A comprehensive field and modeling study indicates vulnerability of tidal wetlands to sea-level rise on the U.S. Pacific coast.
Salt marsh elevation and geomorphic stability depends on mineral sedimentation. Many Mediterranean-climate salt marshes along southern California, USA coast import sediment during El Niño storm events, but fluxes mechanisms dry weather are potentially important for stability. We calculated tidal creek within a highly modified, sediment-starved, 1.5-km2 (Seal Beach) less modified 1-km2 (Mugu) with fluvial supply. measured plain suspended concentration vertical accretion using single stage...
Abstract Sea‐level rise ( SLR ) impacts on intertidal habitat depend coastal topology, accretion, and constraints from surrounding development. Such changes might affect species like Belding's savannah sparrows Passerculus sandwichensis beldingi ; BSSP ), which live in high‐elevation salt marsh the Southern California Bight. To predict how change under various scenarios, we first constructed a suitability model by matching bird observations with elevation. We then mapped current breeding...
Within isolated and fragmented populations, species interactions such as predation can cause shifts in community structure demographics tidal marsh ecosystems. It is critical to incorporate into our understanding when evaluating the effects of sea-level rise storm surges on marshes. In this study, we hypothesize that avian predators will increase their presence hunting activities during high tides increased inundation makes prey more vulnerable. We present evidence there a relationship...
Abstract This paper presents the first record of fire in Pacific coast salt marshes; 1993 Green Meadows Fire and 2013 Camarillo Springs burned an area Salicornia -dominated marsh at Point Mugu, CA. These fires inspire concern about resiliency ecosystems not adapted to fire, already threatened by sea-level rise (SLR), under stress from extreme drought. We monitored vegetation percent cover, diversity, soil organic carbon (SOC) unburned areas following used remotely sensed Normalized...
In data-poor regions, modeled river temperatures are essential for predicting potential stressors species at risk. With limited data from the Grand, Thames, and Sydenham rivers in southern Ontario, Canada, we evaluated simple mixed-effect regression models to predict water temperature using air nearby weather stations. Model performance was assessed periods relevant fitness of black redhorse (Moxostoma duquesni): June August, when heat events may be likely; May, spawning occurs. All...
