Abstract The high-Arctic has the world’s simplest terrestrial vertebrate predator-prey community, with the collared lemming (Dicrostonyx groenlandicus) being the single main prey of four predators, the Snowy Owl (Bubo scandiacus), Arctic fox (Vulpes lagopus), Long-tailed Skua (Stercorarius longicaudus), and stoat (Mustela erminea). Using a 20-year time series and a model that has been previously parameterized with data from northeast Greenland, we analysed the population and community level consequences of the ongoing and predicted climate change. Species’ responses are complex, because in addition to the direct effects of climate change, which vary depending on species’ life histories, species are affected indirectly through interactions with their prey and predator species. The lemming-predator community exemplifies these complications, yet a robust conclusion emerges: in practically all scenarios and for the ranges of parameter values examined, climate change increases the length of the lemming population cycle and decreases the maximum densities reached during the fluctuations. The latter change, in particular, is detrimental to populations of their predators, which are adapted to make use of the years of prey abundance. Indeed, in northeast Greenland, even the Gyrfalcon is strongly dependent on lemmings, for the densities of larger prey as Arctic hare and ptarmigan are too low in most years.
Therefore, climate change will indirectly induce a decline in predators’ reproductive success and population densities, and may ultimately lead to local extinctions of some of the predator species. Based on these results, we conclude that the recent anomalous observations of lemming population dynamics may well be the first signs of a severe impact of climate change on the lemming-predator communities in northeast Greenland and presumably also elsewhere in the high-Arctic

Title (down) Wild skuas can use acoustic cues to locate hidden food Type Journal
Year 2022 Publication Animal Cognition Abbreviated Journal
Volume Issue Pages
Keywords Acoustic cue Cups task Exclusion performance Inferential reasoning by exclusion Shaking
Abstract Among animals, the visual acuity of several predatory bird species is probably the most outstanding. This, and the ease with which visually based tasks are administered, has led researchers to predominantly use the visual modality when studying avian cognition. Some wild skua populations routinely use acoustic cues emitted by their prey during foraging. In this study, we thus assessed whether this species was able to locate hidden food using acoustic cues alone (training phase). During the subsequent test phase, we investigated the capacity of successful individuals to choose the correct baited container in four conditions: (i) baited (shaking the baited container), (ii) full information (shaking both containers), (iii) exclusion (shaking the empty container), and (iv) control (shaking neither container). Four out of ten subjects succeeded in locating the baited container in the training phase. During the test phase, most subjects chose the baited container significantly more than the empty container in the baited and full information condition, while their performance was at chance level in the control condition. When no sound emanated from the empty container in the exclusion condition, one out of four skuas chose the baited container with more accuracy than predicted by chance. As this bird chose correctly on the first trial and during the first five trials, its performance is unlikely due to learning processes (learning to exclude the empty container). Although further tests are necessary to draw firm conclusions, our results open the way for assessing further this species’ reasoning abilities in the wild.

Title (down) Wild skuas can follow human-given behavioural cues when objects resemble natural food Type Journal
Year 2022 Publication Animal Cognition Abbreviated Journal
Volume 26 Issue 2 Pages 709-713
Keywords Choice task Human–animal communication Neophobia Skua Social cue Social learning
Abstract The capacity to follow human cues provides animals with information about the environment and can hence offer obvious adaptive benefits. Most studies carried out so far, however, have been on captive animals with previous experience with humans. Further comparative investigation is needed to properly assess the factors driving the emergence of this capacity under natural conditions, especially in species that do not have longstanding interactions with humans. Wild brown skuas (Catharacta antarctica ssp. lonnbergi) are non-neophobic seabirds that live in human-free habitats. In test 1, we assessed this species’ capacity to use human behavioural cues (i.e., pecking at the same object previously picked up and lifted by a human experimenter) when the items presented were food objects: anthropogenic objects (wrapped muffins) and natural-food-resembling objects (plaster eggs). In test 2, we examined the response of another skua population towards non-food objects (sponges). Although all skuas in test 1 pecked at the objects, they pecked significantly more at the same previously handled items when they resembled natural food (plaster eggs). Most skuas in test 2, however, did not approach or peck at the non-food objects presented. Our results lead us to suggest that the use of human behavioural cues may be influenced by skuas’ foraging ecology, which paves the way to further field studies assessing whether this capacity is directed specifically towards food objects and/or develops after previous interaction with humans.
