“…Other mobility studies on Argynnis or related species report lower mean flight distances than we found, e.g. 330 meters (females) and 200 meters (males) for A. aglaja in the Czech Republic (Zimmermann et al ., 2009), 49 meters (females) and 32 meters (males) for Brenthis ino in Germany (Weyer and Schmitt 2013), and 160 meters (females) and 230 meters (males) for Boloria aquilonaris in Finland (Gorbach 2011). Interestingly, despite the majority of individuals in this study being sedentary, we found, to our knowledge, the longest recorded flight distances in the two studied species in an MRR‐study, 11.9 km for A. aglaja and 3.7 km for A. adippe .…”

Mobility may affect species' distribution patterns in heterogeneous landscapes, and it might impact fitness by influencing mating success, predation avoidance, and foraging success. Here, we studied causes and consequences of mobility patterns in butterflies: Argynnis adippe, a specialist constrained to warm microhabitats within woodland landscapes, and A. aglaja, a relative generalist that also inhabits grasslands, and tolerates lower temperatures. We explored associations of movement and occurrence patterns, population size and density, niche breadth, wing size, and different types of behaviour prior to capture by conducting a mark‐release‐recapture study on the Swedish island Öland. We marked 1 935 A. aglaja and 123 A. adippe and achieved recapture rates of 9.5% (A. aglaja), and 8.9% (A. adippe). Estimated population densities were 5 066 and 814 individuals per km2, for A. aglaja and A. adippe, respectively. Argynnis aglaja was less likely to perform long‐distance flights according to estimated dispersal kernels, hinting at negative density‐dependent dispersal in these species. Although we detected the longest flight distances ever in these species in MRR studies (11.9 km for A. aglaja and 3.7 km for A. adippe), most butterflies were recaptured within 200 meters (60–80%). Low recapture rates along with low estimated residence times and the potential for long movement might indicate that many individuals left the study area, and that the species form open populations, stretching over large areas. Despite significant differences in wing size and behaviour types, mean observed flight distances were similar in these species.

“…Using the residence rate ( Ø i ), that is, the proportion of individuals remaining in the study area between two consecutive sessions and an estimate of the number of individuals recruited in the area during the same time ( B i ), we may calculate the total abundance N total . The calculation was performed with the use of two formulas:

N_{total} goodbreak= ((), 1 goodbreak- M) normal∑ N_{i},

where M is arithmetic mean of Ø i , ∑ N i is sum of all model abundance values (Watt et al, 1977), and

N_{total} goodbreak= N_{2} goodbreak+ normal∑ B_{i},

where N 2 is model abundance for the second date, ∑ B i is total number of individuals recruited since the first date (Gorbach, 1998).…”

In this study, we tested the applicability of three common methods of absolute abundance estimation—Peterson, Bailey and Jolly‐Seber—to Ixodes persulcatus ticks based on mark‐release‐recapture data. The ticks were collected by flagging during the seasonal activity peak of the ticks in the mid‐taiga zone of Karelia (62.0697°N, 33.9614°E). In total, 108 females and 92 males of I. persulcatus were marked. The marked individuals were captured 161 times before the end of the study period with their proportion in the samples reaching 50%. Females were recaptured more often than males, 105 versus 56 times. Estimates of adult tick abundance ranged from 0.4 to 2 specimens per m2 depending on the calculation method. The obtained estimates of absolute abundance varied unpredictably depending on the length of the intervals between capture sessions and showed no significant correlations with the number of ticks collected by flagging. The choice of the method of tick abundance estimation mainly depends on the study aims. The Petersen method may be useful for quick estimates of local tick abundance, whereas the Jolly‐Seber method allows an estimation of the absolute abundance during the entire period of the tick activity. Individual marking of ticks may improve the accuracy of the estimates.
