Cannot see the diversity for all the species: evaluating inclusion criteria for local species lists when using abundant citizen science data

Alejandro Ruete, Debora Arlt, Åke Berg, Jonas Knape, Michał Żmihorski & Tomas Pärt
Abundant citizen science data on species occurrences is becoming increasingly available and enables identifying composition of communities occurring at multiple sites with high temporal resolution. However, for species displaying temporary patterns of local occurrences, i.e. that are transient to some sites, biodiversity measures are clearly dependent on the criteria used to include species into local species lists. Using abundant opportunistic citizen science data from frequently visited wetlands we investigated the sensitivity of α- and β-diversity...

Primary data on skull and brain morphology for: Geographical patterns in seasonal changes of body mass, skull, and brain size of common shrews

Javier Lázaro, Lucie Nováková, Moritz Hertel, Jan R. E. Taylor, Marion Muturi, Karol Zub & Dina K. N. Dechmann
Some small mammals exhibit Dehnel’s Phenomenon, a drastic decrease in body mass, braincase and brain size from summer to winter, followed by regrowth in spring. This is accompanied by a reorganization of the brain and changes in other organs. The evolutionary link between these changes and seasonality remains unclear, although the intensity of change varies between locations as the phenomenon is thought to lead to energy savings during winter. Here we explored geographic variation of...

Habitat selection of foraging male Great Snipes on floodplain meadows: importance of proximity to the lek, vegetation cover and bare ground

Michał Korniluk, Paweł Białomyzy, Grzegorz Grygoruk, Łukasz Kozub, Marcin Sielezniew, Piotr Świętochowski, Tomasz Tumiel, Marcin Wereszczuk & Przemysław Chylarecki
Drainage of wetlands and agricultural intensification has resulted in serious biodiversity loss in Europe, not least in grasslands. Consequently, many meadow birds have drastically declined, and the habitats they select for breeding currently rely on land management. However, the selection of habitats maintained by agriculture may contribute to reduced fitness and thus remain maladaptive for individuals, which makes conservation challenging. An understanding of the relationships between species’ habitat selection, food supply and land management in...

Rethinking megafauna

Marcos Moleón, José Sánchez-Zapata, José Donázar, Eloy Revilla, Berta Martín-López, Cayetano Gutiérrez-Cánovas, Wayne Getz, Zebensui Morales-Reyes, Ahimsa Campos-Arceiz, Larry Crowder, Mauro Galetti, Manuela González-Suárez, Fengzhi He, Pedro Jordano, Rebecca Lewison, Robin Naidoo, Norman Owen-Smith, Nuria Selva, Jens-Christian Svenning, José Tella, Christiane Zarfl, Sonja Jähnig, Matt Hayward, Søren Faurby, Nuria García … & Klement Tochner
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are “megafauna”? Here we critically assess the concept of megafauna and propose a goal-oriented framework for megafaunal research. First, we review definitions of megafauna and analyze associated terminology in the scientific literature. Second, we conduct a survey among ecologists and paleontologists to assess the species traits...

Data from: Seed size predicts global effects of small mammal seed predation on plant recruitment

Yvette Ortega, Łukasz Dylewski, Michał Bogdziewicz & Dean Pearson
We conducted a global literature review and meta-analysis to evaluate whether seed size could predict post-dispersal seed predator effects on seed removal and plant recruitment, respectively. Datasets were built using data extracted from published studies focusing on seed predation by small mammals (see Methods for criteria and data extraction protocol). We found that seed size predicted small mammal seed removal rates and their impacts on plant recruitment consistent with optimal foraging theory, with intermediate seed...

Large carnivore expansion in Europe is associated with human population density and land cover changes

Marta Cimatti, Nathan Ranc, Ana Ana Benítez-López, Luigi Maiorano, Luigi Boitani, Francesca Cagnacci, Mirza Čengić, Paolo Ciucci, Mark Huijbregts, Miha Krofel, José López Bao, Nuria Selva, Henrik Andren, Carlos Bautista, Duško Cirovic, Heather Hemmingmoore, Ilka Reinhardt, Miha Marenče, Yorgos Mertzanis, Luca Pedrotti, Igor Trbojević, Andreas Zetterberg, Tomasz Zwijacz-Kozica & Luca Santini
Aim: The recent recovery of large carnivores in Europe has been explained as resulting from a decrease in human persecution driven by widespread rural land abandonment, paralleled by forest cover increase and the consequent increase in availability of shelter and prey. We investigated whether land cover and human population density changes are related to the relative probability of occurrence of three European large carnivores: the grey wolf (Canis lupus), the Eurasian lynx (Lynx lynx) and...

Uninterrupted growth in a non-polar hadrosaur explains the gigantism among duck-billed dinosaurs

Tomasz Szczygielski, Justyna Słowiak, Łucja Fostowicz-Frelik & Michał Ginter
Duck-billed dinosaurs (Hadrosauridae) were the most common ornithopods of the Late Cretaceous. Second only to sauropods and in many cases exceeding the sizes of the largest land mammals (such as indricotheres or proboscideans), they represent the largest terrestrial herbivores that walked the Earth. Despite their gigantic sizes, diversity, and abundance, their growth strategies remain poorly understood. Herein, we examine the bone microstructure of several Mongolian hadrosauroids of varied adult sizes. The small and middle-sized species...

