There has been major progress over the last two decades in digitising historical knowledge of biodiversity and in making biodiversity data freely and openly accessible. Interlocking efforts bring together international partnerships and networks, national, regional and institutional projects and investments and countless individual contributors, spanning diverse biological and environmental research domains, government agencies and non-governmental organisations, citizen science and commercial enterprise. However, current efforts remain inefficient and inadequate to address the global need for accurate data on the world's species and on changing patterns and trends in biodiversity. Significant challenges include imbalances in regional engagement in biodiversity informatics activity, uneven progress in data mobilisation and sharing, the lack of stable persistent identifiers for data records, redundant and incompatible processes for cleaning and interpreting data and the absence of functional mechanisms for knowledgeable experts to curate and improve data. The first Global Biodiversity Informatics Conference (GBIC) in 2012 delivered the Global Biodiversity Informatics Outlook (GBIO, Hobern et al. 2012), an architectural vision for the major components of a distributed global infrastructure for biodiiversity information, but realigning the work of existing organisations and projects to achieve this vision remains challenging. Recognising the need for greater alignment between efforts at all scales, the Global Biodiversity Information Facility (GBIF) convened the second Global Biodiversity Informatics Conference (GBIC2) in July 2018 to propose a coordination mechanism for developing shared roadmaps for biodiversity informatics. GBIC2 attendees reached consensus on the need for a global alliance for biodiversity knowledge, learning from examples such as the Global Alliance for Genomics and Health (GA4GH) and the open software communities under the Apache Software Foundation. These initiatives provide models for multiple stakeholders with decentralised funding and independent governance to combine resources and develop sustainable solutions that address common needs. GBIF was asked to coordinate next steps following GBIC2, including publication of a paper, Connecting data and expertise: a new alliance for biodiversity knowledge (Hobern et al. 2019). The supplementary materials for the paper include PDF brochures explaining the concept in eleven languages. During 2019, GBIF is coordinating further consultations to establish an optimal model for the governance and operations of the alliance and to advance collaboration around some of the major building blocks of the GBIO. Collaboration at this scale, and across all aspects of biodiversity information, is essential for effective delivery of important information products such as the Essential Biodiversity Variables and the planned pan-European natural history collections infrastructure, DiSSCo. This presentation explains the goals for this alliance and updates on progress during 2019 in operationalising the concept.

Fossils document the existence of trees and wood-associated organisms from almost 400 million years ago, and today there are between 400,000 and 1 million wood-inhabiting species in the world. This is the first book to synthesise the natural history and conservation needs of wood-inhabiting organisms. Presenting a thorough introduction to biodiversity in decaying wood, the book studies the rich diversity of fungi, insects and vertebrates that depend upon dead wood. It describes the functional diversity of these organisms and their specific habitat requirements in terms of host trees, decay phases, tree dimensions, microhabitats and the surrounding environment. Recognising the threats posed by timber extraction and forest management, the authors also present management options for protecting and maintaining the diversity of these species in forests as well as in agricultural landscapes and urban parks

In the life sciences, there is wide-ranging debate about biodiversity. While nearly everyone is in favor of biodiversity and its conservation, methods for its assessment vary enormously. So what exactly is biodiversity? Most theoretical work on the subject assumes it has something to do with species richness-with the number of species in a particular region-but in reality, it is much more than that. Arguing that we cannot make rational decisions about what it is to be protected without knowing what biodiversity is, James Maclaurin and Kim Sterelny offer in What Is Biodiversity? a theoretical a

This work brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity
