An Evaluation of Latent Dirichlet Allocation in the Context of Plant-Pollinator Networks by Liam Callaghan a Thesis Presented To
An evaluation of latent Dirichlet allocation in the context of plant-pollinator networks by Liam Callaghan A Thesis Presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Mathematics and Statistics Guelph, Ontario, Canada c Liam Callaghan, December, 2012 ABSTRACT An evaluation of latent Dirichlet allocation in the context of plant-pollinator networks Liam Callaghan Advisors: University of Guelph, 2012 Dr. A. Ali Dr. G. Umphrey There may be several mechanisms that drive observed interactions between plants and pollinators in an ecosystem, many of which may involve trait matching or trait complementarity. Hence a model of insect species activity on plant species should be represented as a mixture of these linkage rules. Unfortunately, ecologists do not always know how many, or even which, traits are the main contributors to the observed interactions. This thesis proposes the Latent Dirichlet Allocation (LDA) model from artificial intelligence for modelling the observed interactions in an ecosys- tem as a finite mixture of (latent) interaction groups in which plant and pollinator pairs that share common linkage rules are placed in the same interaction group. Sev- eral model selection criteria are explored for estimating how many interaction groups best describe the observed interactions. This thesis also introduces a new model se- lection score called \penalized perplexity". The performance of the model selection criteria, and of LDA in general, are evaluated through a comprehensive simulation study that consider networks of various size along with varying levels of nesting and numbers of interaction groups. Results of the simulation study suggest that LDA works well on networks with mild-to-no nesting, but loses accuracy with increased nestedness. -

Stomach bot flies (Calyptratae: Oestridae, Gasterophilinae) are obligate endoparasitoids of Proboscidea (i.e. elephants), Rhinocerotidae (i.e. rhinos) and Equidae (i.e. horses and zebras, etc.), with their larvae developing in the digestive tract of hosts with very strong host specificity. They represent an extremely unusual diver- sity among dipteran, or even insect parasites in general, and therefore provide sig- nificant insights into the evolution of parasitism. The phylogeny of stomach botflies was reconstructed -

Richard A. Jones. 2010 Crane Park, Twickenham: preliminary invertebrate survey BY RICHARD A. JONES F.R.E.S., F.L.S. 135 Friern Road, East Dulwich, London SE22 0AZ SUMMARY An invertebrate survey of Crane Park in Twickenham was commissioned by the London Borough of Richmond to establish a baseline fauna list. Site visits were made on 12 May, 18 June, 6 and 20 September 2010. Several unusual and scarce insects were found. These included: Agrilus sinuatus, a nationally scarce jewel beetle that breeds in hawthorn Argiope bruennichi, the wasp spider, recently starting to spread in London Dasytes plumbeus, a nationally scarce beetle found in grassy places Ectemnius ruficornis, a nationally scarce wasp which nests in dead timber Elodia ambulatoria, a nationally rare fly thought to be a parasitoid of tineid moths breeding in bracket fungi Eustalomyia hilaris, a nationally rare fly that breeds in wasp burrows in dead timber -

Dörge et al. Parasites Vectors (2020) 13:461 https://doi.org/10.1186/s13071-020-04316-7 Parasites & Vectors RESEARCH Open Access Incompletely observed: niche estimation for six frequent European horsefy species (Diptera, Tabanoidea, Tabanidae) Dorian D. Dörge1*, Sarah Cunze1 and Sven Klimpel1,2 Abstract Background: More than 170 species of tabanids are known in Europe, with many occurring only in limited areas or having become very rare in the last decades. They continue to spread various diseases in animals and are responsible for livestock losses in developing countries. The current monitoring and recording of horsefies is mainly conducted throughout central Europe, with varying degrees of frequency depending on the country. To the detriment of tabanid research, little cooperation exists between western European and Eurasian countries. Methods: For these reasons, we have compiled available sources in order to generate as complete a dataset as possi- ble of six horsefy species common in Europe. We chose Haematopota pluvialis, Chrysops relictus, C. caecutiens, Tabanus bromius, T. bovinus and T. sudeticus as ubiquitous and abundant species within Europe. The aim of this study is to esti- mate the distribution, land cover usage and niches of these species. We used a surface-range envelope (SRE) model in accordance with our hypothesis of an underestimated distribution based on Eurocentric monitoring regimes. Results: Our results show that all six species have a wide range in Eurasia, have a broad climatic niche and can there- fore be considered as widespread generalists. Areas with modelled habitat suitability cover the observed distribution and go far beyond these. This supports our assumption that the current state of tabanid monitoring and the recorded distribution signifcantly underestimates the actual distribution. -

Opisanih je nad 4000 vrst. Mnoge so polifagne. Družina Tephritidae ima kar 500 rodov, ki imajo vsak svoje domorodno območje. Med gospodarsko najpomembnejše rodove spadajo: Anastrepha (domorodne vrste pretežno v Južni in Srednji Ameriki), Bactrocera (Bližnji vzhod in območje Avstralazije), Ceratitis (tropska Afrika) in Rhagoletis (domorodne vrste v zmerno toplem pasu Amerike, Evrope in Azije). Mnoge vrste iz teh rodov so tudi invazivne in povzročajo veliko škodo ob vnosu na nova območja, kar se zaradi mednarodne trgovine dogaja vse pogosteje. Po tej poti so se k nam verjetno vnesle breskova muha (Ceratitis capitata), oljkova muha (Bactrocera oleae), višnjeva muha (Rhagoletis cingulata) in orehova 254 muha (Rh. completa). Od skoraj 200 znanih škodljivih vrst plodovih muh pa jih večina še ni zastopanih v Evropi, zato jih je mogoče obdržati na karantenski listi in predpisati uvozne zahteve za plodove, s katerimi se v EU lahko vnesejo. V prispevku so opisane regulirane vrste plodovih muh v Sloveniji in v Evropski uniji za obdobje 1977 do 2017 in posebnosti pri tem preventivnem ukrepu varstva rastlin. Ključne besede: plodove muhe, Tephritidae, karantenski ukrepi, uvoz, zdravje rastlin ABSTRACT TEMPORARY NATURE OF QUARANTINE PEST CATEGORIES USING THE EXAMPLE OF THE Tephritidae FRUIT FLIES Globally, fruit flies belong to the most significant pests in the production of fruits and vegetables. -
