Recording fine-scale movement of ground beetles by two methods: Potentials and methodological pitfalls
<p><span><span>Movement trajectories are usually recorded as a sequence of discrete movement events described by two parameters: step length (distance) and turning angle (bearing). One of the most widespread methods to record the geocoordinates of each step is by a GPS device. Such devices have limited suitability for recording fine movements of species with low dispersal ability including flightless carabid beetles at small spatio-temporal scales. As an alternative, the distance-bearing approach can avoid the measurement error of GPS units since it uses directly measured distances and compass azimuths. As no quantification of measurement error between distance-bearing and GPS approaches exists so far, we generated artificial fine-scale trajectories and in addition radio-tracked living carabids in a temperate forest and recorded each movement step by both methods. Trajectories obtained from distance-bearing were compared to those obtained by a GPS device in terms of movement parameters. Consequently, both types of trajectories were segmented by state-switching modeling into two distinct movement stages typical for carabids: random walk and directed movement. We found that the measurement error of GPS compared to distance-bearing was 1.878 m (SEM = 0.181 m) for distances and 31.330° (SEM = 2.066°) for bearings. Moreover, these errors increased under dense forest canopy and rainy weather. Distance error did not change with increasing distance recorded by distance-bearing but bearings were significantly more sensitive to error at short distances. State-switching models showed only slight, not significant, differences in movement states between the two methods in favor of the random walk in the distance-bearing approach. However, the shape of the GPS-measured trajectories considerably differed from those recorded by distance-bearing caused especially by bearing error at short distances. Our study showed that distance-bearing could be more appropriate for recording movement steps not only of ground-dwelling beetles but also other small animals at fine spatio-temporal scales.</span></span></p>
Combining biogeographic approaches to advance invasion ecology and methodology
<p>1) Understanding the causes of plant invasions requires that parallel field studies are conducted in the native and introduced ranges to elucidate how biogeographic shifts alter the individual performance, population success, and community-level impacts of invading plants. Three primary methods deployed in in situ biogeographic studies are directed surveys, where researchers seek out populations of target species, randomized surveys, and field experiments. Despite the importance of these approaches for advancing biogeographic research, their relative merits have not been evaluated.</p> <p>2) We concurrently deployed directed surveys, randomized surveys, and in situ field experiments for studying six grassland plant species in the native and introduced ranges. Metrics included plant size, fecundity, recruitment, abundance, and invader impact, as well as soil properties and root associations with putative fungal mutualists and pathogens.</p> <p>3) Consistent with key invasion hypotheses, Bromus tectorum experienced increased size and fecundity in the introduced range linked to population increases and significant invader impacts, along with altered fungal associations. However, performance differences did not predict population increases and invader impacts across species. Rather, the differential effect of disturbance in facilitating greater recruitment in the introduced range appeared to play a crucial, though previously underexplored, role in driving invader success.</p> <p>4) Directed surveys consistently generated information on plant performance and fungal associations. However, soil sampling suggested that directed surveys may have been biased toward disturbed conditions for half the species. Randomized surveys generated robust data for population comparisons and impact, but generally failed to produce performance metrics for species that were uncommon or flowered outside the peak sampling window. Field experiments controlled for bias and confounding factors and provided rare information on recruitment and disturbance effects, but scant recruitment in the native range and ethical constraints on growing invaders in the introduced range limited information on performance and plant-fungal interactions.</p> <p>5) Synthesis. Each method had strengths and weaknesses. However, when combined they provided complementary information to paint the most complete biogeographic picture to date for several introduced plants. We propose a hybrid approach to optimize biogeographic studies.</p>

Figure 2. A paired box plot for comparing fresh weight (gram) of final instar Graptopsaltria nigrofuscata nymphs between the beginning (16-Apr, Blue) and the end (6 Jul, Red) of the mesocosm experiment. Two points of 16 Apr data with no line connected to 6 Jul are fresh weight of cicada nymphs that died until the end of experiment. Paired t-test indicated a significant increase in fresh weight of the nymphs from April to July (t = -2.8334, df = 5, p-value = 0.037).
