Hypoxic ocean waters are those that have little to no oxygen. These conditions can impact both coral reef and microbial communities, such as the one pictured beneath the sea surface here. This is a view of the surface waters off the coast of a Bocos del Toro island. Credit: Maggie Johnson © Woods Hole Oceanographic Institution In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral. This unique observation prompted a collaborative study explained in a new paper published on July 26, 2021, in Nature Communications analyzing what this foggy water layer is caused by, and the impact it has on life at the bottom of the seafloor. Brittle sea stars, which usually are in hiding, perch on top of andcoral to attempt to escape from hypoxic ocean waters, which have little to no oxygen in that area. Sadly, those that cannot escape essentially suffocate.

All of the macro-organisms are trying to get away from this deoxygenated water, and those that cannot escape essentially suffocate. I have never seen anything like that on a coral reef,” said Johnson. The study looks closely at the changes occurring in both coral reef and microbial communities near Bocas del Toro during sudden hypoxic events. When water drops below 2.8mg of oxygen per liter, it becomes hypoxic. More than 10% of coral reefs around the world are at high risk for hypoxia (Altieri et al. 2017- tropical dead zones and mass mortalities on coral reefs).

Credit: Maggie Johnson © Woods Hole Oceanographic Institution “There is a combination of stagnant water from low wind activity, warm water temperatures, and nutrient pollution from nearby plantations, which contributes to a stratification of the water column. From this, we see these hypoxic conditions form that start to expand and infringe on nearby shallow habitats,” explained Johnson. Investigators suggest that loss of oxygen in the global ocean is accelerating due to climate change and excess nutrients, but how sudden deoxygenation events affect tropical marine ecosystems is poorly understood. Past research shows that rising temperatures can lead to physical alterations in coral, such as bleaching, which occurs when corals are stressed and expel algae that live within their tissues. If conditions don’t improve, the bleached corals then die. However, the real-time changes caused by decreasing oxygen levels in the tropics have seldom been observed.

Credit: Maggie Johnson © Woods Hole Oceanographic Institution At a local scale, hypoxic events may pose a more severe threat to coral reefs than the warming events that cause mass bleaching. These sudden events impact all oxygen-requiring marine life and can kill reef ecosystems quickly. Investigators reported coral bleaching and mass mortality due to this occurrence, causing a 50% loss of live coral, which did not show signs of recovery until a year after the event, and a drastic shift in the seafloor community. The shallowest measurement with hypoxic waters was about 9 feet deep and about 30 feet from the Bocas del Toro shore. What about the 50% of coral that survived? Johnson and her fellow investigators found that the coral community they observed in Bocas del Toro is dynamic, and some corals have the potential to withstand these conditions. This discovery sets the stage for future research to identify which coral genotypes or species have adapted to rapidly changing environments and the characteristics that help them thrive.

By collecting sea water samples and analyzing microbial DNA, they were able to conclude that these microbes did not necessarily adjust to their environment, but rather were “waiting” for their time to shine in these low-oxygen conditions. When marine life is exposed to hypoxic waters, the conditions can sometimes be very harmful.

Credit: Maggie Johnson © Woods Hole Oceanographic Institution “The take home message here is that you have a community of microbes; it has a particular composition and plugs along, then suddenly, all of the oxygen is removed, and you get a replacement of community members. They flourish for a while, and eventually hypoxia goes away, oxygen comes back, and that community rapidly shifts back to what it was before due to the change in resources. This is very much in contrast to what you see with macro-organisms,” said Jarrod Scott, paper co-author and postdoctoral fellow at the Smithsonian Tropical Research Institute in the Republic of Panama. Scott and Johnson agree that human activity can contribute to the nutrient pollution and warming waters which then lead to hypoxic ocean conditions. Activities such as coastal land development and farming can be better managed and improved, which will reduce the likelihood of deoxygenation events occurring. The study provides insight to the fate of microbe communities on a coral reef during an acute deoxygenation event. Reef microbes respond rapidly to changes in physicochemical conditions, providing reliable indications of both physical and biological processes in nature. The shift the team detected from the hypoxic microbial community to a normal condition community after the event subsided suggests that the recovery route of reef microbes is independent and decoupled from the benthic macro-organisms. This may facilitate the restart of key microbial processes that influence the recovery of other aspects of the reef community.

