Agricultural Informatics Contributions to Biodiversity Science and Biodiversity Assessments [PDF]

open access: yesProceedings of TDWG, 2017
Agricultural biodiversity has long been ignored by the traditional biodiversity community and the aggregators of their data. The Arnaud et al. (2016) GBIF "Final Report of the Task Group on GBIF Data Fitness for Use in Agrobiodiversity," provided recommendations primarily regarding crops and their wild relatives, but did not address wider issues of ...

Macroinvertebrate community diversity and habitat quality relationships along a large river from targeted eDNA metabarcode assays

open access: yesEnvironmental DNA, 2020
Species compositions and diversity levels of aquatic macroinvertebrate communities provide important indicators of ecosystem health. However, such community analyses typically are limited by time and effort of sampling, sorting, and identifications, as ...

Bridging the biodiversity data gaps: Recommendations to meet users’ data needs [PDF]

open access: yes, 2013
A strong case has been made for freely available, high quality data on species occurrence, in order to track changes in biodiversity. However, one of the main issues surrounding the provision of such data is that sources vary in quality, scope, and ...

Analytical approaches for evaluating passive acoustic monitoring data: A case study of avian vocalizations

open access: yesEcology and Evolution, 2022
The interface between field biology and technology is energizing the collection of vast quantities of environmental data. Passive acoustic monitoring, the use of unattended recording devices to capture environmental sound, is an example where ...

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification

open access: yesFrontiers in Marine Science, 2021
Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions.

Biodiversity soup: metabarcoding of arthropods for rapid biodiversity assessment and biomonitoring [PDF]

open access: yesMethods in Ecology and Evolution, 2012
Summary1. Traditional biodiversity assessment is costly in time, money and taxonomic expertise. Moreover, data are frequently collected in ways (e.g. visual bird lists) that are unsuitable for auditing by neutral parties, which is necessary for dispute resolution.2.

Evaluating On-Farm Biodiversity: A Comparison of Assessment Methods [PDF]

open access: yes, 2018
Strategies to stop the loss of biodiversity in agriculture areas will be more successful if farmers have the means to understand changes in biodiversity on their farms and to assess the effectiveness of biodiversity promoting measures.

RECONCILING METHODOLOGICALLY DIFFERENT BIODIVERSITY ASSESSMENTS [PDF]

open access: yesEcological Applications, 2005
Ongoing large-scale habitat disturbance requires quick identification of conservation priorities such as targeting sites rich in species and/or endemics. Biodiversity assessments are time consuming and expensive, so surveys often rely on partial sampling.
