Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published.Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.Benefits to authorsWe also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.

Environmental DNA is a fully double-blinded peer reviewed open access journal. The journal publishes papers that pertain to the analyses of environmental DNA (eDNA) (including ancient DNA, non-invasive sampling, diet analyses, metabarcoding, metagenomics, microbial ecology and pathogens) and address questions of both basic and applied relevance. Research areas (and non-exclusive examples of applications) of interest to Environmental DNA include but are not limited to:

• Experimental eDNA work: Testing the impact of physico-chemical factors (e.g. natural biogeochemistry and PCR pollutants) on eDNA, degradation, transport, shedding and detection rate, comparing detectionand abundance estimate with conventional methods.
• Trophic and community ecology: Ecosystem dynamics, functional diversity, predator-prey interactions (e.g. diet analysis), host-associated microbiota.
• Palaeo-environments: Past species and community diversity and abundance measurements, inference in space and time.
• Biomonitoring, conservation biology: Single- and multi-species detection, comprehensive biodiversity at different scales, abundance estimates, detection of rare, cryptic and endangered species, non-invasive sampling, management (e.g. fisheries), occurrence and detection estimates.
• Invasion biology: Early species detection at low abundance, passive surveillance, impacts on ecosystems, vectors and pathways of dispersal.
• Environmental assessment: Impacts of pollutants and other environmental disturbance on species and communities, microbial source tracking (fecal bacteria or pathogens).
• Physical eDNA properties: Uptake and transformation based on geochemistry, particles, organic chemistry or microbial community.
• Techniques and methods: Engineering development, developing, testing and evaluating eDNA biotechnology and biostatistical approaches.
• Applications in citizen science and biodiversity education

Geochemistry: Exploration, Environment, Analysis focuses on the use of geochemistry in mineral exploration/resource development and environmental issues related to mining.
