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 ... -
Data from: A private channel of nitrogen alleviates interspecific competition for an annual legume
(2021-05-24)The way resource availability predictably alters interspecific interactions and may favor one resource-acquisition strategy over another is critical for understanding context dependency. The ubiquity of nitrogen (N) ... -
Data from: Consumer-resource dynamics is an eco-evolutionary process in a natural plankton community
(2019)For an important consumer-resource interaction in a natural lake (Oneida Lake, New York State) in 2015, the ecological process of grazer population growth rate was a function of both evolutionary changing mean resistance ... -
Data from: Developmental temperature predicts the adult response to stressors in a free-living passerine
(2019)Early life conditions can have substantial effects on the ways animals respond to stressors as adults. In particular, thermal conditions during development affect juveniles’ responses to stressors, and there is evidence ... -
Deer Browsing Delays Succession by Altering Aboveground Vegetation and Belowground Seed Banks
(PLOS, 2014-03-07)Soil seed bank composition is important to the recovery of natural and semi-natural areas from disturbance and serves as a safeguard against environmental catastrophe. White-tailed deer (Odocoileus virginianus) populations ... -
Defense mutualisms enhance plant diversification
(National Academy of Sciences, 2014-09-22)The ability of plants to form mutualistic relationships with animal defenders has long been suspected to influence their evolutionary success, both by decreasing extinction risk and by increasing opportunity for speciation ... -
Direct and interactive effects of enemies and mutualists on plant performance: A meta-analysis
(Ecological Society of America, 2007-04-01)Plants engage in multiple, simultaneous interactions with other species; some (enemies) reduce and others (mutualists) enhance plant performance. Moreover, effects of different species may not be independent of one another; ... -
Divergent evolutionary processes associated with colonization of offshore islands
(Wiley, 2013-10-10)Oceanic islands have been a test ground for evolutionary theory, but here, we focus on the possibilities for evolutionary study created by offshore islands. These can be colonized through various means and by a wide range ... -
Do plant defenses predict damage by an invasive herbivore? A comparative study of the viburnum leaf beetle
(Ecological Society of America, 2014-06-01)The impact of plant defenses on insect herbivores is widely accepted, but their relative effects on oviposition choice, survival, and larval growth in preventing pest damage, especially for invasive insects, is not fully ... -
Does food web complexity eliminate trophic-level dynamics?
(University of Chicago, 1997-05) -
Dual mechanism of chromatin remodeling in the common shrew sex trivalent (XY1Y2)
(Pensoft Publishers, 2017-11-03)Here we focus on the XY1Y2 condition in male common shrew Sorex araneus Linnaeus, 1758, applying electron microscopy and immunocytochemistry for a comprehensive analysis of structure, synapsis and behaviour of the sex ... -
Effects of varying salinity on phytoplankton growth in a low-salinity coastal pond under two nutrient conditions
(University of Chicago Press, 2002-10)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 ... -
Enemy release? An experiment with congeneric plant pairs and diverse above- and belowground enemies
(Ecological Society of America, 2005-11-01)Several hypotheses proposed to explain the success of introduced species focus on altered interspecific interactions. One of the most prominent, the Enemy Release Hypothesis, posits that invading species benefit compared ... -
Enhancing diversity in undergraduate science: self-efficacy drives performance gains with active learning
(American Society for Cell Biology, 2017-12-01)Efforts to retain underrepresented minority (URM) students in science, technology, engineering, and mathematics (STEM) have shown only limited success in higher education, due in part to a persistent achievement gap between ... -
Estimating net anthropogenic nitrogen inputs (NANI) in the Lake Dianchi basin of China
(Copernicus, 2014-08-28)Net anthropogenic nitrogen inputs (NANI) with components of atmospheric N deposition, synthetic N fertilizer, agricultural N fixation and N in net food and feed imports from 15 catchments in the Lake Dianchi basin were ... -
Evidence for adaptive radiation from a phylogenetic study of plant defenses
(National Academy of Sciences, 2009-10-27)One signature of adaptive radiation is a high level of trait change early during the diversification process and a plateau toward the end of the radiation. Although the study of the tempo of evolution has historically been ... -
Evolution of Plant Growth and Defence in a Continental Introduction
(University of Chicago Press, 2015-07)Substantial research has addressed adaptation of nonnative biota to novel environments, yet surprisingly little work has integrated population genetic structure and the mechanisms underlying phenotypic differentiation in ... -
Evolution of Specialization: A Phylogenetic Study of Host Range in the Red Milkweed Beetle (Tetraopes tetraophthalmus)
(University of Chicago Press, 2011-05-03)Specialization is common in most lineages of insect herbivores, one of the most diverse groups of organisms on earth. To address how and why specialization is maintained over evolutionary time, we hypothesized that plant ... -
Evolutionary history predicts plant defense against an invasive pest
(National Academy of Sciences, 2011-02-22)It has long been hypothesized that invasive pests may be facilitated by the evolutionary naïveté of their new hosts, but this prediction has never been examined in a phylogenetic framework. To address the hypothesis, we ... -
Exotic plants contribute positively to biodiversity functions but reduce native seed production and arthropod richness
(Ecological Society of America, 2014-06-01)Although exotic plants comprise a substantial portion of floristic biodiversity, their contributions to community and ecosystem processes are not well understood. We manipulated plant species richness in old?field communities ...
