Data from: Refuges from fire maintain pollinator-plant interaction networks

Opeyemi Adedoja, Carsten F. Dormann, Temitope Kehinde & Michael J. Samways
Fire is a major disturbance factor in many terrestrial ecosystems, leading to landscape transformation in fire‐prone areas. Species in mutualistic interactions are often highly sensitive to disturbances like fire events, but the degree and complexity of their responses are unclear. We use bipartite insect–flower interaction networks across a recently burned landscape to explore how plant–pollinator interaction networks respond to a recent major fire event at the landscape level, and where fire refuges were present. We...

Data from: Pleistocene extinctions as drivers of biogeographical patterns on the easternmost Canary Islands

Carlos Garcia-Verdugo, Juli Caujapé-Castells, Juan Carlos Illera, Mario Mairal, Jairo Patiño, Alfredo Reyes Betancort & Stephan Scholz
Subtropical islands are often viewed as refuges where Quaternary climatic shifts driving global episodes of extinction were buffered. Island biodiversity, however, may have been impacted by climatic fluctuations at local scales, particularly in spatially heterogeneous island systems. In this study, we generated a conceptual framework for predicting the potential impact of Pleistocene extinctions on the biogeographical pattern of the Canarian spermatophyte flora, with a focus on the easternmost Canarian islands (ECI). Then, we performed an...

Data from: Life table invasion models: spatial progression and species-specific partitioning

Zihua Zhao, Cang Hui, Richard E. Plant, Min Su, Tim Carpenter, Nikos Papadopoulos, Zhihong Li & James R. Carey
Biological invasions are increasingly being considered important spatial processes that drive global changes, threatening biodiversity, regional economies, and ecosystem functions. A unifying conceptual model of the invasion dynamics could serve as a useful tool for comparison and classification of invasion processes involving different species across large geographic ranges. By dividing these geographic ranges that are subject to invasions into discrete spatial units we here conceptualize the invasion process as the transition from pristine to invaded...

The evolutionary potential of an insect invader under climate change

Michael Logan, Ingrid Minnaar, Kaitlin Keegan & Susana Clusella-Trullas
Although the impacts of climate change and invasive species are typically studied in isolation, they likely interact to reduce the viability of plant and animal populations. Indeed, invasive species, by definition, have succeeded in areas outside of their native range and may therefore have higher adaptive capacity relative to native species. Nevertheless, the genetic architecture of the thermal niche, which sets a limit to the potential for populations to evolve rapidly under climate change, has...

Data from: Thermal selection as a driver of marine ecological speciation

Peter Teske, Jonathan Sandoval-Castillo, Tirupathi Golla, Arsalan Emami-Khoyi, Mbaye Tine, Sophie Von Der Heyden & Luciano Beheregaray
Intraspecific genetic structure in widely distributed marine species often mirrors the boundaries between temperature-defined bioregions. This suggests that the same thermal gradients that maintain distinct species assemblages also drive the evolution of new biodiversity. Ecological speciation scenarios are often invoked to explain such patterns, but the fact that adaptation is usually only identified when phylogenetic splits are already evident makes it impossible to rule out the alternative scenario of allopatric speciation with subsequent adaptation. We...

Data from: Thermal landscape change as a driver of ectotherm responses to plant invasions

Raquel A. Garcia & Susana Clusella Trullas
A growing body of research demonstrates the impacts of invasive alien plants on native animals, but few studies consider thermal effects as a driver of the responses of native organisms. As invasive alien plants establish and alter the composition and arrangement of plant communities, the thermal landscapes available to ectotherms also change. Our study reviews the research undertaken to date on the thermal effects of alien plant invasions on native reptiles, amphibians, insects and arachnids....

Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial prey

Elena Zvereva, Bastien Castagneyrol, Tatiana Cornelissen, Anders Forsman, Juan Antonio Hernández-Agüero, Tero Klemola, Lucas Paolucci, Vicente Polo, Norma Salinas, K. Jurie Theron, Guorui Xu, Vitali Zverev & Mikhail Kozlov
The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...

