Leading trait dimensions in flood-tolerant plants

Yingji Pan, Ellen Cieraad, Jean Armstrong, William Armstrong, Beverley Clarkson, Ole Pedersen, Eric Visser, Laurentius Voesenek & Peter Van Bodegom
Background and Aims While trait-based approaches have provided critical insights into general plant functioning, we lack a comprehensive quantitative view on plant strategies in flooded conditions. Plants adapted to flooded conditions have specific traits (e.g. root porosity, low root/shoot ratio and shoot elongation) to cope with the environmental stressors including anoxic sediments, and the subsequent presence of phytotoxic compounds. In flooded habitats, plants also respond to potential nutrient and light limitations, e.g. through the expression...

The shape of aroma: X-ray CT scans of citrus fruits, their separate tissues, and their individual oil glands

Erik Amezquita, Michelle Quigley, Tim Ophelders, Danelle Seymour, Elizabeth Munch & Daniel Chitwood
From preventing scurvy to being part of religious rituals, citrus are intrinsically connected to human health and perception. From tiny mandarins to head-sized pummelos, citrus capability of hybridization provides a vastly diverse array of fruit sizes and shapes, which in turn corresponds to a diversity of flavors and aromas. These sensory qualities are tightly linked to oil glands in the citrus skin. The oil glands are also key to understanding fruit development, and the essential...

Integrated population model for the Mallard in the Netherlands

, Eelke Jongejans, Chris A. M. Van Turnhout, Loes Van Den Bremer, Henk Van Der Jeugd & Erik Kleyheeg
Europe’s highest densities of breeding Mallards (Anas platyrhynchos) are found in the Netherlands, but the breeding population there has declined by ~30% since the 1990s. The exact cause of this decline has remained unclear. Here, we used an integrated population model to jointly analyze Mallard population survey, nest survey, duckling survival and band-recovery data. We used this approach to holistically estimate all relevant vital rates, including duckling survival rates for years for which no explicit...

Acoustic recordings and corresponding mammal, bird, human activity, vegetation, and climate data from a tropical forest landscape

Johan Diepstraten, Jacques Kuemo Kuenbou & Jacob Willie
Obtaining and analysing sound data can be a tedious and lengthy process. We present sound data consisting of 38,065 1-minute sound recordings obtained in three sites within a rainforest landscape in southeast Cameroon. The sites differ in anthropogenic disturbance. We also present meta data corresponding to 20,485 of these recordings with the identification of all animal vocalisations in each 1-minute sound recording. Additionally, we provide a raw database with data on habitat, human activities, remoteness,...

High-density genomic characterization of native Croatian sheep breeds

Ivana Drzaic, Ino Curik, Boris Lukic, Mario Shihabi, Meng-Hua Li, Juha Kantanen, Salvatore Mastrangelo, Elena Ciani, Johannes A. Lenstra & Vlatka Cubric-Curik
A recent comprehensive genomic analysis based on 50K SNP profiles has shown that the regional Balkan sheep populations have considerable genetic overlap but are distinctly different from surrounding breeds. All eight Croatian sheep breeds were represented by a small number of individuals per breed. Here, we genotyped 220 individuals representing the native Croatian sheep breeds (Istrian Sheep, Krk Island Sheep, Cres Island Sheep, Rab Island Sheep, Lika Pramenka, Pag Island Sheep, Dalmatian Pramenka, Dubrovnik Sheep)...

Grazing and global change factors differentially affect biodiversity-ecosystem functioning relationships in grassland ecosystems

Miao He, Yuhan Pan, Guiyao Zhou, Kathryn Barry, Yuling Fu & Xuhui Zhou
Grazing and global change (e.g., warming, nitrogen deposition and altered precipitation) both contribute to biodiversity loss and alter ecosystem structure and functioning. However, how grazing and global change interactively influence plant diversity, ecosystem productivity, and their relationship remains unclear at the global scale. Here, we synthesized 73 field studies to quantify the individual and/or interactive effects of grazing and global change factors on biodiversity-productivity relationship in grasslands. Our results showed that grazing significantly reduced plant...

Data from: Gradual warming prior to the end-Permian mass extinction

Jana Gliwa, Michael Wiedenbeck, Martin Schobben, Clemens Vinzenz Ullmann, Wolfgang Kiessling, Abbas Ghaderi, Ulrich Struck & Dieter Korn
The biggest known mass extinction in the history of animal life occurred at the Permian-Triassic boundary and has often been linked to global warming. Previous studies suggested that a geologically rapid (less than 40 kyr) temperature increase of more than 10°C occurred simultaneously with the main extinction pulse. This hypothesis is challenged by geochemical and palaeontological data indicating profound environmental perturbations and a temperature rise prior to the main extinction. Using Secondary Ion Mass Spectrometry...

Considering inner and outer bark as distinctive tissues helps to disentangle the effects of bark traits on decomposition

Li Lin, Li Lin, Yao-Bin Song, Yikang Li, Leo Goudzwaard, Richard S.P. Van Logtestijn, Chenhui Chang, Rob Broekman, Jurgen Van Hal, Juan Zuo, Frank J. Sterck, Lourens Poorter, Ute Sass-Klaassen, Mariet M. Hefting & J. Hans C. Cornelissen
Revealing the ecological consequences of bark multifunctionality and its underlying traits has become a relatively new but essential focus in plant ecology. Although the enormous differences between the most crucial bark layers, i.e., inner and outer bark, in structure and functions have been widely recognized, the overall bark has been regarded as a homogenous tissue in most bark-related studies. This has led to poor knowledge on the functional independence, specialized contributions and possible linkages of...

Data from: Group-specific expressions of co-feeding tolerance in bonobos and chimpanzees preclude dichotomous species generalizations

Edwin J. C. Van Leeuwen, Nicky Staes, Stephanie Kordon, Jake Brooker, Suska Nolte, Zanna Clay, Marcel Eens & Jeroen M. G. Stevens
The human species exhibits a remarkable level of social tolerance which has propelled a plethora of behavioural expressions pivotal to our biological success. To date, the evolutionary origins of humans’ “ultra-sociality” remain unclear, despite a substantial research focus on our closest living evolutionary relatives, the great apes. Bonobos are typically portrayed as more socially tolerant than chimpanzees and consequentially (sometimes) presented as a better model to study the evolutionary roots of human sociality. Yet, the...

Data from: Functionally diverse tree stands reduce herbaceous diversity and productivity via canopy packing

Liting Zheng, Y. H. Han Chen, Yann Hautier, Difeng Bao, Mingshan Xu, Baiyu Yang, Zhao Zhao, Li Zhang & Enrong Yan
1. There is extensive experimental evidence for the importance of biodiversity in sustaining ecosystem functioning. However, such experiments typically prevent immigration by continuously removing non-target species, thereby questioning the generality of these findings to real-world ecosystems. This is particularly true in forest ecosystems where understorey herbaceous species are key biodiversity components but are usually weeded in tree diversity experiments. Consequently, little is known about how tree diversity influences the natural dynamics of understorey herbaceous layers....

Data from: Testosterone eliminates strategic prosocial behavior

Hana Kutlikova, Lei Zhang, Jack Van Honk & Claus Lamm
Humans are strategically more prosocial when their actions are being watched than when they act alone. Using a psychopharmacogenetic approach, we investigated the computational and endocrinological mechanisms of such audience-driven prosociality. 187 participants received either a single dose of testosterone or a placebo and performed a prosocial and self-oriented reinforcement learning task. Crucially, the task was performed either in private or when being watched. Rival theories of testosterone's role in status-seeking suggest that the hormone...

Functional niche constraints on carnivore assemblages (mammalia: carnivora) in the Americas: What facilitates coexistence through space and time?

Andrés Arias-Alzate, Felber J. Arroyave, Oscar Y. Romero Goyeneche, Rafael Hurtado Heredia, José F. Gonzalez-Maya, Joaquín Arroyo-Cabrales, A. Townsend Peterson & Enrique Martínez-Meyer
Aim: Mammalian carnivores are among the best studied groups in terms of evolutionary history. However, the effects of species interactions in shaping community assemblages remain poorly understood. We hypothesize that indirect interactions via ecological trait filtering play a key role in structuring carnivoran assemblages, mediate coexistence, and thus should show high functional diversity in space and time at continental scales. Location: Americas. Taxon: Mammalian carnivores (Mammalia: Carnivora). Methods: We followed a macroecological perspective via ecological...

GPS vertical time series of solid Earth deformation for the southern Antarctic Peninsula 2010-2020

Achraf Koulali, Pippa Whitehouse, Peter Clarke, Michiel van den Broeke, Grace Nield, Matt King, Michael Bentley, Bert Wouters & Terry Wilson
This dataset contains vertical GPS time series observed from selected sites in the southern Antarctic Peninsula. The dataset contains raw time series and time series corrected for the effect of elastic deformation - induced from the RACMO surface mass balance (SMB) model with a 5.5 km horizontal resolution (van Wessem et al. 2018). Hence there are two time series files for each of ten sites, presented as CSV files. There is a README file which...

Accelerating ice loss from peripheral glaciers in North Greenland

Shfaqat Abbas Khan, William Colgan, Thomas A. Neumann, Michiel R. Van Den Broeke, Kelly M. Brunt, Brice Noël, Jonathan L. Bamber, Javed Hassan & Anders A. Bjørk
In recent decades, Greenland’s peripheral glaciers have experienced large-scale mass loss, resulting in a substantial contribution to sea-level rise. Only 4% of Greenland’s ice cover are small peripheral glaciers that are distinct from the ice sheet proper. Despite comprising this relatively small area, these small peripheral glaciers are responsible for 11% of the ice loss associated with Greenland’s recent sea-level rise contribution. Using the satellite laser platforms ICESat and ICESat-2, we estimate that ice loss...

