Summary To determine to which extent root‐derived carbon contributes to the effects of plants on nitrate reducers and denitrifiers, four solutions containing different proportions of sugar, organic acids and amino acids mimicking maize root exudates were added daily to soil microcosms at a concentration of 150 μg C g −1 of soil. Water‐amended soils were used as controls. After 1 month, the size and structure of the nitrate red...

Bottlenose dolphins ( Tursiops truncatus ) along the Gulf of Mexico are frequently exposed to blooms of the toxic alga, Karenia brevis , and brevetoxins associated with these blooms have been implicated in several dolphin mortality events. Studies on brevetoxin accumulation in dolphins have typically focused on analyses of carcasses from large‐scale die‐offs; however, data are scarce for brevetoxin loads in live individuals fr...

Changes in temperature, precipitation, and other climatic drivers and sea‐level rise will affect populations of existing native and non‐native aquatic species and the vulnerability of aquatic environments to new invasions. Monitoring surveys provide the foundation for assessing the combined effects of climate change and invasions by providing baseline biotic and environmental conditions, although the utility of a survey depend...
