Distribution of Ice Nucleation-Active (INA) Bacteria from Rain-water and Air

open access: yes, 2011
Certain bacteria that induce biological ice nucleation are suspected to play an important role in condensation and ice nuclei formation in clouds. Those bacteria can produce biological ice nucleator1, which is a protein and usually found on leaf surface ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

Rain water and through fall chemistry in silent valley forest in South India

open access: yes, 1995
Rain water and throughfall samples were collected at the Silent Valley forest during the two consecutive southwest summer monsoon seasons (June–September) of 1989 and 1990. All the samples were analysed for Cl−, SO42−, NO3−, NH4+, Na+, K+, Ca2+, Mg2+ and

Soil salinity effects on pollen and pollinator visitation in a buzz‐pollinated glycophyte, Solanum carolinense

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.

Collection and treatment of rain water runoff in the vicinity of municipal water intakes

open access: yes, 2001
Polluted rain water runoffs have always raised serious environmental problems especially in the vicinity of intakes for municipal water supply. Rain water is known to carry a considerable load of organic and mineral pollutants (TOC, nitrogen, phosphorus,

Annual rain-water over India, its variability and impact on the economy.

open access: yes, 1981
The total volume of rain-water over India has been computed for each of the years during the period 1871-1978 on the basis of the rainfall data for a fixed network of 306 raingauges.

Ion-chromatographic monitoring of main components of rain water in industrial and rural sites in Germany

open access: yes, 2002
The paper discusses long-term changes in concentrations of major inorganic ions in rain water collected in urban and rural areas in Germany. Ion chromatography with conductivity detection is applied for the chemical analysis of precipitation samples.
