In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250

It's not only about avocados and auto parts. Imports from Mexico can be found in almost every part of the US economy.In the first three months of the year, Mexico has moved past Canada and China to become the United States' largest trading partner, in terms of the value of goods moving back and forth over the border, with about billion a month in imports and exports so far this year.The tariffs President Donald Trump has threatened against Mexico would be broad, covering basically everything coming north across the border. They aren't targeted, the way tariffs are typically levied. The impact on business, consumers and the economy could be similarly widespread."This is going to be felt by every sector and it's going to be felt by consumers. Not just by businesses. Not just the auto industry. It's going to be felt more widely and deeply than previous tariffs were felt," said Neil Bradley, chief policy officer for the US Chamber of Commerce.Economists, stunned by the Trump administration's recent action against Mexico, were not prepared to make predictions about how much prices will increase for Americans, because they never considered such an action would take place. Blindsided businesses haven't had time to determine how to replace existing supply chains with other sources, adding stress to American companies.But some industries could be particularly hard-hit by tariffs on Mexican goods.AutosThe United States imported billion of auto parts from Mexico last year and an additional billion in completed cars. Deutsche Bank estimates that if the tariffs reach 25%, it will add an average of ,300 to the price of US cars.Demand for American-made cars could plunge 18% if the tariffs are enacted, according to that estimate. That would be the biggest drop in car sales since the auto industry teetered on ruin ten years ago during the Great Recession.ElectronicsA fifth of computer and electronic equipment imports come from Mexico, according to Goldman Sachs. That's about billion a year in electronics. Mexican televisions, monitor displays and equipment came to more than billion, or more than 35% of those imports.The United States is also set to raise tariffs on imports from China, which is another huge source of electronics. Businesses in that sector probably won't be able to escape increased costs.OilAmerica's oil industry is booming, but Mexico has become an more important source of oil for the United States, because of the cutback in production by Saudi Arabia and other OPEC nations, as well as the virtual halt of oil coming in from Venezuela.Mexico sent about billion worth of oil a month north across the border so far this year. That accounted for about 10% of all US oil imports so far this year -- nearly as much as Saudi Arabia exported to the United States. Gas prices have been stubbornly high this year because of the OPEC and Venezuelan cutbacks, and tariffs on such a significant source of oil could boost prices even further.Wires, cables and conductorsThe United States imports billion worth of Mexican wires, cables and conductors: about 50% of America's imports in the market. Although it's not the type of product that many consumers think about, American manufacturers use the components to make all types of goods.The the low-cost supply from Mexico makes the American goods they go into competitive.Food productsEating healthy is going to get more expensive with a 25% tariff on the billion worth of vegetables imported from Mexico. About 35% of all vegetable imports to the United States come from Mexico.Add in beverages, meats and cereal and Mexican food imports top billion, or about 26% of all imported food to the Untied States, according to Goldman Sachs' figures.A 25% tariff on avocados would raises costs in the United States by 5 million each year, said Johan Gott, principal at consulting firm AT Kearney. Tomatoes would cost 0 million more. Cucumbers prices would rise by 6 million, and asparagus would cost Americans 7 million each year.If the tariff remains at 25%, the cost to the beer industry will be 4 million per year, according to the Beer Institute, a trade association for the brewing industry.Air conditioners, refrigerators, furnaces and ovensMexico exported .4 billion worth of appliances to the United States last year, which amounted to 44% of American imports in that sector, according to Goldman Sachs.Dishwashers, laundry machines and other household appliances added another .1 billion worth of imports from Mexico.A potentially bigger threatThe tariffs won't apply to the goods that American farmers and manufacturers send to Mexico. But Mexico could quickly levy their own tariffs on US goods."What we've seen in the last year, when one country raises tariffs, retaliation is not far behind," said John Murphy, senior vice president, international affairs, for the US Chamber of Commerce, one of the groups opposing the tariffs."Tariffs are sand in the gears of the economy," he said. "They reduce our competitiveness." 5076

Jenny Bennett found her toddler floating in her family's pool, face-down, fully clothed. The 18-month-old had crawled through their home's pet door. An ER nurse, Bennett started CPR and rescue breathing on little Jackson while her husband called 911.Jackson was declared brain-dead after four days on life support."People automatically assume it happens to bad or neglectful parents," Bennett said.She spent two years going over and over the mistakes she made and finally decided to go public as an advocate for swim safety in her community of Tomball, Texas.Bennett thought she had taken the right precautions. She had two doors separating the house from the pool: a storm door over the back door and tight cover on the pet door. "We understood a doggy door was a risk for him to make it to the pool. We made it very clear that the dog door remains locked."But that day was unusual. She had to pick her husband up from work after his truck broke down and grabbed her three kids. With no time to let the dogs out, she opened the dog door and left the house. "I was too impatient to wait for them."When the family returned, she forgot it was open."There was a lapse in supervision. We thought he was safe upstairs with his sisters."Drowning is highly preventableThe Bennetts' story is not unusual. Nearly 1,000 children 1331

If you’re looking to make some extra cash this year, you may want to consider applying for a job with the U.S. Census Bureau.The bureau is ramping up its national recruiting efforts to hire up to 500,000 temporary, part-time census takers for the 2020 Census in communities across the country. The goal is to reach more than 2 million applicants. Officials say the positions offer competitive pay, flexible hours, paid training, and weekly paychecks. 463

JACKSON, Miss. — Days and days of heavy rain have forced authorities managing dams in Mississippi and Tennessee to release more water, worsening the flooding for people living downstream. Dramatic video posted by a Tennessee fire department showed the impact: Two houses tumbled down a bluff over the Tennessee River, while many others have been swamped to their rooftops. Entire neighborhoods have disappeared in muddy water below the Tennessee Valley Authority's Pickwick Reservoir. In Mississippi, people in and around the capital of Jackson are bracing for more flooding as the rain-swollen Pearl River is expected to crest on Monday. 651
