Fig. 2. Results of Periodic Regression Model fit to MIA values (dots) for asteriscus otoliths of Pseudoplatystoma metaense (solid line) compared with Apure River flood cycle (dashed line), for the periods June 2000-May 2001 and June 2002-April 2003. Arrows indicate approximate times of opaque zone (annulus) formation in the otoliths.

Fig. 1 in Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes)
Fig. 1. Growth of Sympterygia bonapartii born at Temaikèn Aquarium (Argentina). Individual growth trajectories (n = 21 males and 13 females) are shown as grey lines. The Logistic model (bold black line) is the one with the best fit to the data (lowest Akaike Information Criterion). Other models fitted are von Bertalanffy with size at birth (VB1), von Bertalanffy with t0 parameter (VB2), and Gompertz models. The best model describing the growth of wild S. bonapartii (bold dashed line) from off northern Argentina, as estimated by Hozbor and Massa (2015), has the same form as VB1.

Fig. 3. Percentage of days with Conorhynchos conirostris captures per CPUEn class by fishing site for artisanal (top panel) and sport (bottom panel) fishing. (CPUEn = 0 corresponds to days with zero pirá captured; N = number of sampling days; the Pirapora-São Romão fishing site does not include data from 1987).
Figure 1 in Diversity and life-history traits of wild bees (Insecta: Hymenoptera) in intensive agricultural landscapes in the Rolling Pampa, Argentina
Figure 1. Location of (a) the Argentinean Pampas in South America, (b) the study site (Estancia 'Las Polvaredas', partido de Rojas, provincia de Buenos Aires; black square) in the Rolling Pampa and (c) the 39 sampling points in the study site. The map shows the land use of the year when bee sampling occurred (2010–2011 growing season). Black dots represent points located in the cropped area (n = 28), and white dots represent points located in the semi-natural area (n = 11). On each point, bees were collected with pan traps (one blue, one white and one yellow) during three 48- hour sessions.

Figure 6 in Diversity and life-history traits of wild bees (Insecta: Hymenoptera) in intensive agricultural landscapes in the Rolling Pampa, Argentina
Figure 6. Mean number of (a) bee individuals, (b) non-Lasioglossum (Dialictus) bee individuals and (c) bee taxa per point, in cropped area (n = 28 points) and semi-natural area (n = 11 points). ns indicates a non-significant result. Asterisks indicate that means are significantly different (Wilcoxon rank sum test, *** = P <0.001). Bars show SEs.

Figure 13. Illustrations of prey capture by (A) Grippina coronata; (B) Spheniopsis brasiliensis; and (C) Cuspidaria rostrata, all drawn to approximately the same scale. (A redrawn partly after Morton et al. (2015, fig. 24 C) and C redrawn partly after Reid and Reid (1974, fig. 1). Possible prey items are also identified. The arrows show how evolution of the rostrum has allowed deeper residence of the sediments presumably for enhanced protection.
