1. Climate warming can alter ecosystem carbon (C) balance and also the composition of soil organic matter (SOM), with important local and global implications. However, the extent to which rising temperature affects SOM composition in permafrost ecosystems remains poorly understood. 2. Here, we experimentally warmed a permafrost ecosystem by open-top chambers (OTCs) on the Tibetan Plateau for four years to quantify the responses of C inputs via vegetation production, C losses via soil respiration, and...

Beyond pairwise interactions: multispecies character displacement in Mexican freshwater fish communities

Andrea J Roth-Monzón, Mark C Belk, J. Jaime Zúñiga-Vega & Jerald B Johnson
Competition has long been recognized as a central force in shaping evolution, particularly through character displacement. Yet research on character displacement is biased as it has focused almost exclusively on pairs of interacting species, while ignoring multispecies interactions. Communities are seldom so simple that only pairs of species interact, and it is not clear if inferences from pairwise interactions are sufficient to explain patterns of phenotypes in nature. Here we test for character displacement in...

Burrowing behavior and burrowing energetics of a bioindicator under human disturbance

Mustafa Gul & Blaine Griffen
Bioindicator species are extensively used for rapid assessment of ecological changes. Their use commonly focuses on changes in population abundance and individual sizes in response to environmental change. These numerical and demographic shifts likely have behavioral and physiological mechanistic drivers that, if understood, could provide additional insights into the use of these species as bioindicators of habitat health. The Atlantic ghost crab, Ocypode quadrata, is a global bio-indicator species of human disturbance on sandy shores....

Data from: The importance of functional responses among competing predators for avian nesting success

Kristen Ellis, Randy Larsen & Dave Koons
1. The relationship between the rate of predation and prey abundance is an important component of predator-prey dynamics. However, functional responses are less straightforward when multiple predators compete for shared prey. Interactions among competing predators can reduce or enhance effects of predation on prey populations. Because many avian populations experience high rates of nest predation, understanding the role of specific predators on nest mortality will lead to more informed conservation and management strategies which attempt...

Data from: Plant uptake offsets silica release from a large Arctic tundra wildfire

Joanna C. Carey, Benjamin W. Abbott & Adrian V. Rocha
Rapid climate change at high latitudes is projected to increase wildfire extent in tundra ecosystems by up to five-fold by the end of the century. Tundra wildfire could alter terrestrial silica (SiO2) cycling by restructuring surface vegetation and by deepening the seasonally-thawed active layer. These changes could influence the availability of silica in terrestrial permafrost ecosystems and alter lateral exports to downstream marine waters, where silica is often a limiting nutrient. In this context, we...

Data from: Loss of biotic resistance and high propagule pressure promote invasive grass-fire cycles

Sam B. St. Clair & Tara B.B. Bishop
1. The spread of invasive grasses across Earth are modifying fire cycles resulting in state changes in arid ecosystems. Disturbance, biotic resistance of native biological communities and propagule pressure, are likely important factors influencing the spread of invasive grasses and their influence on changing fire regimes. 2. Over a five-year period (2011-2016), we tested how the potential loss of biotic resistance of native plant and native rodent communities related to fire and rodent exclusion treatments,...

Data from: Invertebrate community response to fire and rodent activity in the Mojave and Great Basin Deserts

Joshua D. Day, Jackson H. Birrell, Tyson J. Terry, Amy Clark, Phil Allen & Samuel B. St. Clair
Recent increases in the frequency and size of desert wildfires bring into question the impacts of fire on desert invertebrate communities. Furthermore, consumer communities can strongly impact invertebrates through predation and top‐down effects on plant community assembly. We experimentally applied burn and rodent exclusion treatments in a full factorial design at sites in both the Mojave and Great Basin deserts to examine the impact that fire and rodent consumers have on invertebrate communities. Pitfall traps...

Data from: Phylogenomics reveals the evolutionary timing and pattern of butterflies and moths

Akito Y. Kawahara, David Plotkin, Marianne Espeland, Karen Meusemann, Emmanuel F. A. Toussaint, Alexander Donath, France Gimnich, Paul B. Frandsen, Andreas Zwick, Mario Dos Reis, Jesse R. Barber, Ralph S. Peters, Shanlin Liu, Xin Zhou, Christoph Mayer, Lars Podsiadlowski, Caroline Storer, Jayne E. Yack, Bernhard Misof & Jesse W. Breinholt
Butterflies and moths (Lepidoptera) are one of the major super-radiations of insects, comprising nearly 160,000 described extant species. As herbivores, pollinators, and prey, Lepidoptera play a fundamental role in almost every terrestrial ecosystem. Lepidoptera are also indicators of environmental change and serve as model organisms for research on mimicry and genetics. They have been central to the development of co-evolutionary hypotheses, such as butterflies with flowering plants, and moths' evolutionary arms race with echolocating bats....

Data from: Higher-level phylogeny and reclassification of Lampyridae (Coleoptera: Elateroidea)

Gavin Martin, Kathrin Stanger-Hall, Marc Branham, Luiz Da Silveira, Sarah Lower, David Hall, Xue-Yan Li, Alan Lemmon, Emily Lemmon & Seth Bybee
Fireflies (Lampyridae) are a diverse family of beetles which exhibit an array of morphologies including varying antennal and photic organ morphologies. Due in part to their morphological diversity, the classification within the Lampyridae has long been in flux. Here we use an anchored hybrid enrichment approach to reconstruct the most extensive molecular phylogeny of Lampyridae to date (436 loci and 98 taxa) and to evaluate firefly higher-level classification. We propose several classification changes supported by...

Data from: Forest Giants on Different Evolutionary Branches: Ecomorphological Convergence in Helicopter Damselflies

Emmanuel F. A. Toussaint, Seth M. Bybee, Robert J. Erickson & Fabien L. Condamine
The convergent evolution of analogous features is an evolutionary process occurring independently across the tree of life. From the evolution of echolocation, prehensile tail, viviparity or winged flight, environmental factors often drive this astonishing phenomenon. However, convergent evolution is not always conspicuous or easily identified. Giant damselflies count among the largest flying insects on Earth, and have astonishing ecologies including orb-web spider plucking and oviposition in phytotelmata. One species occurs in the Afrotropics and 18...

Data from: Parallel Miocene dispersal events explain the cosmopolitan distribution of the Hypogymnioid lichens

Pradeep K. Divakar, Xin-Li Wei, Bruce McCune, Paloma Cubas, Carlos D. Boluda, Steven G. Leavitt, H. Ana Crespo, Svetlana Tchabanenko & H. Thorsten Lumbsch
Aim: Contemporary species’ distributions are shaped by both geography and historical events, such as extinction, diversification in specific areas and long-distance dispersals. In the most diverse family of lichen-forming fungi, Parmeliaceae, the Hypogymnioid clade, is an example of an evolutionary lineage comprised of species occurring in temperate to subpolar regions in both hemispheres. Here, we elucidate the timing of diversification events and the impact of historical events on the species distribution in this lineage. Location:...