A Penn State study suggests that giraffes’ long necks may have evolved due to the high nutritional needs of females, who require deep foraging into trees for food. While the “necks-for-sex” hypothesis posits that male competition drove neck length evolution, findings show females have proportionally longer necks. This research, published in Mammalian Biology, highlights the importance of conserving giraffe habitats to support their unique ecological needs. Penn State research indicates that female giraffes’ long necks, crucial for accessing deep-set leaves, might drive their evolution, highlighting the need for conservation efforts. Why do giraffes have long necks? A new study by biologists from Penn State examines the evolutionary development of this distinctive feature, providing fresh insights into a classic question. While the prevailing theory attributes the long necks to male competition, the researchers observed that female giraffes actually have proportionally longer necks compared to males. This suggests that the high nutritional demands of females might have been a key factor in the evolution of the giraffe’s long neck. The study, which explored body proportions of both wild and captive giraffes, is described in a paper that was recently published in the journal Mammalian Biology. The findings, the team said, indicate that neck length may be the result of females foraging deeply into trees for otherwise difficult-to-reach leaves. Evolutionary Theories and Observations In their classic theories of evolution, both Jean Baptiste Lamarck and Charles Darwin suggested that giraffes’ long necks evolved to help them reach leaves high up in a tree, avoiding competition with other herbivores. However, a more recent hypothesis called “necks-for-sex” suggests that the evolution of long necks was driven by competition among males, who swing their necks into each other to assert dominance, called neck sparring. That is, males with longer necks might have been more successful in the competition, leading to reproducing and passing their genes to offspring. “The necks-for-sex hypothesis predicted that males would have longer necks than females,” said Doug Cavener, Dorothy Foehr Huck and J. Lloyd Huck Distinguished Chair in Evolutionary Genetics and professor of biology at Penn State and lead author of the study. “And technically they do have longer necks, but everything about males is longer; they are 30% to 40% bigger than females. In this study, we analyzed photos of hundreds of wild and captive Masai giraffes to investigate the relative body proportions of each species and how they might change as giraffes grow and mature.” Although male and female giraffes have the same body proportions at birth, they are significantly different as they reach sexual maturity. Females have proportionally longer necks and longer bodies than males, which might help with foraging and child-rearing, while males have wider necks and longer front legs, which might help win fights against other males and with mating. Credit: Penn State The researchers gathered thousands of photos of captive Masai giraffes from the publicly accessible photo repositories Flickr and SmugMug as well as photos of wild adult animals that they have taken over the past decade. Because absolute measurements like overall height are difficult to determine from a photograph without a point of reference of known length, the researchers instead focused on measurements relative to one another, or body proportions — for example, the length of the neck relative to the entire height of the animal. They restricted their analysis to images that met strict criteria, such as only using images of giraffes perpendicular to the camera, so they could consistently take a variety of measurements. “We can identify individual giraffes by their unique spot pattern,” Cavener said. “Thanks to the Association of Zoos and Aquariums, we also have the full pedigree, or family tree, of all Masai giraffes in North America in zoos and wildlife parks, as well as their birthdates and transfer history. So, by carefully considering this information, when the photo was taken and the approximate age of the animal, we could identify the specific individual in nearly every photo of a captive giraffe. This information was critical to understanding when male and female giraffes start to exhibit size differences and whether they grow differently.” Findings on Growth and Maturity At birth, male and female giraffes have the same body proportions. The researchers found that, although males generally grow faster in the first year, body proportions are not significantly different until they start to research sexual maturity around three years of age. Because body proportions change early in life, the team limited their study of wild animals — whose ages are largely unknown — to fully grown adults. In adult giraffes, the researchers found that females have proportionally longer necks and trunks — or the main section of their body, which does not include legs or the neck and head. Adult males, on the other hand, have longer forelegs and wider necks. This pattern was the same in both captive and wild giraffes. “Rather than stretching out to eat leaves on the tallest branches, you often see giraffes — especially females — reaching deep into the trees,” Cavener said. “Giraffes are picky eaters — they eat the leaves of only a few tree species, and longer necks allow them to reach deeper into the trees to get the leaves no one else can. Once females reach four or five years of age, they are almost always pregnant and lactating, so we think the increased nutritional demands of females drove the evolution of giraffes’ long necks.” The researchers noted that sexual selection — either competition among males or preference among females for larger mates — was likely responsible for the overall size difference between males in females, as is the case in many other large, hoofed mammals that are polygynous — where one male mates with many females. They suggest that, following the evolution of the long neck, sexual selection — including male body pushing and neck sparring behaviors — may have contributed to males’ wider necks. Additionally, the longer forelegs of males may assist in mating, which the researchers said is a brief and challenging affair that is rarely observed. “Interestingly, giraffes are one of few animals whose height we measure to the top of the head — like humans — rather than to their withers—the highest part of the back, like in horses and other livestock,” Cavener said. “The female has a proportionally longer axial skeleton — a longer neck and trunk — and are more sloped in appearance, while the males are more vertical.” The research team is also using genetics to identify relationships in groups of wild giraffes to better understand which males are successful at breeding. The goal is to shed additional light on mate choice and sexual selection, as well as guide conservation efforts for this endangered species. “If female foraging is driving this iconic trait as we suspect, it really highlights the importance of conserving their dwindling habitat,” Cavener said. “Populations of Masai giraffes have declined rapidly in the last 30 years, in part due to habitat loss and poaching, and it is critical that we understand the key aspects of their ecology and genetics in order devise the most efficacious conservation strategies to save these majestic animals.” Reference: “Sexual dimorphisms in body proportions of Masai giraffes and the evolution of the giraffe’s neck” by Douglas R.

