Data for Rapid phenotypic differentiation and local adaptation in Japanese knotweed s.l. (Reynoutria japonica and R. × bohemica, Polygonaceae) invading novel habitats

Christina Richards
PREMISE: Many plant invaders like the Japanese knotweeds are thought to colonize new habitats with low genetic diversity. Such species provide an opportunity to study rapid adaptation to complex environmental conditions. METHODS: Using replicate reciprocal transplants of clones across three habitats, we described patterns of phenotypic response and assessed degree of local adaptation. KEY RESULTS: We found plants from beach habitats had decreased height, number of leaves, leaf area, and biomass allocation to roots and...

Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report the first high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a ≥10-fold increase in dust deposition during glacials and a ≤5-fold...

Collaborative Research: Do Anthropogenic Light Levels Affect Predation Mortality on Diel Vertically Migrating Mesopelagics?

Steven Murawski
In recent years, oil and gas facilities have aggressively extended into the ultra-deep waters (>1,000 m) in the Gulf of Mexico (GoM), impinging upon the offshore habitats of both large epipelagic predators and diel vertically migrating (DVM) mesopelagics. High intensity lighting at these platforms attracts a variety of prey at night including lanternfishes (Myctophidae) and other vertically migrating fishes, squids and zooplankton. As well, a number of pelagic apex predators including yellowfin tuna Thunnus albacares,...

Experimental evidence that host species composition alters host-pathogen dynamics in a ranavirus-amphibian assemblage

Paul Snyder, Chloe Ramsay, Carmen Harjoe, Emily Khazan, Cheryl Briggs, Jason Hoverman, Pieter Johnson, Daniel Preston, Jason Rohr & Andrew Blaustein
Losses in biodiversity can alter disease risk through changes in host species composition. Host species vary in pathogen susceptibility and competence. Yet how changes in diversity alter host-pathogen dynamics remains unclear in many systems, particularly with respect to generalist pathogens. Amphibians are experiencing worldwide population declines linked to generalist pathogens, such as ranavirus, and thus represent an ideal group to investigate how host species composition affects disease risk. We conducted experiments where individuals in the...

Supplementary materials for the manuscript entitled: Mitochondrial Perspective on Species Identification and Delimitation for troglobitic Cicurina (Arachnida: Araneae: Hahniidae) from Central Texas

Preston J. McDonald McDonald, Julie A. Parlos, James C. Cokendolpher, Stirling J. Robertson, Jean K. Krejca, Jennifer C. Girón & Caleb D. Phillips
Central Texas is home to a diverse fauna of endemic species found in the karst areas along the Balcones Fault Line, the Edwards Aquifer region, and associated springs. The fauna occurring in Bexar County experience especially high anthropogenic pressure due to urban sprawl and suburban development in and around San Antonio, one of the largest cities in the United States. Among local fauna are numerous troglobitic spider species of the genus Cicurina Menge, 1871 (subgenus...

Revisiting the quantity theory of money in Euro Area: the case of Greece

Serdar Ongan, Ismet Gocer & Ayse Ongan
This study revisits the Quantity Theory of Money for Greece from the perspective of potentially nonlinear relations between the variables of the equation of exchange. Therefore, this methodological approach makes this study different from previous empirical studies, which were constructed on the assumption of linear relations in this equation. To this aim, for the first time, the nonlinear ARDL model is applied for testing the QTM for a specific country. This model decomposes the variables...

Multifaceted characteristics of aridity changes and causal mechanisms in Chinese drylands

Ying Hu, Fangli Wei, Bojie Fu, Shuai Wang, Lanhui Wang & Yongzhe Chen
The water cycle is accelerating in the context of global warming. However, how the multifaceted characteristics of aridity, particularly atmospheric, hydrological, and ecological drying, change and interact with each other are largely unknown. A gap we bridged was discovering the causal relationships underlying the atmosphere-hydrosphere-biosphere nexus from the nonlinear dynamic system perspective based on convergent cross mapping (CCM). Dryland area in China has expanded since 1982, while the vegetation greenness indicated by leaf area index...

Genetic structure in patchy populations of a candidate foundation plant: a case study of Leymus chinensis using genetic and clonal diversity

Chan Zhuo, Jian Guo, Zhuo Zhang, Christina L. Richards, Kent E. Holsinger & Gordon A. Fox
PREMISE: The distribution of genetic diversity on the landscape has critical ecological and evolutionary implications. This may be especially the case on a local scale for foundation plant species since they create and define ecological communities, contributing disproportionately to ecosystem function. METHODS: We examined the distribution of genetic diversity and clones, which we defined first as unique multilocus genotypes (MLG), and then by grouping similar MLGs into multilocus lineages (MLL). We used 186 markers from...

Data from: Epigenetic potential and DNA methylation in an ongoing House Sparrow (Passer domesticus) range expansion

Haley E Hanson, Chengqi Wang, Aaron W Schrey, Andrea L Liebl, Mark Ravinet, Rays H Y Jiang & Lynn B Martin
During range expansions, organisms can use epigenetic mechanisms to adjust to conditions in novel areas by altering gene expression and enabling phenotypic plasticity. Here, we predicted that the number of CpG sites within the genome, one form of epigenetic potential, would be important for successful range expansions because DNA methylation can modulate gene expression, and consequently plasticity. We asked how the number of CpG sites and DNA methylation varied across five locations in the ~70...

Molecular systematics, species concepts and myrmecophytism in Cecropia (Cecropieae: Urticaceae): Insights from restriction-site associated DNA

Erin Treiber, Paul-Camilo Zalamea, Maria Fernanda Torres Jimenez, Santiago Madriñán & George Weiblen
Cecropia is a group of fast-growing pioneer trees that are important in forest regeneration and a common ant-plant mutualism in the Neotropics. To investigate the evolution of mutualism between Cecropia and associated ants a phylogenetic framework is necessary. Cecropia species are difficult to distinguish morphologically and conventional genetic markers are insufficiently variable to resolve phylogeny. Our study aimed to infer relationships in approximately half of the species in the genus using restriction site associated DNA...

Observational data and model output for sediment nutrient cycling at Patagonian fjords

Hong Chin Ng, Jon R. Hawkings, Jemma L. Wadham, Katharine R. Hendry, Tim M. Conway, Sebastien Bertrand, Matthias Sieber, Brent A. Summers, Felipe S. Freitas, James P.J. Ward, Helena V. Pryer & Sandra Arndt
Glacier meltwater supplies a significant amount of silicon (Si) and iron (Fe) sourced from weathered bedrock to downstream ecosystems. However, the extent to which these essential nutrients reach the ocean is regulated by the nature of the benthic cycling of dissolved Si and Fe within fjord systems, given the rapid deposition of reactive particulate fractions at fjord heads. The dataset is used to examine the benthic cycling of the two nutrients at Patagonian fjord heads...
