Insufficient Sampling to Identify Species Affected by Turbine Collisions.

The Journal of wildlife management

Beston JA, Diffendorfer JE, Loss S.
PMID: 25914425
J Wildl Manage. 2015 Apr;79(3):513-517. doi: 10.1002/jwmg.852. Epub 2015 Mar 05.

We compared the number of avian species detected and the sampling effort during fatality monitoring at 50 North American wind facilities. Facilities with short intervals between sampling events and high effort detected more species, but many facilities appeared undersampled....

The San Diego Nathan Shock Center: tackling the heterogeneity of aging.

Understanding basic mechanisms of aging holds great promise for developing interventions that prevent or delay many age-related declines and diseases simultaneously to increase human healthspan. However, a major confounding factor in aging research is the heterogeneity of the aging...

Geographic context affects the landscape change and fragmentation caused by wind energy facilities.

PeerJ

Diffendorfer JE, Dorning MA, Keen JR, Kramer LA, Taylor RV.
PMID: 31341727
PeerJ. 2019 Jul 16;7:e7129. doi: 10.7717/peerj.7129. eCollection 2019.

Wind energy generation affects landscapes as new roads, pads, and transmission lines are constructed. Limiting the landscape change from these facilities likely minimizes impacts to biodiversity and sensitive wildlife species. We examined the effects of wind energy facilities' geographic...

A general modeling framework for describing spatially structured population dynamics.

Ecology and evolution

Sample C, Fryxell JM, Bieri JA, Federico P, Earl JE, Wiederholt R, Mattsson BJ, Flockhart DTT, Nicol S, Diffendorfer JE, Thogmartin WE, Erickson RA, Norris DR.

Ecol Evol. 2017 Nov 30;8(1):493-508. doi: 10.1002/ece3.3685. eCollection 2018 Jan.

Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework....

Importance of WNT-dependent signaling for derivation and maintenance of primed pluripotent bovine embryonic stem cells†.

Biology of reproduction

Xiao Y, Amaral TF, Ross PJ, Soto DA, Diffenderfer KE, Pankonin AR, Jeensuk S, Tríbulo P, Hansen PJ.
PMID: 33899086
Biol Reprod. 2021 Jul 02;105(1):52-63. doi: 10.1093/biolre/ioab075.

The WNT signaling system plays an important but paradoxical role in the regulation of pluripotency. In the cow, IWR-1, which inhibits canonical WNT activation and has WNT-independent actions, promotes the derivation of primed pluripotent embryonic stem cells from the...

A continuously updated, geospatially rectified database of utility-scale wind turbines in the United States.

Scientific data

Rand JT, Kramer LA, Garrity CP, Hoen BD, Diffendorfer JE, Hunt HE, Spears M.

Sci Data. 2020 Jan 13;7(1):15. doi: 10.1038/s41597-020-0353-6.

Over 60,000 utility-scale wind turbines are installed in the United States as of October, 2019, representing over 97 gigawatts of electric power capacity; US wind turbine installations continue to grow at a rapid pace. Yet, until April 2018, no...

Nuclear shell structures--the distribution of the quantum states of individual protons and neutrons--provide one of our most important guides for understanding the stability of atomic nuclei. Nuclei with 'magic numbers' of protons and/or neutrons (corresponding to closed shells of...

The expanded level structure of 240Pu available from the present study highlights the role of strong octupole correlations in this nucleus. In addition to a delayed alignment in the yrast band, the observations include the presence of both I(+)-->(I-1)(-)...
