Conceptual model of salt marsh management on Merritt Island National Wildlife Refuge, Florida: final report

Diking and holding water on salt marshes ("impounding" the marsh) is a management technique used on Merritt Island National Wildlife Refuge (MINWR) and elsewhere in the Southeast to: a) prevent the reproduction of saltmarsh mosquitos, and b) attract wintertering waterfowl and other marsh, shore, and wading birds. Because of concern that diking and holding water may interfere with the production of estuarine fish and shellfish, impoundment managers are being asked to consider altering management protocol to reduce or eliminate any such negative influence. How to change protocol and preserve effective mosquito control and wildlife management is a decision of great complexity because: a) the relationships between estuarine organisms and the fringing salt marshes at the land-water interface are complex, and b) impounded marshes are currently good habitat for a variety of species of fish and wildlife. Most data collection by scientists and managers in the area has not been focused on this particular problem. Furthermore, collection of needed data may not be possible before changes in protocol are demanded. Therefore, the purpose of this document is two-fold: 1) to suggest management alternatives, given existing information, and 2) to help identify research needs that have a high probability of leading to improved simultaneous management of mosquitos, waterfowl, other wildlife, freshwater fish, and estuarine fish and shellfish on the marshland of the Merritt Island National Wildlife Refuge.

The Virtual International Stroke Trials Archive

BACKGROUND AND PURPOSE: Stroke has global importance and it causes an increasing amount of human suffering and economic burden, but its management is far from optimal. The unsuccessful outcome of several research programs highlights the need for reliable data on which to plan future clinical trials. The Virtual International Stroke Trials Archive aims to aid the planning of clinical trials by collating and providing access to a rich resource of patient data to perform exploratory analyses. METHODS: Data were contributed by the principal investigators of numerous trials from the past 16 years. These data have been centrally collated and are available for anonymized analysis and hypothesis testing. RESULTS: Currently, the Virtual International Stroke Trials Archive contains 21 trials. There are data on \u3e15,000 patients with both ischemic and hemorrhagic stroke. Ages range between 18 and 103 years, with a mean age of 69+/-12 years. Outcome measures include the Barthel Index, Scandinavian Stroke Scale, National Institutes of Health Stroke Scale, Orgogozo Scale, and modified Rankin Scale. Medical history and onset-to-treatment time are readily available, and computed tomography lesion data are available for selected trials. CONCLUSIONS: This resource has the potential to influence clinical trial design and implementation through data analyses that inform planning

Winter Field Report, December 2015 to February 2016

As has been the trend in recent years, many species are lingering later in fall and even arriving earlier in spring. Along with lingering birds, mid-winter and overwintering records have increased. This winter was phenomenal in this respect, especially in that records were across the board in terms of species, suggesting that water conditions have moderated (more open water) and temperatures in general have also (passerines). Unprecedented records included first wintering White-winged Scoter and first Jan or Feb record of Orange-crowned Warbler. Second or third such records were set by Blue-winged Teal, Surf Scoter, Ruddy Duck, Eared Grebe, Greater Yellowlegs, Rock Wren, and Yellow-rumped (Audubon\u27s) Warbler. Late-lingering species were many, highlighted by record late Red-throated Loon, Pied-billed Grebe, and Least Sandpiper. Other noteworthy laggards were Red-necked Grebe, Double-crested Cormorant, Whooping Crane, Ruby-crowned Kinglet, Hermit Thrush, Rose-breasted Grosbeak, Savannah Sparrow, Lincoln\u27s Sparrow, and Dickcissel, while Eastern Bluebirds set a new CBC high and Yellow-rumped Warblers were present through winter in almost unprecedented numbers (see last winter). Early spring arrivals are usually determined by factors other than local Nebraska environmental conditions, and so are perhaps less variable; nevertheless there were early-arriving Turkey Vulture, American Woodcock, and Franklin\u27s Gull. Perhaps the presence of these numerous winter phenomena allowed other species to winter farther north; there were no Herring Gulls reported 6-27 Jan, only 3 Red Crossbill reports were received, at least one of those of Pacific Coast Type 3 birds, and very few Townsend\u27s Solitaires were counted. Perhaps the only species that was unexpectedly low in numbers given these occurrences was Red-headed Woodpecker, virtually absent from the state, even at its winter stronghold, Indian Cave State Park. Additional significant numbers were a report of 10,000 American Robins, large numbers of Pine Siskins and American Goldfinches, and good numbers again of Yellow-bellied Sapsuckers. Interesting observations included an apparent shift eastward of wintering Brown Creepers, the still-parlous state of Black-billed Magpie in the state, now only in fair numbers in Keith and Scotts Bluff Cos. Eurasian Collared-Doves are abundant in the west, but in the east numbers are far lower, albeit increasing slowly. The third record of Barred Owl in Lincoln Co was of one in a large parking lot in North Platte; it was surmised that all three may have been hit by semis on 1-80 and transported there. As well as all of the winter excitement, there were several rarities detected, including one first state record. Unfortunately, it was Mute Swan, finally added to the state list based on numerous reports that have been difficult to pass off as escapees or released birds. In addition, Nebraska\u27s 7th Black-throated Sparrow appeared at the feeders of the Records Committee Chairman (I think it will be accepted), and there were rare sightings of Barrow\u27s Goldeneye in the east, near adult Kumlien\u27s Gull, Gyrfalcon, Common Raven (they like Applebee\u27s and Burger King), Varied Thrush, and Pine Grosbeak

A Novel Reporter Mouse Uncovers Endogenous Brn3b Expression.

