Evolutionary Taxonomy

This introductory chapter provides an overview of systematics, which is the science of biological classification. It embodies the study of organic diversity and provides the comparative framework to study the historical aspects of the evolutionary process. The chapter then explores the nature of systematics as an independent discipline and briefly surveys the literature sources most frequently used by systematists. It differentiates between evolutionary taxonomy, phenetics, and phylogenetics (cladistics). Ultimately, systematics is the most strongly comparative of all of the biological sciences, and its methods and principles transcend the differences between botany and zoology. It is also the most strongly historical field within biology, and as such provides the basis for nearly all inferences concerning historical patterns and processes. Among the earth sciences, systematics is directly comparable to historical geology, and indeed the two fields find integration in paleontology.

<p>We increasingly recognize the diversity of biological systems, in terms of taxonomy, phylogeny and function, as well as the importance of biotic interactions in shaping them. However, the diversity of abiotic factors and interactions between biotic and abiotic diversity are still understudied, despite of Alexander from Humboldt’s advocacy over 200 years ago (Schrodt et al. 2019a). As such, we have lost sight of one of fundamental concepts of Biogeosciences: holistic integrative studies of patterns and processes across the Earth’s spheres.</p><p>In the face of accelerated anthropogenic and natural change of biotic and abiotic aspects, appreciation of the interaction diversity between all spheres of the Earth is urgently needed. Yet, to date, the vast majority of studies only account for the effect of climate and, potentially, soils on biodiversity, ignoring interactions (e.g. the effect of biodiversity on soils) and other aspects of geodiversity (the range, value and dynamics of geological, geomorphological, pedological and hydrological aspects and features of the Earth’s surface and subsurface). This applies to both, primary science and the science-policy interface.</p><p>I will give a brief introduction on the state-of-the-art in geodiversity – biodiversity interaction research, discuss the importance of incorporating the diversity of abiotic factors in biodiversity and conservation studies and indicate promising avenues for further research. This includes theoretical advancements, such as the recently introduced Essential Geodiversity Variables framework (Schrodt et al. 2019b), as well as practical matters, including remote sensing (Lausch et al. 2019) and modelling approaches suitable for expanding the geo- biodiversity interaction approach across the relevant spatial and temporal scales.</p><p> </p><p>F Schrodt et al.

Coastal Louisiana

Coastal Louisiana hosts 37% of the coastal wetland area in the conterminous US, including one of the deltaic coastal regions more susceptible to the synergy of human and natural impacts causing wetland loss. As a result of the construction of flood protection infrastructure, dredging of channels across wetlands for oil/gas exploration and maritime transport activities, coastal Louisiana has lost approximately 4900 km2 of wetland area since the early 1930s. Despite the economic relevance of both wetland biomass and net primary productivity (NPP) as ecosystem services, there is a lack of vegetation simulation models to forecast the trends of those functional attributes at the landscape level as hydrological restoration projects are implemented. Here, we review the availability of peer-reviewed biomass and NPP wetland data (below and aboveground) published during the period 1976–2015 for use in the development, calibration and validation of high spatial resolution (<200 m × 200 m) vegetation process-based ecological models. We discuss and list the knowledge gaps for those species that represent vegetation community associations of ecological importance, including the long-term research issues associated to limited number of paired belowground biomass and productivity studies across hydrological basins currently undergoing different freshwater diversions management regimes and hydrological restoration priorities.
