Late Cretaceous domatia reveals the antiquity of plant–mite mutualisms in flowering plants

S. Augusta Maccracken, Ian Miller & Conrad Labandeira
Mite houses, or acarodomatia, are found on the leaves of over 2,000 living species of flowering plants today. These structures facilitate tri-trophic interactions between the host plant, its fungi or herbivore adversaries, and fungivorous or predaceous mites by providing shelter for the consumers. Previously, the oldest acarodomatia were described on a Cenozoic Era fossil leaf dating to 49 million years in age. Here, we report the first occurrence of Mesozoic Era acarodomatia in the fossil...

Data from: Polyandry and polygyny in a social rodent: an integrative perspective based on social organization, copulations, and genetics

John L. Hoogland, Regina Trott & Stephen R. Keller
Animal mating systems have fascinated biologists for thousands of years. Ways to describe amating systeminclude determining social organization, observing copulations, or using genetics to assign parentage. Social organization can be difficult to quantify, however, documentation of copulations is often challenging, many copulations do not produce offspring, and genetic variation is sometimes minimal. Here we use data from a 7-year study of wild white-tailed prairie dogs (WTPDs, Cynomys leucurus) living in Colorado USA to estimate the...

Data from: Challenges in the conservation of wide-ranging nomadic species

Dejid Nandintsetseg, Chloe Bracis, Kirk A. Olson, Katrin Böhning-Gaese, Justin M. Calabrese, Buyanaa Chimeddorj, William F. Fagan, Christen H. Fleming, Michael Heiner, Petra Kaczensky, Peter Leimgruber, Dalannast Munkhnast, Theresa Stratmann & Thomas Mueller
1. Conservation of nomadic ungulates presents significant conservation challenges because of unpredictability in their movements and space use. Long-term studies on nomadic ungulates offering insights into the variability in space use within and between years are largely missing but are necessary to develop effective conservation strategies. 2. We examined the temporal variability in space-use of 22 Mongolian gazelle, tracked for one to three years with GPS and used the resulting movement patterns to evaluate conservation...

Data from: A phylum-wide survey reveals multiple independent gains of head regeneration in Nemertea

Eduardo Zattara, Fernando Fernández-Álvarez, Terra Hiebert, Alexa Bely & Jon Norenburg
Animals vary widely in their ability to regenerate, suggesting that regenerative ability has a rich evolutionary history. However, our understanding of this history remains limited because regenerative ability has only been evaluated in a tiny fraction of species. Available comparative regeneration studies have identified losses of regenerative ability, yet clear documentation of gains is lacking. We assessed ability to regenerate heads and tails either through our own experiments or from literature reports for 35 species...

Data from: Effects of vertical position on trematode parasitism in larval anurans

Jacob R. Jones, Camille L. Steenrod & John A. Marino
Spatial distributions of animals can affect interactions with their natural enemies, such as parasites, and thus have important implications for host-parasite dynamics. While spatial variation in infection risk has been explored in many systems at the landscape scale, less attention has been paid to spatial structure at smaller scales. Here, we explore a hypothesized relationship between a common spatial variable, vertical position, and risk of parasite infection in a model aquatic system, larval frogs (Rana)...

Contrasting responses to climate change at Himalayan treelines revealed by population demographics of two dominant species

Kumar Mainali, Bharat Shrestha, Ravi Sharma, Arjun Adhikari, Eliezer Gurarie, Michael Singer & Camille Parmesan
Alpine treelines are expected to shift upward due to recent climate change. However, interpretation of changes in montane systems has been problematic because effects of climate change are frequently confounded with those of land use changes. The eastern Himalaya, particularly Langtang National Park, Central Nepal, has been relatively undisturbed for centuries and thus presents an opportunity for studying climate change impacts on alpine treeline uncontaminated by potential confounding factors. We studied two dominant species, Abies...

Data from: The pursuit strategy of predatory bluefish

Matthew McHenry, Jacob Johansen, Alberto Soto, Brian Free, Derek Paley & James Liao
A predator's ability to capture prey depends critically on how it coordinates its approach in response to a prey's motion. Flying insects, bats, and raptors are capable of capturing prey with a strategy known as parallel navigation, which allows a predator to move directly toward the anticipated point of interception. It is unclear if predators using other modes of locomotion are capable of employing this strategy when pursuing evasive prey. Using kinematic measurements and mathematical...
