What Do the First 597 Global Fungal Red List Assessments Tell Us about the Threat Status of Fungi?

Fungal species are not immune to the threats facing animals and plants and are thus also prone to extinction. Yet, until 2015, fungi were nearly absent on the IUCN Red List. Recent efforts to identify fungal species under threat have significantly increased the number of published fungal assessments. The 597 species of fungi published in the 2022-1 IUCN Red List update (21 July 2022) are the basis for the first global review of the extinction risk of fungi and the threats they face. Nearly 50% of the assessed species are threatened, with 10% NT and 9% DD. For regions with a larger number of assessments (i.e., Europe, North America, and South America), subanalyses are provided. Data for lichenized and nonlichenized fungi are also summarized separately. Habitat loss/degradation followed by climate change, invasive species, and pollution are the primary identified threats. Bias in the data is discussed along with knowledge gaps. Suggested actions to address these gaps are provided along with a discussion of the use of assessments to facilitate on-the-ground conservation efforts. A research agenda for conservation mycology to assist in the assessment process and implementation of effective species/habitat management is presented

Chrysomya albiceps (Wiedemann) and Hemilucilia segmentaria (Fabricius) (Diptera, Calliphoridae) used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil

Chrysomya albiceps (Wiedemann) e Hemilucilia segmentaria (Fabricius) (Diptera, Calliphoridae) utilizadas para estimar o intervalo pós-morte em um caso forense em Minas Gerais, Brasil. O cadáver de um homem foi encontrado em uma área de cerrado no Estado de Minas Gerais. Larvas de moscas foram coletadas na cena do crime e encaminhadas ao laboratório em três dias. Os adultos que emergiram em laboratório foram identificados como Chrysomya albiceps (Wiedemann, 1819) e Hemilucilia segmentaria (Fabricius, 1805). Uma vez que insetos utilizam o cadáver como uma fonte de recurso alimentar, sua taxa de desenvolvimento pode ser empregada como uma ferramenta para estimar o intervalo pós-morte. O estágio de desenvolvimento pós-embrionário dos imaturos coletados no cadáver foi estimado como sendo a diferença entre o tempo total de desenvolvimento e o tempo necessário para a emergência destes adultos em laboratório. A idade estimada dos imaturos das duas espécies, bem como o intervalo pós-morte mínimo, foi de quatro dias. Este é o primeiro relato do uso de Hemilucilia segmentaria para estimar o intervalo pós-morte em um caso forense.Chrysomya albiceps (Wiedemann) and Hemilucilia segmentaria (Fabricius) (Diptera, Calliphoridae) used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado) in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819) emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805) were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case
