| high-amplitude fluctuations and alternative dynamical states of midges in lake myvatn. | complex dynamics are often shown by simple ecological models and have been clearly demonstrated in laboratory and natural systems. yet many classes of theoretically possible dynamics are still poorly documented in nature. here we study long-term time-series data of a midge, tanytarsus gracilentus (diptera: chironomidae), in lake myvatn, iceland. the midge undergoes density fluctuations of almost six orders of magnitude. rather than regular cycles, however, these fluctuations have irregular perio ... | 2008 | 18322533 |
| deciphering diet and monitoring movement: multiple stable isotope analysis of the viking age settlement at hofstaðir, lake mývatn, iceland. | a previous multi-isotope study of archaeological faunal samples from skútustaðir, an early viking age settlement on the southern shores of lake mývatn in north-east iceland, demonstrated that there are clear differences in δ(34)s stable isotope values between animals deriving their dietary protein from terrestrial, freshwater, and marine reservoirs. the aim of this study was to use this information to more accurately determine the diet of humans excavated from a nearby late viking age churchyard ... | 2016 | 26799531 |
