Models predict that precipitation variability will increase with climate change. We used a 15-year precipitation manipulation experiment to determine if altering the timing and amount of growing season rainfall will impact plant community structure in annually burned, native tallgrass prairie. The altered precipitation treatment maintained the same total growing season precipitation as the ambi...

Cyclical parthenogens, which combine asexual and sexual reproduction, are good models for research into the ecological and population processes affecting the evolutionary maintenance of sex. Sex in cyclically parthenogenetic rotifers is necessary for diapausing egg production, which is essential to survive adverse conditions between planktonic growing seasons. However, within a planktonic seaso...

This study identified statistically significant, and practically important, seasonal pheromone trap response dynamics of Euschistus conspersus (Uhler) in processing tomatoes in 12 fields over 5 years in California, USA. Commercial fields were monitored weekly using traps baited with Euschistus spp. pheromone and direct canopy shake samples. Regression analysis determined no significant relation...

The seasonal dynamics of plant N assimilation and microbial N immobilization were studied in an alpine ecosystem to evaluate temporal patterns of plant and microbial N partitioning and the potential for plant vs. microbial competition for N. Plant N uptake was higher in the first half of the growing season than later in the season, as indicated by changes in biomass N and by 15N uptake. Microbi...

In order to investigate the effects of canopy-dependent processes on throughfall chemistry, comparative studies on the chemical composition of throughfall were carried out in five characteristic forest types of the southeastern United States within Fort Benning Military Installation from January 2002 to August 2003. The concentrations and fluxes of and total organic carbon (TOC), total Kjeldahl...

Seedlings and vegetative ramets may contribute differentially to the recruitment of clonal populations in different growth phases, but this has rarely been investigated. In this study, we quantified the number and survivorship of seedlings and vegetative ramets monthly in juvenile and mature populations of Carex brevicuspis. During the first growing season after flooding (from October to Januar...

Analyses of climate change based on point observations indicate an extension the plant growing season, which may have impact production and functioning natural ecosystems. involving remote sensing methods, added more detail to results obtained in traditional way, been carried out only since 1980s. The paper presents a bibliometric analysis papers related season published from 2000–2021 included...

Soil respiration of terrestrial ecosystems, a major component in the global carbon cycle is affected by elevated atmospheric CO2 concentrations. However, seasonal differences of feedback effects of elevated CO2 have rarely been studied. At the Gießen Free-Air CO2 Enrichment (GiFACE) site, the effects of +20 % above ambient CO2 concentration have been investigated since 1998 in a temperate grass...
