Tue, 05 Sep 2023 12:50:10 EDT //www.koonmotors.com/releases/2023/09/230905125010.htm Most species are rare, but not very rare //www.koonmotors.com/releases/2023/09/230904133135.htm More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. A new study demonstrates how important biodiversity monitoring is for detecting species abundances on planet Earth and for understanding how they change. Mon, 04 Sep 2023 13:31:35 EDT //www.koonmotors.com/releases/2023/09/230904133135.htm Mutation rates in whales are much higher than previously reported //www.koonmotors.com/releases/2023/08/230831142901.htm An international team of marine scientists has studied the DNA of family groups from four different whale species to estimate their mutation rates. Using the newly determined rates, the group found that the number of humpback whales in the North Atlantic before whaling was 86 percent lower than earlier studies suggested.

This malfunctioning is usually explained by the need for microbes to perform unique and beneficial functions, but evolutionary ecologist is questioning that narrative. Tue, 29 Aug 2023 13:00:34 EDT //www.koonmotors.com/releases/2023/08/230829130034.htm Male crested macaques more likely to respond to offspring screams recruiting support //www.koonmotors.com/releases/2023/08/230829130028.htm When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010). Tue, 29 Aug 2023 13:00:28 EDT //www.koonmotors.com/releases/2023/08/230829130028.htm Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution //www.koonmotors.com/releases/2023/08/230829125929.htm Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans. Tue, 29 Aug 2023 12:59:29 EDT //www.koonmotors.com/releases/2023/08/230829125929.htm Curious and cryptic: New leaf insects discovered //www.koonmotors.com/releases/2023/08/230828162413.htm An international research team has described seven previously unknown species of leaf insects, also known as walking leaves. The insects belong to the stick and leaf insect order, which are known for their unusual appearance: they look confusingly similar to parts of plants such as twigs, bark or -- in the case of leaf insects -- leaves. This sophisticated camouflage provides excellent protection from predators as well as presenting a challenge to researchers. Genetic analysis enabled the researchers to discover 'cryptic species', which cannot be distinguished by their external appearance alone. The findings are not only important for the systematic study of leaf insects, but also for the protection of their diversity. Mon, 28 Aug 2023 16:24:13 EDT //www.koonmotors.com/releases/2023/08/230828162413.htm How a cup of water can unlock the secrets of our Universe //www.koonmotors.com/releases/2023/08/230823165413.htm A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it. Wed, 23 Aug 2023 16:54:13 EDT //www.koonmotors.com/releases/2023/08/230823165413.htm Natural selection can slow evolution, maintain similarities across generations //www.koonmotors.com/releases/2023/08/230823165407.htm New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its stamens, or pollen-producing parts, two of which are short and four are long. Roughly 55 million years ago, wild radish ancestors had stamens of equal length. The team selectively bred -- or artificially selected -- wild radish to reduce the difference in stamen length and return the plant to a more ancestral look. This shows that today's wild radish and, likely, its family members still have the requisite genetic variability to evolve, but natural selection is preserving its different stamen lengths. Wed, 23 Aug 2023 16:54:07 EDT //www.koonmotors.com/releases/2023/08/230823165407.htm Fungus gnats as pollinators not pests //www.koonmotors.com/releases/2023/08/230823122515.htm Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution. Wed, 23 Aug 2023 12:25:15 EDT //www.koonmotors.com/releases/2023/08/230823122515.htm It all depends on the genetic diversity //www.koonmotors.com/releases/2023/08/230821153158.htm New research shows that a single mutation that has immediate effects on plant fitness is maintained over the long term in natural plant populations, despite theories predict the contrary. The researchers located and identified the gene that regulates the amount of an active defense hormone. Mutants in this gene are susceptible to herbivore attack. However, they compensate for impaired defenses through robust genetic networks. When fewer herbivores attack, they even grow faster and produce more offspring. Mon, 21 Aug 2023 15:31:58 EDT //www.koonmotors.com/releases/2023/08/230821153158.htm The modern sea spider had started to diversify by the Jurassic, study finds //www.koonmotors.com/releases/2023/08/230817164019.htm An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.

