The chromosome number of 2n = 20 II reported here is the first determination for Hibiscadelphus giffardianus Rock and H. distans Bishop & Herbst. An earlier report of the same number for H. hualalaiensis Rock is substantiated. Cytogenetic analysis of H. x puakuahiwi Baker & Allen, a hybrid cross between H. giffardianus and H. hualalaiensis suggests that chromosome pairing and microsporogenesis ...

vs. C4 ), age of SOM, depth in the profile, and the amount of fossil fuel derived CO2 in the atmosphere (Shearer Although it is estimated that salinity stress occurs in 50% of irriand Kohl, 1986). However, since plants derive all their gated agroecosystems around the world, not much is known about its impact on C and N dynamics. This study was conducted to characC from the air, modeling 13C con...

The North American mid-continent population of Lesser snow geese (Chen caerulescens caerulescens L.) has increased by ca. 7% per year, largely as a result of geese feeding on agricultural crops in winter and on migration. We describe the long-term effects of increasing numbers of geese at an arctic breeding round (La P6rouse Bay, Manitoba) on intertidal salt-marsh vegetation. Between 1985 and 1...

With the exception of the undesirable characteristic of summer dormancy and the accompanying low aesthetic value, crested wheatgrass has many desirable characteristics in semiarid environments, making it a promising candidate for lower water use turf. Using a population of 27 half-sib families, this study characterized the underlying genetics of turf quality (based on a 1–9 rating scale) of cre...

In multiparty multimodal dialogue setup, where the robot is set to interact with multiple people, a main requirement for the robot is to recognize the user speaking to it. This would allow the robot to pay attention (visually) to the person the robot is listening to (for example looking by the gaze and head pose to the speaker), and to organize the dialogue structure with multiple people. Knowi...

Salt marshes provide valuable ecosystem services such as carbon sequestration, water purification and coastal protection (Barbier et al., 2011; Duarte 2013; Shepard 2011). The combination of these natural ecosystems with hard engineering like seawalls or dikes for the purpose is known ecosystem-based defence (Figure 1a). Considering projected rise in sea level increase storm intensity (IPCC, 20...

-The zone of natural Yacutia grasslands is situated between 60-64"N and 130-135"E. Vegetation of the meadow-steppe occupies vast glades dispersed in woodlands. These glades are inhabited by a dozen grasshopper species, three of which (Chorthippus albomarginatus, Aeropus sibiricus, and Omocestus haemorrhoidalis) are of economic importance. Most (up to 98%) of the grasshopper population consists ...
