Foraging Cape gannets
<p>This dataset provides the positions in space and time of Cape gannets (<em>Morus capensis</em>, Lichtenstein 1823) with their associated activities (flying, sitting on the water, diving) and associations with conspecifics. It supports the analyses of a paper published in Methods in Ecology and Evolution entitled ""m2b" package in R: deriving multiple variables from movement data to predict behavioural states with random forests." by Andréa Thiebault, Laurent Dubroca, Ralf Mullers, Yann Tremblay and Pierre Pistorius, together with the methods of the R package "m2b" (<a href="https://cran.r-project.org/package=m2b">https://cran.r-project.org/package=m2b</a>).</p> <p>The data_gannets.csv file is csv (comma separated value) files with a header. The variables are</p> <p>x : longitude</p> <p>y : latitude</p> <p>t : time in year-month-day hour:minutes:second format</p> <p>b: behaviour (1, 2 ,3 for "diving", "sitting on the water", "flying" respectively)</p> <p>g : presence (1) or absence (0) of conspecific in the vicinity of the individual</p> <p>id: unique id for each individual.</p> <p><br> </p> <p>More information about data collection and processing:</p> <p>The birds were equipped on Bird Island (Algoa Bay, South Africa, under a permit from SANParks) with GPS devices (i-GotU GT-600, Mobile Action Technology Inc., Taipei, Taiwan) to record the movement path and video cameras (Camsports nano, CamsportsTM, Estrablin, France) to observe the behaviour and surroundings of the animal while at sea.</p> <p>The GPS loggers were set to record a geographical position every five seconds when the animal moved faster than 10km.h<sup>-1</sup> and every 10 or 30 seconds otherwise. The raw tracking data were interpolated using a Bézier curve to obtain a track with regular step durations of 5 s (Tremblay <em>et al.</em> 2006).</p> <p>The video footage were observed frame by frame using a video reader in Matlab software and the events of interest were visually flagged using a purpose-built video event recorder (Tremblay, unpublished software). Because GPS and video data were not sampled at similar rates, the video observations were related to GPS locations as followed. Each of the GPS positions was assigned to a behavioural activity based on the observations made from 2s before the position time to 2s after (i.e. including 4s * 25 frames = 100 observations), according to the following rules:</p> <p>- diving: at least one observation of diving activity during the 4 s interval time (can include some flying and/or sitting on the water)<br> - sitting on the water: study bird sitting on the water during >= 50% of the observations (can include some flying)<br> - flying: study bird flying during >50% of the observations (can include some sitting on the water)<br> The surroundings of the study bird were also directly observed, as was the presence of conspecifics.<br> Each of these observations was assigned to the closest point in time on the tracking data</p> <p>Reference:</p> <p>Tremblay, Y., Shaffer, S.A., Fowler, S.L., Kuhn, C.E., McDonald, B.I., Weise, M.J., Bost, C.-A., Weimerskirch, H., Crocker, D.E., Goebel, M.E. & Costa, D.P.

Figure 27 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 27. Display by a female Maratus personatus in response to male courtship display. 1-2, Sequential frames from a video showing a female (at left) raising and turning her opisthosoma from side to side while facing away from a nearby male (arrows). 3-6, Male displaying to a female that has turned away and raised her opisthosoma.
Figure 26 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 26 (continued). Rapid movement of legs III was sometimes asynchronous during this bilateral display (45, 48-50, 53- 56, 59-62, 64).
Figure 26 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 26 (continued). Brief intervals of no movement (e.g., 41-42) alternated with very rapid movement or vibration of the extended legs (e.g., 35, 39, and 44).
Figure 26 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 26. Sequential (1-68, continued on next two pages) video frames (25FPS, exposure 20 msec/frame) showing a male Maratus personatus displaying to a female from one position. Here consecutive frames are arranged in rows. 2, Movement of legs III from a horizontal to a vertical orientation was recorded here in a single frame (estimated duration 20-40 msec). Note the constant movement of legs III from frame to frame, including 'floppy' flexion at the femuro-patellar joint (11, 18). During pauses between rapid leg movement, legs III were generally in one of three positions: near-horizontal, near-vertical, and intermediate (V-shaped position). There was little visible movement of the pedipalps during this sequence, as the pedipalps were held in a lower position to expose the black, glabrous clypeus and chelicerae.
