Tree-ring time series provide long-term, annually resolved information on the growth of individual trees. However, public tree-ring archives contain a considerable portion of data collected from trees that have been selected with specific research questions in mind (e.g., for climate reconstruction). This makes these archives a biased representation of the sensitivity of forest ecosystems to ongoing climate variation (e.g. temperature, precipitation), including non-stationarity (i.e....
Mexico has a forest cover of 660,400 km2, representing 34% of its territory. Due to deforestation and land-use change, Mexico has lost 32,200 km2 over the last 25 years, representing 1.9% of its territory. Mexican forests are now additionally threatened by climate change. Currently, there is no assessment of the impact of current and future climatic changes on forest productivity to develop mitigation and adaptation plans in the forestry sector. Most growth studies in Mexico focus on clima...

Blue Intensity (BI) is a cost-effective analytical method for measuring relative wood density in the rings of conifer tree species. Since early concept papers in the 1990s/2000s, there has been a recent explosion in the application of this method for both dendroclimatology and historical dating as well as other dendro-disciplines. The beauty of BI is that the analytical costs, mainly related to the cost of a h...
Free, in person and onlineThe stable isotopic compositions of carbon and oxygen (d13C and d18O) measured in tree rings are valuable proxies for reconstructing paleoclimate and are increasingly used as paleophysiological proxies. Applying these proxies in ecophysiology and paleoclimate can be challenging as they rely on complex process-based models and poorly constrained input data. In recent years, h...

Africa is faced with a number of challenges including climate change and ecological disturbance due to various anthropogenic activities. These problems adversely affect the forests and also ecosystem services. My appreciation for the forests motivated me to pursure my undergraduate studies in Forestry. I first applied dendrochronology during my PhD research which focused on understanding the climate change vulnerability of the Zambezi teak forests in Zambia. However, lack of research facil...
Climate change poses an existential threat to trees, given our understanding of the importance of climate in shaping their geographic distributions. Climate envelope models are commonly used to predict how species will respond to climate change. These models give rise to the leading edge-trailing edge paradigm for range change: populations at the cool edge of a species’ distribution are expected to benefit from warming, whereas populations at the warm edge are expected to decline. We chall...
