A Tale of Two Programs? Stigma and Administrative Burdens in CHIP and Medicaid
World Medical &Health Policy, Volume 18, Issue 1, March 2026.ABSTRACT One contributing factor to undersubscriptions is administrative burdens. To explore whether program stigma affects attitudes about administrative burdens, a survey (N = 2204) was fielded to assess differences in attitudes about seven policies decreasing administrative burdens and two policies increasing administrative burdens.

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little
