Influence of sea turtle nesting on hunting behavior and movements of jaguars in the dry forest of northwest Costa Rica
Jaguars (Panthera onca) are opportunistic predators that prey on large profitable prey items, such sea turtles at nesting beaches. Here we use jaguar and sea turtle track count surveys, combined with satellite telemetry of one jaguar, to evaluate whether jaguar hunting behavior and movements are influenced by seasonal sea turtle nesting in the Sector Santa Rosa of Área de Conservación Guanacaste in northwest Costa Rica. We used Generalized Linear Models to evaluate the effect of moon phase and sea surface temperature on olive ridley (Lepidochelis olivacea) and green turtle (Chelonia mydas) nesting abundance, as well as the combination of these predictors on the frequency of jaguar predation activity (proximity to nesting beaches) and movements. For home range size and location analyses, we calculated Kernel Density Estimates for each season at three different temporal scales. Sea turtle nesting season influenced jaguar activity patterns, as well as sea turtle abundance was related to jaguar locations and predation events, but jaguar home range size (88.8 km2 overall) did not differ between nesting seasons or among temporal scales. Environmental conditions influenced sea turtle nesting and, as a consequence, also influenced jaguar movements and foraging activity. Our study defined the home range of a female jaguar in the tropical dry forest and its relationship to seasonally abundant turtles. Additional information related to the effect of tourism on jaguar-sea turtle interactions would improve conservation of these species at unique nesting beaches in the area.
Data for: Hunting behavior of a solitary sailfish Istiophorus platypterus and estimated energy gain after prey capture
<p>Foraging behavior and interaction with prey is an integral component of the niche of predators but is inherently difficult to observe for highly mobile animals in the marine environment. Billfish have been described as 'energy speculators', expending a large amount of energy foraging, expecting to offset high costs with periodic high energetic gain. Surface-based group feeding of sailfish, <em>Istiophorus</em> <em>platypterus</em>, is commonly observed, yet sailfish are believed to be solitary roaming predators with high metabolic requirements, suggesting that individual foraging also represents a major component of predator-prey interactions. Here, we use biologging data and video to examine daily activity levels and foraging behavior, estimate metabolic costs, and document a solitary predation event. We estimate a median active metabolic rate of 218.9 ± 70.5 mgO<sub>2</sub> kg<sup>-1</sup> h<sup>-1</sup> which increased to 518.8 ± 586.3 mgO<sub>2</sub> kg<sup>-1</sup> h<sup>-1</sup> during prey pursuit. Assuming a successful predation, we estimate a daily net energy gain of 2.4 MJ (5.1 MJ acquired, 2.7 MJ expended), supporting the energy speculator model. While group hunting may be a common activity used by sailfish to acquire energy, our calculations indicate that opportunistic individual foraging events offer a net energy return that contributes to the fitness of these highly mobile predators. </p>

Fig. 2 in Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
Fig. 2. Cumulative species richness based on consecutive samples (open circles) as well as Chao 1 (open diamonds) and Michaelis-Menton estimates of species richness (solid circles). Values calculated using Primer version 6.1.13 software.
Fig. 4 in Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
Fig. 4. Examples of mixed-species hunting groups from ca. 50-80 m depth at the Everest deep pinnacle site. (A) Caranx melampygus, Caranx lugubris, Mycteroperca olfax hunting in groups around the steep upper slope and peak, where smaller prey fish like Paranthias colonus aggregate in the water column. Periodic attacks by single fish and adjacent pairs were observed. (B) C. melampygus, C. lugubris and M. olfax move as a group but widely spaced in this setting. Individual fish attacked proximate prey that reacted to nearby predators. (C) Seriola rivoliana, D. dermatolepis, Lutjanus argentiventris, Bodianus diplotaenia and Aulostomus chinensis hunt for prey amongst corals and within crevices. (D) Image recorded soon after C (previous image) illustrating D. dermatolepis and B. diplotaenia entering, and A. chinensis emerging from a dense patch of corals to hunt while S. rivoliana maneuver above to encounter potential escaping prey. (E) M. olfax and L. argentiventris follow a moray eel (hidden within narrow crevice). (F) Large group of S. rivoliana and M. olfax move in tandem around the summit and upper slope, with occasional attacks by individuals on potential prey.

Fig. 6. Relationships between three metrics of network connectivity in order to identify important species within the behavior web (species pair-wise links = open diamond and dotted line, total occurrences per species = open triangle and dashed line, network strength = solid circle and solid line). Species on x-axis in descending order based on value of pair-wise links (as in Tab. 1). Regression lines are based on the power function. Eigenvector centrality values (open circle) plotted for comparison.
Fig. 8 in Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
Fig. 8. Linear regression of total pair-wise links in the behavior web on species richness (links = -781.8 + 32.08 S; r2 = 99.1) based on fisheries removal simulation. Noteworthy is the rapid decline in linkages within the behavior web with removal of only several key species. The reduction in species richness is with the sequential removal of first Caranx melampygus and Trianodon obesus, then Dermatolepis dermatolepis, Caranx lugubris and Bodianus diplotaenia from the data set in this study (see text for detailed explanation).
