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 ... -
Over a Thousand Years of Evolutionary History of Domestic Geese from Russian Archaeological Sites, Analysed Using Ancient DNA
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-07-20)The European domestic goose is a widely farmed species known to have descended from the wild greylag goose (Anser anser). However, the evolutionary history of this domesticate is still poorly known. Ancient DNA studies ... -
Partial photoperiodic control of diapause in three populations of the freshwater copepod Diaptomus sanguineus
(University of Chicago Press, 1986-08)Populations of the freshwater calanoid copepod Diaptomus sanguineus inhabiting three Rhode Island ponds switch from making subitaneous (immediately hatching) to diapausing eggs on different dates. From results of previous ... -
Pericentromeric organization at the fusion point of mouse Robertsonian translocation chromosomes
(Proceedings of the National Academy of Sciences of the USA, 2001-01-02)In mammals, Robertsonian (Rb) translocation (the joining of two teloy acrocentric chromosomes at their centromere to form a metacentric) is the most effective process in chromosomal evolution leading to speciation; ... -
Phenotypic variation across chromosomal hybrid zones of the common shrew (Sorex araneus) indicates reduced gene flow
(Public Library of Science (PLOS), 2013-07-10)Sorex araneus, the Common shrew, is a species with more than 70 karyotypic races, many of which form parapatric hybrid zones, making it a model for studying chromosomal speciation. Hybrids between races have reduced fitness, ... -
Phenotypic variation in a zooplankton egg bank
(Ecological Society of America, 1996-12)Dormant propagule pools may store potentially significant genetic variation that can influence the rate and direction of microevolution via directional selection, tem- porally fluctuating selection, and evolution of trait ... -
Photoprotection by carotenoid pigments in the copepod Diaptomus nevadensis
(National Academy of Sciences, 1976-03)Individuals of the copepod Diaptomus nevadensis that contain high concentrations of carotenoids survive significantly better in natural intensities of visible light than less pigmented copepods. Vertical migration and ... -
Phylogenetic and Experimental Tests of Interactions among Mutualistic Plant Defense Traits in Viburnum (Adoxaceae)
(University of Chicago Press, 2012-10)Plant traits that mediate mutualistic interactions are widespread, yet few studies have linked their macroevolutionary patterns with the ecological interactions they mediate. Here we merged phylogenetic and experimental ... -
Phylogenetic escalation and decline of plant defense strategies
(National Academy of Sciences, 2008-07-22)As the basal resource in most food webs, plants have evolved myriad strategies to battle consumption by herbivores. Over the past 50 years, plant defense theories have been formulated to explain the remarkable variation ... -
Phylogeny of the plant genus Pachypodium (Apocynaceae)
(PeerJ, 2013-04-23)Background. The genus Pachypodium contains 21 species of succulent, generally spinescent shrubs and trees found in southern Africa and Madagascar. Pachypodium has diversified mostly into arid and semi-arid habitats of ...
