| mosquito consumption by insectivorous bats: does size matter? | insectivorous bats have often been touted as biological control for mosquito populations. however, mosquitoes generally represent only a small proportion of bat diet. given the small size of mosquitoes, restrictions imposed on prey detectability by low frequency echolocation, and variable field metabolic rates (fmr), mosquitoes may not be available to or profitable for all bats. this study investigated whether consumption of mosquitoes was influenced by bat size, which is negatively correlated w ... | 2013 | 24130851 |
| interspecific differences and commonalities in maternity roosting by tree cavity-roosting bats over a maternity season in a timber production landscape. | understanding maternity roost requirements is fundamental to guide timber production forest management given such roosts are vital to sustain bat populations. we tracked lactating females of three tree cavity-roosting species: gould's long-eared bat (nyctophilus gouldi) (n = 7), eastern broad-nosed bat (scotorepens orion) (n = 6) and little forest bat (vespadelus vulturnus) (n = 25), over five weeks in young (predominately <5 years old) forest regenerating from heavy timber harvest in southeast ... | 2018 | 29543883 |
| torpor and thermal energetics in a tiny australian vespertilionid, the little forest bat (vespadelus vulturnus). | data on thermal energetics for vespertilionid bats are under-represented in the literature relative to their abundance, as are data for bats of very small body mass. therefore, we studied torpor use and thermal energetics in one of the smallest (4 g) australian vespertilionids, vespadelus vulturnus. we used open-flow respirometry to quantify temporal patterns of torpor use, upper and lower critical temperatures (t (uc) and t (lc)) of the thermoneutral zone (tnz), basal metabolic rate (bmr), rest ... | 2005 | 16088391 |
| foraging ranges of insectivorous bats shift relative to changes in mosquito abundance. | the need to develop effective management strategies for insectivorous bat populations requires an understanding of factors influencing habitat use. availability of pest prey, such as mosquitoes is likely to be one such factor. to assess whether this is the case, we radio-tracked vespadelus vulturnus thomas (little forest bat), a predator of aedes vigilax skuse (saltmarsh mosquito), in saltmarsh and adjacent coastal swamp forest during periods of high and low ae. vigilax abundance. when mosquito ... | 2013 | 23667699 |
