The Ecology Of Phenology In A Changing World


Phenology is the study of the timing of recurrent biological events (or phenophases), the causes of these timings in regard to the biotic and abiotic drivers, and the connection among phases of the same or different species [ 1 ]. Plant phenology is one of the strongest indicators of ecological responses to climate change, and altered phenology can have pronounced effects on net primary production, species composition in local communities, greenhouse gas fluxes, and ecosystem processes. Metrics Shifts in phenology can impact organism fitness, ecosystem function, and goods and services from nature. Climate change management must better integrate phenology to optimize. Phenology in a Changing World. as "perhaps the simplest process to track changes in the ecology of species in response to. climate change" [23]. In light of such high profile calls. Phenology is an integrative environmental science that has achieved a prominent position in current global-change research, due to its capacity to monitor, understand and predict the timing of recurrent biological events related to climate, such as bird migration, frog calling, and leafing, flowering and fruiting of plant populations (Rosenzweig et al. Many fields of ecological research have been re-invigorated and re-analysed from the perspective of a changing climate: phenology is an exemplar of such a revitalized field (Cleland et al. In the past, phenology researchers most often simply characterized phenological schedules or calendars, or investigated how climatic variation was linked to plant or animal behaviours, such as. 21 Citations 2 Altmetric Metrics Abstract Diverse taxa have undergone phenological shifts in response to anthropogenic climate change. While such shifts generally follow predicted patterns, they. Phenology varies widely over space and time because of its sensitivity to climate. However, whether phenological variation is primarily generated by rapid organismal responses (plasticity) or. Although phenological shifts in response to climate are often assumed to benefit species' performance and viability, phenology's role in allowing population persistence and mediating species-level responses in the face of climate change remain unclear. Here, we develop a framework to understand when and why phenological shifts at three biological scales will influence performance. Phenology is a harbinger of climate change, with many species advancing flowering in response to rising temperatures. However, there is tremendous variation among species in phenological response to warming, and any phenological differences between native and non-native species may influence invasion outcomes under global warming. New perspectives and insights concern-ing the role of phenology in a changing climate are forcing a rethinking of phenology's place in ecological and evolution-ary theory and conservation practice (Forrest & Miller-Rushing, 2010). Research from Arizona presented by Crimmins et al. provides a valuable contrast with this grow-ing body of. The rejuvenation of this long-studied subdiscipline of ecology has been primarily induced by three factors: (1) phenological shifts are a ubiquitous phenomenon and can be interpreted as a sensitive indicator of the ecological impacts of climate change (Walther et al. 2002 ); (2) the consequences of phenological shifts, including the start, senes.

We define an axis of habitat loss (x) that ranges from a pristine, undisturbed stage (zero) to a stage (one) of complete disturbance where all species present in the zero stage have lost their axis may represent a reversed area axis, widely used to indirectly predict extinction rates with species-area curves (He & Hubbell. issue also emphasizes the importance of phenology in nearly all aspects of ecology and evolution. In this introduction, we start by clarifying the relationship between phenology and life history, and by briefly reviewing the physiological processes and environmental cues governing phenology in different taxa. We then move from the individual. The statement that the world's environment is facing a period of unprecedented change has become a truism. The 'anthropogenic cocktail' of climate change, habitat loss and degradation are combining to put considerable pressure on the world's ecosystems []. We know that the natural world is already being affected because we can observe effects consistent with climate change. Vegetation phenology is highly sensitive to climate change. Phenology also controls many feedbacks of vegetation to the climate system by influencing the seasonality of albedo, surface roughness length, canopy conductance, and fluxes of water, energy, CO 2 and biogenic volatile organic compounds. In this review, we first discuss the environmental drivers of phenology, and the impacts of. Plants are finely tuned to the seasonality of their environment, and shifts in the timing of plant activity (i. phenology) provide some of the most compelling evidence that species and ecosystems are being influenced by global environmental change. Researchers across disciplines have observed shifting phenology at multiple scales, including.

[PDF] Root Phenology In A Changing Climate.

Ecology Letters is a broad-scope ecology journal considering all taxa, in any biome and geographic area, and spanning community, microbial & evolutionary ecology. Abstract Shifts in plant phenology influence ecosystem structures and functions, yet how multiple global change drivers interact to affect phenology remains elusive. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing, and other areas. Like its predecessor, this second edition of Phenology is a synthesis of current phenological knowledge, designed as a primer on the field for global change and. Root phenology in a changing climate. McCormack, +2 authors. Published in Journal of Experimental… 1 June Environmental Science. It is suggested that root initiation, peak growth, and root cessation may be under different controls, whereas the timing of peak root growth may represent trade-offs. Phenology and climate. The change from a dormant winter to a biologically active spring landscape has numerous biogeochemical and biophysical effects on climate. Earlier leaf unfolding and delayed leaf fall as a result of global warming (graph) ( 3, 17) will thus affect climate change itself. Climate change causes shifts in ecosystems. Rising temperatures cause shifting ecosystems, either expanding or decreasing the geographical range of specific types of habitats, or changing the timing of seasons. For example, a study of European butterflies found that populations had shifted north by 114 km between 1990-2008 due to increasing. The discussion on the main advances on and challenges for dispersal ecology was the main motivation for the organization of a thematic topic session entitled Dispersal processes driving plant movement: challenges for understanding and predicting range shifts in a changing world at the Annual Meeting of the British Ecological Society (2015. Global climate change is recognized as a threat to species survival and the health of natural systems. Scientists worldwide are looking at the ecological and hydrological impacts resulting from climate change. Climate change will make future efforts to restore and manage wetlands more complex. Wetland systems are vulnerable to changes in quantity and quality of their water supply, and it is. Phenology is the study of timing of periodic activities in biological life cycles. It describes an inherent component of ecosystem dynamics, and shifts in biological activity have been increasingly recognized as an indicator of global change. Although phenology is mainly studied above the ground, major ecosystem processes, such as decomposition. Organisms are now displaying a number of ecological and evolutionary responses to climate change 6, which include shifts in their phenologies. As climate change leads to shifts in the phenology of. Our synthesis, covering most of the world, highlighted previously unappreciated patterns in avian phenological shifts over time, suggesting that specific life-history or ecological traits may drive different responses to climate change. Plant phenology, the timing of plant growth and development, is changing in response to global climate change. Changing temperature, soil moisture, nitrogen availability, light, and elevated CO 2 are all likely to affect plant phenology. Alteration of plant phenology by global climate change may alter the ability of plants to acquire soil resources (water and nutrients) by altering. Changes in spring phenology in boreal forests around the subarctic region have a profound impact on the global carbon and water cycles.
