Growth and nutrient partitioning of containerized Malus trilobata Schneid. and Acer syriacum Boiss. and Gaill. under two fertigation regimes
The native flora of Lebanon is threatened. As part of an ex situ conservation strategy, this study was conducted to determine if Malus trilobata (Schneid.) and Acer syriacum (Boiss. and Gaill.), two native Lebanese trees, were amenable to container production. Therefore, these species' growth and nitrogen, phosphorus, and potassium uptake efficiency and distribution under two fertilizer rates were studied. Malus trilobata seedlings were obtained from seeds collected from two mother trees, whereas Acer syriacum seeds were collected from a single tree. Two-year-old seedlings raised from these seeds were planted in 11-L containers in a 3:1 pine bark:compost substrate. Half the seedlings within each source and species were assigned to either 25 or 100 mg·L-1 N from 21N-3.1P-5.9K water-soluble fertilizer treatments. Seedlings of both Malus trilobata sources grown under 25 mg·L-1 N were taller than those grown at 100 mg·L -1 N. Nitrogen loading occurred in plants of Malus trilobata under the high fertilizer rate, although total plant N, phosphorus, and potassium content was unaffected by fertilizer rate, because larger seedlings had lower nutrient concentrations. There were significant differences in growth among the two Malus trilobata seed sources, but there were no differences in mineral nutrient uptake or nutrient use efficiency. Growth, mineral nutrient uptake, and nutrient use efficiency of Acer syriacum seedlings were unaffected by fertilizer rate. Malus trilobata and Acer syriacum seedlings are amenable to container production. Using container production for these species with subsequent transplanting into managed landscapes might be a viable ex situ conservation method. Further studies are needed.Drunasky Nicholas, 2005, Urban Forestry and Urban Greening, V4, P13; Evans G.C., 1972, QUANTITATIVE ANAL PL; GILLIAM CH, 1980, HORTSCIENCE, V15, P641; GILLIAM CH, 1984, J ENV HORT, V2, P53; Hillier and Sons, 1973, MAN TREES SHRUBS; INGESTAD T, 1979, PHYSIOL PLANTARUM, V45, P149, DOI 10.1111-j.1399-3054.1979.tb01679.x; Jull Laura G., 1994, Journal of Environmental Horticulture, V12, P212; Larimer Jill, 2002, Journal of Environmental Horticulture, V20, P28; Lumis Glen, 2000, Journal of Environmental Horticulture, V18, P13; MALIK V, 1995, CAN J FOREST RES, V25, P1017, DOI 10.1139-x95-110; MOUTERDE P, 1966, IMPRIMERIE CATHOLIQU, V1; MOUTERDE P, 1970, IMPRIMERIE CATHOLIQU, V2; Musselwhite Sheri, 2004, Journal of Environmental Horticulture, V22, P50; STOVEN A, 2004, THESIS OHIO STATE U; Struve Daniel K., 1995, Journal of Environmental Horticulture, V13, P169; Stubbs Hunter L., 1997, Journal of Environmental Horticulture, V15, P80; TISDALE S, 1998, SOIL FERTILITY FERTI; *UNEP, 1996, BIOL DIVERSITY LEBAN, V9; Wright R.D., 1987, HORTIC REV, V9, P75; Xu XJ, 1999, PLANT SOIL, V216, P83, DOI 10.1023-A:1004733714217; Zahreddine HG, 2007, SCI HORTIC-AMSTERDAM, V112, P80, DOI 10.1016-j.scienta.2006.11.013; ZAHREDDINE HG, 2007, LEBANESE SCI J, V8, P21; 1999, PRINCIPAUX ARBES LIB0
Geographic profiling in Nazi Berlin: fact and fiction
Geographic profiling uses the locations of connected crime sites to make inferences about the probable location of the offender’s ‘anchor point’ (usually a home, but sometimes a workplace). We show how the basic ideas of the method were used in a Gestapo investigation that formed the basis of a classic German novel about domestic resistance to the Nazis during the Second World War. We use modern techniques to re-analyse this case, and show that these successfully locate the Berlin home address of Otto and Elise Hampel, who had distributed hundreds of anti-Nazi postcards, after analysing just 34 of the 214 incidents that took place before their arrest. Our study provides the first empirical evidence to support the suggestion that analysis of minor terrorism-related acts such as graffiti and theft could be used to help locate terrorist bases before more serious incidents occur
Seed conditioning of red oak: a recalcitrant North American seed Condicionamento de sementes de carvalho vermelho: semente recalcitrante da América do Norte
A ten day aerated water soak was developed as a seed conditioning treatment for red oak (Quercus rubra L.). Conditioned seeds had higher germination completeness, uniformity and speed compared to control seeds. Seeds could be conditioned under a wide range of temperatures and durations. Conditioned seeds were maintained at 7(0)C for 30 days without loss of seed quality. During conditioning, pericarps split in response to seed hydration. Split pericarps could be used as a pre-sowing indicator for high quality seeds. Seed conditioning was ineffective on dormant seeds. Increased crop uniformity and higher stand establishment can be realized by subjecting red oak acorns to an aerated water soak treatment followed by selecting seeds with split pericarps. These results are especially important in container production systems where limited numbers of value seeds are available.Sementes de carvalho vermelho (Quercus rubra L.) foram condicionadas diretamente em água, sob aeração, durante 10 dias. As sementes condicionadas fisiologicamente apresentaram maior percentagem, velocidade e uniformidade de germinação, quando comparadas com a testemunha. O condicionamento das sementes pode ser efetuado sob ampla variação de temperaturas e períodos de exposição. Sementes condicionadas podem ser mantidas a 7ºC/30 dias, sem perda de qualidade. Durante o condicionamento ocorre ruptura do pericarpo, em resposta à hidratação da semente; essa ocorrência pode ser utilizada para estimar a qualidade da semente. O condicionamento não apresentou efeitos em sementes dormentes. O condicionamento das sementes de carvalho vermelho em água, com aeração, seguido pela seleção de sementes com ruptura do pericarpo, proporciona o rápido estabelecimento e uniformidade das plântulas

Designing for rehabilitation at home
New technologies open up possibilities for designing interactive experiences that can engage and motivate post-stroke survivors to undertake what would otherwise be boring repetitive movements. In this paper we outline a few of the challenges we met as part of the cross-disciplinary Motivating Mobility project. These are: the extended ‘user’; autonomy and motivation; and early prototype studies

Differential susceptibility of Iowa waterhemp (Amaranthus tuberculatus) populations to 2,4-D, dicamba, and glufosinate
Multiple herbicide-resistant waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) has limited herbicide options for Iowa row crop production. Soybean (Glycine max (L.) Merr.) cultivars and corn (Zea mays L.) hybrids resistant to 2,4-D, dicamba, and glufosinate have provided more herbicide options for waterhemp management. A probability-based survey of Iowa fields was conducted in fall 2019 wherein waterhemp seeds were collected and their susceptibility to 2,4-D, dicamba, and glufosinate was determined. The average survival of all populations treated with 1× 2,4-D, dicamba, and glufosinate was 17%, 5%, and 4%, respectively. Seven percent of treated populations exhibited ≥50% survival to 1× rates of 2,4-D.This article is published as Ryan C. Hamberg, Ramawatar Yadav, Micheal D.K. Owen, and Mark A. Licht.
