ABSTRACT

Geobiota are defined by taxic assemblages (i.e., biota) and their defining abiotic breaks, which are mapped in cross-section to reveal past and future biotic boundaries. We term this conceptual approach Temporal Geobiotic Mapping (TGM) and offer it as a conceptual approach for biogeography. TGM is based on geological cross-sectioning, which creates maps based on the distribution of biota and known abiotic factors that drive their distribution, such as climate, topography, soil chemistry and underlying geology. However, the availability of abiotic data is limited for many areas. Unlike other approaches, TGM can be used when there is minimal data available. In order to demonstrate TGM, we use the well-known area in the Blue Mountains, New South Wales (NSW), south-eastern Australia and show how surface processes such as weathering and erosion affect the future distribution of a Moist Basalt Forest taxic assemblage. Biotic areas are best represented visually as maps, which can show transgressions and regressions of biota and abiota over time. Using such maps, a biogeographer can directly compare animal and plant distributions with features in the abiotic environment and may identify significant geographical barriers or pathways that explain biotic distributions.

ABSTRACT

Saving our science from ourselves: the plight of biological classification. Biological classification ( nomenclature, taxonomy, and systematics) is being sold short. The desire for new technologies, faster and cheaper taxonomic descriptions, identifications, and revisions is symptomatic of a lack of appreciation and understanding of classification. The problem of gadget-driven science, a lack of best practice and the inability to accept classification as a descriptive and empirical science are discussed. The worst cases scenario is a future in which classifications are purely artificial and uninformative.


Salvando a nossa ciência de nós mesmos: a saga da classificação biológica. A classificação biológica (nomenclatura, taxonomia e sistemática) está sendo subestimada. O desejo por tecnologias novas e por descrições taxonômicas, identificações e revisões mais rápidas e baratas, é sintomático da falta de apreciação e entendimento sobre a ciência da classificação. O problema de uma ciência dirigida por máquinas, a ausência da 'melhor prática', e a inabilidade de se aceitar a classificação biológica como uma ciência descritiva e empírica são discutidos. O cenário mais pessimista é um futuro no qual as classificações serão inteiramente artificiais e não-informativas.