Figure 20 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 20. Bilateral display positions by a male Maratus personatus. As the extended and elevated legs III are waved in a transverse plane, the distal segments (beyond the femur) are often 'flopped' relative to the axis of the leg, as shown here (1, 2). Legs III may also be waved in a near vertical position (4, 5), and brought together above the spider (3, 6). Bilaterally symmetric displays like these are usually seen when the male is in a stationary position facing the female, and not stepping from side to side.
Figure 19 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 19. Developmental stages of four different female Maratus personatus. Note the light (6) and dark (17) colour variation of penultimates (6th instar).
Figure 23 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 23. Sequential (1-32) video frames (25FPS, exposure 20 msec/frame) showing a male Maratus personatus stepping to either side and waving the leading leg LIII while facing a female. 1-3, Bilateral display from a fixed position in front of the female. 4-24, Unilateral display of the leading right leg III while stepping to the right. 25-30, Bilateral display in position. 31- 32, Unilateral display of the leading left leg III while stepping to the left.
Figure 17 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 17. Developmental stages of the holotype male Maratus personatus. 12, The penultimate male (6th instar) is readily identified by its expanded pedipalps, but still has white clypeal setae like those of the female. The carapace of the 3rd instar is about 1 mm wide.
Figure 2. Four different living adult male M. personatus. 3 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 2. Four different living adult male M. personatus. 3, The scales of this male have rubbed off, exposing the black cuticle of the dorsal opisthosomal plate. 9, The small chelicerae are black and glabrous, separated on either side from a marginal band of white setae.
Figure 16 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 16. Second instar Maratus personatus. After their first moult, these spiderlings emerge from the egg-sac (nest) with well-developed eyes and footpads, and a covering of setae that suggests the appearance of an adult female. 12, The adult female (left) is about 4 times the length of a second instar (~1.6 mm).
Figure 15 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 15. Development of first instar Maratus personatus. When these first emerge from the egg (1-3), they are little more than naked embryos, with short legs and unpigmented eyes that continue to grow and develop prior to the first moult. Some authors call these prelarvae. As these grow, pigment of the retinae, dorsal carapace, and opisthosoma appears, and the legs develop to the point that the spiderlings can move about in the egg sac. Although development is continuous during most of the first instar, the more developed pre-first moult spiderlings are sometimes called larvae.
Figure 10 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 10. Views of three different living female Maratus personatus. 5, In some individuals four distinct chevrons at the rear of the dorsal opisthosoma can be seen. In other individuals these are indistinct.
Figure 1 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 1. Views of the living adult male holotype for Maratus personatus. 5, From the front, deep blue scales surround the blue anterior eyes, offset by white setae of the eye region, above, and the pedipalps, below. 12, Like other Maratus, M. personatus has a dorsal opisthosomal plate with a distinct edge (arrow), as well as a triangular tuft of white colular setae.
Figure 8 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 8. Views of three different living female Maratus personatus. From above, these are mostly dark brown to black, with tracts of off-white or ivory scales on the sides of the carapace and opisthosoma. Two or more pairs of spots (scale patches) may be seen on the dorsal opisthosoma.
Figure 21 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 21. Bilateral (1-3, 5-12) and unilateral (4, 13-14) display positions by six different male Maratus personatus. When stepping from side to side (13-14), males raise and wave the leading leg III. Bilateral display may be brief, when the male is not stepping to one side or the other.
Figure 7 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 7. Medial to lateral view of the left pedipalp of six different male Maratus personatus. Separation of the inner and outer apex of the embolus can be seen in lateral views (distinctly in 5, less distinctly in 2, 6, 9, 13 and 18). General features, including the shape and relative size of the embolus, the presence of medial tegular sclerotization proximal to the embolus, the pedipalp of the male M. personatus is much like those of other Maratus.
Figure 22 in Maratus personatus, a masked peacock spider from Cape Riche, Western Australia (Araneae: Salticidae: Euophryinae)
Figure 22. Sequential (1-24) video frames (25FPS, exposure 20 msec/frame) showing a male Maratus personatus stepping to the left and waving the leading leg LIII while facing a female. To enhance comparison of position, sequential frames are arranged in columns (as in Figures 23-25). 11-13, During a brief (~0.1 s) pause in lateral movement, one wave cycle was completed, accompanied by up and down movement of the pedipalps.
