Capitalizing on developments in genome sequencing technology, the Biodiversity Cell Atlas is a multinational project that uses single-cell transcriptomics to map cell types of whole organisms across the tree of life.
Chemical pollution research should be better integrated with other drivers of biodiversity loss and the assessment of human impacts on ecosystems, to more effectively guide management strategies for biodiversity loss mitigation.
The Taskforce on Nature-related Financial Disclosures is a key initiative that seeks to convince companies and financial institutions to manage nature-related risks. Its inherent structures — market-led, voluntary and corporate-governed — present challenges that should be addressed during the final development and initial implementation of the framework.
An analysis of millions of wildlife photographs has revealed that survival and colonization probabilities of mammals in protected areas are associated with people and what they do both inside and outside these areas.
Camera-trap data for 159 mammalian species at 1,002 sites across 16 tropical-forest protected areas show how local survival and colonization probabilities of specialist and generalist species are differently affected by human-induced stressors at different spatial scales, such as human population density and forest fragmentation.
Fungi exhibit remarkable morphological and ecological diversity. An analysis of the genomes of 123 fungi and relatives shows gradual loss of protist genes, major gene turnover and duplication leading to the evolution of modern traits of filamentous fungi.
The authors report isotopic data from ravens from Pavlovian (29,000–25,000 yr bp) archaeological sites that indicate ravens were consuming the same range of foods as commensal humans at the sites, which the authors refer to as ‘incipient synanthropism’.
Atmospheric CO2 concentration measured across a network of towers in North America shows that continent- and biome-scale measurements of the temperature sensitivity of ecosystem respiration are lower than have previously been estimated from plot-level studies.
Research codes and contracts have been developed to protect Indigenous and marginalized peoples from exploitation and to promote inclusion, so that research will become more beneficial to them. We highlight three important but often overlooked challenges for such instruments, drawing on examples from the San of southern Africa.
Sex differences in physiology and longevity are widely observed. A study that manipulates heterochromatin content in Drosophila Y chromosomes shows no association between the length of the Y chromosome and longevity, thus challenging the hypothesis that Y chromosome-derived heterochromatin causes Y chromosome-bearing animals to live shorter lives.
