Much uncertainty exists about the vulnerability of valuable tidal marsh ecosystems to relative sea level rise. Previous assessments resilience rise, which marshes can adjust by sediment accretion and elevation gain, revealed contrasting results, depending on contemporary or Holocene geological data. By analyzing globally distributed data, we found that increases in parity with seemingly confirming previously claimed resilience. However, subsidence substrate shows a nonlinear increase...
Abstract Several coastal ecosystems—most notably mangroves and tidal marshes—exhibit biogenic feedbacks that are facilitating adjustment to relative sea-level rise (RSLR), including the sequestration of carbon trapping mineral sediment 1 . The stability reef-top habitats under RSLR is similarly linked reef-derived accumulation vertical accretion protective coral reefs 2 persistence these ecosystems high rates contested 3 Here we show probability inferred from palaeo-stratigraphic...
Habitat destruction is a leading cause of biodiversity loss worldwide. Destruction involving structural simplification tends to be large contributing factor this as many studies have reported positive relationship between habitat complexity and taxonomic richness. However, the aspects that are most important for still unclear. We tested whether several attributes contribute significantly effects on macroinvertebrate sampled macroinvertebrates associated with species macrophytes covering wide...
Abstract Invasive species represent a threat to aquatic ecosystems globally; however, impacts can be heterogenous across systems. Documented of invasive zebra mussels ( Dreissena polymorpha ) and spiny water fleas Bythotrephes cederströmii ; hereafter on native fishes are variable context dependent locations time periods. Here, we use hierarchical Bayesian analysis 35-year dataset two fish from 9 lakes demonstrate that early life growth ecologically important influenced by these species....
Quantifying the relationship between phytoplankton and zooplankton may offer insight into sensitivity to shifting assemblages potential impacts of producer-consumer decoupling on rest food web. We analyzed 18 years (2001-2018) paired samples collected as part United States Environmental Protection Agency (U.S. EPA) Great Lakes Biology Monitoring Program examine both long-term seasonal relationships across all five Laurentian Lakes. also effects diversity biomass, diversity, predator-prey...
Biological attributes of ecosystems often change nonlinearly as a function anthropogenic and natural stress. Plant animal communities may exhibit zones along stressor gradient that are disproportionate relative to the incremental in stressor. The ability predict such transitions is essential for effective management intervention because they indicate irreversible changes ecological processes. Despite importance recognizing transition gradient, few, if any, investigators have examined these...
1. The control of invasive species has become a widespread management practice, yet information on the community effects such efforts is very limited, there no unified framework for monitoring their success and guidelines exist to help minimize potential adverse impacts. 2. This study was conducted determine how long-term macrophyte, Eurasian watermilfoil, affect native macrophytes, fish macroinvertebrates. In addition, we examined members aquatic fauna respond changes in macrophyte...
Watershed-scale anthropogenic stressors have profound effects on aquatic communities. Although several functional traits of stream macroinvertebrates change predictably in response to land development and urbanization, little is known about macroinvertebrate responses lakes. We assessed community structure, diversity (Rao's quadratic entropy) voltinism communities sampled across the full gradient stress Laurentian Great Lakes coastal wetlands. Functional significantly decreased with...
Boreal wetlands play an important role in global carbon balance. However, their ecosystem function is threatened by direct anthropogenic disturbance and climate change. Oil sands surface mining the boreal regions of Western Canada denudes tracts land organic materials, leaves large areas need reclamation, generates considerable quantities extraction process-affected materials. Knowledge validation reclamation techniques that lead to self-sustaining has lagged behind development protocols for...