Migratory bats pick up crucial environmental signals for long-distance navigation through the cornea of their eyes. Mammals see with their eyes, hear with their ears, and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), published together with Prof. Richard A. Holland (Bangor University, UK) and Dr. Gunārs Pētersons (Latvia University of Life Sciences and Technologies) now show that the cornea of the eyes is the location of such an important sense in migrating bats. If the cornea is anesthetized, the otherwise reliable sense of orientation is disturbed while light detection remains unimpaired. The experiment suggests the localization of a magnetic sense in mammals. The paper is published in the scientific journal Communications Biology. A research team led by Dr. Oliver Lindecke and PD Dr. Christian Voigt from Leibniz-IZW demonstrated for the first time that environmental signals that are important for navigating over long distances are picked up via the cornea of the eyes. They conducted experiments with Nathusius’ bats (Pipistrellus nathusii) during the late summer migration period. In bats of one test group, the scientists locally anesthetized the cornea with a drop of oxybuprocaine. This surface anesthetic is widely used in ophthalmology, where it is used to temporarily desensitize the patients’ cornea when eyes of humans or animals get overly irritated. Effects on orientation, however, had not been previously recorded. In another test group of bats, the research team anesthetized the cornea of only one eye. The individuals in the control group were not anesthetized, but instead received an isotonic saline solution as eye drops. All animals in this scientific experiment were captured within a migration corridor at the coastline of the Baltic Sea and released singly in the open field 11 kilometers inland from the capture site immediately after treatment.

Credit: Photo by Oliver Lindecke The scientists first used bat detectors to make sure that there were no other bats above the field at the time of release that the test animals could have followed. The person observing the direction of movement of released bats was unaware of how bats were treated experimentally. “The control group and the group with unilateral corneal anesthesia oriented themselves clearly in the expected southerly directions, whereas the bats with bilateral anesthetized corneas flew off in random directions,” explains Dr. Oliver Lindecke, first author of the paper. “This evident difference in behavior suggests that corneal anesthesia disrupted a sense of direction, yet orientation apparently still works well with one eye.” As corneal treatment wears off after a short time, the bats were able to resume their journeys south after the experiment. “We observed here for the first time in an experiment how a migrating mammal was literally blown off course — a milestone in behavioral and sensory biology that allows us to study the biological navigation system in a more targeted way.” In order to rule out the possibility that the anaesthetization of the cornea also affects the sense of sight and that the scientists would thus come to the wrong conclusions, they carried out a complementary test. Once again divided into experimental and control groups, they tested whether the response of bats to light changed after anesthesia of the corneas on one or both sides. “We know from previous research that bats prefer an illuminated exit when leaving a simple Y-shaped labyrinth,” explains PD Dr. Christian Voigt, head of the Leibniz-IZW Department of Evolutionary Ecology. “In our experiment, the animals with one-sided or two-sided anesthesia also showed this preference; we, therefore, can rule out that the ability to see light was altered after corneal treatment. The ability to see light would of course also influence long-distance navigation.” Many vertebrates such as bats, dolphins, whales, fish, and turtles, for example, are able to safely navigate in the darkness, whether it is under the open night sky, when it is cloudy at night or in caves and tunnels as well as in the depths of the oceans. For many decades, scientists have been searching for the sense or a sensory organ that enables animals to perform orientation and navigation tasks that seemed difficult to imagine for people. A magnetic sense, so far only demonstrated in a few mammals but poorly understood, is an obvious candidate. Experiments suggest that iron oxide particles within cells may act as “microscopic compass needles,” as is the case in some species of bacteria. Recent laboratory experiments on Ansell’s mole-rat, relatives of the well-known naked mole rats that spend their lives in elaborate underground tunnel systems, suggest that the magnetic sense is located in the eye. Such a (magnetic) sense of orientation has not been checked in migratory mammals nor has it been possible to identify the specific organ or tissue which could provide the morphological basis for the required sensory receptors. The experiments of the team around Lindecke and Voigt now provide, for the first time, reliable data for the localization of a sense of orientation in free-ranging, migratory mammals. Exactly what the sense in the cornea of the bats looks like, how it works, and whether it is the long sought-after magnetic sense must be shown in future scientific investigations.