Fri, 11 Aug 2023 14:38:26 EDT //www.koonmotors.com/releases/2023/08/230811143826.htm High-precision genome sequencing of buckwheat breeds hope for future harvests //www.koonmotors.com/releases/2023/08/230811115532.htm Buckwheat's high-precision chromosomal-level genome sequence has been deciphered, a key step toward unraveling the evolution of the buckwheat genome and the origins of the cultivated crop. By altering specific genes using a method independent of common genome-editing techniques, the researchers successfully developed a self-fertile buckwheat variety as well as a new type of the crop with a sticky, mochi-like texture. This breeding method may contribute to a more diverse range of orphan crops than what is possible with existing genome editing technologies.

In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered that in at least one species, the variation results from a vision gene's jump onto a sex chromosome. It's the first known finding that this kind of genetic change causes sexually dimorphic vision. Thu, 10 Aug 2023 14:10:02 EDT //www.koonmotors.com/releases/2023/08/230810141002.htm The oldest and fastest evolving moss in the world might not survive climate change //www.koonmotors.com/releases/2023/08/230809130617.htm A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

The insights could help scientists to better understand how bacteria rapidly adapt and evolve, and how they become more virulent and resistant to antibiotics. Fri, 04 Aug 2023 12:37:51 EDT //www.koonmotors.com/releases/2023/08/230804123751.htm How the hospital pathogen Acinetobacter baumannii quickly adapts to new environmental conditions //www.koonmotors.com/releases/2023/08/230804123721.htm Hospital-acquired infections are often hard to treat because the corresponding pathogens become increasingly resistant against antibiotics. The bacterium Acinetobacter baumannii is particularly feared, and there is great pressure to devise novel therapeutic approaches to combat it. Bioinformaticians have now detected an unexpectedly wide diversity of certain cell appendages in A. baumannii that are associated with pathogenicity. This could lead to treatment strategies that are specifically tailored to a particular pathogen. Fri, 04 Aug 2023 12:37:21 EDT //www.koonmotors.com/releases/2023/08/230804123721.htm DNA tilts and stretches underlie differences in mutation rates across genomes //www.koonmotors.com/releases/2023/08/230803132228.htm Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide mutation rates meaningfully and consistently, and this is likely conserved among species.

By examining one of the largest global Pliocene collections of fossils in Langebaanweg, north of Cape Town in South Africa, researchers present two new sabertooth species and the first family tree of the region's ancient sabertooths. Their results suggest that the distribution of sabertooths throughout ancient Africa might have been different than previously assumed, and the study provides important information about Africa's paleoenvironment.

This phenotypic plasticity has been shown to be expressed by a variety of factors, including predator type, predator mode, and density. Overall, the small and medium-sized Daphnia expressed the highest degree of predator-induced plasticity, which the team found was more evident in small Daphnia than would be expected from size-selective predation.

A new study reveals another strange trait shared by different hairworm species: they're missing about 30% of the genes that researchers expected them to have. What's more, the missing genes are responsible for the development of cilia, the hair-like structures present in at least some of the cells of every other animal known. 星期二,2023年7月18日16:42:56美国东部时间 //www.koonmotors.com/releases/2023/07/230718164256.htm Form and function of island and mainland plants //www.koonmotors.com/releases/2023/07/230714163216.htm Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy.

Wed, 12 Jul 2023 20:37:52 EDT //www.koonmotors.com/releases/2023/07/230712203752.htm DNA element with a murky past is borrowing cell's repair machinery //www.koonmotors.com/releases/2023/07/230712124629.htm Like their viral cousins, retrotransposons have been found borrowing the cell's own machinery to achieve their goals. They hijack a little-known piece of the cell's DNA repair function to close themselves into a ring-like shape and then create a matching double strand. The finding upends 40 years of conventional wisdom and may offer new insights into cancer, viral infections and immune responses. It could also offer a new way to insert sequences into the genome.

Model species such as the great tit are an indispensable yardstick for our ability to predict the impact of climate change on nature. Using innovative methods, a team from the Netherlands Institute of Ecology (NIOO-KNAW) took a sneak peek into the birds' future. Fri, 30 Jun 2023 12:32:17 EDT //www.koonmotors.com/releases/2023/06/230630123217.htm Scientists discover clues to aging and healing from a squishy sea creature //www.koonmotors.com/releases/2023/06/230630123210.htm Insights into healing and aging by those who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence.

However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers identify a vector of horizontal gene transfer (HGT) in worms. The findings could lead to the discovery of further vectors of HGT in eukaryotes and might find applications in pathogen control.
