Meesia uliginosa Hedw. (Musci, Meesiaceae) in Antarctica

first_imgMeesia uliginosa Hedw. and the family Meesiaceae are recorded for the first time in the Antarctic. The species is occasional on Joinville and James Ross Islands near the Trinity Peninsula, on Signy Island in the South Orkney Islands and on Livingston and Robert Islands in the South Shetland Islands, whereas on King George Island, in the latter archipelago, it is locally frequent. The Antarctic plants are briefly described and illustrated and the local distribution of the species on King George Island and in the maritime Antarctic is mapped. The ecological requirements of M. uliginosa in Antarctica are described in detail and the global geographical distribution of the species is reviewed. Ceratodon kinggeorgicus Kanda, a species originally described from King George Island, is considered to be conspecific with M. uliginosa.last_img read more

The effects of global climate variability in pup production of Antarctic fur seals

first_imgClimate variability has strong effects on marine ecosystems, with repercussions that range in scale from those that impact individuals to those that impact the entire food web. Climate-induced changes in the abundance of species in lower trophic levels can cascade up to apex predators by depressing vital rates. However, the characteristics and predictability of predator demographic responses remain largely unexplored. We investigated the detectability, limits, and nonlinearity of changes in Antarctic fur seal pup production at South Georgia over a 20-year period in response to environmental autocorrelation created by global climate perturbations; these were identified in time series of monthly averaged sea surface temperature (SST). Environmental autocorrelation at South Georgia was evident with frequent SST anomalies between 1990 and 1999, during a decade of warm background (time-averaged) conditions. SST anomalies were preceded by, and cross-correlated with, frequent El Niño-La Niña events between 1987 and 1998, which was also a decade of warm background conditions in the tropical Pacific Ocean. Nonlinear mixed-effects models indicated that positive anomalies at South Georgia explained extreme reductions in Antarctic fur seal pup production over 20 years of study. Simulated environmental time series suggested that the effect of anomalies on Antarctic fur seals was only detectable within a narrow range of positive SST, regardless of the distribution, variance, and autocorrelation structure in SST; this explained the observed nonlinearity in responses in pup production, which were observed only under persistent high SST levels. Such anomalies at South Georgia were likely associated with low availability of prey, largely krill, which affected Antarctic fur seal females over time scales longer than their breeding cycle. Reductions in Antarctic fur seal pup production could thus be predicted in advance by the detection of large-scale anomalies, which appeared to be driven by trends in global climate perturbation.last_img read more

Can bottom ice algae tolerate radiative and temperature changes?

first_imgSea ice algae are significant primary producers of the ice-covered marine environment, growing under typically cold, dim conditions. During ice break-up they are released to the water column, where temperatures can be several degrees higher and irradiance can increase by orders of magnitude. To determine how sea ice algae respond to such rapid changes, we carried out incubations to examine their tolerance to environmentally realistic levels of change in temperature and PAR, as expressed by photosynthetic response and production of mycosporine-like amino acids (MAAs). The algae were also exposed to a broader range of temperatures, to evaluate their potential to function in warmer seas in the event, for instance, of anthropogenic transfer to locations further north. When subjected to PAR (0–100 μmol m− 2 s− 1) at ecologically relevant temperatures (− 1 °C, 2 °C, 5 °C), the algae showed tolerance, indicated by a lack of decline in the quantum efficiency of photosystem II (PSII). The data show that bottom ice algae can tolerate increasing temperature and PAR comparable to the changes experienced during and after sea ice melt. MAA production increased at higher PAR and temperature. At ambient PAR levels, increased temperatures resulted in lower ϕPSII. However, as PAR levels were increased, higher temperature reduced the level of stress as indicated by higher ϕPSII values. This result suggests, for the first time in sea ice algal studies, that higher temperatures can ameliorate the negative effects of increased PAR. Exposure to much higher temperatures suggested that the algae were capable of retaining some photosynthetic function at water temperatures well above those currently experienced in some of their Antarctic habitats. However, when temperature was gradually increased past 14 °C, the photosystems started to become inactivated as indicated by a decrease in quantum yield, suggesting that the algae would not be viable if transferred to lower latitude cold temperate areas.last_img read more

