October 10, To help determine forest restoration goals in Costa Rica, postdoctoral scholar Rachel Reid will travel to Central America this winter to explore a cave long inhabited by bats. What did the Costa Rican landscape look like thousands of years ago? A team of Saint Louis researchers is hoping that bat guano will help them answer that question. Armed with peat borers and insect traps, a team of researchers led by Rachel Reid, a postdoctoral scholar in the Department of Anthropology, will travel to Central America this winter to explore a cave long inhabited by bats. The scientists plan to use biochemical signatures preserved in bat guano to understand how vegetation coverage has changed over the past several thousand years. Instead, Reid’s team will look at biochemical signatures preserved in caves, which naturally shield their contents from much of the rainforest’s heat and humidity. Their field site, Bajo los Indios Cave, has housed a type of insect-eating bat known as Parnell’s mustached bat Pteronotus parnellii for millennia — which means the cave also has a cache of bat guano, the remains of insects digested by the bats, dating back thousands of years.

Benjamin Horton remembers being in Southeast Asia just months after the devastating Indian Ocean tsunami. Horton, who studies sea levels at Rutgers University and Nanyang Technological University , was just one of dozens of researchers who came in search of answers: Had this happened before? Would it happen again? The answers were certainly not to be found in written records or seismometer data.
In the short time such data have existed for the Indian Ocean, no one had ever recorded an earthquake capable of sending such a huge wall of water crashing into the coast. The tsunami in was so deadly because it was so unexpected. The answer, if scientists were to find it, would probably be in sand. Tsunamis pick up sand from the depths of the ocean floor, depositing it on land as the waters recede. Low-lying coastal plains are good places to look.
So are lagoons or mangrove swamps that trap sand. A number of such sites around the Indian Ocean have allowed scientists to begin piecing together a fragmentary history of Indian Ocean tsunamis.
Cave under Predjama Castle
And I asked it twice. I later discovered that most people who visit the bat-filled cave have the same dual query. First-time visitors arrive excited and anxious for the bats to emerge. The question fades when the cyclone of bats begins to whirl up from the cave and into the sky. The answer: No one knows. But stories from long-ago guano miners suggest the back end of the cave was dug down 30 to 60 feet 9 to 18 meters without reaching the bottom of the guano.
We will return to Bat Cave when we look at the impact of a new revolution in radiocarbon dating. In spite of the early dates attributed to the maize found at Bat.

