Induced plant defence and the evolution of counter-defences in herbivores
(Evolutionary Ecology, 2002)We examine how induced plant defences affect the evolution of resistance in herbivores (i.e. the ability to overcome plant defences) compared with constitutive defence strategies. Since resistance of herbivores may evolve ... -
Induction of Preference and Performance after Acclimation to Novel Hosts in a Phytophagous Spider Mite: Adaptive Plasticity?
(University of Chicago Press, 2001-10-29)We examined induction of preference and performance on novel host plants for two laboratory populations of the polyphagous spider mite Tetranychus urticae, with one population adapted to bean and the other population adapted ... -
Influence of prey availability and induced host-plant resistance on omnivory by western flower thrips
(Ecological Society of America, 1999-03-01)Theory predicts that the balance of nutritional needs, food availability, and the quality of particular food items are important factors in the feeding decisions of omnivorous animals. In this study we investigate factors ... -
Inputs of sediment and carbon to an estuarine ecosystem: Influence of land use
(Wiley, 1991-02-01)Estuaries and coastal marine ecosystems receive large inputs of nutrients, organic carbon, and sediments from non—point—source runoff from terrestrial ecosystems. In the tidal, freshwater Hudson River estuary, such inputs ... -
Intense Disturbance Enhances Plant Susceptibility to Herbivory: Natural and Experimental Evidence
(Ecological Society of America, 2003-04-01)Following Hurricane Lili, which passed directly over the site of our ongoing study in Great Exuma, Bahamas, herbivory increased on devastated islands exposed to the storm surge, but not on protected islands. Observations ... -
Invading and expanding: range dynamics and ecological consequences of the greater white-toothed shrew (Crocidura russula) invasion in Ireland
(Public Library of Science (PLOS), 2014-06-23)Establishing how invasive species impact upon pre-existing species is a fundamental question in ecology and conservation biology. The greater white-toothed shrew (Crocidura russula) is an invasive species in Ireland that ... -
Land-bridge calibration of molecular clocks and the post-glacial colonization of Scandinavia by the Eurasian field vole Microtus agrestis
(Public Library of Science (PLOS), 2014-08-11)Phylogeography interprets molecular genetic variation in a spatial and temporal context. Molecular clocks are frequently used to calibrate phylogeographic analyses, however there is mounting evidence that molecular rates ... -
Leaf Damage and Associated Cues Induce Aggressive Ant Recruitment in a Neotropical Ant-Plant
(Ecological Society of America, 1998-09-01)Induced chemical responses following herbivory are common in plants. Plant responses that change the level of physical or biotic defense are less well documented and poorly understood. Many Azteca spp. ants are obligate ... -
Linking environmental nutrient enrichment and disease emergence in humans and wildlife
(Wiley, 2010-01-10)Worldwide increases in human and wildlife diseases have challenged ecologists to understand how large-scale environmental changes affect host-parasite interactions. One of the most profound changes to Earth's ecosystems ... -
Love thy neighbor? Reciprocal impacts between plant community structure and insect herbivory in co-occurring Asteraceae
(Ecological Society of America, 2014-10-01)Patterns of herbivory may vary with fine?scale plant community structure: the degree of damage plants experience may depend on their neighbors (i.e., associational resistance or susceptibility). Differential herbivory, in ... -
Macroevolution and the biological diversity of plants and herbivores
(National Academy of Sciences, 2009-05-11)Terrestrial biodiversity is dominated by plants and the herbivores that consume them, and they are one of the major conduits of energy flow up to higher trophic levels. Here, we address the processes that have generated ... -
Mapping 3' transcript ends in the bank vole (Clethrionomys glareolus) mitochondrial genome with RNA-Seq
(Springer Nature, 2015-10-26)Background: Although posttranscriptional modification of mitochondrial (mt) transcripts plays key roles in completion of the coding information and in the expression of mtDNA-encoded genes, there is little experimental ... -
Meeting ecological and societal needs for freshwater
(Ecological Society of America, 2002-10)Human society has used freshwater from rivers, lakes, groundwater, and wetlands for many different urban, agricultural, and industrial activities, but in doing so has overlooked its value in supporting ecosystems. Freshwater ... -
Microsatellites for Oenothera gayleana and O. hartwegii subsp. filifolia (Onagraceae), and their utility in section Calylophus
(Botanical Society of America, 2016-02-09)Premise of the study: Eleven nuclear and four plastid microsatellite markers were screened for two gypsum endemic species, Oenothera gayleana and O. hartwegii subsp. filifolia, and tested for cross?amplification in the ... -
Natural selection on common milkweed (Asclepias syriaca) by a community of specialized insect herbivores
(Evolutionary Ecology, 2005)Hypothesis: Genetic variation in plant defence structures a community of herbivores and ultimately mediates co-evolution. Organisms: Common milkweed (Asclepias syriaca) and five natural insect herbivores (seed bug, leaf ... -
Nitrogen biogeochemistry of an urban rooftop farm
(Frontiers Media S.A., 2018-10-11)Intensive agriculture represents a recent extension of green roof technology. Perceived ecosystem services provided by rooftop farming include stormwater management and the production of affordable and nutritious vegetables ... -
Nitrogen fluxes from large watershed to coastal ecosystems controlled by net anthropogenic nitrogen inputs and climate
(Wiley, 2011-07-15)The flux of nitrogen (N) to coastal marine ecosystems is strongly correlated with the net anthropogenic nitrogen inputs (NANI) to the landscape across 154 watersheds, ranging in size from 16 km 2 to 279 000 km 2, in the ... -
Nonpoint pollution of surface waters with phosphorus and nitrogen
(Wiley, 1998-08-01)Agriculture and urban activities are major sources of phosphorus and nitrogen to aquatic ecosystems. Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrients are difficult to measure ... -
Nutrient limitation of phytoplankton growth in Vineyard Sound and Oyster Pond, Falmouth, Massachusetts
(University of Chicago Press, 2002-10)Intensive agriculture represents a recent extension of green roof technology. Perceived ecosystem services provided by rooftop farming include stormwater management and the production of affordable and nutritious vegetables ... -
Of mice and ‘convicts’: origin of the Australian house mouse, Mus musculus
(Public Library of Science (PLOS), 2011-12-12)The house mouse, Mus musculus, is one of the most ubiquitous invasive species worldwide and in Australia is particularly common and widespread, but where it originally came from is still unknown. Here we investigated this ...
