Sneaking mating tactic has fascinated scientists for decades, and mechanisms behind its evolution remain unclear. In the December issue of Ecology, Rassim Khelifa examines sexual conflict in the rare endemic riverine damselfly, Calopteryx exul. Khelifa shows females contribute in the success of sneaker males by actively avoiding dominant males and thus securing the sneaker’s paternity.
In the December issue of Frontiers, Buxton et al. map the presence and sources of anthropogenic noise across US national parks. By analyzing thousands of hours of acoustic recordings, they were able to determine where noise sources such as vehicles, park visitors, trains, and aircraft could pose the greatest threats to wildlife behavior, physiology, and fitness.
In the December issue of Ecological Applications, Bejarano et al. show biomass of herbivorous coral reef ﬁsh increased steeply following the cessation of muroami ﬁshing in an Indonesian marine park. Although assemblages remained functionally stable, rabbitﬁshes, like this pair of Siganus puellus with distinctively pronounced snouts capable of reaching cryptic algae, were one of the families that became particularly abundant. This increase contributes to the diversity mechanisms of turf algae removal throughout the park.
In the November issue of Ecosphere, Nandintsetseg et al. utilized GPS movement data from 40 individuals of four ungulate species in the Gobi‐Steppe Ecosystem, calculating displacement distances and recursion metrics and performing a PCA, to quantify the variation in movement patterns. They found that ungulates in the resource‐rich steppe tended to move long distances with few revisits, while ungulates in the resource‐poor desert tended to move shorter distances with more revisits, suggesting that xeric and mesic habitats promote different types of nomadic strategies.
Many species of shorebirds migrate long distances to raise their young on a seasonal burst of prey invertebrates in tundra habitats during a short Arctic summer. Long-term changes in the timing of snowmelt and the interaction between temperature and snow phenology have led to greater phenological mismatch between the two trophic levels, as reported by Kwon et al. in the November issue of Ecological Monographs.
Hettinger et al. introduce a new series in the ESA Bulletin, Human Dimensions. Future works in this series will highlight different ESA sections and chapters and the work they are doing to more tightly couple ecology to human systems, and to further goals of equity, inclusion, and diversity in the study of ecology. –Designing Instruction and Assessing Student Learning
