Abstract Understanding the movement of individuals across natural habitats is important to determine fundamental aspects of their ecology, from dispersal patterns and habitat selection to interactions with predators, pathogens or conspecifics. Amphibian larvae are key to aquatic systems, playing fundamental roles as both consumers and prey, affecting nutrient cycling and even physico-chemical properties of the water bodies they occupy. Nevertheless, despite an extensive body of literature on most other aspects of their ecology, we know very little about spatial movements of amphibian larvae in their natural habitats, and the little information we have is restricted to lotic systems. Here we use a mark-and-recapture procedure using elastomers to determine movement patterns and microhabitat selection of western spadefoot toad tadpoles (Pelobates cultripes) in two large ponds in southwestern Spain. We observed maximum distances moved by these tadpoles of >67 m and >245 m, depending on the pond. These distances coincided with the maximum cross distance in each pond, suggesting that they could potentially move even farther in larger wetlands. Mean distances moved were 29.7 and 105 m in each pond. We sampled at two, four and nine days after release of tagged individuals, and we observed a stable, not expanding, movement pattern across sampling dates, suggesting that tadpoles resumed normal activity immediately after release. Tadpoles showed preference for deeper and more densely vegetated areas of the ponds, especially associated with plant species such as Ranunculus peltatus and Potamogeton pectinatus.

Abstract Body temperature and movement patterns of Angus Hereford crossbred (AH) vs. Raramuri Criollo (RC) nursing cows were monitored in summer 2016 and 2017. AH and RC cows grazed separately in two adjacent Chihuahuan Desert pastures (1190ha, 1165ha) in a crossover design for 4 weeks each year. Body temperature (BodyT) was monitored at 10 min intervals by placing blank CIDRs containing a temperature logger in 10 cows per breed. Seven to 9 AH and RC cows were also fitted with GPS collars that recorded position and ambient temperature (CollarT) at 10 min intervals. A landscape thermal map (LandT) was developed for habitat analysis. Data were analyzed within four daytime segments: dawn (sunrise to 9AM); pre-noon (9AM to noon); post-noon (noon to 3PM); and dusk (3PM to sunset). ANOVA was used to determine whether BodyT, animal movement, CollarT, and mean LandT position within each day segment were different for AH vs. RC cows. Breed nested within Year*Pasture was treated as the experimental unit. BodyT increased as a day progressed and was higher (P < 0.05) in AH vs. RC during post-noon (38.83 vs. 38.42oC) and dusk (39.22 vs. 38.70oC). Compared to AH counterparts, RC cows traveled farther (4.7 vs. 2.7 km*daytime h-1, P < 0.05), at higher velocities (5.9 vs. 3.5 m*min-1, P < 0.05) and spent more time grazing (5.6 vs. 4.3 daytime h; P < 0.05) and traveling (0.7 vs. 0.3 daytime h; P < 0.05) during all four daytime segments. Largest breed differences were observed during the hottest segments of the day (post-noon and dusk). Increasing CollarT throughout a day was associated with selection of cooler landscape locations (LandT) in both breeds. Apparent lower body heat load in RC cows may reduce constraints on their movement patterns compared to AH cows grazing Chihuahuan Desert rangeland in summer.
