A rare 300 kilometer dispersal by an adult male white-tailed deer

Remington Moll
Despite the key roles that dispersal plays in individual animal fitness and meta-population gene flow, it remains one of the least understood behaviors in many species. In large mammalian herbivores, dispersals might span long distances and thereby influence landscape-level ecological processes, such as infectious disease spread. Here we describe and analyze an exceptional long-distance dispersal by an adult white-tailed deer (Odocoileus virginianus) in the central United States. We also conducted a literature survey to compare...

Natural 15N abundance of bulk soil N, ammonium, and nitrate in soil profiles

Geshere Abdisa Gurmesa, Erik A Hobbie, Shasha Zhang, Ang Wang, Feifei Zhu, Weixing Zhu, Keisuke Koba, Muneoki Yoh, Chuankuan Wang, Qiuliang Zhang & Yunting Fang
Assessment of nitrogen (N) saturation of forests is critical to evaluate how ecosystems will respond to current and future global changes such as N deposition. However, quantifying N saturation remains a challenge. We developed a conceptual model of N saturation stages in forest ecosystems based on i) a hypothetical relative rate of ammonification, nitrification, and denitrification, ii) concentrations of ammonium and nitrate in the soil, and iii) 15N enrichment pattern of bulk soil N, ammonium,...

Genomic data reveal the biogeographic and demographic history of Ammospiza sparrows in northeast tidal marshes

Jennifer Walsh, Adrienne Kovach, Phred Benham, Gemma Clucas, Virginia Winder & Irby Lovette
Aim: Shaped by both climate change and sea-level rise, tidal salt marshes represent ephemeral systems that are home to only a few, highly specialized species. The dynamic ecological histories and spatial complexities of these habitats, however, render it challenging to reconstruct the complete biogeographic histories of their endemic taxa. Here, we leverage three species of North American Ammospiza sparrows that inhabit tidal marshes ( Ammospiza caudacuta, A. maritima, and A. n. subvirgatus) and closely related...

Data from: Evolution of flexible biting in hyperdiverse parasitoid wasps

Thomas Van De Kamp, István Mikó, Arnold H. Staniczek, Benjamin Eggs, Daria Bajerlein, Tomáš Faragó, Lea Hagelstein, Elias Hamann, Rebecca Spiecker, Tilo Baumbach, Petr Janšta & Lars Krogmann
One key event in insect evolution was the development of mandibles with two joints, which allowed powerful biting, but restricted their movement to a single degree of freedom. These mandibles define the Dicondylia, which constitute over 99 percent of all extant insect species. It was common doctrine that the dicondylic articulation of chewing mandibles remained unaltered for more than 400 million years. We report highly modified mandibles overcoming the restrictions of a single degree of...

Functional, temporal, and spatial complementarity in mammal-fungal spore networks enhances mycorrhizal dispersal following forest harvesting

Ryan Stephens, Serita Frey, Anthony D'Amato & Rebecca Rowe
Animals that disperse plant or fungal propagules following forest disturbances, including timber harvests, play an important role during forest regeneration by dispersing seeds or spores from intact communities to disturbed sites. Determining how complementary or redundant animal species are as dispersers of propagules is key to understanding the stability of dispersal dynamics and informing management practices. Here we examine the functional, temporal, and spatial components of mycorrhizal fungal spore dispersal by small mammals (rodents and...

Sperm length divergence as a potential pre-zygotic barrier in a passerine hybrid zone

Emily Cramer, Gaute Grønstøl, Logan Maxwell, Adrienne Kovach & Jan Lifjeld
The saltmarsh sparrow Ammospiza caudacuta and the Nelson’s sparrow A. nelsoni differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap. In this advanced hybrid zone, past inter-breeding and current back-crossing result in substantial genomic introgression in both directions, although few hybrids are currently produced in most locations. However, because both species are non-territorial and have only brief male-female interactions, it is difficult to determine to what extent assortative...

Data from: Botany is the root and the future of invasion biology

Nicholas Kooyers, Brittany Sutherland, Craig Barrett, James Beck, Michael McKain, Maribeth Latvis & Erin Sigel
This dataset was used to create Figure 1 within the linked On the Nature of Things article. The article describes how botanists have historically contributed to the field of invasion biology and why botanists should be an important contributor in the coming years. To make this point, we compared the relative frequencies of google ngrams containing the words 'invasive species', 'invasive plants', or the sum of frequencies from several different animal taxa including: ‘invasive insects’,...

Data From: Prevalence and risk factors of Anaplasma infections in eastern moose (Alces alces americana) and winter ticks (Dermacentor albipictus) in Maine, United States

James Elliott, Caroline Dickson, Kantar Lee, Matthew O'Neal, Anne Lichtenwalner, Ann Bryant, Walter Jakubas, Peter Pekins, Sandra De Urioste-Stone & Pauline Kamath
Eastern moose (Alces alces americana) are heavily parasitized by winter ticks (Dermacentor albipictus), the dominant cause of increased calf mortality in the northeastern United States. Although much work has focused on the direct negative effects of winter tick on moose, it remains unknown whether diseases transmitted by ticks may also affect moose health, or pose a risk to other species. In this study, we explored the role that moose and winter ticks play in transmission...

Retention fraction of 15N-labelled deposited ammonium and nitrate in forests

Geshere Abdisa Gurmesa, Ang Wang, Shanlong Li, Shushi Peng, Wim De Vries, Per Gundersen, Philippe Ciais, Oliver L Phillips, Erik Hobbie, Weixing Zhu, Knute Nadelhoffer, Yi Xi, Edith Bai, Tao Sun, Dexiang Chen, Wenjun Zhou, Yiping Zhang, Yingrong Guo, Jiaojun Zhu, Lei Duan, Dejun Li, Keisuke Koba, Enzai Du, Guoyi Zhou, Xingguo Han … & Yunting Fang
The impacts of enhanced nitrogen (N) deposition on global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

Mammals on mountainsides revisited: trait-based tests of assembly reveal the importance of abiotic filters

Brooks Kohli, Richard Stevens, Eric Rickart & Rebecca Rowe
Aim: Mountains provide uniquely informative systems for examining how biodiversity is distributed and identifying the causes of those patterns. Elevational patterns of species richness are well-documented for many taxa but comparatively few studies have investigated patterns in multiple dimensions of biodiversity along mountainsides, which can reveal the underlying processes at play. Here, we use trait-based diversity patterns to determine the role of abiotic filters and competition in the assembly of communities of small mammals across...

Respirometry data for cactus mice (Peromyscus eremicus) corresponding to Colella et al. 2021

Jocelyn Colella, Danielle Blumstein & Matthew MacManes
Metabolism is a complex phenotype shaped by natural environmental rhythms, as well as behavioral, morphological, and physiological adaptations. Metabolism has been historically studied under constant environmental conditions, but new methods of continuous metabolic phenotyping now offer a window into organismal responses to dynamic environments, and enable identification of abiotic controls and the timing of physiological responses relative to environmental change. We use indirect calorimetry to characterize metabolic phenotypes of the desert-adapted cactus mouse (Peromyscus eremicus)...
