Biogeography of oribatid mites (Acari) reflects their ancient origin and points to Southeast Asia as centre of radiation

AbstractAimUnderstanding the worldwide distribution of species has fascinated scientists at least since Alfred Russel Wallace. Global patterns of belowground biodiversity may fundamentally differ from those of aboveground organisms. Here, we examine the global pattern and potential mechanisms driving the endemism and overlap of a soil microarthropod taxon.LocationGlobal.TaxonOribatida, Acari.MethodsWe investigated the global distribution of oribatid mites in five biogeographic regions including North America, South America, Eurasia, Africa and Oceania using a world list on the distribution of ~11,400 described species (including subspecies) at species, genera and family levels.Results and Main ConclusionWe found that most “endemic” (i.e., only occurring in one of the regions) species (4297) and also genera (143) occurred in Eurasia indicating that this region was the centre of radiation of oribatid mites. Within Eurasia, oribatid mite diversity was highest in Southeast Asia (1975 species) likely reflecting the long tropical history of this region (at least 200 million years), and also high fluctuations in water levels and island formation on the Sunda Shield. On a family level, oribatid mite diversity did not differ between biogeographic regions indicating that oribatid mites are much older than the tropics and older than the existence of Pangaea supporting the view of their origin in the early Palaeozoic. Finally, among the 55 species that occurred in all biogeographic regions nearly 50% reproduce by thelytoky and colonize high latitude ecosystems, indicating that compared to sexual species a disproportionally high number of parthenogenetic species is distributed worldwide suggesting that they possess a general‐purpose genotype. The other ~50% sexuals predominantly occur in tropical/subtropical regions across biogeographic regions supporting the view that resource shortage in tropical regions favours sex. Our findings highlight the importance of biogeographical studies of soil animals to better understand their diversity, distribution and life history strategies.

Taxonomy and systematics of the Neotropical primates: a review and update

The database of the IUCN SSC Primate Specialist Group currently (December 2023) registers 218 species and subspecies of Neotropical primates in 24 genera and five families. In the early 1960s, the diversity of Neotropical primates was estimated to be around 200 species and subspecies. From then, through the 1970s to the mid-1990s, however, the perception of the region’s primate diversity dropped, and reached an all-time low at 83 species and subspecies in 1980 (A World List of Mammalian Species, G. B. Corbet and J. E. Hill, British Museum (Natural History), Comstock Publishing, Cornell University Press, London and Ithaca). Interest in taxonomy and primate field research in the Neotropics was subdued up to the late 1970s. Change was sparked by the burgeoning capture of primates for biomedical research in the 1950s and 1960s, and the increasing destruction of the Amazon rainforests from the late 1970s. The numbers increased, at first slowly, but then, in 1995, they leapt back to the 200s in anticipation of a book by C. P. Groves (2001, Primate Taxonomy, Smithsonian Institution Press, Washington, DC). The species’ counts (not including subspecies) rose due to the adoption of the Phylogenetic Species Concept over the Biological Species Concept, the former favoring the category of species over subspecies. In this article, we discuss the changes in species and subspecies numbers in the classification of the Neotropical primates, and report on the taxonomic changes resulting from taxonomic research ongoing since 2012. We emphasize the importance of taxonomic research for an understanding of the diversity of primates, and for conservation planning, not least in identifying the populations that are threatened.

How can universities & colleges stand high in world ranking?

The world ranking of universities has assumed great significance because those that rank high are found to produce globally competent professional and political leaders needed to adeptly manage the affairs of a country from local to international levels. World experience tells us that in the knowledge-based economy of today, the prosperity of a nation is essentially driven by leadership shown in research and innovation, which typically flourishes in world-class universities. Having world-class universities in a nation is now a prerequisite to qualify for achieving developed nation status. Even if a nation is endowed with abundant natural resources, without world-class universities, it cannot become developed and remains a developing country. There are many universities in India that have a good amount of money and excellent infrastructure, yet they do not rank high on the world list. They have all the required resources at hand except for good professors. Unfortunately, in India, faculty growth is neglected. Outdated rules and regulations and service conditions have constrained professors, preventing them from performing to the best of their abilities. This is the main bottleneck. Their service conditions urgently need to be reengineered along the lines of the world's best universities, without which India is less likely to rank high globally and, in turn, become a developed country, as is eagerly desired. Each university and college should have a mission and ambition to build its faculty to a world-class level.