Brn3b (Pou4f2) is a class-4 POU domain transcription factor known to play central roles in the development of different neuronal populations of the Central Nervous System, including retinal ganglion cells (RGCs), the neurons that connect the retina with the visual centers of the brain. Here, we have used CRISPR-based genetic engineering to generate a Brn3b-mCherry reporter mouse without altering the endogenous expression of Brn3b. In our mouse line, mCherry faithfully recapitulates normal Brn3b expression in the retina, the optic tracts, the midbrain tectum, and the trigeminal ganglia. The high sensitivity of mCherry also revealed novel expression of Brn3b in the neuroectodermal cells of the optic stalk during early stages of eye development. Importantly, the fluorescent intensity of Brn3b-mCherry in our reporter mice allows for noninvasive live imaging of RGCs using Scanning Laser Ophthalmoscopy (SLO), providing a novel tool for longitudinal monitoring of RGCs

Radiotelemetry Of Heart Rates From Free-Ranging Gulls

A lightweight radiotelemetry system with a range of 80 km was used to monitor heart rate from free-ranging Herring Gulls on flights of up to 20 km. Heart rate varied from 130 beats/min in a resting bird to 625 beats/min for sustained flight. Soaring birds showed rates similar to those of birds sitting quietly on the ground. Simultaneous records of telemetered heart rate and intraspecific conflict on the nesting island revealed that cardiac acceleration preceded overt visual communication. Intensely aggressive behavior was accompanied by heart rates approaching those of sustained flight. Heart rate as a measure of metabolic cost indicates that the gull\u27s behavioral adaptations for long-distance flight, food location and intraspecific communication result in major energy savings

Fall Field Report, August–November 2015

To start, a housekeeping item: in the species accounts that follow, whenever I use the term migrant I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall. Much of the data used in this report relating to western and Pine Ridge passerines comes from the outstanding banding efforts by Bird Conservancy of the Rockies (formerly Rocky Mountains Bird Observatory) at Chadron State Park (CSP) and Wildcat Hills Nature Center (WHNC) in Scotts Bluff Co. This year’s operators were Josh Lefever and Holly Garrod. Related to the Chadron State Park station, Andrew Pierson made this interesting observation: “I was closely involved with the CSP banding station for all of the years prior to the fires (and the first year after when it was temporarily moved down to the pond area) and it was never a very successful operation. It was always way behind the Wildcat Hills site in terms of numbers and diversity. Now, it seems there are single days when they catch a former season’s worth of birds. Is this directly attributable to the fires and subsequent regeneration of new habitat type and/or quality?” This fall and the previous two falls have been noteworthy for the large number of final sighting dates for many species that are pushing against those species’ latest expected dates. This phenomenon is across the board, both in waterbirds like Blue-winged Teal, Whooping Crane, Willet, and Common Tern, as well as passerines, such as Yellow-bellied Flycatcher (see species account for further discussion), Plumbeous Vireo, Summer Tanager, at least 5 species of sparrows, Rose-breasted Grosbeak, and Lazuli and Indigo Buntings. Conversely, a few winter visitors showed up early, such as “Oregon” and “Pink-sided” Juncos. Surprisingly large numbers of Yellow-bellied Sapsuckers and Philadelphia Vireos appeared, as in previous fall seasons, but unexpected were influxes of Palm Warblers, usually rare in fall, and Black-throated Green Warblers. Each season has its share of noteworthy happenings; this fall , check out the accounts for Osprey, which bred successfully for the first time in Nebraska, Black Rail, a mystery to hopefully be solved next June, a northeasterly nesting of Barn Owl, double-brooded American Kestrel, a tally of 266 Ruby-throated Hummingbirds passing through a Lincoln yard, and two very tardy Baltimore Orioles in Omaha. Rarities this fall were few, but headed by 4th state records of both Black-headed Gull and Black-chinned Hummingbird, the latter, oddly, in far eastern Nebraska. Reports of Cave Swallow and the western subspecies of Nashville Warbler caused struggles with identification criteria, and the presence in the state of the western form of Orange-crowned Warbler was confirmed by the Pine Ridge banding stations mentioned earlier. An update to my note in last year’s Fall Seasonal Report: at that time I mentioned that 18% of the reports I used came from eBird-only contributors. A recheck for this report shows that figure now to be 52%, obviously a significant increase in only one year. I do believe that at some point eBird will largely supersede state and local online groups like NEBirds as the repository and source for Nebraska records as long as the trend of increasing use of eBird continues. However, I believe there still is a need for analysis and comment on the data available, which is probably best done through a Seasonal Report such as this. Finally, some of you may be wondering what my guideline is for including any given species in these accounts, as some do appear some seasons but not in others. I include ALL species that are regular in occurrence for the season at hand; no Northern Shrikes in the Summer Report, for example. I include these regular species whether reported (eBird, NEBIRDS, or personally) or not, as the absence of a regular species is noteworthy. I also include any casual or accidental species that are reported. I believe it is not noteworthy if an unexpected species does not show, so not all casual/accidental species are included in any given season. Thus a casual species such as Gyrfalcon may be reported in one Winter Report but not the next