Data from: Fine-tuning the nested structure of pollination networks by adaptive interaction switching, biogeography and sampling effect in the Galápagos Islands

Chinenye A. Nnakenyi, Anna Traveset, Ruben Heleno, Henintsoa O. Minoarivelo & Cang Hui
The structure of pollination networks, particularly its nestedness, contains important information on network assemblages. However, there is still limited understanding of the mechanisms underlying nested pollination network structures. Here, we investigate the role of Adaptive Interaction Switching (AIS), island area, isolation, age and sampling effort in explaining the nestedness of pollination networks across ten Galápagos Islands. The AIS algorithm is inspired by Wallace’s elimination of the unfit, where a species constantly replaces its least profitable...

Shuyan Lin, Karl Niklas, Yawen Wan, Dirk Hölscher, Cang Hui, Yulong Ding & Peijian Shi
The data include four comma-delimited (CSV) files and one word document. data1.csv file saves the raw data (including blade fresh mass, dry mass, area, length, width, perimeter and other measures) of 10045 leaves from 101 species, varieties, forms, and cultivars of bamboo; data2.csv file saves the results of the leaf dry mass per unit area (g/m2) comparison among 101 data sets; data3.csv file saves the results of the quotient of blade width to length comparison...

The Bogert effect and environmental heterogeneity

Michael L. Logan, Jenna Van Berkel & Susana Clusella-Trullas
A classic question in evolutionary biology is whether behavioural flexibility hastens or hinders evolutionary change. The latter idea, that behavior reduces the number of environmental states experienced by an organism and therefore buffers that organism against selection, has been dubbed the “Bogert Effect” after Charles Bogert, the biologist who first popularized the phenomenon using data from lizards. The Bogert Effect is pervasive when traits like mean body temperature, which tend to be invariant across space...

Data from: Divergent fire management leads to multiple beneficial outcomes for butterfly conservation in a production mosaic

René Gaigher, James S. Pryke & Michael J. Samways
1. Fire is an intrinsic component of many natural ecosystems. In human-modified landscapes that occur in fire-driven ecosystems, it can be difficult to make fire management decisions, as there must be a trade-off between ideal conservation management and the practicalities of management in an altered landscape. 2. We assess how biodiversity is influenced by differences in fire regime in a landscape fragmented by timber production. Here, optimal fire management for maintaining grassland integrity is not...

Data from: Road avoidance and its energetic consequences for reptiles

James Paterson, James Baxter-Gilbert, Frederic Beaudry, Sue Carstairs, Patricia Chow-Fraser, Christopher Edge, Andrew Lentini, Jacqueline Litzgus, Chantel Markle, Kassie McKeown, Jennifer Moore, Jeanine Refsnider, Julia Riley, Jeremy Rouse, David Seburn, J Zimmerling & Christina Davy
Roads are one of the most widespread human-caused habitat modifications that can increase wildlife mortality rates and alter behaviour. Roads can act as barriers with variable permeability to movement and can increase distances wildlife travel to access habitats. Movement is energetically costly, and avoidance of roads could therefore impact an animal's energy budget. We tested whether reptiles avoid roads or road crossings and explored whether the energetic consequences of road avoidance decreased individual fitness. Using...

Data from: A global meta-analysis of the ecological impacts of alien species on native amphibians

Ana L. Nunes, Jennifer M. Fill, Sarah J. Davies, Marike Louw, Alexander D. Rebelo, Corey J. Thorp, Giovanni Vimercati & G. John Measey
The exponential increase in species introductions during the Anthropocene has brought about a major loss of biodiversity. Amphibians have suffered large declines, with more than 16% considered to be threatened by invasive species. We conducted a global meta-analysis of the impacts of alien species on native amphibians to determine which aspects of amphibian ecology are most affected by plant, invertebrate, fish, amphibian, reptile or mammal introductions. Measures of fitness were most strongly affected; amphibian performance...