Analysis of the Skewed Sex Ratio and Female Foeticide in India

The present study is aimed at drawing attention and concern of the readers towards nefarious female foeticide problem in India. Female Foeticide is the death sentence to a girl even before her birth. The objectives of the study are met by analysing the problem of female foeticide by studying skewed sex ratio and child sex ratio in India and its states. The primary causes of female foeticide are addressed along with its adverse consequences on society. Study on the status of sex ratio in countries of world lists India at 4rth rank in most skewed sex ratio. Although sex ratio has improved recently yet child sex ratio is still the worst in India. The Northern Indian states & union territories have lowest sex ratio. The rural areas with less literacy have more sex ratio than urban areas with higher literacy. Indian government has taken many initiatives to promote girl child birth and enacted a number of laws to curb female foeticide, yet the immoral female foeticide is still in practice. Present study also suggests some measures to prevent this malpractice and hence empower the Women.

Bir kültürel miras turizmi destinasyonunun yaşam döngüsü: Boğazkale Örneği

The life course of the destination is critical in sustainable tourism which includes many dimensions. The life course of destinations, which begins with the exploration phase, continues towards the decline process for various reasons. Continuing the life course of the destination, postponing the decline phase, or rejuvenating a destination that is in the decline phase depends on determining the stage of tourism development of the destinations and what kind of development course they follow. This study aims to determine the applicability of Boğazkale, where is essential destination for cultural heritage tourism for Butler's (1980) Tourism Area’s Life Cycle model and on the UNESCO Cultural Heritage List and the Memory of the World List. Single-case study design was used, and semi-structured interviews were conducted to determine which life stage Boğazkale destination was within the scope of Butler's (1980) TALC model. Exploratory and explanatory case analysis was used for the findings. As a result, it has been determined that Boğazkale's destination is in the “decline stage.”

Textual heritage and digital archives - the case of the Hyakugo Archive in Kyoto.

What are the effects and significance of inscribing an archive or group of documents in a heritage list? In light of the positive effects of digital technology on archival science, should all archives and past documents be considered "heritage," or are some more significant than others? What are the implications and benefits of a heritage archive? Is creating a digital database of a specific archive considered part of heritage conservation? Is the term "heritagization" or "heritage making" a synonym for preservation or conservation? In this article, I will attempt to answer some of these questions from the point of view of premodern literature, drawing on recent researches in heritage studies, specifically in the subfield of "critical heritage studies. After briefly introducing the current state of heritage scholarship, I will present the definition of "textual heritage" that I developed during my most recent project. Secondly, to reflect on how the concept of textual heritage can affect our understanding of historical archives, I will present the case of the Hyakugo Archive of Toji Temple (Kyoto, Japan), a collection of 19,000 documents dating from the eight to the eighteenth century, which was inscribed on the UNESCO Memory of the World List in 2005 and has been fully digitized and made available to the public via the Internet. I will examine a particular historical event that occurred during the 17th century, which can be viewed as a re-birth of this archive as a cultural heritage and reflect on the implications of this event for the survival of the archive itself and its use today.

Pesticides and cognitive impairment in older adults: evidence from southern Colombia

AbstractBackgroundEnvironmental exposure to specific chemical groups of pesticides (Carbamates, Organophosphates, Pyrethroids, and Organochlorines), as well as the non or inadequate use of personal protective equipment during pest management, have been associated to cognitive decline and increased risk of dementia (Hayden et al., 2010). This study investigated cognitive functioning in older adults exposed to pesticides in southern Colombia.MethodsA sample of 353 older adults was recruited. Of these, 279 had not been exposed to pesticides (n‐Exp) and 74 had (Exp). They were matched according to age [n‐Ex: 63.80 (3.25), Ex: 63.30 (6.96), t = 0.618, p = 0.538] and years of education [n‐Ex: 9.29 (6.28), Ex: 8.95(6.35), t = 0.418, p = 0.676]. They were assessed with a battery of cognitive tests including CERAD (Aguirre‐Acevedo et al., 2016), The Addenbrooke’s Cognitive Examination (ACE‐R), the Free and Cued Selective Reminding Test (FCSRT) and questionnaires.ResultsFDR corrected comparisons revealed overall lower cognitive abilities in the Exp group (ACE‐R, q = 0.027). They also displayed Memory (FCSRT, q = 0.020; World List Learning q = 0.014) and Constructional Praxis (q = 0.007) impairments. Of those exposed, 73% reported no use of personal protective equipment, and neither the participants nor their family members reported concerns about cognitive decline [Self‐reported: n‐Exp: 14.27 (7.44), Exp: 14.92 (7.98), t = ‐0.654, p = 0.513; Family‐reported: n‐Exp: 10.43 (7.12), Exp: 10.26 (7.45), t = ‐0.182, p = 0.856].ConclusionOlder adults from southern Colombia who have been exposed to pesticides show significant cognitive impairments, which have gone unnoticed by both the affected individuals and their family. Cognitive abilities found to be affected have been associated with risk of dementia caused by Alzheimer’s Disease or Parkinson’s Disease (FCSRT and Constructional Praxis). These types of dementia have been previously associated with this environmental risk factor (Chin‐Chan et al., 2015). More awareness about environmental factors and actions to mitigate their risk are urgently needed, and should be considered by future recommendations (e.g., Livingston et al., 2020).Aguirre‐Acevedo et al. (2016). Int. Psychogeriatr, 28(3), 503‐510. https://doi.org/S1041610215001660.Chin‐Chan et al. (2015).

33 Title: Examining memory performances in a sample of cognitively healthy illiterate older adult population in India

Objective:Despite the rise in literacy, 773 million of the global population is estimated to be illiterate. The rate of illiteracy is even higher among women and older adults (OA). Literacy has been well documented to impact cognitive skills, and most neuropsychological tests developed are for individuals with higher education. Moreover, there is sparse research on cognitive process and performance of illiterate individuals across cognitive domains.Per a 2011 census, the illiteracy rate in the Indian older adult population was as high as 56%, and within this group, women and older adults in rural regions were especially vulnerable. Thus, it is important to understand cognitive performance of illiterate Indian older adult population, especially when they are being assessed for neurodegenerative disorders.Participants and Methods:This study used subset of data from Harmonized Longitudinal Aging Study of India, Diagnostic Assessment of Dementia (LASI DAD), which was developed by the Gateway to Global Aging Data. A sample of cognitive healthy OA (n = 715) was selected based on Hindi Mental Status Exam score of >19 and a Clinical Dementia Rating Scale of 0 (literate = 419, illiterate = 296). Given the heterogeneity of the population, adapted cognitive instruments were used. This study compared memory performances, using word list and constructional praxis with delayed recall tasks, of OA based on their literacy status (illiterate vs. literate).Results:Literate cognitive healthy OA (M = 15.27, SD = 3.9) learned more words over three trials than illiterate OA (M = 12.17, SD = 3.7) on a world list task, a statistically significant difference (M = 3.1, 95% CI [2.5, 3.6], t (713) = 10.62, p<0.05. Literate OA (M = 8.7, SD = 2.2) had higher scores on task of copy of simple geometrical figures than illiterate OA (M = 5.3, SD = 2.8), a statistically significant difference (M = 3.3, 95% CI [2.9, 3.7], t (713) = 7.1, p<0.05. Literate OA (M = 4.5, SD = 1.8) also recalled more words than illiterate OA (M = 3.6, SD = 2.1) after a delay. Recall of geometric figures after a delay was higher for literate OA (M = 5, SD = 2.9) as well compared to illiterate OA (M = 2.4, SD = 2.5).Conclusions:Conclusion: In a sample of cognitively healthy Indian older adults, literate OA consistently performed better than illiterate OA on both verbal and nonverbal memory measures. This is consistent with past literature which shows that illiterate individuals take longer to learn verbal information and have lower recall. Additionally, use of geometric figure may be complicated for these individuals. These are important considerations when assessing an OA for memory problems with low or no education. Next steps would be to look at differences across other cognitive domains and also examining if cognitive differences exist in illiterate OA based on gender.

THE COMPETITIVE APPROACH VS THE HUMANIST-SOCIAL APPROACH IN QUALITY MANAGEMENT OF POSTGRADUATE STUDIES

Postgraduate quality management can be carried out from two approaches: the first, (competitive) is based on compliance with academic, scientific and administrative standards, and the positioning of universities in world lists of best institutions; the second (humanist-social) in the commitment of the universities with the solution of the problems of sustainable development. The objective of this article is to review the recent information backing the competitive and social-humanist approaches to quality in postgraduate studies, and on this basis support what should be the meeting point between both approaches in Latin American universities. For this purpose, articles published predominantly in Latin America, and also from Asia and Africa, were analyzed. From the points of view expressed in the reviewed documents, reflections on quality management in postgraduate studies were formulated from the Latin American perspective. It was found that the competitive approach predominates in postgraduate quality management worldwide, and that the social responsibility of universities, and of postgraduate studies in particular, implies a commitment to solving local, regional and national problems, only achievable with a solid social-humanist approach. Latin American universities must combine compliance with competitive standards with postgraduate social responsibility objectives, and assign greater weight to the latter in accreditation systems.

