Data from: Free‐moving artificial eggs containing temperature loggers reveal remarkable within‐clutch variance in incubation temperature

Sydney F. Hope, Sarah E. DuRant, John J. Hallagan, Michelle L. Beck, Robert A. Kennamer & William A. Hopkins
Incubation is a crucial aspect of avian parental care and measuring incubation temperature in the wild can improve our understanding of life history tradeoffs and inform conservation efforts. However, there are challenges associated with measuring the temperature of eggs in natural nests. Most studies to date have measured incubation temperature by using a single, stationary logger in each nest. However, real eggs are rotated and moved throughout the nest by the parent during the incubation...

Data from: Undocumented beetle diversity in the Southeastern United States: a case study of the minute clubbed beetles (Coleoptera: Monotomidae)

Thomas C. McElrath & Joseph V. McHugh
Studies of the saproxylic and predatory beetle family Monotomidae (Coleoptera: Cucujoidea) in the southeastern USA increased the known diversity for the family in the state of Georgia by one genus and nine species. Online records of Monotomidae from Georgia increased from 0 to 885. This work highlights the lack of basic diversity information about small beetles that inhabit wood, leaf litter, and other decaying plant matter in this region.

Data from: Lifespan bias explains live-dead discordance in abundance of two common bivalves

Kelly E. Cronin, Gregory P. Dietl, Patricia H. Kelley & Stewart M. Edie
Lifespan bias potentially alters species abundance in death assemblages through the overrepresentation of short-lived organisms compared to their long-lived counterparts. Although previous work found that lifespan bias did not contribute significantly to live-dead discordance in bivalve assemblages, lifespan bias better explained discordance in two groups: longer-lived bivalve species and species with known lifespans. More studies using local, rather than global, species-wide, lifespans and mortality rates would help to determine the prevalence of lifespan bias, especially...

Data from: Machine learning to classify animal species in camera trap images: applications in ecology

Micheal A. Tabak, Mohammad Sadegh Norouzzadeh, Michael A. Tabak, David W. Wolfson, Steven J. Sweeney, Paul A. Di Salvo, Ryan S. Miller, Jesse S. Lewis, Jeff Clune, Ryan K. Brook, Elizabeth G. Mandeville, Paul M. Lukacs, Anna K. Moeller, Raoul K. Boughton, Bethany Wight, James C. Beasley & Peter E. Schlichting
Motion‐activated cameras (“camera traps”) are increasingly used in ecological and management studies for remotely observing wildlife and are amongst the most powerful tools for wildlife research. However, studies involving camera traps result in millions of images that need to be analysed, typically by visually observing each image, in order to extract data that can be used in ecological analyses. We trained machine learning models using convolutional neural networks with the ResNet‐18 architecture and 3,367,383 images...

Data from: Diet and trophic interactions of a circumglobally significant gelatinous marine zooplankter, Dolioletta gegenbauri (Uljanin, 1884)

Tina L. Walters, Lauren M. Lamboley, Natalia B. Lopez-Figueroa, Aurea E. Rodriguez-Santiago, Deidre M. Gibson & Marc E. Frischer
Gelatinous zooplankton play a crucial role in marine planktonic food webs. However, primarily due to methodological challenges, the in situ diet of zooplankton remains poorly investigated and little is known about their trophic interactions including feeding behavior, prey selection, and in situ feeding rates. This is particularly true for gelatinous zooplankton including the marine pelagic tunicate, Dolioletta gegenbauri. In this study, we applied an 18S rRNA amplicon metabarcoding approach to identify the diet of captive-fed...

Data from: A fast-evolving X-linked duplicate of importin-α2 is overexpressed in sex-ratio drive in Drosophila neotestacea

Kathleen E. Pieper, Robert L. Unckless & Kelly A. Dyer
Selfish genetic elements that manipulate gametogenesis to achieve a transmission advantage are known as meiotic drivers. Sex-ratio X-chromosomes (SR) are meiotic drivers that prevent the maturation of Y-bearing sperm in male carriers to result in the production of mainly female progeny. The spread of an SR chromosome can affect host genetic diversity and genome evolution, and can even cause host extinction if it reaches sufficiently high prevalence. Meiotic drivers have evolved independently many times, though...

Data from: Social living simultaneously increases infection risk and decreases the cost of infection

Vanessa O. Ezenwa, Katherine E.L. Worsley-Tonks & Katherine E. L. Worsley-Tonks
Elevated parasite infection risk is considered to be a near universal cost of social living. However, living in groups may also provide benefits that reduce the negative impacts of infection. These potential ‘tolerance’ benefits of living socially are theoretically possible, but have rarely been described. In this study, we used an anthelmintic treatment experiment in wild Grant’s gazelles (Nanger granti), who are commonly infected with gastrointestinal nematodes (GIN), to show that social living confers both...
