Drought is an important yield-reducing factor for corn and soya bean which are the two major crops in the Delaware, Maryland and Virginia (Delmarva) region of the United States. Cowpea (Vigna unguiculata L. Walp.) is primarily grown in drier regions of the world where it is one of the most drought-resistant food legumes. Field experiments were conducted in which 10 genetically diverse cowpea ge...

Partial life histories of 24 Hesperiinae incertae sedis that feed on Dicotyledons are described and illustrated. The genera dealt with are: Acada, Acleros, Andronymus, Fresna, Gorgyra, Melphinyet, Meza, Paronymus, Parosmodes, Platylesches, and Teniorhinus. The food plants of Gorgyra (mainly Connaraceae), Melphinyet (Euphorbiaceae) and Platylesches (Chrysobalanaceae) stand out as clearly distinc...

Terrestrial isopods are known to be sensitive to humidity, brightness or temperature. Until now, aggregation was assumed to depend on these sensitivities as a result of individual preferences. In this paper, we show that the social component is also important in the isopod aggregation phenomenon. In experimental arenas with two identical shelters up to nearly 90% of woodlice aggregated under sh...

On March 11, 2011, a 9.0-magnitude earthquake struck east Japan, following tsunami. Many people are forced to live in evacuation shelters without enough life-saving drugs. Asthma control for management of health crisis is required, because asthma exacerbation is a major cause of morbidity, can need acute care and results in death. However, it remains obscure what parameter should be used in pri...

Current climate change models predict significant changes in rainfall patterns across Europe. To explore the effect of drought on soil CO2 efflux (FSoil) and on the contribution of litter to FSoil we used rain shelters to simulate a summer drought (May to July 2007) in an intensively managed grassland in Switzerland by reducing annual precipitation by around 30% similar to the hot and dry year ...

Studies of the desiccation tolerance of the seedlings of five tropical trees were made on potted plants growing in a greenhouse. Pots were watered to field capacity and then dehydrated for 3 to 9 weeks to reach various visual wilting stages, from slightly wilted to dead. Saturated root hydraulic conductance was measured with a high-pressure flowmeter, and whole-stem hydraulic conductance was me...

during a survey on pistachio, pistacia vera l., pests in isfahan, iran, in 2015, some lepidopteran larvae living and feeding inside galls of the wrinkling pistachio aphid, forda hirsuta mordv., were observed. after laboratory rearing of these larvae, the moths were identified as altenia mersinella (staudinger, 1879) (lep.: gelechiidae) by the third author. this species has previously been repor...

Since the 1940s, perceived companion animal overpopulation in the United States has been an important issue to the animal welfare community (Moulton, Wright, & Rinky, 1991). This surplus of animals has resulted in millions of dogs and cats being euthanized annually in animal shelters across the country. The nature and scope of this problem have been notoriously difficult to characterize. The nu...

Shelters for protection against the effects of nuclear weapons are often stated to be useless, largely because of firestorms. Recent models purport to show that nuclear weapons are more likely to cause firestorms than previously thought. These controversial models are based on uncertain assumptions, which are difficult or impossible to test. Regardless of the predictive validity of fire models,...