Archaeological finds in the cavern behind the Predjama Castle testify to the fact that the cave was inhabited by humans in as early as the Stone Age. Remains from the Roman times were found in the entrance section to the cave called the Stables, whereas the Cave of Names boasts signatures dating back to the 16th century. The Cave under Predjama Castle is the second longest Slovenian show cave spreading over four floors , which are all interconnected except for Erazem’s Hole and Erazem’s Passage on the top floor.
The total length of all the cave parts discovered so far is 14 kilometres. An excellent choice for more adventurous visitors is a tour of Erazem’s and Eastern Passages , as well as a guided walk to the Wind Hole. Adventure tours are intended for all visitors who would like to visit the cave sections that are closed to regular cave tours, experience more challenging cave passages, break through water barriers, and follow in the footsteps of cave explorers.
Miniopterus bassanii are exclusive cave residents, but bats may live in tree hollows, area in Germany dating to about Middle Eocene(about 50 million years).
Through their unique use of sophisticated laryngeal echolocation bats are considered sensory specialists amongst mammals and represent an excellent model in which to explore sensory perception. Although several studies have shown that the evolution of vision is linked to ecological niche adaptation in other mammalian lineages, this has not yet been fully explored in bats. Recent molecular analysis of the opsin genes, which encode the photosensitive pigments underpinning color vision, have implicated high-duty cycle HDC echolocation and the adoption of cave roosting habits in the degeneration of color vision in bats.
However, insufficient sampling of relevant taxa has hindered definitive testing of these hypotheses. The presence of UV vision in bats is supported by our spectral tuning analysis, but phylogenetic analyses demonstrated that the SWS1 opsin gene has undergone pseudogenization in several lineages. Pseudogenization of the SWS1 is correlated with cave roosting habits in the majority of pteropodid species. Together these results demonstrate that the loss of UV vision in bats is more widespread than was previously considered and further elucidate the role of ecological niche specialization in the evolution of vision in bats.
Bats possess some of the most unique and peculiar adaptations observed amongst extant mammals that render them as excellent models in which to study the evolution of sensory perception. In vertebrates, photosensitive molecules within the outer segments of rods and cones of the retina determine the spectral sensitivity of the eye.
Hpa-An, Myanmar: Holy Batcave!
In kernels of an early corn variety capable of being popped were found in an archaeological dig in a New Mexico rock shelter known as “Bat Cave”. These finds are widely reported as being the oldest ears of popcorn ever found; such reports often say they are dated to be years old, or more. The actual facts about the Bat Cave corn are less clear. While initial reports dated the corn to be years old, in the same researchers revealed data from more specifically targeted dating: a sample consisting only of cobs was dated to be 1, years old, and a sample of cobs and nearby wood 2, years.
These dates have been called into question as well: Michael S. Berry, after a study of the Bat Cave procedures, wrote it “was a poorly excavated site that can be interpreted nearly any way one pleases by juggling the data.
The cave walls are decorated by prehistoric cave paintings dating back about They are painted with bat guano (bat excrement) and represent.
They smell strangers when they approach. So we always know when there are intruders. That would have been useful in the years of Fiji’s vicious tribal wars because the huge cave Ratu was taking us to see was the place where the people of his Tau village have sought shelter for hundreds – possibly thousands – of years. Carbon dating of recent archaeological finds has indicated that Tau was one of the first places humans settled when they arrived in Fiji and the cave would have made a great home for people newly arrived in a strange land.
The steep access track, slippery from recent rain and in places squishy with fallen mangoes, certainly looked easy to defend. But once inside, the cave is surprisingly spacious, with a lofty vaulted limestone roof above a flat area lit by several openings where, according to Ratu, “the people went about their daily living, meeting each other, preparing food, cooking and eating”. He showed us a deep vomo pit “excavated by archaeologists from the university” strategically placed under one of the openings “so the smoke could go straight out and not suffocate the people”.
Next to it was a circle of stones which acted as the fireplace. Further into the cave, separated from the living area by a low stone barrier, was a smaller flat space “where children could play”.
Batman makes an unexpected cameo on Naked Attraction
It’s like Tanah Lot or Pura Besakih one of Bali’s key nine directional temples and serves particularly as a guardian against dark spirits from the ocean. Mpu Kuturan who was one of tha priests who laid the foundation for Hinduism on Bali founded the temple in the 11th century. Some shrines in the compound are still dating back to that early period. The Bat Cave temple is located at the south east coast of Bali, roughly 10km away from Klungkung, 10km south of Candidasa in the village of Pasinggahan.
It’s just beside the main road tot he eastern part of Bali such as Candidasa, Padangbai, Karangasem, Amlapura and next to a beautiful black sandy beach. From here you can see at the horizon the coast of Nusa Penida.
Quaternary cave deposits are known to exist (Des Marais et al., ; Mizutani et al., b; McFarlane et al., ;. Bird et al., ). To date, several studies.
Dudley News Published: Jul 14, A cave dating back to the 18th century has been boarded up sparking accusations that canal heritage is being destroyed. The Devils Den cave at Prestwood, near Kinver has been sealed to protect a bats’ nesting site and to prevent it being used by boozing yobs. It was once a boathouse. The estate was owned by the wealthy ironworking family of Foley of Prestwood House and as a condition of allowing the canal through their estate a boathouse was created in a sandstone cliff.
It is believed to have remained in use until the late s when the Foley family sold the estate. Since then it has been out of use until British Waterways decided to investigate it as a bat roosting site. The firm has now fitted an oak door at the entrance with a small gap in the top to allow the bats to fly in and out and says it did have permission from the owner of the cave Completelink Ltd.
We have had a lot of feedback from our members who are outraged that something that has been here for years has a had a nasty wooden door plonked across it. British Waterways spokeswoman Nicky Lister said: “The cave was clearly showing signs of anti-social behavior with discarded cans and bottles and drug paraphernalia. With the only access to the cave by the steep cliff above or by water, any attempts to enter could pose serious safety risks.

Two other radiocarbon dates impor- tant for the dating of Maiz de Ocho have been obtained on maize cobs from Bat. Cave, New Mexico (Arnold and Libby.
Although the caves were discovered in , they were not studied until The caves host one of the largest bat colonies in Andalusia. The rock formations and caves with stalactites, stalagmites and subterranean lakes were formed due to weathering and leaching of carbonate rocks. The caves have a total length of 2, metres, of which only metres can be accessed. Speleologists discovered tombs from the middle Paleolithic period, which show evidence of human occupation of the caves 35, years ago. According to the Carbon dating method, finds from the Neolithic period have an age from 4, to 3, BC.
The researchers reconstructed the lives of people whose artefacts were found preferentially at the cave entrance. Here they cooked their meals on an open firepit. Their diet consisted of the meat of wild and farm animals and various cereals. They used tools created of flint and bones, in order to cut leather. They manufactured red painted vessels, as well as necklaces and bracelets made of sea shells, which they probably acquired through trade with coastal residents.
Apparently, the group was on the transition from a live as hunter-gatherers to a live as farmers, who cultivated crops and bred domestic animals.

Note: This article contains graphic imagery which, uh, let’s just say may not be suitable for younger readers. Naked Attraction made its return to Channel 4 tonight August 21 and was graced by a surprising cameo from Batman — or at least his logo. With Anna Richardson returning as host, tonight’s episode saw year-old Stephanie, a self-confessed ‘dating disaster’, take her pick of six naked men.
Having whittled her selection down to warehouse supervisor Chris and train engineer Ashley, it was Stephanie’s turn to strip off, revealing her heavily tattooed body. But there was one piece of body art in particular that caught the attention of both her prospective dates — a Batman logo situated directly above her intimate region. Naturally, viewers couldn’t help but express their shock, or whatever the digital equivalent of spitting out your tea is.