Reversal: Trial Court Ordered To Revisit CHINS Petition

first_imgReversal: Trial Court Ordered To Revisit CHINS PetitionOlivia Covington for www.theindianalawyer.comAn Indiana trial court imposed an “inappropriately high” burden on the Department of Child Services to prove a presumption of a child in need of services situation, the Indiana Court of Appeals held Friday in an opinion ordering the trial court to revisit the CHINS petition.In Indiana Department of Child Services v. J.D., R.B., et al, 71A03-1611-JC-2627, DCS received a report that M.B., a child, had been seen in the emergency room for multiple fractures, including several rib fractures. DCS Family Case Manager Bridget Murray spoke with R.B., the mother, and doctors at the hospital, where she learned M.B. began exhibiting symptoms of a fractured rib the after being removed from his car seat the previous day.A physician, however, told Murray it was not feasible for M.B.’s injuries to have been caused simply by removal from his car seat, but that the pattern of the rib fractures showed signs of the child being squeezed. Murray concluded it was necessary to remove M.B. from R.B.’s care, so he was placed in foster care immediately upon his release from the hospital.DCS then filed a petition alleging M.B. was a Child in Need of Services, and a fact-finding hearing was held in August 2016. Murray testified to the events leading up to M.B.’s removal, and three physicians testified his injuries were very likely non-accidental and had occurred during at least two separate incidents of trauma. R.B., J.D., the child’s father, and L.M., the mother’s boyfriend, also testified at the hearing and each denied observing any injuries or odd behaviors in M.B. before he was taken out of the car seat.DCS argued it had presented sufficient evidence to trigger presumption under Indiana Code section 31-34-12-4, or the Presumption Statute, that M.B. was a CHINS, but the St. Joseph Probate Court disagreed and ordered the child returned to R.B.’s care. After the denial of its motion to correct error, DCS appealed, arguing the trial court had committed reversible legal error “by failing to give effect to the presumption set forth in I.C. section 31-34-13-4” and by rejecting the physicians’ testimonies to the non-accidental nature of M.B.’s injuries.The Indiana Court of Appeals agreed with DCS, with Judge Robert Altice writing in a unanimous Friday opinion the trial court’s statements, such as the sentiment that it was “absurd” for the doctors to determine the injuries were non-accidental, were “problematic.”For example, Altice wrote the question of whether the injuries were non-accidental was a question of fact, not law, as the trial court presumed, an error that “effectively required the court to disregard the physicians’ testimony that Child’s injuries were non-accidental.” Further, the court’s conclusion the physicians were unqualified to opine as to the nature of the injuries was the wrong approach, Altice said.Additionally, the trial court “imposed an inappropriately high evidentiary burden on DCS to trigger the Presumption Statute,” the appellate panel said. That statute merely requires “competent evidence of probative value,” which DCS provided in the form of the evidence and testimony at the fact-finding hearing, the court said.Thus, because the evidence was sufficient to trigger the Presumption Statute, the appellate panel reversed the trial court’s denial of the CHINS petition and remanded the case with instructions to conduct further proceedings.FacebookTwitterCopy LinkEmailSharelast_img read more

Water lilies

first_imgBy Sharon OmahenUniversity of GeorgiaA water garden wouldn’t be complete without the flowers and pads provided by water lilies. A University of Georgia expert says Georgia’s climate allows most home gardeners to grow both hardy and tropical lilies.”Hardy lilies are typically those with smooth-edged pads and flowers that sit close to the top of the water,” said Tony Johnson, a horticulturist at the UGA Research and Education Garden in Griffin, Ga. “Tropical lilies usually have leaves with serrated edges and blooms that grow atop tall stems.”Decades of experienceJohnson should know the difference. An award-winning landscape designer, he has installed water gardens for the past 25 years. As the lead horticulturist at the UGA garden in Griffin, he maintains the garden’s two water elements. And he shares his knowledge through water gardening classes.”If you want reliable, perennial plants, install hardy lilies,” he said. “Ponds and lakes in south Georgia are just covered with these lilies.”Although they “typically” won’t overwinter in Georgia, Johnson recommends adding a few tropical lilies for effect. “If you love water lily flowers, tropicals produce more blooms per season than hardy lilies,” he said. “They’re really worth the extra money for that reason alone.”If you have access to a greenhouse, you can place the tropical lilies there during the winter and try to save them for the next year. “Most people don’t have access to a greenhouse, though,” he said. “And tropicals aren’t that expensive, so it’s just easier to buy a few new ones every year.”Tropicals bloom at nightJohnson recommends tropical lilies if you visit your water garden at night. “Tropical lilies are the only ones that are night-blooming,” Johnson said. “If you entertain at night by your water pond, these lilies make a really nice addition.”Whichever lily you chose, keep the plant’s leaves as dry as possible.”This sounds strange when you’re talking about water garden plants,” Johnson said. “But lilies breathe through the leaves. So don’t place them in an area where a fountain or waterfall will constantly be putting water on top of the leaves.”Like other garden plants, water lilies need to be fertilized. Do this once a month during the growing season, Johnson said.”In (middle and south Georgia), both tropical and hardy lilies will do well,” he said. “We’ve had mild winters the last few years that have allowed the tropical lilies to come back.”To learn more about installing and maintaining a water garden, visit UGA on the Web at read more
