By Nadav Nur 10/7/2019 We used Point Blue’s long-term data to examine the complex relationship between house mice, burrowing owls, and ashy storm-petrels on the Farallon Islands National Wildlife Refuge and to provide a quantitative estimate of the anticipated benefit to ashy storm-petrels from a proposed house mouse eradication project. Surveys by Point Blue biologists revealed a strongly seasonal pattern…
By Sarah Nicholas, Mississippi State University 10/2/2019 STARKVILLE, Miss.—Mississippi State University researchers are shifting commonly held ideas about the diet of grey wolves in a newly published article gaining national attention. Published in the scientific journal “Ecology,” MSU assistant professor Brandon Barton’s Sept. 18 article “Grasshopper consumption by grey wolves and implications for ecosystems” details the unexpected effects of wolf reintroduction…
By Trent Knoss, CU Boulder 10/2/2019 BOULDER, CO – A lack of tree seedling establishment following recent wildfires represents a crucial bottleneck limiting coniferous forest recovery in the western U.S., new CU Boulder-led research finds. The study, which was recently published in the journal Ecological Applications, examined burn-affected ponderosa pine and Douglas-fir stands in southern Colorado and northern New Mexico to better understand…

In the October issue of Ecological Applications, Graham et al. demonstrate that responses to land-use change differ among plants, small mammals, and large mammals in east Africa. Large mammals like the giraffe depend on conserved areas, while many small mammal and plant taxa exhibit affinities for pastoral and agricultural areas. This implies that mosaics of varying land-use are important for conserving diverse assemblages of organisms.
In their research published in the August issue of Ecological Monographs, Nowicki et al. quantified impacts of widespread seagrass loss to tropical marine megafauna, revealing that marine heat waves during extreme climatic events can have dramatic indirect impacts to consumer species, even when they withstand the heat wave itself.
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
In the September issue of Ecosphere, Grimm-Seyfarth et al. investigated the effects of food, predators, vegetation, and local and distant climate on a reptile community over the course of 30 years. The study findings suggest a highly complicated network rather than linear relations between climatic factors and biotic interactions, and, interestingly, the biotic or abiotic factor to which a species responded was determined by its functional traits, such as activity, habitat, body lengths, or longevity.
Some types of human infrastructure, such as roads and railways, can facilitate seed dispersal, but pollution, habitat fragmentation, and other stressors that occur in urban areas can make it more difficult for plants to expand their populations. In the October issue of Frontiers, Piana et al. describe how conditions in cities can influence plant recruitment, and show how a better understanding of these conditions could improve urban ecosystem management.
In the October issue of Ecology, Butterfield et al. show that as temperatures rose following the Last Glacial Maximum, some tall, vertebrate-dispersed desert species like the giant saguaro colonized newly suitable habitat 2,000–5,000 years faster than short species with no long-distance dispersal mechanisms.
