Humans have had profound impacts on the ecology of North America both before and since colonization by Europeans. Modern-day human impacts extend to nearly every type of habitat, but evidence for pre-Columbian human impacts is limited almost exclusively to terrestrial ecosystems. In pre-Columbian times, human activities, especially burning and agriculture, transformed significant areas of North America (Delcourt and Delcourt 2004; Mann . 2005; see also Chapter 11 in this volume) and, in some… 

Biodiversity Loss in Freshwater Mussels: Importance, Threats, and Solutions

The loss of biodiversity worldwide has been well documented for decades, and while much of the attention of the media and scientific community has been focused on terrestrial ecosystems, other biomes

Freshwater mussel shells (Unionidae) chronicle changes in a North American river over the past 1000years.

The characteristics, spatial occurrence, timing, and potential causes of enigmatic mussel declines are reviewed and it is suggested that enigmatic declines represent a distinct, diagnosable phenomenon.

Drivers of ecosystem vulnerability to Corbicula invasions in southeastern North America

Invasive species introduction is one of the major ongoing ecological global crises. Identifying factors responsible for the success of invasive species is key for the implementation of effective

Spatial and Temporal Trends of Freshwater Mussel Assemblages in the Meramec River Basin, Missouri, USA

It was found that over 20y, species richness and diversity decreased significantly in the Bourbeuse and Meramec rivers but not in the Big River, while being extirpated from historical sampling sites more rapidly than colonizatio...


Abstract During 2009–2010, we qualitatively surveyed new and existing locations in the James River Basin, Missouri, to update the distribution and status of the freshwater mussel fauna and determine

Changes to freshwater mussel assemblages after 25 years of impoundment and river habitat fragmentation

The Tennessee–Tombigbee Waterway is among the largest and most expensive environmental engineering projects of the 20ᵗʰ century. The waterway accommodates barge navigation between the Tennessee River

The "cultural filter", human transport of mussel shell, and the applied potential of zooarchaeological data.

Different ways in which one kind of cultural bias, human transport of specimens, can be tested at different scales are discussed, using freshwater mussel shells from prehistoric sites in the Tombigbee River basin of Mississippi and Alabama to show how representativeness of samples can be assessed.

Drought-induced changes in flow regimes lead to long-term losses in mussel-provided ecosystem services

Mussel declines were exacerbated by human water management, which has increased the magnitude and frequency of hydrologic drought in downstream reaches of the river, and could have considerable consequences for downstream water quality although lost biofiltration and nutrient retention.



Biogeography of recently extinct marine species: Implications for conservation

At least fifteen marine and coastal animal species have become extinct since the end of the Pleistocene. Analyses of the number of marine biogeographical provinces occupied by these species show

Global trends in world fisheries: impacts on marine ecosystems and food security

This contribution, which reviews some broad trends in human history and in the history of fishing, argues that sustainability, however defined, rarely if ever occurred as a result of an explicit

Changing Perspectives on Pearly Mussels, North America's Most Imperiled Animals

Pearly mussel research has begun to benefit from and contribute to current ideas about suspension feeding, life-history theory, metapopulations, flow refuges, spatial patterning and its effects, and management of endangered species.

Ecosystem Collapse in Pleistocene Australia and a Human Role in Megafaunal Extinction

A 140,000-year record of dietary δ13C documents a permanent reduction in food sources available to the Australian emu, beginning about the time of human colonization; a change replicated at three widely separated sites and in the marsupial wombat.

Spatio-temporal patterns of the decline of freshwater mussels in the Little South Fork Cumberland River, USA

The river appears lost as a conservation refugium for mussels despite its remoteness, predominantly forested watershed, and several layers of existing statutory and regulatory environmental safeguards, it is suggested that the river could be restored and mussels reintroduced if an interagency task force is formed to identify and mitigate specific stressors now affecting most mussel species in the river.

Complex trophic interactions in kelp forest ecosystems

It is hypothesized that killer whales sequentially “fished down” pinniped and sea-otter populations after their earlier prey, the great whales, were decimated by commercial whaling.