A Single Measure of Overall Export Performance

Exports are a lifeline to a country’s growth, and an overall index can describe its export performance. However, there is little evidence of a single measure encompassing all the relevant aspects of exports. A composite and multi-dimensional measure can aid in assessing the relative position of a country in the world list and identifies necessary policy interventions. The article proposes an Overall Export Performance Index that satisfies the principles of index formation—monotonicity, time reversal, robustness and an unbiased approach. The proposed index avoids selecting weights and scaling variables. It facilitates the identification of crucial indicators requiring the attention of policymakers, tracking the progress of a country across time and the computing of mean and variance of the index for a group of countries at a given time. An empirical comparison of the USA and India reveals that India registered better overall export performance than the USA from 2015 to 2018. The results suggest India’s need for reforms in existing foreign trade policies. JEL Codes: F1, F10, F13

Etymological compendium of cycad names

The meanings of some cycad names are self-explanatory, but many others are not. This compendium provides the etymological derivations of the names of all currently accepted cycad genera, species, and infraspecific taxa, with their authorities and dates and pages of publication. It is meant to complement the World List of Cycads, and as such, it will be periodically updated following changes in taxonomy and nomenclature.

Extrafloral nectaries of an Atlantic Forest conservation area in Southeastern Brazil

Although extrafloral nectaries (EFNs) are reported as extremely important to understand ecological interactions, the diversity of EFN-bearing plants remains underappreciated. In Brazil, studies are concentrated in Cerrado and extremely poorly known in other phytogeographic domains, such as Atlantic forest. Thus, this study provides one of the first checklists of angiosperms with EFNs in a protected area of the Brazilian Atlantic forest, bringing information about the richness, location of EFNs on the plant’s organs, as well as plant’s habit and conservation status. A total of 93 EFN-bearing species belonging to 61 genera and 29 families is reported, which corresponds to 16.5 % of the local flora. The vast majority has not been evaluated for their conservation status, and twenty species are endemic to the Brazilian Atlantic forest. Vines and trees are the predominant plant habits and EFNs are mostly found on leaves. More than half of the species (53.7 %) comprises new additions to the world list of EFN-bearing plants, including the first record in Dilleniaceae. Our findings show a large number of EFN-bearing plant species from a single and small protected area in the Brazilian Atlantic forest. It reinforces the lack of studies of this nature, where further investigations are strongly recommended.

Productive vocabulary knowledge of pre-service teachers as a predictor of writing performance: basis for English syllabi And instructional modules improvement

Although a growing body of research has indicated that writing performance is determined by the writer’s level of vocabulary knowledge, the relationship between the two still needs to be validated as it has strong pedagogical implication. This study aimed at investigating the productive vocabulary knowledge of pre-service teachers as a predictor of writing performance which serves as basis for English syllabi and instructional modules improvement. Seventy-seven (77) students from different year levels were assessed on their productive vocabulary knowledge using vocabulary profiler along four frequency levels:  1st 1,000 words of high frequency, 2nd 1, 000 words least frequently used, Academic World List (AWL), and Off-list. They were also evaluated on their writing performance in terms of organization, content and mechanics. The study found that the productive vocabulary knowledge of the pre-service teachers was limited to the levels with high frequency words. Findings also indicate that their writing performance (good) was affected by their productive vocabulary test performance. Furthermore, the productive vocabulary knowledge of students was the same regardless of sex, age and year level. Meanwhile, except for sex variations were observed in writing performance along age and year level.  