Intra- and interspecific variability of specific leaf area mitigate the reduction of community stability in response to warming and nitrogen addition

Mengjiao Huang, Shaopeng Wang, Xiang Liu, Ming Nie, Shurong Zhou & Yann Hautier
Global environmental changes are reducing the diversity and affecting the functioning of natural ecosystems as well as their ability to reliably provide ecosystem functions and services to mankind. Many studies have shown that a greater plant diversity can stabilize community productivity against environmental fluctuations. However, most of these studies focused on plant species richness, thus overlooking the potential role of functional traits in stabilizing community productivity against environmental fluctuations. Whether and how functional trait mean...

Circum-Arctic distribution of chemical anti-herbivore compounds arctic shrubs

Elin Lindén, Mariska Te Beest, Ilka Abreu, Thomas Moritz, Maja Sundqvist, Isabel C Barrio, Julia Boike, John Bryant, Kari Anne Bråthen, Agata Buchwal, Guillermo Bueno, Alain Cuerrier, Dagmar Egelkraut, Bruce Forbes, Martin Hallinger, Monique Heijmans, Luise Hermanutz, David S Hik, Annika Hofgaard, Milena Holmgren, Diane C Huebner, Toke Hoye, Ingibjörg Jónsdóttir, Elina Kaarlejärvi, Emilie Kissler … & Johan Olofsson
Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top-down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the circum-Arctic variation in defence compounds is explained by taxa or defence functional groups (resinous/non-resinous). We measured circum-Arctic...

The generality of cryptic dietary niche differences in diverse large-herbivore assemblages

Robert Pringle, Johan Pansu, Matthew Hutchinson, T. Michael Anderson, Mariska Te Beest, Colleen Begg, Keith Begg, Aurelie Bonin, Lackson Chama, Simon Chamaillé-Jammes, Eric Coissac, Joris Cromsigt, Margaret Demmel, Jason Donaldson, Jennifer Guyton, Christina Hansen, Christopher Imakando, Azwad Iqbal, Davis Kalima, Graham Kerley, Samson Kurukura, Marietjie Landman, Ryan Long, Isaack Munuo, Ciara Nutter … & Tyler Kartzinel
Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth-forms but are agnostic towards food-plant species identity. Empirical support for these models is variable, suggesting that additional mechanisms of resource partitioning may be important in sustaining large-herbivore diversity in African savannas. We used DNA metabarcoding to conduct a taxonomically...

The ProkaBioDen database, a global database of benthic prokaryotic biomasses and densities in the marine realm

Tanja Stratmann
Benthic prokaryotes include Bacteria and Archaea and dominate densities of marine benthos. They play major roles in element cycles and heterotrophic, chemoautotrophic, and phototrophic carbon production. To understand how anthropogenic disturbances and climate change might affect these processes, better estimates of prokaryotic biomasses and densities are required. Hence, I developed the ProkaBioDen database, the largest open-access database of benthic prokaryotic biomasses and densities in marine surface sediments. In total, the database comprises 1,089 georeferenced benthic...

Greenland mass trends from airborne and satellite altimetry during 2011–2020

Shfaqat Abbas Khan, Jonathan L. Bamber, Eric Rignot, Veit Helm, Andy Aschwanden, David M. Holland, Michiel R. Van Den Broeke, Michalea King, Brice Noël, Martin Truffer, Angelika Humbert, William Colgan, Saurabh Vijay & Peter Kuipers Munneke
We use satellite and airborne altimetry to estimate annual mass changes of the Greenland Ice Sheet. We estimate ice loss corresponding to a sea-level rise of 6.9±0.4 millimeters from April 2011 to April 2020, with the highest annual ice loss rate of 1.4 mm/yr sea-level equivalent from April 2019 to April 2020. On a regional scale, our annual mass loss timeseries reveals 10-15 m/yr dynamic thickening at the terminus of Jakobshavn Isbræ from April 2016...

Data from: Chimpanzee communities differ in their inter- and intrasexual social relationships

Bruce Rawlings, Edwin J. C. Van Leeuwen & Marina Davila-Ross
Male and female human social bonding strategies are both culturally and genetically shaped. Chimpanzees, our phylogenetically joint closest living relatives, exhibit complex social structures and show impressive cultural diversity. Whether chimpanzee male and female bonding patterns are culturally shaped remains unclear. Studies of wild chimpanzees bonding across sex show that in some communities males show strong bonds with other males, whereas in others females form particularly strong intra-sex bonds. This suggests that there may be...
