Diversity in warning coloration: selective paradox or the norm?

2019

Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …

The complete mitochondrial genome of the wood tiger moth (Arctia plantaginis) and phylogenetic analyses within Arctiinae

2021

We report the assembly and annotation of the complete mitochondrial genome of the warningly-coloured wood tiger moth (Arctia plantaginis) and investigate its phylogenetic position within Arctiinae. The A.plantaginis mitogenome is 15,479 bp long with 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNA genes, and an A + T-rich region (D-loop). The phylogenetic analyses based on 13 protein-coding genes showed A.plantaginis clustering within a clade of species with white wings and yellow or red bodies. This result can be useful in understanding the evolution of coloration in Arctiid moths. Peer reviewed

Assessing Transfer Entropy in cardiovascular and respiratory time series: A VARFI approach

2021

In the study of complex biomedical systems represented by multivariate stochastic processes, such as the cardiovascular and respiratory systems, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. Recently, the quantification of multiscale complexity based on linear parametric models, incorporating autoregressive coefficients and fractional integration, encompassing short term dynamics and long-range correlations, was extended to multivariate time series. Within this Vector AutoRegressive Fractionally Integrated (VARFI) framework formalized for Gaussian processes, in this work we propose to estimate the Transfer Entropy, or equivalently G…

Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.

2015

Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…

Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…

2021

Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…

Les «Reflexions de la vellesa» d'Anna Murià, un cas singular

2018

L’article consta de dues parts. La primera és un recull exhaustiu d’obres sobre la vellesa al llarg de la història amb la finalitat de comprovar com ha estat considerada en la tradició literària occidental i poder establir paral·lelismes o diferències amb Reflexions de la vellesa. La segona part se centra en el dietari pòstum d’Anna Murià: el fet de reflexionar íntimament sobre l’ancianitat i tot allò que la concerneix, a partir de la pròpia experiència, contribueix a considerar la peça, des d’aquesta perspectiva, com una mostra única.

Platelet cut-off for anticoagulant therapy in thrombocytopenic patients with blood cancer and venous thromboembolism: an expert consensus

2019

Background. Management of venous thromboembolism (VTE) in patients with haematologic malignancies and thrombocytopenia is clinically challenging due to the related risks. No prospective studies or clinical trials have been carried out and, therefore, no solid evidence on this compelling issue is available. Methods. Given this, an expert panel endorsed by the Gruppo Italiano Malattie Ematologiche dell'Adulto Working Party on Thrombosis and Haemostasis was set up to produce a formal consensus, according to the RAND method, in order to issue clinical recommendations about the platelet (PLT) cut-off for safe administration of low molecular weight heparin (LMWH) in thrombocytopenic (PLT <100×…

"Good old Watson! You are the one fixed point in a changing age" : a comparative study of two Finnish translations of Sir Arthur Conan Doyle's The si…

2012

Tämän tutkimuksen päämääränä oli vertailla Sir Arthur Conan Doylen toisesta kokopitkästä Sherlock Holmes romaanista The Sign of the Four poimittuja verbejä ja niiden kahta käännöstä, joista ensimmäinen oli Ida Wickstedtin kääntämä vuodelta 1894, ja toinen Jussi Korhosen käännös vuodelta 2009. Päämääränä oli tutkia, kuinka käännökset eroavat toisistaan, ja pohtia syitä erojen ja samankaltaisuuksien välillä. Tutkimus lähti siitä hypoteesista, että käännösten välillä on suuria eroja, sillä onhan niiden välillä kulunut aikaa yli sata vuotta, ja myös käännösteorioissa on tapahtunut merkittäviä näkökantamuutoksia. Analyysissä verbit jaettiin viiteen eri pääkategoriaan sen mukaan, miten ne vertaut…

Els auxiliars dels temps compostos en català medieval

2005

The study of auxiliary verbs in compound tenses («haver» vs. «Ésser») in Old Catalan is a topic discussed in many works. But no research deeply analysing literary works of the time and using an accurate methodology is available. Our purpose is to show that so significant medieval literary works such as «Llibre de Meravelles» by Ramon Llull, «Llibre dels Fets» by King James I & «Tirant lo Blanch», can also provide very valuable information to understand the phenomenon of change of auxiliary. Referring to usage frequencies, we show that chronology plays a great role in these alternations and outline a whole series of factors that explain the observed evolutive tendencies.