Indigenous knowledge interaction network between host plants and edible insects in the Ecuadorian Amazon

Globally, nearly two billion people consume approximately 2,111 species of insects, 92% of which are harvested directly from their natural ecosystems. However, intensifying insect harvesting causes ecological alterations and biodiversity loss. In the Ecuadorian Amazon, the Kichwa people are the primary consumers of insects. Thus, this study characterised the diversity of edible insects, host plants, and cultural significance among two peri-urban Kichwa communities. We used photo-elicitation, free-listing, semi-structured interviews, andin situ walk-in-the-woods to identify relevant edible insects. Then, we used species accumulation curves, the Salience Smith Index (SSI), ecological interaction networks, and extinction models to assess insect-host species interactions and cultural significance. We registered 19 edible insect species from three orders and six families. Furthermore, we reported two new species for the world list of edible insects and one for the Ecuadorian list. Ten insect species were associated with 21 host plant species. The interaction between theRhynchophorus palmarum beetle and theBactris gasipaes palm tree had the highest cultural significance (SSI>0.18,P<0.05). Furthermore, we found that 30% of the insect species and 52% of the host plant species (of which 90% were palms) were essential for conserving the interaction network structure. Finally, the extinction models suggested that host plant species knowledge was intrinsically related to edible insect knowledge conservation. Our findings provide basic ecological and cultural information for developing edible insect breeding projects and safeguarding traditional knowledge.

International Standardized Nomenclature for Outbred Stocks of Laboratory Animals.

In accordance with the «Aims of ICLA» (ICLA Bulletin No. 26, March 1970) the Governing Board established in 1969 a Working Party to prepare an International Nomenclature System for Outbred Animals. The members were: Professor, Dr. A. Spiegel, Federal Republic of Germany, chairman.Dr. M. Festing, United KingdomDr. K. Kondo, JapanDr. R. Loosli, SwitzerlandMr. S. Poiley, U.S.A. The nomenclature rules, completed and approved by the ICLA Governing Board on 8 December 1971, are published herewith. I am convinced that this system will bring order out of the existing chaos. The system is an offer to the world laboratory animal science, particularly the breeders and users. Editors of scientific journals, catalogues, and indices all over the world are also encouraged to require and use animal stock identification by this system for outbred animals used in experimentation. The ICLA Governing Board would have preferred to have seen an international centralization of symbol registration. However, the ICLA Secretariat has not got the capacity necessary for such a task and some practical solution to the registration problem will have to be found by the Governing Board. A final aim should then be for ICLA to publish a comprehensive world list of breeder symbols at intervals. Oslo, January 1972 Stian Erichsen Secretary-General.

Developing a sustainable cultural heritage information system

PurposeThe purpose of this paper is to emphasize the need for developing an Indian cultural heritage information system (CHIS) where the cultural heritages can efficiently document, manage and preserve and integrate with a searchable user interface mechanism. Further, the study scopes out the feasibility of developing single-window comprehensive national CHIS for all the cultural heritage properties of India enlisted in the United Nations Educational, Scientific and Cultural Organization (UNESCO’s) World Heritage list.Design/methodology/approachConservation efforts and their sustenance require the support of a knowledge base cum digital archiving and information retrieval tool. The present study identifies the basic requirements, strategies and the execution of designing a reliable information system for cultural heritage inheritances to safeguard them to facilitate access to the current and future resilient communities. Approach on issues and challenges associated while developing such an information system has also been addressed with possible recommendations.FindingsIn India, even though regional level conservation efforts are occurring, no comprehensive information system, which gives the whole perspective of the item or environment of heritage site, has been developed for the heritage sites recognized by UNESCO in its World Heritage list from India. Developing such a comprehensive digital archive for cultural heritage helps to showcase its assets and ensures its visibility globally without hampering the physical form. Application Information and Communication Technology and digital technologies can extensively be used coupled with mechanisms such as mobile devices, digital systems and content visualization techniques to support the efficient and effective management in a systemized way.Research limitations/implicationsAs a pilot study, this paper examined the cultural heritage properties incorporated in the UNESCO World list. There are many lesser-known and unprotected cultural heritages in different parts of the country having artistic value and the unique characteristics, and the possibility of building the similar kind of information system for them with innovative technological solutions are not covered under this study.Practical implicationsAccess to such an exclusive digital archive in a single-window platform would greatly support administrators, tourist departments, culture departments, development administration and conservation activists. The digital version of cultural inheritances created under the cultural heritage of India must have relevance to different subject fields such as history, archeology, manuscript logy, art, administration, knowledge management, computer science and library science. Also, it ensures that the resources remain accessible to the public without any restrictions provided with a comprehensive recapitulation.Originality/valueTo the authors’ best knowledge, no such comprehensive system envisages or is practiced in the country. Developing such a system with technological and data infrastructure also helps to understand the value, support the activities related to cultural heritage and bring the local community to support and initiate such heritage conservation activities.

