“…The observed records of the SSN periodicities from growth rings of trees from places with different climates, from satellites and 10 Be concentration in polar ice show regular mean cycles near 6, 11, 22, 52 and 90 years in different time scales [2,19,20,24,33,38,46,47,51,52,63]. These fluctuations are present in centurial and decadal time scales [36].…”

-A tree ring width chronology developed from 58 samples taken from Chinese pine trees (Pinus tabulaeformis Carr.) growing in Shenyang city was studied to analyze the effects of solar activity, Global Surface Air Temperature Anomalies (GSATA) and the Pacific Decadal Oscillation (PDO) on annual radial growth. An excellent response of tree rings to solar activity and global environmental change was revealed, indicating that these urban Chinese pine trees are a suitable proxy for Sun-Earth system research despite their location in Shenyang, an industrial city. The information derived from annual growth rings of urban Chinese pine trees coincides with records from undisturbed trees in a natural location, and demonstrates significant synchronous response to solar activity in the periodic bands of 5-8, 10-12 and 20-30 years. The wave signal of tree growth was also affected and amplified by the combined effect of the PDO from 1900 to 2004 and GSATA from 1880 to 2004 with a short lag time, revealing 5-8, 11-13, and 20-23 year oscillatory modes. At 20-30 year timescale, Chinese pines validated the strong GSATA influence signal at 20.8 years, and may be the primary cause of the 20 and 23 year periodic waves of tree rings. Shenyang urban tree ring growth also showed high frequency variation (2-4 y) that may be due to low periodicity of solar activity, GSATA, PDO and local climate variations, especially in the 2-4 years band width.urban tree rings / sunspot number / Pacific decadal oscillation / global surface air temperature anomaly / wavelet analysis

“…Ulric Rudenschöld (1704-1765) compared pine trees in northern and southern Finland finding both differences and similarities, which he attributed to regional climate and soil conditions (Rudenschöld, 1899). Although dendroclimatology has strong traditions in the Nordic countries, it was the American astronomer Andrew Ellicott Douglass (1867Douglass ( -1962, who in the beginning of the 20th century established a statistically valid relationship between climate and tree-ring widths (Douglass, 1909(Douglass, , 1919. He set out to investigate the influence of sunspots on precipitation in America and chose tree-rings as a suitable drought indicator.…”

Abstract. Fennoscandia has a strong tradition in dendrochronology, and its large tracts of boreal forest make the region well suited for the development of tree-ring chronologies that extend back several thousands of years. Two of the world's longest continuous (most tree-ring chronologies are annually resolved) tree-ring width chronologies are found in northern Fennoscandia, with records from Torneträsk and Finnish Lapland covering the last ca. 7500 yr. In addition, several chronologies between coastal Norway and the interior of Finland extend back several centuries. Tree-ring data from Fennoscandia have provided important information on regional climate variability during the mid to late Holocene and have played major roles in the reconstruction of hemispheric and global temperatures. Tree-ring data from the region have also been used to reconstruct large-scale atmospheric circulation patterns, regional precipitation and drought. Such information is imperative when trying to reach better understanding of natural climate change and variability and its forcing mechanisms, and placing recent climate change within a long-term context.

“…In addition, enhancements of other paleoecological methods such as dendrochronology (the dating and studying of annual growth layers in wood) and the analysis of plant macro-remains contributed significantly to the development of historical biogeography. After initial studies by Douglass (1919), dendrochronology has evolved into the most accurate dating technique within the time frame of the past 10,000 years and has expanded to be applied to the dating of archeological ruins, climate change, fire history, insect outbreaks, volcanic eruptions, and glacier movements (Schweingruber 1996;Fritts 2001;Speer 2010).…”

Biogeography is, in essence, the geography of nature or more specifically, the study of the distribution of Earth's life forms at all spatial and temporal scales. This paper traces the historical development of biogeography from ancient times to the twenty-first century, highlights contemporary trends and expansions, and previews future prospects. The cumulative discovery of biogeographic patterns culminated in the development of the theory of evolution -biogeography's greatest contribution to science. The paradigm shift to causal approaches in the early twentieth century led to ecological biogeography emerging as the second pillar of biogeography in addition to historical biogeography. Fostered by the acceptance of plate tectonics, the equilibrium theory of island biogeography, the rapid advancement of new perspectives and methods in historical biogeography, and revolutionary advances in compiling, visualizing, and analyzing spatially explicit information, biogeography evolved into a rigorous science during the second half of the twentieth century. Currently, major active sub-fields are phylogeography, macroecology, and conservation biogeography. Biogeography is on the way to becoming a 'big science', entering an era of increasingly integrative and multi-faceted approaches, increasingly accessible and available data, tools, and techniques, and interdisciplinary collaboration.
