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

In a letter to House Democrats, Speaker Nancy Pelosi signaled Friday that she is prepared to send articles of impeachment against President Donald Trump to the Senate."I have asked Judiciary Committee Chairman Jerry Nadler to be prepared to bring to the Floor next week a resolution to appoint managers and transmit articles of impeachment to the Senate," 368

Inside a converted warehouse here, one of the largest migrant processing facilities in the country, rows of undocumented migrants filled chain-link cells as of last week.The facility, designed to hold 1,500, was crammed with 2,200 migrants detained at the border. That's nearly double the number who were there last summer.The region's central processing facility, which was built in the wake of the unaccompanied crisis five years ago, is better equipped to care for families and children than most Border Patrol stations, but its limits are being tested.Despite the near-constant attention President Donald Trump and his administration have placed on the border, illegal immigration is on the rise, leading to serious overcrowding in detention facilities like this one."We are way over capacity," said a Border Patrol official while touring the facility in McAllen with CBP Deputy Commissioner Robert Perez.Customs and Border Protection facilities in the area are overflowing with migrants who can't be processed and transferred fast enough to make room for all the new people arrested for crossing the border illegally or seeking asylum at the ports.This backlog has led CBP to begin releasing some migrants with notices to appear in court. According to a CBP official, 50 people were released on March 19, with another 200 expected to be released on March 20. The releases are a "temporary measure" being implemented "to mitigate risks to both officer safety and vulnerable populations," said the official.Immigration and Customs Enforcement has also released families along the southern border due to capacity issues and the inability to hold families longer than 20 days.Both the ICE and new CBP policies are, in effect, "catch and release" policies that the Trump administration has criticized.Separately, DHS has begun returning some asylum seekers who arrive in California to Mexico for the duration of their immigration proceedings and has indicated it plans to expand the practice across the southern border. This policy is being challenged in court.A system overwhelmed againWhile illegal border crossings are on the rise, they have not reached the record highs from the early to mid-2000s, when apprehensions often hit more than 100,000 a month along the southern border.In February, the most recent month available, 66,450 people were apprehended on the southern border.But it's the changing demographics that US officials and agencies are struggling with. Fifteen years ago, the typical migrant apprehended at the southern border was a single male from Mexico who was then quickly returned to Mexico. Today, families and children make up the majority of apprehensions. They are predominantly from the Northern Triangle countries of Guatemala, Honduras and El Salvador.Today's situation is reminiscent of the wave of unaccompanied minors apprehended at the border in the summer of 2014. Back then, Border Patrol apprehended 10,620 unaccompanied minors in one month. This February, 6,825 unaccompanied children were apprehended, along with a record 36,174 family members.In the first five months of this fiscal year, there were 163,087 apprehensions of unaccompanied minors and families -- already more than in all of 2018, which was 157,248 for the entire year."It overwhelms the resources that I have," said Rio Grande Valley Chief Patrol Agent Rodolfo Karisch about the increase in families and children. "Out of every shift, I'm having to take 20% of my workforce and dedicate them to processing, dedicate them to hospital watch and transportation, so it is very taxing on our resources."Karisch said that as the summer months approach and temperatures rise, "rescue season" begins."I don't get extra personnel, given to me for the humanitarian mission, nor do I get extra personnel for the actual rescue operations, so all of those things are very taxing," said Karisch.The problem is particularly acute in the Rio Grande Valley in Texas, already the busiest region for illegal border crossings in the country. Thirty-eight percent of all border apprehensions and 52% of marijuana seizures occur in this part of southern Texas, according to Karisch.The converted warehouseThe building in McAllen, a nondescript, beige facade, opens into warehouse space with large fenced-in cells used to divide migrants into different demographic groups- single adults, families, and unaccompanied children.Inside them, people lay next to each other under crinkling mylar blankets, others stand along the wire fence. The cement floor is lined with green gym mats. Two children pushed empty trash cans around, seemingly with nothing else to play with.One area held what appeared to be hundreds of children and parents, eating apples, potato chips and other snacks, and drinking from bottles of water and milk cartons.What to call these holding pens has become a contentious point of debate. While the CBP and Department of Homeland Security officials refer to them as "pods," Democratic lawmakers who criticize the Trump administration's have described them as cages. In a recent testimony before the House Homeland Security Committee, DHS Secretary Kirstjen Nielsen said her department does not use cages to house migrant children when questioned by House Homeland Security Chairman Rep. Bennie Thompson, D-Mississippi.CBP Deputy Commissioner Robert Perez says that calling them cages is a "mischaracterization of what the processing center actually is. It is a center that is there and meant for and indented to, in the most safest means possible, to take these most vulnerable populations and afford us as the front line law enforcement agency the best ability to deliver the care and processing that we are responsible to do for those very vulnerable populations.""That really struck me, the care with which our agents are taking care of this population," said Perez. "The other thing that struck me was, how saturated we are. A facility, very well-equipped, very well-resourced, nevertheless overwhelmed by the virtue of just the sheer numbers of people that we are seeing."The group, including CBP officials and two journalists, entered one of the cells, labeled "red pod C." There, an agent stood guard on top of a painted red structure, reminiscent of a lifeguard tower, and stood above to watch what was happening inside."We do have fights from time to time, which is why we have to have an open facility," said another Border Patrol official as we walked through the center.There are also laundry facilities and showers in the building -- not available at all of the stations in the region or across the border. CBP also purchases new clothing, which are given to migrants while their personal garments are being washed.A group of border agents assigned to handle unaccompanied minor cases worked feverishly at a long row of desks. Another row of desks, although empty when CNN was there, are meant for consular officers that can help US officials determine if the documents brought by migrants, primarily from Central American countries, are legitimate."This needs to be a whole of government, regional problem, not just CBP and DHS," said one of the officials on the tour.Length of stayThe goal is to move people out of the processing center and other Border Patrol facilities within 72 hours, but that doesn't always happen."Some of these folks have been sitting here for days, not hours," said a senior Border Patrol official on the walkthrough.The average length of stay in the facility is currently 60 hours, but that drops to 32 hours for families, according to the official.The McAllen center was designed to temporarily house migrants so they can be processed and transferred to other agencies. Families and adults are generally released to Immigration and Customs Enforcement custody, while unaccompanied children are transferred to the Department of Health and Human Services.Although agents want to move people out the center as quickly as possible, the short turnaround presents another problem -- how to verify familial relationships.For example, even if a document is determined to be legitimate, agents have to determine whether it's fraudulent. Additionally, only children older than 14 are fingerprinted, leaving a gap in the biometric data that can be gathered.After a couple hours touring the facility and border in McAllen, Perez noted that it's not just the Border Patrol facilities, but the entire US immigration system that is backlogged. "The system is overwhelmed," he said.The border and the portsLater that day, about 10 miles away from the McAllen processing center, agents lined up a group of about a migrants just apprehended near the Anzalduas International Bridge along the border with Mexico. Agents asked all the migrants for their information and documents. Among those apprehended were Xiomara and her adolescent son. She said they fled extortion and death threats in her home country of Guatemala."They give you days to give them the money, and if not, they'll kill you," she said in Spanish.At the time Xiomara and her son were encountered, Border Patrol had apprehended 600 people for the day. By the end of the day, 1,420 people had been taken into custody -- making it the second-busiest day in the sector since 2014.Several miles to the east, the Hidalgo Port of Entry was also overwhelmed with asylum-seekers. On Friday, there were 77 migrants in the 35-person capacity facility."How do we handle this many people?" asked the CBP official giving a tour of the port.The port has converted its offices into holding facilities for families and uses its original holding cells for bathrooms. Inside the port, there was a closet filled with Pedialyte, Nestle formula, children's clothing and other goods.At night, officers put down mats and provide blankets so migrants have somewhere to sleep.Migrants are sent to various processing facilities in the area depending on which facility has availability. However, agents aim to send all unaccompanied minors to the central processing center in McAllen."Especially right now" the region's facilities are overcapacity, said Chief Karisch, adding the Border Patrol stations and the processing center in McAllen are "exactly what they are --processing, short-term holding facilities," he said. 10299

