© 2017 Eller, Skálová, Caplan, Bhattarai, Burger, Cronin, Guo, Guo, Hazelton, Kettenring, Lambertini, McCormick, Meyerson, Mozdzer, Pyšek, Sorrell, Whigham and Brix. Phragmites australis is a cosmopolitan grass and often the dominant species in the ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P. australis has an extensive ecological amplitude and a great capacity to acclimate to adverse environmental conditions; it can therefore offer valuable insights into plant responses to global change. Here we review the ecology and ecophysiology of prominent P. australis lineages and their responses to multiple forms of global change. Key findings of our review …

© 2017, The Author(s). Zooxanthellate corals are threatened by climate change but may be able to escape increasing temperatures by colonizing higher latitudes. To determine the effect of host range expansion on symbiont genetic diversity, we examined genetic variation among populations of Symbiodinium psygmophilum associated with Oculina patagonica, a range-expanding coral that acquires its symbionts through horizontal transmission. We optimized five microsatellite primer pairs for S. psygmophilum and tested them on Oculina spp. samples from the western North Atlantic and the Mediterranean. We then used them to compare symbiont genotype diversity between an Iberian core and an expansion front population …
Fire Exclusion And Climate Change Interact To Affect Long-Term Changes In The Functional Composition Of Plant Communities, Daijiang Li, Donald M. Waller

© 2017 John Wiley & Sons Ltd Aim: Plant functional traits allow us to mechanistically link changes in species composition to changes in ecosystem functions. Understanding how and why changes occur in functional composition of plant communities can thus help us better conserve and restore biodiversity. We aim to examine long-term effects of fire exclusion and climate change on the functional composition of fire-maintained pine barrens in central Wisconsin. Location: Central Wisconsin, USA. Methods: Using a database that included vegetation data of surveys (1958) and resurveys (2012) of 30 sites, we quantified functional composition (α and β functional diversity, community-weighted …

© 2016 The Authors. Functional Ecology © 2016 British Ecological Society Organisms may respond to changing environments through phenotypic plasticity or adaptive evolution. These two processes are not mutually exclusive and may either dampen or strengthen each other's effects, depending on the genetic correlation between trait values and the slopes of their norms of reaction. To examine the effect of adaptation to heat stress on the plasticity of heat tolerance, we hybridized populations of the crustacean Tigriopus californicus that show divergent phenotypes for heat tolerance. We then selected for increased heat tolerance in hybrids and measured heat tolerance and the …

Quaternary River Erosion, Provenance, And Climate Variability In The Nw Himalaya And Vietnam, Tara Nicole Jonell
LSU Doctoral Dissertations
The influence of Quaternary climate variation on sediment generation, storage, and transport in two mountainous Asian river basin was examined in the largest tributary to the upper Indus River in the Himalayan rain shadow, the Zanskar River basin (~15,000 km2), and the smaller, subtropical Song Gianh basin (<3,500 km2) of central Vietnam. Spatial patterns of erosion in the Zanskar River Basin were established to quantify the dominant controls on Quaternary sedimentation in the Himalayan rain shadow on the edge of the Tibetan Plateau. Glacial erosion and precipitation along the High Himalaya together dominate sediment production and transport …
