iStock/Thinkstock(LEXINGTON PARK, Md.) — The 14-year-old boy who was allegedly shot by a classmate at his Maryland high school has been released from the hospital, MedStar St. Mary’s Hospital said Wednesday.The 14-year-old, who suffered a gunshot wound to the thigh, was one of two teenagers shot and injured in a Great Mills High School hallway just before classes began on Tuesday.The other victim, a 16-year-old girl, may have had a prior relationship with the shooting suspect, 17-year-old Austin Rollins, according to authorities. The extent of any relationship between them was unclear and the motive remains under investigation.Rollins died after exchanging gunfire with school resource officer Deputy Blaine Gaskill, authorities said. It was not immediately clear if the officer or the suspect fired the fatal shot.While the 14-year-old boy has been released, the injured 16-year-old girl remains in critical condition, according to UM Prince George’s Hospital Center.St. Mary’s County Sheriff Tim Cameron called the shooting “our worst nightmare.”“This is what we prepare for,” he said. “And this is what we pray we never have to do.”Principal Jake Heibel said in a statement, “Words cannot express the sadness and grief that our school community is feeling right now.”“I know that we are shaken and scared after today’s events and will struggle for sometime trying to make sense of it all,” Heibel said. “I do not know exactly how but we will find a way to overcome this tragedy. Now more than ever we need to stand together as a school community to love, cherish, and support one another. We have and we will continue to stay strong, stay together, and find a way to get through this.”The high school is closed for the rest of the week and will reopen after spring break on April 2. Counseling is available, the principal said.This shooting came four days before Saturday’s March for Our Lives in nearby Washington, D.C. Thousands of students are expected to descend on the nation’s capital to rally for gun control and safer schools in the wake of the deadly Feb. 14 school shooting in Parkland, Florida.Less than one week before Great Mills High School faced its own shooting, its students were among the thousands participating in the National School Walkout, according to local news outlet TheBayNet.com.The walkout, which marked a month since the Parkland massacre, was organized as a call on Congress to tighten gun laws.Copyright © 2018, ABC Radio.

Marine vertebrates show a diversity of migration strategies, including sex differences. This may lead to differential demography, but the consequences of such between-sex variation are little understood. Here, we studied the migration of known-sex northern gannets Morus bassanus—a partial migrant with females ~8% heavier than males. We used geolocators to determine wintering areas of 49 breeding adults (19 females and 30 males during 2010 to 2014) from 2 colonies in the northeast Atlantic (Bass Rock and Grassholm, UK). We also tested for sex-specific survival probabilities using capture-mark-recapture methods (n = 72 individuals Bass Rock, n = 229 individuals Grassholm; 2010-2018) and applied sex-specific population projection matrices (PPMs) to quantify population-level effects. Tracked gannets wintered in a range of large marine ecosystems (LMEs): Canary Current LME (CCLME; 69%), Celtic-Biscay Shelf LME (16%), Iberian Coastal LME (8%), North Sea LME (4%) or Mediterranean LME (2%). Migratory destination differed between the sexes: 90% of females vs. 57% of males wintered in the CCLME. Survival was similar between the sexes at Bass Rock (mean ± 95% CI = 0.951 ± 0.053 and 0.956 ± 0.047 for females and males, respectively). At Grassholm, there was evidence of slight sex differences in breeder survival: females had lower annual survival (0.882 ± 0.040) than males (0.946 ± 0.026). At Bass Rock, PPMs with no sex effect best fitted the observed population increase (1994-2014). Sex-specific PPMs fitted the population estimates for Grassholm (1995-2015). Our results reveal that female gannets are more likely to travel further than males to winter in the CCLME. This difference is unlikely due to morphological differences, unlike in other bird species. However, the reason for slightly higher over-winter female mortality at Grassholm is unclear.
