The ELFIN mission
Get PDFThe Electron Loss and Fields Investigation with a Spatio-Temporal Ambiguity-Resolving option (ELFIN-STAR, or heretoforth simply: ELFIN) mission comprises two identical 3-Unit (3U) CubeSats on a polar (∼93∘ inclination), nearly circular, low-Earth (∼450 km altitude) orbit. Launched on September 15, 2018, ELFIN is expected to have a >2.5 year lifetime. Its primary science objective is to resolve the mechanism of storm-time relativistic electron precipitation, for which electromagnetic ion cyclotron (EMIC) waves are a prime candidate. From its ionospheric vantage point, ELFIN uses its unique pitch-angle-resolving capability to determine whether measured relativistic electron pitch-angle and energy spectra within the loss cone bear the characteristic signatures of scattering by EMIC waves or whether such scattering may be due to other processes. Pairing identical ELFIN satellites with slowly-variable along-track separation allows disambiguation of spatial and temporal evolution of the precipitation over minutes-to-tens-of-minutes timescales, faster than the orbit period of a single low-altitude satellite (Torbit ∼ 90 min). Each satellite carries an energetic particle detector for electrons (EPDE) that measures 50 keV to 5 MeV electrons with Δ E/E 1 MeV. This broad energy range of precipitation indicates that multiple waves are providing scattering concurrently. Many observed events show significant backscattered fluxes, which in the past were hard to resolve by equatorial spacecraft or non-pitch-angle-resolving ionospheric missions. These observations suggest that the ionosphere plays a significant role in modifying magnetospheric electron fluxes and wave-particle interactions. Routine data captures starting in February 2020 and lasting for at least another year, approximately the remainder of the mission lifetime, are expected to provide a very rich dataset to address questions even beyond the primary mission science objective.Published versio
Elfin is expressed during early heart development
No full textElfin (previously named CLIM1) is a protein that possesses an N-terminal PDZ domain and a C-terminal LIM domain. It belongs to the family of Enigma proteins. Enigma proteins are a family of Cytoplasmic proteins that contain an N-terminal PDZ domain and a series of C-terminal LIM domains. By virtue of these two protein interacting domains, Enigma proteins are capable of protein-protein interactions. It has been proposed that Enigma proteins may act as adapters between kinases and the cytoskeleton. We have previously shown that Elfin is most abundantly expressed in the heart and it colocalizes with α-actinin 2 at the Z-disks of the myocardium. In this report, Elfin was shown to localize at the actin stress fibers of myoblasts, as revealed by green fluorescent protein (GFP) tagging. In situ hybridization and immunostaining showed that Elfin expression begins at an early stage in mouse development and is present throughout the developing heart. Taken together, our experimental results suggest that Elfin may play an important role in myofibrillogenesis and heart development. © 2001 Wiley-Liss, Inc.link_to_subscribed_fulltex
Rare Elfin Abundance Correlates with Host Plant Density

The rare frosted elfin butterfly (Callophrys irus) is a host plant specialist; it lays eggs on only two plant species, including small yellow indigo (Baptisia tinctoria). This makes the butterfly especially vulnerable to habitat fragmentation. Using indigo samples and butterfly survey data, we examined the effect of indigo quantity and quality on elfin abundance at Gavins Pond (Sharon/Foxboro, MA). Indigo density significantly affected butterfly count—frosted elfins were more likely to be spotted in patches with high indigo density. While nutritional analysis is ongoing, current findings suggest that augmenting host plant quantity may help this frosted elfin population

Measuring new growth of kinnikinnick and brown elfin butterfly abundance at the Ma-le’l & Lanphere Dunes: implications for the management of the seaside hoary elfin butterfly
Get PDFThe study assessed changes in inflorescence length of kinnikinnick (Arctostaphylos uva-ursi) new growth and the abundance of brown elfin butterflies (Callophrys augustinas) at the Ma-le’l and Lanphere Dunes. The research took place at the Ma-le’l and Lanphere Dunes in Humboldt County where a surrogate species for the seaside hoary elfin–the brown elfin–is abundant. In the larval stage, the brown elfin feeds on the new growth of kinnikinnick. Our study set out to analyze the food resource availability for brown elfin butterfly larvae, as they are forage on the tender leaves associated with the new growth of kinnikinnick inflorescences. We found a higher abundance of brown elfins was slightly correlated with areas where the average kinnikinnick inflorescence growth rate was higher. Our analysis of several environmental factors in each plot (ant presence, canopy cover, and herbivory) concluded that the variables tested had no significant relationship with the growth of kinnikinnick inflorescences. Future studies should use a longer study interval than the two-week interval used in this study; a longer interval would make it easier to capture changes in the inflorescence length of kinnikinnick. This study has the potential to inform future management strategies that could aid in the recovery of the critically imperiled seaside hoary elfin butterfly, including populations in the Tolowa Dunes State Park in Crescent City, CA

Frosted elfin butterfly Callophrys irus
No full textThe frosted elfin butterfly is endangered in Ohio and is the rarest of all of the elfin species in the state. It can be found in Lucas County; only two sightings have been reported in Hamilton County. This butterfly feeds primarily on lupine Lupinus perennis, which is increasingly rare in the state. It is a member of the Lycaenidae (gossamer winged) family and can be seen between April and May. This species has a wingspan of 1 to 1.25 inches (3.5 to 3.2 cm). In Ohio there are more than 150 species of butterflies. Twenty-seven different species of butterflies representing five families can be found in the Ohio Memory Online Scrapbook, including all seven species of butterflies that are listed as endangered in Ohio. Butterflies are a part of the order Lepidoptera (from the Greek words lepis, which means scale and pteron, which means wing). There are nearly 17,500 species of butterflies world-wide. Approximately 750 of these can be found in North America
