Abstract Aim Within fluvial and coastal ecosystems world‐wide, flows of water, wind sediment generate a shifting landscape mosaic composed bare substrate pioneer mature vegetation successional stages. Pioneer plant species that colonize these at the land–water interface have developed specific traits in response to environmental constraints (response traits) are able modify habitat conditions by modulating geomorphic processes (effect traits). Changes environment under control engineer...
Abstract Studies of dune vegetation patterns have emphasized two structuring agents: local environmental gradients that shape the prominent zonation coastal plant species, and disturbance patches initiated by overwash during storms. For systems barrier islands in Georgia Bight, we investigate how interplay these conceptual frames generate (1) longitudinal (along-shore) transverse (across-shore) compositional variability (2) arrangement species along gradients. We describe this constitutes a...
Barrier islands are heavily influenced by external drivers such as sea-level rise, storm-related disturbances, and other complex factors that affect net sediment exchange. Numerous ecological processes (e.g., dispersal, competition, facilitation) interact with these ultimately influence barrier-island state change therefore stability. Our synthesis of physical controlling function highlights the importance incorporating into predictive models change. We present a conceptual framework...
Abstract Scientific narratives surrounding colony collapse disorder (CCD) are often played against one another. However, oppositional knowledge politics do not neatly segregate the materiality and causal properties of ecological phenomena they represent. Thus challenge with CCD is just to describe partisan character how about it socially produced. It also integrate these through their less antagonistic material ecologies. We review three dominant discourses underlying honey bee decline...
Abstract This study explores how the Atlanta, Georgia (United States), urban region influences warm-season (May through September) cloud-to-ground lightning flashes and precipitation. Eight years (1995–2003) of from National Lightning Detection Network mean accumulated precipitation North American Regional Reanalysis model were mapped under seven different wind speed direction combinations derived cluster analysis. Overlays these data affirmed a consistent coupling enhancement around...
Abstract Due to their position at the land–sea interface, barrier islands are vulnerable both oceanic and atmospheric climate change‐related drivers. In response relative sea‐level rise, tend migrate landward via overwash processes which deposit sediment onto backbarrier marsh, thus maintaining elevation above sea level. this paper, we assess importance of interior upland vegetation transport (from marsh) on movement marsh–upland boundary in a transgressive system along mid‐Atlantic Coast....
Abstract This review of urban lightning research begins with a description cloud‐to‐ground flash data and some the conditioning practices related to their use. Urban studies from United States internationally are then examined distill findings as well compare contrast modes inquiry among meteorologists, climatologists, engineers, geographers who study lightning. In summary, these investigations convey how heating, building‐induced surface friction, aerosols, specificities such local...
Abstract The Apalachicola–Chattahoochee–Flint (ACF) River basin is an important ecological and economic component of a three‐state region (Florida, Alabama Georgia) in the southeastern U.S. Along Apalachicola northwest Florida, duration floodplain inundation has decreased as result declining river levels. Spring summer flows have diminished volume because water use, storage evaporation reservoirs, other anthropogenic climatic changes upstream. Channel erosion from dam construction navigation...
Abstract The distribution of warm season (June through August) thunderstorm activity surrounding Atlanta, Georgia from 1997 to 2006 was determined utilizing composite reflectivity data obtained the network National Weather Service radars. radar data, at 2 km and 5 min spatial temporal resolutions, allows for high resolution analyses urban convective trends when grid averaged over a 10‐year period. Maxima medium‐ high‐reflectivity episodes were identified north within downtown Atlanta...
Abstract An examination of synoptic environments conducive to urban thunderstorm development surrounding Atlanta, Georgia, was conducted. Synoptic environmental characteristics were evaluated utilising regional analyses heights, winds, temperature, and moisture as well several thermodynamic variables. A flexible beta cluster analysis used in order identify disparate groupings common environments. These then further analysed through the production composites, radar, lightning distributions....
A 12-year climatology of lightning cloud-to-ground flash activity for Georgia revealed the existence three primary regions high activity: area surrounding Atlanta Metropolitan Statistical Area, east-central along fall line, and Atlantic coast. Over 8.2 million ground flashes were identified during climatology. July was most active month December least active. Annual, seasonal, diurnal distributions also examined. These patterns illustrated interacting effects land cover, topography,...
Shifts in the hydrologic regime of Florida's Apalachicola River have been attributed to anthropogenic changes throughout its watershed, including local dam construction. To assess impacts those shifts on floodplain forests, we reconstructed tree growth using dendrochronology and compared these trends with hydrological climatic variables. Comparisons stream-gage data before after construction revealed statistically significant mean declines annual average stage. Mean minimum stages, rise...
Barrier island dunes are postulated to exhibit two states, or stability domains. In this model, transitions between domains can irreversibility. However, these may also be bistable, whereby the topography of either domain develop at a location. To infer evidence for dynamical properties and link them dune topography, statistical mapping topographic state space was undertaken six barrier islands southeastern U.S. Atlantic coast. Topographies three four plots per were constructed from airborne...
Abstract Eight Midwestern extremely high dew point events were examined with respect to their synoptic characteristics and evolution. Individual composite analyses of suggest that there exists three predominant features associated extreme events. In nearly all cases, the evolution environment includes development propagation low pressure from plains through upper Great Lakes. The increases backs surface winds acting advect low‐level moisture eastern Nebraska, Iowa, Missouri eastward into...
