The OCLC Research WorldCat Identities project is ending. The work provided valuable insight into how to mine bibliographic data for insight into the People and Organizations that create and serve as subjects library materials. The findings demonstrated the power of data mining over the world’s largest set of bibliographic metadata and highlighted the value of collaborative collective cataloging. The WorldCat Identities data has positively impacted OCLC’s work to build the WorldCat Entities application and the 150 million Person and Work descriptions accessible through it. This work will continue to build our entity ecosystem to support the future knowledge work of librarians.

The WorldCat Identities web application will be retired and shut down in the coming months and the data is no longer being updated. The most recent version of the data is from July of 2022. As OCLC continues to build out the WorldCat Entities ecosystem, please use it as a source for persistent Person identifiers.

Atlas of the Mammals of Great Britain and Northern Ireland by Derek Crawley( )

2 editions published in 2020 in English and held by 27 WorldCat member libraries worldwide

Fully illustrated with photographs, detailed high-resolution distribution maps are provided for 89 species, together with descriptions of their ecology and identification, and graphs showing the seasonal distribution of records.

Working Group on Marine Mammal Eclogy (WGMME) by Markus Ahola( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

The Working Group on Marine Mammal Ecology met in 2021 to address new information on marine mammal ecology relevant to management. Two terms of references were standing ToRs; under the first of these, ToR A, new and updated information on seal and cetacean population abundance, population/stock structure, manage-ment frameworks as well as anthropogenic threats to individual health and population status were reviewed along with findings on threats to marine mammals such as bycatch, pollution, marine debris and noise. ToR B is a cooperation with WGBIODIV to review species-specific for-aging distributions (considering horizontal and vertical dimensions depending on data availa-bility) and to estimate consumption by marine mammal species representative in case study ar-eas. ToR C was implemented to review aspects of marine mammal fishery interactions not cov-ered by ICES WGBYC. ToR D is the second standing ToR and concerns updating the WGMME seal database, which was updated with the latest data. Regarding ToR A, seal stocks in the North Atlantic are generally growing and stable, except both grey and harbour seals in Iceland, which have both declined dramatically in recent decades. Also, harbour seals in some areas of northern UK are declining, and the southern Baltic ringed seal subpopulation is threatened by climate change. Suggestions for calculation of Potential Bio-logical Removal (PBR) for grey seals in OSPAR regions I, II and III are also provided. Recent surveys for estimating cetacean species abundance are presented as well as updates on anthro-phonic threats, such as pollution. Under ToR B it was emphasized that when estimating diet and prey consumption of marine mammals, aspects like (1) non-representativeness of samples (e.g. stomachs from stranded or bycaught individuals or scats from seal haul outs) for the population, (2) not recoverable remains of some prey items and (3) the partially (and maybe completely) digestion of hard prey remains in the gastro-intestinal tracts of the predator, are important to consider. To illustrate the available data and metainformation some example case studies were summarised. An outline methodol-ogy for combining and analysing data useful for prey guild modelling and ECOPATH modelling is presented. Under ToR C, Regulations for acoustic deterrent devices to mitigate marine mammal bycatch and legislation requirements for monitoring of bycatch were reviewed along with updated in-formation on bycatch. A questionnaire survey to European stranding networks mapped infor-mation pertinent to bycatch assessments
