Midweek success keeping USC afloat

first_imgThe middle of the week has been kind to the Trojans.And with wins coming at a premium in the grueling Pac-10 conference, they need that to remain the case tonight.Important · Sophomore infielder Ricky Oropesa’s team leading nine home runs and 29 RBI have helped keep USC’s record near .500. Oropesa and USC take on Cal State Bakersfield tonight at Dedeaux Field. – Brandon Hui | Daily Trojan USC takes on Cal State Bakersfield at 6:30 p.m. at Dedeaux Field, the first ever meeting between the two teams.The Trojans (14-14) have excelled in midweek games in 2010, winning five of six. Their only loss came on March 10, a 5-4 defeat against Connecticut. In those five victories, the Trojans have outscored their opponents 33-19.Despite the midweek success, USC has been inconsistent. The Trojans are now 2-4 in Pac-10 play after dropping two of three to Oregon State.They have won just one game in each of their first two conference series and have lost three straight series overall since taking three of four from Hawai’i in the middle of March.The Roadrunners (12-14) have also struggled with inconsistency this year. They won four games in a row to open the season, but followed that streak with eight losses in 10 games.Bakersfield is coming off a series sweep by Fresno State in which it was outscored 36-22.The Trojans have shown flashes of brilliance in this streaky season. They had chances to win both games they dropped to Oregon State, as was the case two weekends ago at Stanford.Sophomore infielder Ricky Oropesa remains on a tear, leading USC with a .333 average, nine home runs and 29 RBI. Sophomore infielder Matt Foat is right behind him with an identical batting average and 27 RBI.But USC has had difficulties finding hits in some key situations. Junior infielder Joe De Pinto struck out to end Saturday’s game in the bottom of the ninth, leaving the tying run on third base and the winning run on second. The Beavers held on for a 4-3 win.And in Thursday’s loss, the Trojans put the winning run on second base with one out in the bottom of the ninth, but failed to bring him in. Oregon State broke through with three runs in the top of the 10th and won 4-1.The Trojans have also had trouble at home. They are just 4-8 at Dedeaux Field and 10-6 away from it.But they have a chance to reverse that mark by the end of the week as USC wraps up a seven-game homestand against California. After tonight’s game, the Trojans will host Cal in a three-game series starting Friday.USC currently sits at 10th in the conference, tied with Arizona and Oregon at 2-4 in Pac-10 play.last_img read more

Without lots of genetic material to reshuffle, future generations are less able to adapt to changing environmental conditions. Now, a new genetic analysis of narwhals is turning that notion on its head: Despite low genetic diversity, these “unicorns” of the ocean seem to be doing just fine.Narwhals, medium-size whales that live in the Arctic, are known for some genetic quirks. After multiple studies uncovered low genetic diversity in several narwhal genes, a team of researchers decided to analyze the whale’s entire genome. Using DNA from the frozen liver tissue of a narwhal found near Greenland, they calculated the genetic variation of the species and estimated the population size of narwhals into the deep past.Their results reveal a profound lack of diversity across the narwhal’s genome, they report today in iScience. Compared with 14 other mammal species, narwhals were far less genetically diverse. For example, bowhead whales have twice as much variation, while pandas’ genomes are more than three times as diverse. What’s more, the team found no evidence of an inbreeding or die-off “bottleneck.” Instead, narwhal populations appear to have declined slowly starting 2 million years ago and have maintained a low genetic diversity for the past million years. Such slowly shrinking diversity has been seen in mountain gorillas and Channel Island foxes, but this time, the common culprits of inbreeding and isolation don’t appear to be to blame.

Required fields are indicated by an asterisk (*) The narwhal’s abundance—there are more than 170,000 living in the wild—may come from a population explosion driven by favorable environmental conditions 115,000 years ago. Since then, genetic diversity may simply have not had enough to time to catch up. But the researchers note that the narwhal isn’t totally out of the woods; with a range restricted to the rapidly warming Arctic, it’s unclear whether the narwhal’s uniform genome will be able to cope with ongoing climate change.last_img read more
