of higher quality. But there is always room for improvement and as grain prices rise it is crucial that maximum benefit is derived from the cheapest feed source - the pasture.With this in mind Ruth Dilley looks at the Dairy Farm Performance Program - a comprihensive farm database developed by Agriculture Western Australia.


Something Fishy Is Going On - Aquaculture, David Berry Jan 1996

Something Fishy Is Going On - Aquaculture, David Berry

Journal of the Department of Agriculture, Western Australia, Series 4

Aquaculture id Australia's fastest growing primary industry. Product from fish farms is currently valued at $399 million, forecast to exceed $5oo million by 2000.

Whilst the figure pales into insignificance alongside world production (about $45 billion) it does represent a huge window of opportunity for prospective investors and for Australian primary producers who are keen to diversify.

David Berry reports on the prospects for yabbie and marron farming in Western Australia.
