A bridge to nowhere: Methane emissions and the greenhouse gas footprint of natural gas

Howarth, R. W. (Wiley, 2014-05-14)

In April 2011, we published the first peer-reviewed analysis of the greenhouse gas footprint (GHG) of shale gas, concluding that the climate impact of shale gas may be worse than that of other fossil fuels such as coal and ...

A century of legacy phosphorus dynamics in a large drainage basin

McCrackin, M. L.; Muller-Karulis, B.; Gustafsson, B. G.; Howarth, R. W.; Humborg, C.; Svanbäck, A.; Swaney, D. P. (Wiley, 2018-06-27)

There is growing evidence that the release of phosphorus (P) from “legacy” stores can frustrate efforts to reduce P loading to surface water from sources such as agriculture and human sewage. Less is known, however, about ...

A cytogenetic analysis of reproduction in common shrews (Sorex araneus) from a karyotypic hybrid zone

Searle, J.B. (Mendelian Society of Lund, 1990-12)

Sixteen pregnant female common shrews were collected near Oxford (U.K.) from a hybrid zone between two karyotypic races which differ by Robertsonian rearrangements. Some females were homozygotes and others were ‘simple’ ...

A direct comparison of the consequences of plant genotypic and species diversity on communities and ecosystem function

Cook-Patton, Susan C.; McArt, Scott H.; Parachnowitsch, Amy L.; Thaler, Jennifer S.; Agrawal, Anurag A. (Ecological Society of America, 2011-04-01)

Biodiversity loss is proceeding at an unprecedented rate, yet we lack a thorough understanding of the consequences of losing diversity at different scales. While species diversity is known to impact community and ecosystem ...

A Field Experiment Demonstrating Plant Life-History Evolution and Its Eco-Evolutionary Feedback to Seed Predator Populations

Agrawal, Anurag A.; Johnson, Mark T.; Hastings, Amy P.; Maron, John L. (University of Chicago Press, 2013-05)

The extent to which evolutionary change occurs in a predictable manner under field conditions and how evolutionary changes feed back to influence ecological dynamics are fundamental, yet unresolved, questions. To address ...

A field test for the cues of diapause in a freshwater copepod

Hairston, Nelson G., Jr.; Dillon, Theresa A.; De Stasio, Bart T. (Ecological Society of America, 1990-12)

The freshwater calanoid copepod Diaptomus sanguineus switches each year in spring from making eggs that hatch immediately to making diapausing eggs that rest in lake sediments for an extended period. In lakes and ponds ...

A half-century of studies on a chromosomal hybrid zone of the house mouse

Giménez, M.D.; Förster, D.W.; Jones, E.P.; Jóhannesdóttir, F.; Gabriel, S.I.; Panithanarak, T.; Scascitelli, M.; Merico, V.; Garagna, S.; Searle, J.B.; Hauffe, H.C. (American Genetic Association, 2016-10-11)

The first natural chromosomal variation in the house mouse was described nearly 50 years ago in Val Poschiavo on the Swiss side of the Swiss–Italian border in the Central Eastern Alps. Studies have extended into neighboring ...

A northern glacial refugium for bank voles (Clethrionomys glareolus)

Kotlík, Petr; Deffontaine, Valérie; Mascheretti, Silvia; Zima, Jan; Michaux, Johan R.; Searle, Jeremy B. (Proceedings of the National Academy of Sciences of the USA, 2006-10-03)

There is controversy and uncertainty on how far north there were glacial refugia for temperate species during the Pleistocene glaciations and in the extent of the contribution of such refugia to present-day populations. ...

A voyage to Terra Australis: human-mediated dispersal of cats

Koch, K.; Algar, D.; Searle, J.B.; Pfenninger, M.; Schwenk, K. (BioMed Central, 2015-12-04)

BACKGROUND: Cats have been transported as human commensals worldwide giving rise to many feral populations. In Australia, feral cats have caused decline and extinction of native mammals, but their time of introduction and ...

Adaptive geographical clines in the growth and defense of a native plant

Woods, Ellen C.; Hastings, Amy P.; Turley, Nash E.; Heard, Stephen B.; Agrawal, Anurag A. (Ecological Society of America, 2012-05-01)

Broad?scale geographical gradients in the abiotic environment and interspecific interactions should select for clinal adaptation. How trait clines evolve has recently received increased attention because of anticipated ...

Age and survivorship of diapausing eggs in a sediment egg bank

Hairston, Nelson G., Jr.; Van Brunt, Robert A.; Kearns, Colleen M.; Engstrom, Daniel R. (Ecological Society of America, 1995-09)

We determined the densities of diapausing eggs of the copepod Diaptomnus sanguineas in sediments from two small freshwater lakes in Rhode Island. Sediment cores, sliced at 1-cm intervals, showed that egg densities ranged ...

An autosomal trisomic cell line in a wild common shrew (Sorex araneus)

Searle, J.B. (Springer Nature, 1989-04)

An Ecological and Evolutionary Framework for Commensalism in Anthropogenic Environments

Hulme-Beaman, A.; Dobney, K.; Cucchi, T.; Searle, J. B. (Elsevier, 2016-08)

Commensalism within anthropogenic environments has not been extensively discussed, despite its impact on humans, and there is no formal framework for assessing this ecological relationship in its varied forms. Here, we ...

Anthropogenic phosphorus inputs to a river basin and their impacts on riverine phosphorus fluxes along its upstream-downstream continuum

Zhang, W.S.; Swaney, D. P.; Hong, B.; Howarth, R. W. (Wiley, 2017-12-23)

The increasing trend in riverine phosphorus (P) loads resulting from anthropogenic inputs has gained wide attention because of the well-known role of P in eutrophication. So far, however, there is still limited scientific ...

Anthropogenic point-source and non-point-source nitrogen inputs into Huai River basin and their impacts on riverine ammonia–nitrogen flux

Zhang, W.S.; Swaney, D. P.; Li, X.Y.; Hong, B.; Howarth, R. W.; Ding, S.H. (Copernicus, 2015-07-22)

This study provides a new approach to estimate both anthropogenic non-point-source and point-source nitrogen (N) inputs to the landscape, and determines their impacts on riverine ammonia-nitrogen (AN) flux, providing a ...
