Remember When, Chattanooga? Schroeder's Garden Center was a thriving store near the McCallie Avenue viaduct in the 1950s - Chattanooga Times Free Press |
| Posted: 16 Apr 2021 06:02 PM PDT  These men, dressed in 1950s work clothes, represent the staff of Schroeder's Garden Center, which was located near the McCallie Avenue viaduct in Chattanooga. One of the vehicles in this 1959 photo is painted with the business's alliterative motto: "Good landscaping doesn't just happen, it's planned and planted properly." In mid-century Chattanooga, the business, owned by entrepreneur William F. Schroeder, had two locations: the Duncan Avenue store near the viaduct (seen here) and a downtown store at 510 Market St. The Duncan Avenue address is now the site of the Montessori School. The photo is taken from a collection of Chattanooga News-Free Press photographs kept at ChattanoogaHistory.com, a website devoted to legacy photos of the city and curated by history buff Sam Hall. John Goforth, a staff photographer for the newspaper in the 1950s, took the picture.

William F. Schroeder's 1979 obituary in the News-Free Press notes that he was a 1933 graduate of Tulane University, playing on the school's 1931 football team that competed in the Rose Bowl. Schroeder spent 40 years as a Chattanooga business owner before his death, according to newspaper records. He was survived by his wife, Mary Wilbert Schroeder and three children. Schroeder and his wife were residents of Riverview at the time of his death. He was 67 years old. In 1959, the year this photo was taken, ads in the newspaper's classifieds section noted that the Market Street location of Schroeder's operation stocked tropical fish, aquariums and supplies, in addition to gardening items. Around Easter that year a big display advertisement in the newspaper for Schroeder's offered chicks for 25 cents each and rabbits for $2. Double carnation corsages were $1.49 and triple corsages were $1.98. Easter lilies sold for $3.49 and up. Follow the "Remember When, Chattanooga?" public group on Facebook.

| Are fish migrations revealing a massive extinction event is on the way? - Inverse Posted: 17 Apr 2021 01:00 PM PDT The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays, and whale sharks. The number of marine species naturally tapers off as you head towards the poles. Ecologists have assumed this global pattern has remained stable over recent centuries — until now. Our recent study found the ocean around the equator has already become too hot for many species to survive, and that global warming is responsible. In other words, the global pattern is rapidly changing. And as species flee to cooler water towards the poles, it's likely to have profound implications for marine ecosystems and human livelihoods. When the same thing happened 252 million years ago, 90% of all marine species died. The bell curve is warping dangerouslyThis global pattern — where the number of species starts lower at the poles and peaks at the equator — results in a bell-shaped gradient of species richness. We looked at distribution records for nearly 50,000 marine species collected since 1955 and found a growing dip over time in this bell shape.  So, as our oceans warm, species have tracked their preferred temperatures by moving towards the poles. Although the warming at the equator of 0.6℃ over the past 50 years is relatively modest compared with warming at higher latitudes, tropical species have to move further to remain in their thermal niche compared with species elsewhere. As ocean warming has accelerated over recent decades due to climate change, the dip around at the equator has deepened. We predicted such a change five years ago using a modeling approach, and now we have observational evidence. For each of the 10 major groups of species, we studied (including pelagic fish, reef fish and mollusks) that live in the water or on the seafloor, their richness either plateaued or declined slightly at latitudes with mean annual sea-surface temperatures above 20℃. Today, species richness is greatest in the northern hemisphere in latitudes around 30°N (off southern China and Mexico) and in the south around 20°S (off northern Australia and southern Brazil).  This has happened beforeWe shouldn't be surprised global biodiversity has responded so rapidly to global warming. This has happened before, and with dramatic consequences. 252 million years ago… At the end of the Permian geological period about 252 million years ago, global temperatures warmed by 10℃ over 30,000-60,000 years as a result of greenhouse gas emissions from volcano eruptions in Siberia. A 2020 study of the fossils from that time shows the pronounced peak in biodiversity at the equator flattened and spread. During this mammoth rearranging of global biodiversity, 90% of all marine species were killed. 125,000 years ago… A 2012 study showed that more recently, during the rapid warming around 125,000 years ago, there was a similar swift movement of reef corals away from the tropics, as documented in the fossil record. The result was a pattern similar to the one we describe, although there was no associated mass extinction. Authors of the study suggested their results might foreshadow the effects of our current global warming, ominously warning there could be mass extinctions in the near future as species move into the subtropics, where they might struggle to compete and adapt. Today… During the last ice age, which ended around 15,000 years ago, the richness of forams (a type of hard-shelled, single-celled plankton) peaked at the equator and has been dropping there ever since. This is significant as plankton is a keystone species in the food web. Our study shows that decline has accelerated in recent decades due to human-driven climate change. The profound implicationsLosing species in tropical ecosystems means ecological resilience to environmental changes is reduced, potentially compromising ecosystem persistence. In subtropical ecosystems, species richness is increasing. This means there'll be species invaders, novel predator-prey interactions, and new competitive relationships. For example, tropical fish moving into Sydney Harbour compete with temperate species for food and habitat. This could result in ecosystem collapse — as was seen at the boundary between the Permian and Triassic periods — in which species go extinct and ecosystem services (such as food supplies) are permanently altered.  The changes we describe will also have profound implications for human livelihoods. For example, many tropical island nations depend on the revenue from tuna fishing fleets through the selling of licenses in their territorial waters. Highly mobile tuna species are likely to move rapidly toward the subtropics, potentially beyond sovereign waters of island nations. Similarly, many reef species important for artisanal fishers — and highly mobile megafaunas such as whale sharks, manta rays and sea turtles that support tourism — are also likely to move toward the subtropics. The movement of commercial and artisanal fish and marine megafauna could compromise the ability of tropical nations to meet the Sustainable Development Goals concerning zero hunger and marine life. Is there anything we can do?One pathway is laid out in the Paris Climate Accords and involves aggressively reducing our emissions. Other opportunities are also emerging that could help safeguard biodiversity and hopefully minimize the worst impacts of it shifting away from the equator. Currently, 2.7% of the ocean is conserved in fully or highly protected reserves. This is well short of the 10% target by 2020 under the UN Convention on Biological Diversity.  But a group of 41 nations is pushing to set a new target of protecting 30% of the ocean by 2030. This "30 by 30" target could ban seafloor mining and remove fishing in reserves that can destroy habitats and release as much carbon dioxide as global aviation. These measures would remove pressures on biodiversity and promote ecological resilience. Designing climate-smart reserves could further protect biodiversity from future changes. For example, reserves for marine life could be placed in refugia where the climate will be stable over the foreseeable future. We now have evidence that climate change is impacting the best-known and strongest global pattern in ecology. We should not delay actions to try to mitigate this.