In a series of emotional interviews on Tuesday, George Floyd's daughter and her mother remembered Floyd as a "good man" and "super fun dad."Roxy Washington, the mother of Floyd's 6-year-old daughter Gianna, told reporters that she hopes the officers who arrested him face consequences for Floyd's death."This is what those officers took from me," Washington said through tears. "At the end of the day, they get to go home and be with their families. Gianna does not have a father. He will never see her grow up, graduate. He will never walk her down the aisle. If she has a problem and needs her dad, she does not have that anymore."Washington added that even though she and Floyd and their "ups and downs," she still considered him a good person."I'm here for my baby, and I miss George because I want justice for him. I want justice for him because he was good. No matter what anybody says, he was a good man. And this is the proof that he was good," Washington said.In a later interview, Washington described talking to Gianna and telling her how her father had died. She said she wasn't planning on revealing everything about her father's death, but Gianna overheard TV coverage."She said, 'Mom, something is going on with my family.' I said, 'why do you say that?' And she said, 'because I hear them saying my daddy's name on TV," Washington said. "She wanted to know how he died. And the only thing that I can tell is he couldn't breathe."Gianna described her father to reporters as a "super fun dad" who often carried her on his back.A video of Gianna taken on Tuesday, which was later shared on Twitter by Bernice King, the daughter of Martin Luther King, Jr., Gianna said that her father "changed the world." 1731
