Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such far exceeds what might be produced by sampling error alone. One possible explanation for results differences researchers the decisions they make regarding statistical analyses. A growing array has explored this analytical variability different fields found substantial despite analysts having same data research question. Many these have been social sciences, but one small "many...
Intensification of the global hydrological cycle, ranging from larger individual precipitation events to more extreme multiyear droughts, has potential cause widespread alterations in ecosystem structure and function. With evidence that incidence years (defined statistically historical records) is increasing, there a clear need identify ecosystems are most vulnerable these changes understand why some sensitive extremes than others. To date, opportunistic studies naturally occurring years,...
Abstract Plant traits can be used to predict ecosystem responses environmental change using a response–effect trait framework. To do this, appropriate must identified that explain species' influence on function (“effect traits”) and the response of those species (“response traits”). Response are often measured along gradients in plant resources, such as water availability; however, precipitation explains very little variation most globally. Given strong relationship between functions, net...
During the 1930s Dust Bowl drought in central United States, species with C3 photosynthetic pathway expanded throughout C4-dominated grasslands. This widespread increase grasses during a decade of low rainfall and high temperatures is inconsistent well-known traits vs. C4 pathways. Indeed, water use efficiency generally lower, photosynthesis more sensitive to than species, consistent predominant distribution grasslands cooler environments at higher latitudes globally. We experimentally...
Tree mortality events driven by drought and warmer temperature, often amplified pests pathogens, are emerging as one of the predominant climate change impacts on plants. Understanding predicting widespread tree in future is vital they affect ecosystem goods services provided forests woodlands, including carbon storage needed to help offset warming. Additionally, if extensive enough, die-off can influence not only local but also vegetation elsewhere via teleconnections. Consequently, recent...
Abstract Experiments are widely used in ecology, particularly for assessing global change impacts on ecosystem function. However, results from experiments often inconsistent with observations made under natural conditions, suggesting the need rigorous comparisons of experimental and observational studies. We conducted such a “reality check” grassland by compiling nine independently climate experiments. Each experiment manipulated growing season precipitation ( GSP ) measured responses...
Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) among world's most endangered carnivores. The South China tigris amoyensis) critically subspecies considered functionally extinct in wild. government of has expressed its intent to reintroduce small population tigers into portion their historic range as part larger goal recover wild populations China. This would be first major reintroduction program. A...
Abstract Aim The rate and magnitude of climate‐induced tree range shifts may be influenced by range‐wide variation in recruitment, which acts as a bottleneck dynamics. Here, we compare predictions made using standard species distribution models (SDMs) an integrated metamodelling approach that assimilates data on adult occurrence, seedling recruitment dynamics, survival under both current future climate, evaluate the degree to information provided can improve Location interior west region...
Abstract Tree die-off, driven by extreme drought and exacerbated a warming climate, is occurring rapidly across every wooded continent—threatening carbon sinks other ecosystem services provided forests woodlands. Forecasting the spatial patterns of tree die-off in response to priority for management conservation forested ecosystems under projected future hotter drier climates. Several thresholds derived from drought-metrics have been proposed predict mortality Pinus edulis, model species...
Abstract Recent observational studies report weak or flat temperature − growth relationships for many tree species in temperate forests. In contrast, distribution limits of trees are strongly shaped by temperature, and show marked short‐term effects on leaf‐level ecophysiology. To better determine the warming trees, we planted one‐year‐old seedlings one lower montane (ponderosa pine), two upper (quaking aspen lodgepole subalpine (subalpine fir) situ experimental gardens an elevation gradient...
Ecologists are improving predictive capability using near-term ecological forecasts, in which predictions made iteratively and publically to increase transparency, rate of learning, maximize utility. Ongoing forecasting efforts focus mostly on long-term datasets continuous variables, such as CO2 fluxes, or more abrupt phenological events algal blooms. Generally lacking from these is the integration short-term, opportunistic data concurrent with developing climate extremes drought. We posit...
