Sensitivity of northern red oak (Quercus rubra L.) to variation of temperature and moisture availability along latitudinal and longitudinal climate gradients
… change in response to global climatic warming. Climate-growth response algorithms in forest simulation models that represent the influence of climate on tree growth are based on the geographic range limits of a species. These models assume that temperature limitations control the latitudinal …

Rhizobia diversity and their effect on the distribution of indigenous legumes in the Cape Floristic Region
… of edaphic and topographical variations, local climate gradients and frequent fires is undoubtedly important in promoting species diversity in the region. The family Fabaceae is the second largest family to Asteraceae in the CFR. It is currently comprised of about 760 species, in 37 genera …

Climatic and geodynamic influences on ocean island geomorphology
With homogeneous bedrock, dramatic rainfall gradients, and remnant surfaces that constrain their age, initial topography, and vertical motions relative to sea level, volcanic ocean islands provide an exceptional natural experiment in landscape evolution. Analyses traversing gradients in island …

Environmental correlates and associations of tuart (Eucalyptus gomphocephala) decline
… (soil type, geology, topography, and geography), climate (gradients and change), hydrology (depth, depth change, and chemistry), fire regimes, pollution and anthropogenic disturbance (fragmentation and site disturbance). Assessment of canopy condition indicates that most the Tuart distribution has …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
As climate change exacerbates forest mortality, subsequent tree regeneration depends on the presence of functional traits that allow seedlings to survive selective pressures from altered climate regimes. Many widely-distributed plant species exhibit intraspecific trait variation reflecting …

Base Flow Recession Analysis for Streamflow and Spring Flow
… characteristics of transition flow across the climate gradients are also tested in 40 watersheds. It is found that climate, which is represented by climate aridity index, is the dominant controlling factor on transition flows from early to late recession stages. Transition flows and long-term …

Temporal information partitioning networks to infer ecohydrologic behaviors
… to understand ecohydrologic systems across climate gradients based on flux tower and weather station observations. In the TIPNet framework, nodes in the network are time-series variables, and links are information theoretic measures that quantify multivariate lagged time-dependencies from …

Patterns in the composition and distribution of the vertebrate fauna, desert uplands bioregion, Queensland
… information regarding its native biota. Its climate is semi-arid and the vegetation consists predominantly of Acacia and Eucalypt woodlands, ephemeral lake habitats and grasslands. Of the original 6.8 million hectares of vegetation cover in the Desert Uplands, by 1999 over 900,000 hectares, …

The interaction of climate, tectonics, and topography in the Olympic Mountains of Washington State: the influence of erosion on tectonic steady-state and the synthesis of the alpine glacial history
The interaction of climate, tectonics, and topography in the Olympic Mountains of Washington State is explored to determine the influence of glaciers on spatially variable erosion and rock uplift rates. As glaciers have long been present on the peninsula, could glacial erosion explain the observed …
