Growth hormone pulses are differentially regulated by the circadian clock gene Bmal1

Erica Schoeller, Karen Tonsfeldt, McKenna Sinkovich, Ruijing Shi & Pamela Mellon
In this study, we found that loss of the circadian clock gene Bmal1 causes disruptions throughout the growth hormone (GH) axis, from hepatic gene expression to production of urinary pheromones and pheromone-dependent behavior. First, we show that Bmal1 knockout (KO) males elicit reduced aggressive responses from WT males and secrete lower levels of major urinary proteins (MUPs); however, we also found that a liver-specific KO of Bmal1 (Liver-Bmal1-KO) produces a similar reduction in MUP secretion...

Response diversity in corals: hidden differences in bleaching mortality among cryptic Pocillopora species

Scott Burgess, Erika Johnston, Alex Wyatt, James Leichter & Peter Edmunds
Variation among functionally similar species in their response to environmental stress buffers ecosystems from changing states. Functionally similar species may often be cryptic species representing evolutionarily distinct genetic lineages that are morphologically indistinguishable. However, the extent to which cryptic species differ in their response to stress, and could therefore provide a source of response diversity, remains unclear because they are often not identified or are assumed to be ecologically equivalent. Here, we uncover differences in...

Amplicon sequence variant tables of Donax gouldii microbiomes from Scripps Pier, La Jolla, CA, USA

Alexander Neu
Predicting how populations and communities of organisms will respond to anthropogenic change is of paramount concern in ecology today. For communities of microorganisms, however, these predictions remain challenging, primarily due to data limitations. Information about long-term dynamics of host-associated microbial communities, in particular, are lacking. In this study, we use well-preserved and freshly collected samples of soft tissue from a marine bivalve host, Donax gouldii, at a single site to quantify the diversity and composition...

Data from: Chimpanzees behave prosocially in a group-specific manner

Edwin J. C. Van Leeuwen, Sarah E. DeTroy, Stephan P. Kaufhold, Clara Dubois, Sebastian Schütte, Josep Call & Daniel B. M. Haun
Chimpanzees act cooperatively in the wild, but whether they afford benefits to others, and whether their tendency to act prosocially varies across communities is unclear. Here, we show that chimpanzees from neighboring communities provide valuable resources to group members at personal cost, and that the magnitude of their prosocial behavior is group specific. Provided with a resource-donation experiment allowing for free (partner) choice, we observed an increase in prosocial acts across the study period in...

Heterogeneity in the Dynamic Effects of Uncertainty on Investment

Sungje Byun & Soojin Jo
How does aggregate profit uncertainty influence investment activity at the firm level? We propose a parsimonious adaptation of a factor-autoregressive conditional heteroscedasticity model to exploit information in a subindustry sales panel for an efficient and tractable estimation of aggregate volatility. The resulting uncertainty measure is then included in an investment forecasting model interacted with firm-specific coefficients. We find that higher profit uncertainty induces firms to lower capital expenditure on average, yet to a considerably different...

Gorilla herpes simplexvirus phylogenetic analysis

Joel Wertheim
Viruses closely related to human pathogens can reveal the origins of human infectious diseases. Human herpes simplexvirus type 1 (HSV-1) and type 2 (HSV-2) are hypothesized to have arisen via host-virus co-divergence and cross-species transmission. We report the discovery of novel herpes simplexviruses during a large-scale screening of fecal samples from wild gorillas, bonobos, and chimpanzees. Phylogenetic analysis indicates that, contrary to expectation, simplexviruses from these African apes are all more closely related to HSV-2...

Triennial migration and philopatry in the critically endangered soupfin shark (Galeorhinus galeus)

Andrew Nosal, Daniel Cartamil, Arnold Ammann, Lyall Bellquist, Noah Ben-Aderet, Kayla Blincow, Echelle Burns, Eric Chapman, Ryan Freedman, Peter Klimley, Ryan Logan, Christopher Lowe, Brice Semmens, Connor White & Philip Hastings
Globally, one-quarter of shark and ray species is threatened with extinction due to overfishing. Effective conservation and management can facilitate population recoveries; however, these efforts depend on robust data on movement patterns and stock structure, which are lacking for many threatened species, including the Critically Endangered soupfin shark (Galeorhinus galeus), a circumglobal coastal-pelagic species. Using passive acoustic telemetry, we continuously tracked 34 mature female soupfin sharks, surgically implanted with coded acoustic transmitters, for seven years...

Impact of Helicoverpa zea salivary GOX on stomatal conductance and volatile emission of host plants

Po-An Lin, Yintong Chen, Duverney Chaverra-Rodriguez, Chan Chin Heu, Nursyafiqi Bin Zainuddin, Jagdeep Singh Sidhu, Michelle Peiffer, Ching-Wen Tan, Anjel Helms, Donghun Kim, Jared Ali, Jason Rasgon, Jonathan Lynch, Charles Anderson & Gary Felton
This data set contain raw data associated with the manuscript titled "Silencing the alarm: An insect salivary enzyme closes plant stomata and inhibits volatile release". Herbivore-induced plant volatiles (HIPVs) are widely recognized as ecologically important to plant. While the majority of studies focused on the induction of this “cry for help”, little is known about whether insect herbivores have evolved mechanisms to reduce the release of HIPVs. Here we show that a caterpillar (Helicoverpa zea)...
