Data from: Scaling up effects of measures mitigating pollinator loss from local- to landscape-level population responsesDavid Kleijn, Theo E. W. Linders, Anthonie Stip, Jacobus C. Biesmeijer, Felix L. Wäckers & Tibor Bukovinszky
1. Declining pollinator populations have caused concern about consequences for food production, and have initiated an increasing number of initiatives that aim to mitigate pollinator loss through enhancement of floral resources. Studies evaluating effects of mitigation measures generally demonstrate positive responses of pollinators to floral resource enhancement. However, it remains unclear whether this represents landscape-level population effects or results from a spatial redistribution of individuals from otherwise unaffected populations. 2. Here we present a method...
Data from: Embryonal life histories: desiccation plasticity and diapause in the Argentinean pearlfish Austrolebias bellottiiTom J.M. Van Dooren, Irma Varela-Lasheras & Tom J. M. Van Dooren
Embryos of annual killifish diapause in soil egg banks while ponds are dry. Their rates of development and survival in different developmental stages determine the numbers and stages of embryos at rewetting. In the Argentinean pearlfish Austrolebias bellottii, we investigated plasticity for desiccation in such embryonal life history components across phases of mild desiccation and rewetting and also effects of life history on hatching. In comparison to non-annuals, our data suggest that incidences of diapause...
Data from: Insular woody daisies (Argyranthemum , Asteraceae) are more resistant to drought-induced hydraulic failure than their herbaceous relativesLarissa C. Doria, Diego S. Podadera, Marcelino Del Arco, Thibaud Chauvin, Erik Smets, Sylvain Delzon & Frederic Lens
1. Insular woodiness refers to the evolutionary transition from herbaceousness towards derived woodiness on (sub)tropical islands, and leads to island floras that have a higher proportion of woody species compared to floras of nearby continents. 2. Several hypotheses have tried to explain insular woodiness since Darwin’s original observations, but experimental evidence why plants became woody on islands is scarce at best. 3. Here, we combine experimental measurements of hydraulic failure in stems (as a proxy...
Data from: Comparative genomics of the nonlegume Parasponia reveals insights into evolution of nitrogen-fixing rhizobium symbiosesRobin Van Velzen, Rens Holmer, Fengjiao Bu, Luuk Rutten, Arjan Van Zeijl, Wei Liu, Luca Santuari, Qingqin Cao, Trupti Sharma, Defeng Shen, Yuda Roswanjaya, Titis A. K. Wardhani, Maryam Seifi Kalhor, Joelle Jansen, D. Johan Van Den Hoogen, Berivan Güngör, Marijke Hartog, Jan Hontelez, Jan Verver, Wei-Cai Yang, Elio Schijlen, Rimi Repin, Menno Schilthuizen, M. Eric Schranz, Renze Heidstra … & Rene Geurts
Nodules harboring nitrogen-fixing rhizobia are a well-known trait of legumes, but nodules also occur in other plant lineages, with rhizobia or the actinomycete Frankia as microsymbiont. It is generally assumed that nodulation evolved independently multiple times. However, molecular-genetic support for this hypothesis is lacking, as the genetic changes underlying nodule evolution remain elusive. We conducted genetic and comparative genomics studies by using Parasponia species (Cannabaceae), the only nonlegumes that can establish nitrogen-fixing nodules with rhizobium....
Data from: Neurocranial anatomy of an enigmatic Early Devonian fish sheds light on early osteichthyan evolutionAlice M. Clement, Benedict King, Sam Giles, Brian Choo, Per Ahlberg, Gavin C. Young, John A. Long & Per E Ahlberg
The skull of ‘Ligulalepis’ from the Early Devonian of Australia (AM-F101607) has significantly expanded our knowledge of early osteichthyan anatomy, but its phylogenetic position has remained uncertain. We herein describe a second skull of ‘Ligulalepis’ and present micro-CT data on both specimens to reveal novel anatomical features, including cranial endocasts. Several features previously considered to link ‘Ligulalepis’ with actinopterygians are now considered generalized osteichthyan characters or of uncertain polarity. The presence of a lateral cranial...
Data from: Thermal limits in native and alien freshwater peracarid Crustacea: the role of habitat use and oxygen limitationWilco C.E.P. Verberk, Rob S.E.W. Leuven, Gerard Van Der Velde & Friederike Gabel
1. In order to predict which species can successfully cope with global warming and how other environmental stressors modulate their vulnerability to climate related environmental factors, an understanding of the ecophysiology underpinning thermal limits is essential for both conservation biology a nd invasion biology. 2. Heat tolerance and the extent to which heat tolerance differed with oxygen availability were examined for four native and four alien freshwater peracarid crustacean species, with differences in habitat use...
