“…We selected the dentary for this project because it is among the most common elements in the fossil record of North American Myotis (e.g., Czaplewski and Peachey 2003), and previous studies using geometric morphometrics to distinguish among dentaries of other taxa of bats have met with success (Gannon andRácz 2006, Sztencel-Jabłłonka et al 2009). We used 17 landmarks, most of which were tips of processes and the posterior margins of alveoli ( Fig.…”

“…Only five bat species in three genera (Desmodus, Dyphylla and Diaemus) are known to feed on blood (from ∼1200 known bat species), and all of them occur in the Americas. Two of these species went globally extinct during the end of the Pleistocene or early Holocene, Desmodus draculae from South America and D. stocki from North America (Pardiñas & Tonni, 2000;Czaplewski, Peachey & Ammerman, 2003).…”

Ecological and evolutionary legacy of megafauna extinctions

et al. 2017

For hundreds of millions of years, large vertebrates (megafauna) have inhabited most of the ecosystems on our planet. During the late Quaternary, notably during the Late Pleistocene and the early Holocene, Earth experienced a rapid extinction of large, terrestrial vertebrates. While much attention has been paid to understanding the causes of this massive megafauna extinction, less attention has been given to understanding the impacts of loss of megafauna on other organisms with whom they interacted. In this review, we discuss how the loss of megafauna disrupted and reshaped ecological interactions, and explore the ecological consequences of the ongoing decline of large vertebrates. Numerous late Quaternary extinct species of predators, parasites, commensals and mutualistic partners were associated with megafauna and were probably lost due to their strict dependence upon them (co-extinctions). Moreover, many extant species have megafauna-adapted traits that provided evolutionary benefits under past megafauna-rich conditions, but are now of no or limited use (anachronisms). Morphological evolution and behavioural changes allowed some of these species partially to overcome the absence of megafauna. Although the extinction of megafauna led to a number of co-extinction events, several species that likely co-evolved with megafauna established new interactions with humans and their domestic animals. Species that were highly specialized in interactions with megafauna, such as large predators, specialized parasites, and large commensalists (e.g. scavengers, dung beetles), and could not adapt to new hosts or prey were more likely to die out. Partners that were less megafauna dependent persisted because of behavioural plasticity or by shifting their dependency to humans via domestication, facilitation or pathogen spill-over, or through interactions with domestic megafauna. We argue that the ongoing extinction of the extant megafauna in the Anthropocene will catalyse another wave of co-extinctions due to the enormous diversity of key ecological interactions and functional roles provided by the megafauna.

“…It has also been suggested that climate change could result in north-westerly expansion of the vampire bat continental range from Central America to include Texas and Louisiana in North America [92], with additional potential habitats in Florida, California and Arizona [93][94][95][96] where there is fossil evidence for the existence of Desmodus bats thousands of years ago [94,96]. However, for populations to be established especially on the islands, female D. rotundus bats must also demonstrate long-range movement which appears to contradict their philopatric behaviour.…”

Movement of animals and plants from mainland populations contributes to the genetic diversity and viability of geographically isolated island biota, but also carries risks of pathogen introductions. The bat fauna of the island of Trinidad reflects species diversity on the neighbouring South American mainland and includes the common vampire bat (Desmodus rotundus). We determined relationships between Trinidad and mainland vampire bat populations and the extent of mainland-island movement by comparing the genetic structure (nuclear and mitochondrial) and morphology of the Trinidadian D. rotundus population to populations in neighbouring regions of the South American mainland and estimating evolutionary histories and patterns of gene flow. Results indicate that Trinidadian D. rotundus are genetically and morphologically distinct from mainland populations, although limited unidirectional male-biased mainland to island gene flow occurs at an estimated rate of 3.3 migrants per year. Two geographically-defined Desmodus cytochrome b clades were identified within Trinidad (i.e., one restricted to the South-Western peninsula which grouped with Venezuelan sequences and the other found throughout the rest of the island which grouped with sequences from Suriname and Guyana) suggesting long-standing female philopatry. The geographic distribution of these clades mirrors that of two previously identified geographically defined rabies virus (RABV) lineages introduced to Trinidad from the mainland. This finding suggests that bat dispersals and RABV introductions occur via both the northern and south-western island peninsulas, with subsequent male-driven intra-island viral spread enabled by bat nuclear homogeneity of these populations. These study findings will contribute to the development of contemporary evidence-based vampire bat population control and rabies prevention programs within island populations.