Tweeting on dementia: A snapshot of the content and sentiment of tweets associated with dementia

This study aimed to record and characterise tweets related to dementia, to investigate their content and sentiment. Data were extracted from Twitter over a period of six weeks during February and March 2019 and then analysed using Linguistic Inquiry and Word Count (LIWC) and AntWordProfiler. Using five search terms related to dementia, this study collected 860,383 tweets (more than 27 million words). Results have shown that out of all the collected tweets, 48.63 percent of tweets related to the search term ‘dementia’, 49.95 percent to ‘Alzheimer’s disease’ and the remainder related to frontotemporal dementia, Lewy Body dementia and vascular dementia. People wrote more positively and personally about the term ‘dementia’ than the other terms, and more technically regarding the term ‘Alzheimer’s disease’. All search terms had a negative emotional tone overall. Dementia and related terms are commonly discussed on Twitter. The overall negative emotional tone associated with all dementia related search terms suggests that dementia is still largely stigmatised and talked about negatively. Recommendations for future research include the development of a health world list or a dementia world list, and to consider how the results of this research inform social change interventions going forwards.

In (deficit) schizophrenia, a general cognitive decline partly mediates the effects of neuro-immune and neuro-oxidative toxicity on the symptomatome and quality of life.

Schizophrenia and deficit schizophrenia are accompanied by neurocognitive impairments. The aim of this study was to examine whether a general factor underpins impairments in key Cambridge Neuropsychological Test Automated Battery (CANTAB) probes, verbal fluency test (VFT), world list memory (WLM), True Recall, and mini mental state examination (MMSE). We recruited 80 patients with schizophrenia and 40 healthy controls. All patients were assessed using CANTAB tests, namely paired-association learning, rapid visual information processing, spatial working memory, one touch stockings of Cambridge, intra/extradimensional set-shifting (IED), and emotional recognition test. We found that a general factor, which is essentially unidimensional, underlies those CANTAB, VFT, WLM, True Recall, and MMSE scores. This common factor shows excellent psychometric properties and fits a reflective model and, therefore, reflects a general cognitive decline (G-CoDe) comprising deficits in semantic and episodic memory, recall, executive functions, strategy use, rule acquisition, visual sustained attention, attentional set-shifting, and emotional recognition. Partial least squares analysis showed that 40.5% of the variance in G-CoDe is explained by C-C motif ligand 11, IgA to tryptophan catabolites, and increased oxidative toxicity, and that G-CoDe explains 44.8% of the variance in a general factor extracted from psychosis, hostility, excitation, mannerism, negative symptoms, formal thought disorders, and psychomotor retardation, and 40.9% in quality-of-life scores. The G-CoDe is significantly greater in deficit than in nondeficit schizophrenia. A common core shared by a multitude of neurocognitive impairments (G-CoDe) mediates the effects of neurotoxic pathways on the phenome of (deficit) schizophrenia.

Khöömii, World Lists, and the Question of Representation

Based on an ethnomusicological approach, including literature with media sources and a self-reflective approach, this article describes the sociopolitical issues related to the practices of khöömii in Mongolia, the regions of Inner Mongolia, Xinjiang (China), and Tyva (Russia). Through different narratives, it explores and analyzes the inscription of khöömii by UNESCO but also traces the historical path by which khöömii was spectacularized and institutionalized, two steps that contributed to the establishment of khöömii as a National Heritage and then as an Intangible Cultural Heritage. The author argues that khöömii has always sparked competition and questions about representation, whether on the political UNESCO's list or as a popular Guinness world record.

Further vocal evidence for treating the Bahama Nuthatch Sitta (pusilla) insularis as a species

The case for recognising Bahama Nuthatch Sitta insularis as a species separate from Brown-headed Nuthatch S. pusilla has been made several times since 2004, based on plumage, morphometrics, voice and genetic distance, but only one of four world lists currently accepts it as such. We assembled three new sets of recordings and recently published evidence on playback responses. We found that S. insularis has at least five vocalisations that are homologous to but always much higher pitched (by 2–3 kHz) than those of S. pusilla, such that the main calls of the latter are strikingly different from those of the former, and playback studies all suggest a consistently weak response in one species to the calls of the other. Moreover, genetic divergence of insularis from mainland pusilla is greater than that of another Bahamian taxon, Bahama Warbler Setophaga flavescens, recently accepted by all world lists as a species, from mainland Yellow-throated Warbler S. dominica. Taken together with the notably larger bill of Sitta insularis, these factors reinforce the case for treating Bahama Nuthatch as a (regrettably now almost certainly extinct) species.
