Discovering Van Gogh in the wild: scientists unveil a new gecko species

Discovering Van Gogh in the wild: scientists unveil a new gecko species
2024-03-28
(Press-News.org) You’ve probably seen nature depicted in art, but how often do you see an artwork hiding in nature?

When they saw the back of a lizard in the Southern Western Ghats, a group of scientists from the Thackeray Wildlife Foundation in India were reminded of Van Gogh’s The Starry Night. As soon as they figured out it was a new species, it was only apt to name it in honour of the famous painter.

“Cnemaspis vangoghi is named for Dutch painter Vincent Van Gogh (1853–1890) as the striking colouration of the new species is reminiscent of one of his most iconic paintings, The Starry Night,” explains Ishan Agarwal, who took part in the  study to describe the new lizard. Males of the species have a yellow head and forebody and light blue spots on the back and they live among rocks and occasionally buildings and trees.

Together with his fellow researchers Akshay Khandekar and Tejas Thackeray, they found the new species during an expedition in April 2022 to the the Southern Western Ghats in Tamil Nadu, India. Now, they have published their findings in the peer-reviewed journal ZooKeys.

“Tamil Nadu is an exceptionally biodiverse state and we expect to name well over 50 new species of lizards by the time we are done [with our expeditions]!,” Ishan Agarwal says.

“I also had more than 500 tick bites during that summer trip, with the highest densities in the low-elevation, dry forests of Srivilliputhur, where the new species are found,” he adds.

Cnemaspis vangoghi is a small-sized gecko that can reach 3,4 cm in length. It was described as new to science together with another species of its genus, Cnemaspis sathuragiriensis, named for its type locality the Sathuragiri Hills.

 “The two new species are distributed in low elevation (250–400 m asl.), deciduous forests of Srivilliputhur, and add to the five previously known endemic vertebrates from Srivilliputhur-Megamalai Tiger Reserve, Tamil Nadu, India,” Ishan Agarwal explains. They are diurnal and mainly active during the cool hours of the early morning and evening, found largely on rocks. So far, they have only been found in very restricted localities, “an interesting case of micro-endemism in low-elevation species,” he notes.

Small birds spice up the already diverse diet of spotted hyenas in Namibia

Small birds spice up the already diverse diet of spotted hyenas in Namibia
2024-03-28
Hyenas are generalist predators (and scavengers) with a broad range of prey species. They are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey is a strategy of generalists – and this even extends to small passerine birds, as scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the University of Ljubljana observed in Namibia: Spotted hyenas pursued red-billed queleas, picked them from the ground or the surface of a waterhole and swallowed them whole, at a success rate of approximately one bird every three minutes. These observations were described ...

Imaging detects transient “hypoxic pockets” in the mouse brain

2024-03-28
Using a bioluminescent oxygen indicator, Felix Beinlich and colleagues discovered a spontaneous, spatially defined occurrence of “hypoxic pockets” in the mouse brain. Their technique offers a way to learn more about brain oxygen tension (pO2), a measure of oxygen delivery and demand in brain tissue that changes dynamically but is not well understood. The findings could have implications for how rest and exercise affect pO2 in the human brain, including the role of these activities in conditions such as dementia, Beinlich et al. suggest. The researchers used a genetically encoded bioluminescent oxygen indicator called Green NanoLuc in mouse cortical astrocytes to ...

Dissolved organic matter could be used to track and improve the health of freshwaters

2024-03-28
The dissolved organic matter (DOM) from hundreds of plant and animal remains could be used to track and possibly restore the health of freshwater bodies, Andrew J. Tanentzap and Jérémy A. Fonvielle write in this Perspective. The broad range of compounds, or chemodiversity, of DOM has multiple effects in freshwaters, including providing nutrients to support food web productivity, reducing or enhancing contamination from pollutants, and influencing the metabolism of microorganisms important to the biogeochemical cycle. DOM may also reduce the heat that ...

Indoor air quality standards in public buildings would boost health and economy, say international experts

2024-03-28
There should be mandatory indoor air quality standards, say an international group of experts led by Professor Lidia Morawska.   Professor Morawska, Vice-Chancellor Fellow at the University of Surrey and Distinguished Professor at Queensland University of Technology, led the appeal to the World Health Organization to recognise the airborne transmission of the virus which causes COVID-19 early in the pandemic – and help minimise it.   Now, in a paper published by the prestigious journal Science, Professor Morawska's international team recommends setting standards for ventilation rate and three key indoor pollutants: carbon ...

Positive associations between premenstrual disorders and perinatal depression

Positive associations between premenstrual disorders and perinatal depression
2024-03-28
Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to research published March 28th in the open access journal PLOS Medicine. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrual disorders after pregnancy and childbirth. This study suggests that a common mechanism might contribute to the two conditions. Menstruating women experience cyclical hormone fluctuations through puberty, menstrual cycle, pregnancy ...

New imaging method illuminates oxygen's journey in the brain

New imaging method illuminates oxygens journey in the brain
2024-03-28
The human brain consumes vast amounts of energy, which is almost exclusively generated from a form of metabolism that requires oxygen. Consequently, the efficient and timely allocation and delivery of oxygen is critical to healthy brain function, however, the precise mechanics of this process have largely remained hidden from scientists.    A new bioluminescence imaging technique, described today in the journal Science, has created highly detailed, and visually striking, images of the movement ...

Researchers discover key gene for toxic alkaloid in barley

2024-03-28
All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley, one of the world’s most widely grown cereals. Gramine provides protection against herbivorous insects and grazing animals and inhibits the growth of other plants. Despite long-standing interest, the key gene for the formation of gramine remained elusive. The researchers discovered a cluster of two genes in barley for gramine biosynthesis. The first gene (HvNMT) had already been discovered 18 years ago. In their study the researchers from IPK and the Leibniz University Hannover now identified a second gene (AMI synthase, HvAMIS), and ...

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects
2024-03-28
The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada. Microparticles from car tyres, pesticides from farmers’ fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach, which also indicates the impact these chemicals are likely to have in a particular river or lake. Importantly, the approach can also point to the origin of specific organic matter dissolved in the water, because it has a distinct ...

Bidirectional link between premenstrual disorders and perinatal depression

2024-03-28
Women with premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) have a higher risk of perinatal depression. Conversely, women with perinatal depression have a higher risk of developing premenstrual disorders. This is shown in a study from Karolinska Institutet published in the journal PLOS Medicine. Premenstrual disorders like PMS or PMDD and perinatal depression are similar in the way that symptoms appear in connection with hormonal changes. This fact has given rise to the hypothesis ...

Cell division quality control ‘stopwatch’ uncovered

Cell division quality control ‘stopwatch’ uncovered
2024-03-28
Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells. It’s during this crucial period of cell division that things can go haywire. Chromosomes can be misdirected, leading to damaged and diseased cells that progress to different types of cancer. University of California San Diego scientists reporting in the journal Science have found a key mechanism that keeps track of mitosis timing and ...
