Marine microbial populations: Potential sensors of the global change in the ocean      (via sciencedaily.com)     Original source 

Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.

East coast mussel shells are becoming more porous in warming waters      (via sciencedaily.com)     Original source 

Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.

How soil microbes survive in harsh desert environments      (via sciencedaily.com)     Original source 

Prolonged droughts followed by sudden bursts of rainfall -- how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by microbiologists. The study reveals that desert soil bacteria are highly adapted to survive the rapid environmental changes experienced with each rainfall event.

Copper beads in pig feed reshape swine gut microbiome      (via sciencedaily.com)     Original source 

Copper is a natural antimicrobial material that, when added to pig feed, may promote the growth and health of the animals. Since pigs can tolerate high levels of the metal, researchers recently investigated whether copper might be used to promote their gut health and reduce the shedding of microbes to the environment.

Huge database gives insight into salmon patterns at sea      (via sciencedaily.com)     Original source 

A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The project integrates numerous international salmon studies from the North Pacific dating back to the 1950s.

Older males out-compete young males outside breeding pairs, bird study shows      (via sciencedaily.com)     Original source 

Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, researchers report.

New tagging method provides bioadhesive interface for marine sensors on diverse, soft, and fragile species      (via sciencedaily.com)     Original source 

Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.

Florida Wildlife Corridor eases worst impacts of climate change      (via sciencedaily.com)     Original source 

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.

Hidden threat: Global underground infrastructure vulnerable to sea-level rise      (via sciencedaily.com)     Original source 

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.

Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom      (via sciencedaily.com)     Original source 

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste' errors allowed animals to keep one copy of their genome or genes for fundamental functions, while the second copy could be used as raw material for evolutionary innovation. Events like these, at varying degrees of scale, occurred constantly throughout the bilaterian evolutionary tree and enabled traits and behaviours as diverse as insect flight, octopus camouflage and human cognition.

Tropical forests can't recover naturally without fruit-eating birds      (via sciencedaily.com)     Original source 

Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests.
