Ecological Correlates of Ghost Lineages in Ruminants
Paleobiology, 38(1), 2012, pp. 101–111 Ecological correlates of ghost lineages in ruminants Juan L. Cantalapiedra, Manuel Herna´ndez Ferna´ndez, Gema M. Alcalde, Beatriz Azanza, Daniel DeMiguel, and Jorge Morales Abstract.—Integration between phylogenetic systematics and paleontological data has proved to be an effective method for identifying periods that lack fossil evidence in the evolutionary history of clades. In this study we aim to analyze whether there is any correlation between various ecomorphological variables and the duration of these underrepresented portions of lineages, which we call ghost lineages for simplicity, in ruminants. Analyses within phylogenetic (Generalized Estimating Equations) and non-phylogenetic (ANOVAs and Pearson correlations) frameworks were performed on the whole phylogeny of this suborder of Cetartiodactyla (Mammalia). This is the first time ghost lineages are focused in this way. To test the robustness of our data, we compared the magnitude of ghost lineages among different continents and among phylogenies pruned at different ages (4, 8, 12, 16, and 20 Ma). Differences in mean ghost lineage were not significantly related to either geographic or temporal factors. Our results indicate that the proportion of the known fossil record in ruminants appears to be influenced by the preservation potential of the bone remains in different environments. Furthermore, large geographical ranges of species increase the likelihood of preservation. Juan L. Cantalapiedra, Gema Alcalde, and Jorge Morales.

Monitoring climate change and habitat loss alone is insufficient if we are to understand the effects of these factors on complex biological communities. It is therefore important to identify bioindicator taxa that show measurable responses to climate change and habitat loss and that reflect wider-scale impacts on the biota of interest. We argue that bats have enormous potential as bioindi- cators: they show taxonomic stability, trends in their populations can be monitored, short- and long- term effects on populations can be measured and they are distributed widely around the globe. Because insectivorous bats occupy high trophic levels, they are sensitive to accumulations of pesti- cides and other toxins, and changes in their abundance may reflect changes in populations of arthro- pod prey species. -

For mammals, the patterns of diversification of Mesoamerican taxa still are controversial. Reasons for this include the region’s complex geologic history, and the relatively recent timing of such geological events. -