The oxytocin-prostaglandins pathways in the horse (Equus caballus) placenta during pregnancy, physiological parturition, and parturition with fetal membrane retention

Anna Rapacz-Leonard, Mark Leonard, Małgorzata Chmielewska-Krzesińska, Marta Siemieniuch & Tomasz Janowski
Despite their importance in mammalian reproduction, substances in the oxytocin-prostaglandins pathways have not been investigated in the horse placenta during most of pregnancy and parturition. Therefore, we quantified placental content of oxytocin (OXT), oxytocin receptor (OXTR), and prostaglandin E2 and F2 alpha during days 90–240 of pregnancy (PREG), physiological parturition (PHYS), and parturition with fetal membrane retention (FMR) in heavy draft horses (PREG = 13, PHYS = 11, FMR = 10). We also quantified OXTR...

Empirical and methodological challenges to the model-based inference of diversification rates in extinct clades

David Cerny, Daniel Madzia & Graham Slater
Changes in speciation and extinction rates are key to the dynamics of clade diversification, but attempts to infer them from phylogenies of extant species face challenges. Methods capable of synthesizing information from extant and fossil species have yielded novel insights into diversification rate variation through time, but little is known about their behavior when analyzing entirely extinct clades. Here, we use empirical and simulated data to assess how two popular methods, PyRate and Fossil BAMM,...

Identification of determinants of pollen donor fecundity using the hierarchical neighborhood model

Igor Chybicki, Andrzej Oleksa & Monika Dering
Individual differences in male reproductive success drive genetic drift and natural selection, altering genetic variation and phenotypic trait distributions in future generations. Therefore, identifying the determinants of reproductive success is important for understanding the ecology and evolution of plants. Here, based on the spatially-explicit mating model (the neighborhood model), we develop a hierarchical probability model that links co-dominant genotypes of offspring and candidate parents with the phenotypic determinants of male reproductive success. The model accounts...

A fingerprint of climate change across pine forests of Sweden

Jacek Oleksyn, Tomasz Wyka, Roma Żytkowiak, Marcin Zadworny, Joanna Mucha, Monika Dering, Krzysztof Ufnalski, Bengt Nihlgard & Peter Reich
Needle traits of coniferous forests reflect environmental conditions and influence tree physiology and growth. Given the sensitivity of needle traits and tree growth to climate, temperature warming of ≈1°C in the past century may have influenced structure and function of high latitude forests across the globe. Here we show that throughout a ≈1,000 km transect in cold, high latitude Scots pine (Pinus sylvestris L.) forests in Sweden, which has warmed by ≈1°C in a century,...

High variation in last male sperm precedence and genital morphology in the emerald damselfly Lestes sponsa

Frank Johansson, David Berger, Jacob Höglund, Yvonne Meyer-Lucht, Patrik Rödin-Mörch, Szymon Sniegula & Phillip Watts
In organisms where individuals mate multiply, knowledge on the proportion of offspring sired by the last male to mate (P2) under field conditions is important for a thorough understanding of how sexual selection works in nature. In many insect groups, pronounced intraspecific variation in P2 is commonplace. Interestingly, however, in stark contrast to these observations, compilation of P2 data in dragonflies and damselflies (Odonata) indicate that a high P2, seldom below 0.95, is a feature...

Leaf functional traits and insular colonization: subtropical islands as a melting pot of trait diversity in a widespread plant lineage

Carlos Garcia-Verdugo, Pedro Monroy, Francisco I. Pugnaire, Joana Jura-Morawiec, Xoaquín Moreira & Jaume Flexas
Aim: One of the main goals of functional biogeography is to examine distribution patterns of trait diversity, and islands provide excellent study cases for this emerging field. We tested the hypothesis that multiple dispersals from a common mainland pool would promote functional similarity among island systems when environmental conditions are similar, but also novel phenotypic traits related to colonization history and exploitation of new habitats. Location: Mediterranean Basin and Macaronesian islands Methods: We used the...

Heatwave effects on the behavior and life history traits of sedentary antlions

Krzysztof Miler, Daniel Stec & Marcin Czarnoleski
Research on the behavioral responses of animals to extreme weather events, such as heatwaves, is lacking even though their frequency and intensity in nature are increasing. Here, we investigated the behavioral response to a simulated heatwave in two species of antlions (Neuroptera: Myrmeleontidae). These insects spend the majority of their lives as larvae and live in sandy areas suitable for a trap-building hunting strategy. We used larvae of Myrmeleon bore and Euroleon nostras, which are...

Data from: Impact of brood parasitism and predation on nest survival of the fan-tailed gerygone in New Caledonia

Alfredo Attisano, Lara B. Groß, Nozomu J. Sato, Yuji Okahisa, Keita D. Tanaka, Roman Gula, Keisuke Ueda & Jörn Theuerkauf
Predation and brood parasitism are common reasons for nesting failure in passerine species and the additive impact by invasive species is a major conservation concern, particularly on tropical islands. Recognising the relative contribution of the different components of nesting failure rates is important to understand co-evolutionary interactions within brood parasite-host systems. In the remote archipelago of New Caledonia, the fan-tailed gerygone Gerygone flavolateralis is the exclusive host of the brood-parasitic shining bronze-cuckoo Chalcites lucidus. Additionally,...
