To support conservation efforts of caribou, it is integral to develop both historical and modern datasets; these datasets allow us to understand how caribou have adapted to past climatic shifts and may respond to future change. Caribou are the only extant species in which both males and females grow antlers each year, providing unique sex-specific isotope datasets. Isotopic study of antlers is proving to be a source of annualized data on caribou diet and migration, but uncertainty remains in the magnitude and drivers of isotopic changes across individual antlers. Nitrogen (δ¹⁵N_Col) in male antlers from the Qamanirjuaq herd has been shown to increase along the main antler beam aligned with known shifts in seasonal diet and/or the increased energy requirements. We examined 19 female antlers from the same population to compare δ¹³C_Col and δ¹⁵N_Col between sexes and among varying reproductive statuses. Female antlers were found to be ~0.4‰ lower in δ¹³C_Col at the bases of their antlers compared to males. In both sexes, caribou antler collagen varied in δ¹³C_Col among individuals by ~2‰ (−20.0‰ to −18.1‰) and in δ¹⁵N_col by ~5‰ (+2.3‰ to +7.3‰). We conclude that δ¹³C_Col differences between sexes are the result of differing diets during the onset of antler formation, corresponding to the different seasons that females and males initiate antler growth. Despite dietary differences, both males and females increased in δ¹⁵N_Col along the antler beam by approximately 1‰–1.5‰. Increases in δ¹⁵N_Col along the antler beam coincide with the increased physiological stress and material demands during antler development.

Predators often target vulnerable life stages of prey, but how prey females adjust their reproductive strategies in response to cues from injured conspecifics of these stages remains unclear, particularly in haplodiploid species, where mothers can adjust offspring sex ratios in response to social environments. Using the predatory mite <i>Phytoseiulus persimilis</i> and its prey, the spider mite <i>Tetranychus ludeni</i>, we first investigated the stage-specific vulnerability by exposing <i>T. ludeni</i> eggs, deutonymphs, and female adults to <i>P. persimilis</i> for choice. We then tested whether ovipositing <i>T. ludeni</i> females adjusted reproductive performances and survival when exposed to potential predatory cues from those injured conspecifics. Results show that <i>P. persimilis</i> significantly preferred <i>T. ludeni</i> eggs for feeding, indicating their higher vulnerability to predators. <i>T. ludeni</i> females responded most strongly to potential predatory cues from injured eggs, reducing fecundity and producing smaller eggs, but without trading off their longevity. Additionally, when exposed to injured adult cues, <i>T. ludeni</i> females adjusted offspring sex ratios, producing more dispersing daughters by fertilizing more smaller eggs, an evolved strategy to escape from the risky environments. In contrast, egg hatching and immature survival were unaffected by conspecific cues. Our results demonstrate that <i>T. ludeni</i> females may discriminate among cues from injured conspecifics of different life stages, with the strongest vigilance elicited by cues from the most vulnerable stage (i.e., eggs). This study highlights the role of indirect, life stage-specific cues in shaping antipredator strategies and reveals that non-consumptive effects of predation risk could influence prey population dynamics in ways beyond direct predation.

Mixed effect models revealed that home range size estimates significantly decreased with less frequent tracking events.
