“…Existing dendroclimatological results are limited to the native Iceland tree species, Betula pubescens and Sorbus aucuparia, from relatively isolated areas. Constructed tree ring chronologies show spring and summer temperature signals, with the maximum length of the records being approximately 130 years [28,29,[65][66][67]. Other studies used dendrochronology for dating geomorphological processes [68], driftwood [69], and volcano eruption [70].…”

Climatic Signals on Growth Ring Variation in Salix herbacea: Comparing Two Contrasting Sites in Iceland

2022

Salix herbacea, being such an adaptive species, has never been studied for its climatic response. The main purpose of this study is to examine the dendrochronological potential of S. herbacea. Furthermore, it aims to identify the main environmental factors that are influencing its growth. We selected two sampling sites that are different in terms of morphology and climate. Overall, 40 samples of dwarf willow were collected from two research sites and were analyzed by following the standard dendrochronological methods. The ring width chronology of the dwarf willow from the Afrétt site spans 1953–2017, i.e., 64 years. The correlations between air temperature and the ring width of dwarf willow indicate that this species responds positively to spring and summer temperatures for the Myrdal site. For the Afrétt site, this species responds positively to winter and summer precipitation. These effects may be related to tundra browning, a process that has appeared since the beginning of the 21st century. Our work is the first attempt to create a growth ring chronology of S. herbacea and to investigate its climate sensitivity. Despite the differences in local climate in both sites, this species shows its potentiality and a direct imprint of recent environmental changes in its ring width growth pattern.

“…For instance, the assessment of long-lived fish, bivalve and coral species can reveal autumnal and even winter signals at high temporal resolution (Black et al 2016). Such data might be particularly valuable for supplementing insights from terrestrial archives to draw a more complete picture of biological and ecological responses throughout the year (Piermattei et al 2017).…”

Changes in autumnal climate affecting ecosphere diversity and productivity are arguably as important as those during other seasons, which tend to be more closely studied. Motivated by recent calls for more research on the biological and ecological consequences of seasonal climate change, we present 3 examples of innovative biogeoscience, employing novel data sets and methodologies, which refine our ability to monitor the physiological functioning and ecosystem per formance during autumn. Drawn from recent research in wildlife biology (big-game hunting), wood anatomy (tree-ring formation) and mycology (fruit-body picking), these studies provide original insights that contribute to an improved understanding of how varying environmental and climatic conditions in autumn impact the phenology, productivity and diversity of different organisms.

“…These studies indicate that growth-increment width chronologies respond to different environmental variables among species and sites. Although temperature and availability of food are among the most important [14], the seasonality of this sensitivity can vary [37,38]. This information highlights the potential diversity of climate drivers on biology and also opens the possibility for multi-proxy reconstructions.…”

A network of bivalve chronologies from semi-enclosed seas

et al. 2019

Four chronologies of the bivalve species Glycymeris pilosa have been constructed along a 300 km gradient of the eastern coastal Adriatic Sea, all of which span the common period of 1982–2015. The chronologies are compared to local and remote environmental drivers suspected to influence the biology of the system, including air and seawater temperature, precipitation and freshwater discharge. The Adriatic-Ionian Bimodal Oscillating System (BiOS), a key oceanographic feature quantified by satellite-derived absolute dynamic topography, is also compared to the chronologies. The chronologies at the two southern sites are more strongly influenced by local river discharge, while the two northern chronologies are more strongly influenced by BiOS. These results highlight the broadscale importance of BiOS to the Adriatic system as well as the heterogeneity of nearshore environmental and drivers of growth. These G . pilosa chronologies provide unique multidecadal, continuous, biological time series to better understand the ecology and fine-scale variability of the Adriatic with potential for other shallow, semi-enclosed seas.
