Here, we explore the conceptual and empirical reasons behind choice of extent of study area in such analyses, and offer practical, but conceptually justified, reasoning for such decisions. We assert that the area that has been accessible to the species of interest over relevant time periods represents the ideal area for model development, testing, and comparison.► Use of ecological niche modeling approaches should be grounded in a clear conceptual framework for species’ environmental and geographic distributions. ► The set of areas accessible to the species over relevant periods of its history is termed “M”. ► M is a critical determinant to the outcome of model calibration, model evaluation, and model comparison. ► Estimating M is a complex challenge, and requires further research.

Ethno-biographical accounts narrate their widespread and informed use among various populations and cultures. Knowledge related to their use is specific. Local communities play a crucial role for linking knowledge on characterization of biological resources and conservation, utilization and health-related knowledge

Tra le piante minacciate si trovano specie essenziali per la vita e il sostentamento dell'uomo nelle varie regioni del pianeta. Tra queste troviamo piante utilizzate nell'alimentazione, nella medicina, in pratiche culturali e spirituali. Queste piante a rischio sono necessarie per alleviare la povertà, garantire la sicurezza alimentare, e in questa maniera garantire lo sviluppo sostenibile di molti paesi. Le piante, e le conoscenze bioculturali associate a queste, hanno un ruolo fondamentale nei servizi ecosistemici che supportano tutta la vita sul pianeta terra. Questa dichiarazione non è solo un appello alla comunità internazionale a risolvere la tragica perdita della diversità ...

In most developing nations, significant DAK gaps exist both geographically and taxonomically. This paper explores a novel source of photo-vouchered biodiversity occurrence data, in the form of records associated with photos posted on social networking sites (SNSs). SNSs like Flickr, Facebook, and Picasaweb allow naturalists to share images and associated metadata with other users. I explore the idea of discovering and organizing massive numbers of biodiversity occurrence records now available on SNSs. I present a proof-of-concept with Flickr as the SNS and the Snowy Owl (Bubo scandiacus) and the Monarch Butterfly (Danaus plexippus) as target species, but methods presented here can easily be used for any other SNS, region, or species group, particularly for developing, mega-diverse countries where the need for biodiversity DAK is particularly acute. These approaches are broadly applicable to animal and plant groups that are photographed and that can be identified from photographs with some degree of confidence (e.g., birds, butterflies, cetaceans, orchids, dragonflies, amphibians, plants), and thus offer a rich new source of biodiversity data.
