Anthropogenic point-source and non-point-source nitrogen inputs into Huai River basin and their impacts on riverine ammonia–nitrogen flux
(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 ... -
Asymmetric energetic costs in reciprocal-cross hybrids between carnivorous mice (Onychomys)
(The Company of Biologists Ltd., 2016-12-01)Aerobic respiration is a fundamental physiological trait dependent on coordinated interactions between gene products of the mitochondrial and nuclear genomes. Mitonuclear mismatch in interspecific hybrids may contribute ... -
Behavioral responses of the endemic shrimp Halocardina rubra (Malacostraca:Atyidae) to an introduced fish, Gambusia affinis (Actinopterygii: Poeciliidae) and implications for the trophic structure of Hawaiian anchialine ponds
(University of Hawai'i Press, 2009-01)In the Hawaiian Islands, intentionally introduced exotic fishes have been linked to changes in native biodiversity and community composition. In 1905, the mosquito fish Gambusia affinis was introduced to control mosquitoes. ... -
BENEFITS AND COSTS OF INDUCED PLANT DEFENSE FOR LEPIDIUM VIRGINICUM (BRASSICACEAE)
(Ecological Society of America, 2000-07)Induced responses to herbivores are common and well documented in plants. It has been hypothesized that the evolutionary ecology of induced responses can be understood by studying benefits of induction in the presence of ... -
Benthic macroinvertebrate functional diversity regulates nutrient and algal dynamics in a shallow estuary
(Inter-Research Science Publishing, 2011-03-28)Proliferation of macroalgal blooms is regulated by grazing pressure and nutrient availability, which may be mediated directly by benthic macroinvertebrates or indirectly through feedback mechanisms. Using invertebrates ... -
Between the Balkans and the Baltic: phylogeography of a common vole mitochondrial DNA lineage limited to central Europe
(Public Library of Science, 2016-12)The common vole (Microtus arvalis) has been a model species of small mammal for studying end-glacial colonization history. In the present study we expanded the sampling from central and eastern Europe, analyzing contemporary ... -
Cardenolides, induced responses, and interactions between above? and belowground herbivores of milkweed (Asclepias spp.)
(Ecological Society of America, 2009-09-01)Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above? and belowground plant defenses been considered simultaneously. Milkweeds in the genus Asclepias are a ... -
Cause-effect relationships in energy flow, trophic structure, and interspecific interactions
(University of Chicago, 1993-09)Measurements of the efficiency of energy transfer between trophic levels are consis- tent with the hypothesis that it is trophic structure that controls the fraction of energy consumed at each trophic level, rather than ... -
Changes in anthropogenic nitrogen and phosphorus inputs to the St. Lawrence Basin over 110 years: Impacts on riverine export
(Wiley, 2016-07-06)Human activities have increased the flow of nitrogen (N) and phosphorus (P) over much of the Earth, leading to increased agricultural production, but also the degradation of air, soil, and water quality. Here we quantify ... -
Chromosome synapsis and recombination in male hybrids between two chromosome races of the common shrew (Sorex araneus L., Soricidae, Eulipotyphla)
(Multidisciplinary Digital Publishing Insitute (MDPI), 2017-10-20)Hybrid zones between chromosome races of the common shrew (Sorex araneus) provide exceptional models to study the potential role of chromosome rearrangements in the initial steps of speciation. The Novosibirsk and Tomsk ... -
Coastal marine eutrophication: Control of both nitrogen and phosphorus is necessary
(PNAS, 2008-12-09)Human activities have clearly caused dramatic alterations of the terrestrial nitrogen cycle, and analyses of the extent and effects of such changes are now common in the scientific literature. However, any attempt to ... -
Coexistance of three specialist aphids on common milkweed, Asclepias syriaca
(Ecological Society of America, 2008-08-01)Coexistence of host?specific herbivores on plants is believed to be governed by interspecific interactions, but few empirical studies have systematically unraveled these dynamics. We investigated the role of several factors ... -
Colonization, mouse-style
(BioMed Central, 2010-10-26)Several recent papers, including one in BMC Evolutionary Biology, examine the colonization history of house mice. As well as background for the analysis of mouse adaptation, such studies offer a perspective on the history ... -
Community heterogeneity and the evolution of interactions between plants and insect herbivores
(University of Chicago Press, 2006-12)Plant communities vary tremendously in terms of productivity, species diversity, and genetic diversity within species. This vegetation heterogeneity can impact both the likelihood and strength of interactions between plants ... -
Community-wide convergent evolution in insect adaptation to toxic cardenolides by substitutions in the NA,K-ATPase
(University of Chicago Press, 2012-06-19)The extent of convergent molecular evolution is largely unknown, yet is critical to understanding the genetics of adaptation. Target site insensitivity to cardenolides is a prime candidate for studying molecular convergence ... -
Community-wide impacts of herbivore-induced plant responses in milkweed (Asclepias syriaca)
(Ecological Society of America, 2004-09-01)The effects of early?season herbivory and subsequent induced plant responses have the potential to affect the diversity of herbivorous insect communities. We investigated the seasonal development of the herbivore fauna on ... -
Consequences of toxic secondary compounds in nectar for mutualist bees and antagonist butterflies
(Ecological Society of America, 2016-06-06)Attraction of mutualists and defense against antagonists are critical challenges for most organisms and can be especially acute for plants with pollinating and non?pollinating flower visitors. Secondary compounds in flowers ... -
Coupled biogeochemical cycles: eutrophication and hypoxia in temperate estuaries and coastal marine ecosystems
(Wiley, 2011-02-01)Nutrient fluxes to coastal areas have risen in recent decades, leading to widespread hypoxia and other ecological damage, particularly from nitrogen (N). Several factors make N more limiting in estuaries and coastal waters ... -
Cryptic population dynamics: rapid evolution masks trophic interactions
(Public Library of Science (PLOS), 2007-09)Trophic relationships, such as those between predator and prey or between pathogen and host, are key interactions linking species in ecological food webs. The structure of these links and their strengths have major ... -
Cyanobacteria facilitate parasite epidemics in Daphnia
(Ecological Society of America, 2016-12)The seasonal dominance of cyanobacteria in the phytoplankton community of lake ecosystems can have severe implications for higher trophic levels. For herbivorous zooplankton such as Daphnia, cyanobacteria have poor nutritional ...
