The effect of climate change on phenology and growth is less understood for belowground plant tissues than aboveground tissues, particularly in high-latitude regions. Ecotypes within a species adapted to locality may display different responses change. We established two common garden plots the Arctic tundra north Brooks Range northern Alaska. Three ecotypes Eriophorum vaginatum along latitudin...

We measured community-level traits of vascular plants, lichens, and bryophytes in an alpine Dryas octopetala L. heath Finse, Norway, after nearly two decades experimental warming by open-top chambers. hypothesized that under (1) plant would shift from resource conservative towards more acquisitive, (2) lichen bryophyte to those associated with drier conditions, due increased evapotranspiration....

OBJECTIVE To evaluate the accuracy and diagnostic usefulness of a disposable flowmeter consisting of a plastic funnel with a spout divided into three chambers. MATERIALS AND METHODS Men with lower urinary tract symptoms (LUTS) voided sequentially into a standard flowmeter and the funnel device recording maximum flow rate (Q(max)) and voided volume (V(void)). The device was precalibrated such ...

Herbicide resistant weed populations have developed due to the repeated application of herbicides. Elevated concentrations of atmospheric CO2 can have positive effects on weed growth, but how rising CO2 might affect herbicide resistant weeds is not known. Ragweed (Ambrosia artemisiifolia L.) ecotypes known to be resistant or susceptible to glyphosate herbicide were exposed to either ambient or ...

background: although the depth of the counting chamber is an important factor influencing sperm counting, no research has yet been reported on the measurement and comparison of the depth of the chamber. we measured the exact depths of six kinds of sperm counting chambers and evaluated their accuracy. materials and methods: in this prospective study, the depths of six kinds of sperm counting cha...

Detached leaves at top canopy structures always experience higher solar irradiance and leaf temperature under natural conditions. The ability of tolerance to high temperature represents thermotolerance potential of whole-plants, but was less of concern. In this study, we used a heat-tolerant (B76) and a heat-susceptible (B106) maize inbred line to assess the possible mitigation of sudden heat s...

Ozone (O3) pollution is accompanied by drought stress, especially at high temperatures. Tree species in cities often face dual stresses from O3 and drought. In this study, Acer rubrum ‘Autumn Blaze’ A. pictum were used as test plants open-top-chambers (OTCs) to investigate the trees most tolerant increasing urban gardens. The results showed that induced a change rubrum’s leaf coloration green r...

The hybrids of ATLAS semi-conductor tracker (SCT) were made with Cu/Polyimide flex-circuits, reinforced with carbon-carbon substrates, in the barrel and in the endcap modules. We report successes, problems and solutions in the course of production of 2600 pieces of hybrids each.

The Florida harvester ant, Pogonomyrmex badius, is one of many ant species and genera that stores large numbers of seeds in damp, underground chambers for later consumption. A comparison of the sizes of seeds recovered from storage chambers with those of seed husks discarded following consumption revealed that the used seeds are far smaller than stored seeds. This difference in use-rate was con...
