A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

open access: yesWildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

open access: yesWildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Predicting disease spread from host movement data: Chronic wasting disease in North America as a case study

open access: yesJournal of Animal Ecology, EarlyView.
This paper estimates the rate of chronic wasting disease spread in multiple regions and compares these rates with model predictions based on deer movement data. Abstract Rare long‐distance movements can increase the spatial spread of invasive species and shifts in species ranges. For wildlife disease spread, however, seasonal migrations may only matter

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Scholars of inequality generally find that lower‐class individuals are more skeptical of meritocratic narratives that link economic success to individual work effort. However, past research has yielded inconclusive findings about how economic inequality affects meritocratic attitudes across different class groups.

Graduated Involution Under Compressed Modernity: Differences in the Summer Holidays as a Phase in the Public Life‐Course in Shanghai, China

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT This paper develops the concept of graduated involution to explain how summer holidays have been reconstituted from leisure time into an educational arena for Chinese families under conditions of compressed modernity. Based on qualitative data from 32 households in Shanghai, including interviews and child self‐recordings, we analyze how ...

The wider network of social relationships and desistance from crime

open access: yesCriminology, EarlyView.
Abstract Prior research has focused on marriage as a key relationship associated with crime cessation. Yet particularly within the contemporary context, relationships with parents, peers, and other family members may also foster or inhibit progress toward desistance.

Punishment begets punishment: An exploration of racial variation in school‐to‐prison pipeline mechanisms

open access: yesCriminology, EarlyView.
Abstract To mitigate the consequences of school punishment, we must move from documenting the school‐to‐prison pipeline (STPP) toward understanding how punishment increases criminal legal system involvement. Beyond impacting academic performance, punishment may encourage disengagement from school, teachers, and peers; delinquency; and secondary ...
