Red-green opponency in the long visual fibre photoreceptors of brushfoot butterflies (Nymphalidae)

Gregor Belušič, Marko Ilić, Primoz Pirih & Andrej Meglic
In many butterflies, the ancestral trichromatic insect colour vision, based on UV-, blue- and green-sensitive photoreceptors, is extended with red-sensitive cells. Physiological evidence for red receptors has been missing in Nymphalid butterflies, although some species can discriminate red hues well. In eight species from genera Archaeoprepona, Argynnis, Charaxes, Danaus, Melitaea, Morpho, Heliconius and Speyeria we found a novel class of green-sensitive photoreceptors that have hyperpolarising responses to stimulation with red light. These green-positive, red-negative (G+R–)...

Cross-continental comparison of parasite communities in a wide-ranging carnivore suggests associations with prey diversity and host density

Astrid Stronen, Barbara Molnar, Paolo Ciucci, Chris Darimont, Lorenza Grottoli, Paul Paquet, Tim Sallows, Judit Smits & Heather Bryan
Parasites are integral to ecosystem functioning yet often overlooked. Improved understanding of host-parasite associations is important, particularly for wide-ranging species for which host range shifts and climate change could alter host-parasite interactions and their effects on ecosystem function. Among the most widely distributed mammals with diverse diets, grey wolves (Canis lupus) host parasites that are transmitted among canids and via prey species. Grey wolf-parasite associations may therefore influence the population dynamics and ecological functions of...

The awareness, visibility and support for young carers across Europe: a Delphi study

Henk Herman Nap, Renske Hoefman, Nynke De Jong, Lieke Lovink, Ludo Glimmerveen, Feylyn Lewis, Sara Santini, Barbara D’Amen, Marco Socci, Licia Boccaletti, Giulia Casu, Alessandra Manattini, Rosita Brolin, Karina Sirk, Valentina Hlebec, Tatjana Rakar, Tjasa Hudobivnik, Agnes Leu, Fabian Berger, Lennart Magnusson & Elizabeth Hanson
Across Europe, young carers (YCs) and their need for support receive limited attention in the media, policy and empirical research, even though, similar to adult carers, they also provide care to ill family members. The Delphi study, a qualitative research methodology, which provides the focus for this article, had the overall aim of exploring existing successful strategies to support YCs. Compared to YCs, even less is known about adolescent young carers (AYCs), a group that...

Hazelnut SSR database: genetic profiles of the accessions, list of synonyms, and true-to-type genotypes

Paolo Boccacci, Maria Aramini, Matthew Ordidge, Theo Van Hintum, Daniela Torello Marinoni, Nadia Valentini, Jean-Paul Sarraquigne, Anita Solar, Mercè Rovira, Loretta Bacchetta & Roberto Botta
Hazelnut (Corylus avellana L.) is one of the most important tree nut crops in Europe. Germplasm accessions are conserved in ex situ repositories, located in countries where hazelnut production occurs. In this work, we used ten simple sequence repeat (SSR) markers as the basis to establish a core collection representative of the hazelnut genetic diversity conserved in different European collections. A total of 480 accessions were used: 430 from ex situ collections and 50 landraces...

Morphological measurements of six cave and nine surface Asellus aquaticus populations

Gergely Balázs, Anna Biró, Žiga Fišer, Cene Fišer & Gábor Herczeg
The dataset contains data of 17 functional morphological traits measured on 656 individuals from the Asellus aquaticus species complex from six cave and nine surface populations from four countries. The measured traits are covering a wide range of functionalities including locomotion, fecundity and sensing. By including individuals from both sex, and from surface and cave habitats questions concerning troglomorphic adaptation and sexual dimorphism and their interaction can be addressed.

Data from: Disturbance history is a key driver of tree lifespan in temperate primary forests

AIMS We examined differences in lifespan among the dominant tree species (spruce (Picea abies (L.) H. Karst.), fir (Abies alba Mill.), beech (Fagus sylvatica L.), and maple (Acer pseudoplatanus L.)) across primary mountain forests of Europe. We ask how disturbance history, lifetime growth patterns, and environmental factors influence lifespan. LOCATIONS Balkan mountains, Carpathian mountains, Dinaric mountains. METHODS Annual ring widths from 20,600 cores from primary forests were used to estimate tree life spans, growth trends,...

Caterpillar polarisation vision: Histological methods and Rcodes for behavioural analyses

Mizuki Uemura, Andrej Meglič, Myron Zalucki, Andrea Battisti & Gregor Belušič
Processionary caterpillars of Thaumetopoea pityocampa (in Europe) and Ochrogaster lunifer (in Australia) (Lepidoptera: Notodontidae) form single files of larvae crawling head-to-tail when moving to feeding and pupation sites. We investigated if the processions are guided by polarisation vision. The heading orientation of processions could be manipulated with linear polarising filters held above the leading caterpillar. Exposure to changes in the angle of polarisation around the caterpillar resulted in orthogonal changes in heading angles. Anatomical analysis...

Data from: Thermal differences between juveniles and adults increased over time in European forest trees

Maria Mercedes Caron, Florian Zellweger, Kris Verheyen, Lander Baeten, Radim Hédl, Bernhardt-Römermann Markus, Imre Berki, Jörg Brunet, Guillaume Decocq, Sandra Díaz, Thomas Dirnböck, Tomasz Durak, Thilo Heinken, Bogdan Jaroszewicz, Martin Kopecký, Jonathan Lenoir, Martin Macek, Malicki Marek, František Máliš, Thomas Nagel, Michael Perring, Petr Petřík, Kamila Reczyńska, Remigiusz Pielech, Wolfgang Schmidt … & Pieter De Frenne
Woody species’ requirements and environmental sensitivity change from seedlings to adults, a process referred to as ontogenetic shift. Such shifts can be increased by climate change. To assess the changes in the difference of temperature experienced by seedlings and adults in the context of climate change, it is essential to have reliable climatic data over long periods that capture the thermal conditions experienced by the individuals throughout their life cycle. Here we used a unique...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...
