Cultural Symbolism

This book details the natural history and cultural symbolism of a most unusual woodpecker – a species that neither excavates nest holes in trees, nor bores into wood to find insect prey. The elusive Wryneck is best renowned for performing a twisting, writhing head and neck display when threatened, but this ground-breaking study reveals many more secrets of its behaviour and evolution. Detailed information is presented on the species' origins, taxonomy, anatomy, appearance, moult, calls, distribution, conservation status, habitats, movements, breeding, diet and relationships, along with a chapter on its closest relative, the Red-throated Wryneck. The text is richly illustrated throughout with high quality photographs as well as sound spectrograms. This all-encompassing and engaging account has been written for a wide audience, whether professional ornithologist, citizen scientist, amateur birder, woodpecker aficionado and simply someone who wishes to learn more about this curious and remarkable bird.

Study Design: Review. Objectives: Cervical spondylotic myelopathy (CSM) is a major cause of disability, particular in elderly patients. Awareness and understanding of CSM is imperative to facilitate early diagnosis and management. This review article addresses CSM with regard to its epidemiology, anatomical considerations, pathophysiology, clinical manifestations, imaging characteristics, treatment approaches and outcomes, and the cost-effectiveness of surgical options. Methods: The authors performed an extensive review of the peer-reviewed literature addressing the aforementioned objectives. Results: The clinical presentation and natural history of CSM is variable, alternating between quiescent and insidious to stepwise decline or rapid neurological deterioration. For mild CSM, conservative options could be employed with careful observation. However, surgical intervention has shown to be superior for moderate to severe CSM. The success of operative or conservative management of CSM is multifactorial and high-quality studies are lacking. The optimal surgical approach is still under debate, and can vary depending on the number of levels involved, location of the pathology and baseline cervical sagittal alignment. Conclusions: Early recognition and treatment of CSM, before the onset of spinal cord damage, is essential for optimal outcomes. The goal of surgery is to decompress the cord with expansion of the spinal canal, while restoring cervical lordosis, and stabilizing when the risk of cervical kyphosis is high. Further high-quality randomized clinical studies with long-term follow up are still needed to further define the natural history and help predict the ideal surgical strategy.

The Difference

The article is devoted to understanding the features of the implementation of the cultural and educational function in the programs of the television channel «Russia-C». As a rule, coverage of culture and science topics on television channels occurs through programs that capture the difference between trained, «qualified» viewers and a wide audience, and either focus on the former, choosing formats and genres that are not interesting to the majority, or shift the focus to entertainment. In this regard, the resolution of this contradiction and the choice of a format for the TV channel about culture to meet the demand of broad layers of Russian television viewers for high-quality intellectual leisure seems to be significant. The authors of the article analyzed all the Russia-C TV channel programs that are regularly broadcast. The authors identified the features of the programs and concluded that the format of the TV channel is focused on the implementation, first of all, of the cultural and educational function, and also that the programs on TV channels are designed to overcome this contradiction. Competent interlocutors and presenters, who have a flexible strategy and tactics, take part in these programs. The variety of genres and the specifics of camera work are noted, patterns in the design of studios are revealed.

Natural history collections are essential for understanding the world’s biodiversity and drive research in taxonomy, systematics, ecology and biosecurity. One of the biggest challenges faced is the decline of new taxonomists and public interest in collections-based research, which is alarming considering that an estimated 70% of the world’s species are yet to be formally described. Science communication combines public relations with the dissemination of scientific knowledge and offers many benefits to promoting natural history collections to a wide audience. For example, social media has revolutionised the way collections and their staff communicate with the public in real time, and can attract more visitors to collection exhibits and new students interested in natural history. Although not everyone is born a natural science communicator, institutions can encourage and provide training for their staff to become engaging spokespeople skilled in social media and public speaking, including television, radio and/or print media. By embracing science communication, natural history collections can influence their target audiences in a positive and meaningful way, raise the profile of their institution, encourage respect for biodiversity, promote their events and research outputs, seek philanthropic donations, connect with other researchers or industry leaders, and most importantly, inspire the next generation of natural historians.

Extinction risk assessments are increasingly important to many stakeholders (Bennun et al. 2017) but there remain large gaps in our knowledge about the status of many species. The IUCN Red List of Threatened Species (IUCN 2019, hereafter Red List) is the most comprehensive assessment of extinction risk. However, it includes assessments of just 7% of all vascular plants, while 18% of all assessed animals lack sufficient data to assign a conservation status. The wide availability of species occurrence information through digitised natural history collections and aggregators such as the Global Biodiversity Information Facility (GBIF), coupled with machine learning methods, provides an opportunity to fill these gaps in our knowledge. Machine learning approaches have already been proposed to guide conservation assessment efforts (Nic Lughadha et al. 2018), assign a conservation status to species with insufficient data for a full assessment (Bland et al. 2014), and predict the number of threatened species across the world (Pelletier et al. 2018). The wide range in sources of species occurrence records can lead to data quality issues, such as missing, imprecise, or mistaken information. These data quality issues may be compounded in databases that aggregate information from multiple sources: many such records derive from field observations (78% for plant species in GBIF; Meyer et al. 2016) largely unsupported by voucher specimens that would allow confirmation or correction of their identification. Even where voucher specimens do exist, different taxonomic or geographic information can be held for a single collection event represented by duplicate specimens deposited in different natural history collections. Tools are available to help clean species occurrence data, but these cannot deal with problems like specimen misidentification, which previous work (Nic Lughadha et al. 2019) has shown to have a large impact on preliminary assessments of conservation status. Machine learning models based on species occurrence records have been reported to predict with high accuracy the conservation status of species. However, given the black-box nature of some of the better machine learning models, it is unclear how well these accuracies apply beyond the data on which the models were trained. Practices for training machine learning models differ between studies, but more interrogation of these models is required if we are to know how much to trust their predictions. To address these problems, we compare predictions made by a machine learning model when trained on specimen occurrence records that have benefitted from minimal or more thorough cleaning, with those based on records from an expert-curated database. We then explore different techniques to interrogate machine learning models and quantify the uncertainty in their predictions.

Seed-finches are small-sized Neotropical granivorous birds characterized by extremely strong and thick beaks. Among these birds, the Great-billed Seed-Finch Sporophila maximiliani has been selectively and intensively trapped to the extent that has become one of the most endangered bird species in South America, yet its taxonomy remains complex and controversial. Two subspecies have been recognized: S. m. maximiliani (Cabanis, 1851), mainly from the Cerrado of central South America, and S. m. parkesi Olson (= Oryzoborus m. magnirostris), from northeastern South America. Originally, S. m. parkesi was diagnosed as being larger than the Large-billed Seed-Finch, S. c. crassirostris (Gmelin, 1789), but proper comparisons with S. m. maximiliani, which is larger than S. c. crassirostris, were never performed. Here we provide a review of the taxonomic and nomenclatural history of S. maximiliani, reevaluate the validity and taxonomic status of the subspecies based on morphological characters, and significantly revise its geographic distribution. Analyses based on plumage patterns and a Principal Component Analysis of morphometric characters indicated that S. m. parkesi is most appropriately treated as a synonym of the nominate taxon, which results in a monotypic S. maximiliani comprising two disjunct populations. Further, we conducted systematic searches for S. maximiliani in Brazil, in an attempt to obtain natural history information. After more than 6,000 hours of fieldwork in 45 areas of potential and historical occurrence, S. maximiliani was located only in two sites, in marshy environments called veredas, confirming the critical conservation status of this species, at least in Brazil. We discuss the conservation potential for, and the problems involved with, captive breeding of S. maximiliani for reintroduction into the wild.
