The status of the world's land and marine mammals: diversity, threat, and knowledge

Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mechanisms driving diversity and endemism across systems. Compared with land species, threat levels are higher among marine mammals, driven by different processes (accidental mortality and pollution, rather than habitat loss), and are spatially distinct (peaking in northern oceans, rather than in Southeast Asia). Marine mammals are also disproportionately poorly known. These data are made freely available to support further scientific developments and conservation action

Excessive Revocations in Wisconsin: The Health Impacts of Locking People Up without a New Conviction

Revocation—being incarcerated for breaking the rules of a supervision arrangement (like parole, probation, or extended supervision)—feeds the mass incarceration cycle in the United States. Estimates suggest that across the U.S., half of the people in jails and more than one-third of the people entering prison are locked up for a revocation.A large number of people are incarcerated for breaking the rules of supervision, but do not commit a new crime. In Wisconsin, the Department of Corrections (DOC) put about 3,000 people in prison in 2015 alone for what DOC calls a "revocation without a new offense," meaning there was not a new criminal conviction. These people will serve an average of 1.5 years in prison without being convicted of a new crime—and cost Wisconsin $147.5 million dollars in the process
