“…Diffusive spread is expected for pathogens with highly mobile host species (for example, migratory passerines that transport West Nile virus), while jump dispersal is expected for patchily distributed species with unequal time scales of within-and between-patch transmission (for example, livestock farms that mediated foot-and-mouth disease). Either of these patterns is consistent with the natural history of bats: cave-dwelling bats exhibit long-distance aerial migration 15 and high levels of seasonal mixing 16,17 , but bats in temperate North America are also associated with patchily distributed geologic formations, particularly karst outcrops of the Appalachian range and Interior Plateaus and Highlands 18 . How WNS should be expected to spread is, therefore, an open question.…”

Spread of white-nose syndrome on a network regulated by geography and climate

Wildlife and plant diseases can reduce biodiversity, disrupt ecosystem services and threaten human health. Emerging pathogens have displayed a variety of spatial spread patterns due to differences in host ecology, including diffusive spread from an epicentre (West Nile virus), jump dispersal on a network (foot-and-mouth disease), or a combination of these (Sudden oak death). White-nose syndrome is a highly pathogenic infectious disease of bats currently spreading across North America. Understanding how bat ecology influences this spread is crucial to management of infected and vulnerable populations. Here we show that white-nose syndrome spread is not diffusive but rather mediated by patchily distributed habitat and large-scale gradients in winter climate. Simulations predict rapid expansion and infection of most counties with caves in the contiguous United States by winter 2105-2106. Our findings show the unique pattern of white-nose syndrome spread corresponds to ecological traits of the host and suggest hypotheses for transmission mechanisms acting at the local scale.

“…Buchler (1976) noted that the 6-g Myotis lucifugus tended to select prey with body lengths of 4-9 mm. Similarly, Black (1974) found that where bat assemblages comprised species that weighed 5-10 g, insects of 6-10 mm body length were most abundant. Corynorhinus t. ingens is a relatively large vespertilionid bat (summer body mass of non-pregnant females was 10.5-15.25 g, n = 14; Wethington, 1994), and generally, arthropod remains (fecal components identifiable beyond order and culled wings on drop sheets) suggested that they preferred arthropods > 5 mm in body length.…”

“…Suction traps may overrepresent smaller insects (Taylor, 1962) and light traps may overrepresent positively phototaxic insects (Black, 1974). We chose Malaise traps to sample the arthropod fauna to avoid the above biases; however, we acknowledge that large Coleoptera and Hemiptera may have been underrepresented in our samples (Juillet, 1963;Kunz, 1988).…”

“…To determine if C. t. ingens demonstrated positive, negative, or no selection for arthropod orders, weekly relative abundances of arthropods captured in Malaise traps and found in feces (n = 13 weeks for which both data were available) were compared with Wilcoxon's signed-rank test (Sokal and Rohlf, 1981). While exceptions exist, size of a bat can determine, in part, size of prey items consumed (Ross, 1967;Black, 1974;Buchler, 1976). Buchler (1976) noted that the 6-g Myotis lucifugus tended to select prey with body lengths of 4-9 mm.…”

“…Other species are specialists, and many may be categorized as either beetle or moth strategists (Black, 1974), although such distinctions are not absolute (Fenton et al, 1977). Old World Barbastella (Rydell et al, 1996;Sierro and Arlettaz, 1997) and Plecotus (Feldman et al, 2000) tend to be moth specialists, and the latter is quite similar to Corynorhinus in taxonomy (Tumlison and Douglas, 1992; but see Bogdanowicz et al, 1998, andHoofer andVan Den Bussche, 2001) and feeding habits (Ross, 1967;Whitaker et al, 1977;Dalton et al, 1986;Sample and Whitman, 1993;Hurst and Lacki, 1997;Lacki and Ladeur, 2001).…”

Retinal connections were studied in Eptesicus fuscus and Artibeus jamaicensis using anterograde axonal degeneration and autoradiographic techniques following unilateral enucleations and uniocular injections of radioactive amino acids. Although each retina projected bilaterally to the brainstem, the number of silver grains in the emulsion of autoradiographs indicated that nearly all fibers in the optic nerve entered the contralateral optic tract. Ipsilaterally, a major portion of the projection ended in the suprachiasmatic nucleus; caudal to the suprachiasmatic nucleus, the amount of label was so small that individual silver grains were counted to determine the location and quantity of label in other ipsilateral nuclei. In both species the retinal projection terminated bilaterally in the suprachiasmatic, dorsal lateral geniculate, ventral lateral geniculate, and pretectal olivary nuclei and contralaterally in the posterior pretectal nucleus, superficial gray layers of the superior colliculus, and nuclei of the accessory optic system. In Eptesicus the projection to the nucleus of the optic tract ended contralaterally, and in Artibeus it ended in this nucleus bilaterally. The results of this study revealed a basic theme in the optic projection of the two ecologically different microchiropterans. The results differed, however, in that the projection was larger and visually related nuclei were better developed in Artibeus. Such variations are presumed to relate to eye size and the relative use of vision by the two chiropterans.
