Exploitation of Insects around Streetlamps by Bats in Sweden
1. Nine species of insectivorous bats in southern Sweden were monitored with a bat detector to assess which species regularly forage around streetlamps and which do not. Only the fast-flying speciesExpand
Foraging Strategy and Predation Risk as Factors Influencing Emergence Time in Echolocating Bats
TLDR
The evening emergence time among echolocating bats appears to be a function of dietary specializations and foraging strategy, and is probably also affected by the ability to avoid predation. Expand
Timing of foraging flights of three species of bats in relation to insect activity and predation risk
TLDR
Protective tree cover may allow earlier evening emergence of bats and therefore provide access to more food, and have implications for the conservation ofbats and their habitats particularly at high latitudes. Expand
Use of lamplit roads by foraging bats in southern England
TLDR
The mean number of bat passes recorded in any 1-km section of road was positively correlated to the number of white streetlamps along the section, and also, independently, to the amount of trees and hedgerows. Expand
Bat Mortality at Wind Turbines in Northwestern Europe
We reviewed published and unpublished written reports on bat mortality at wind farms in northwestern Europe. The estimated number of bats killed per turbine annually was relatively low (0–3) on flat,Expand
Signal strength, timing, and self-deafening: the evolution of echolocation in bats
TLDR
It is proposed that the ancestors of bats were small, nocturnal, sylvatic gliders that used echolocation for general orientation and used echo- location to detect, track, and assess flying insects, which they attacked while gliding. Expand
Functional significance of emergence timing in bats
TLDR
The results largely corroborate the hypothesis that emergence time, and therefore feeding performance, of insectivorous bats is constrained at bright light conditions, possibly by predation risk (from birds), and modified by energetic considerations. Expand
Mortality of bats at wind turbines links to nocturnal insect migration?
This note is based on a literature search and a recent review of bat mortality data from wind farms in Europe (published elsewhere). We suggest that mortality of bats at wind turbines may be linkedExpand
Emergence, Echolocation, Diet and Foraging Behavior of Molossus ater (Chiroptera: Molossidae)1
TLDR
Calculations concerning the costs of flight and roosting show that they were more than covered by the energy intake the bats achieved, and energy was not limiting for these bats at the time of the authors' study. Expand
Echolocation constraints of Daubenton’s Bat foraging over water
TLDR
Daubenton’s Bat operates at very low signal-to-noise ratios when foraging for insects near the water surface, suggesting that bats generally avoid foraging low over turbulent water. Expand
