Nash A new study finds that attine ants developed structural adaptations to host bacteria, specifically Pseudonocardia, which aids their fungal farming. A study explores the evolution of beneficial bacteria residing within and on the surface of farming ants. Attine ants engage in a mutualistic relationship by cultivating fungi, one of the most extensively studied symbioses in nature. In the 1990s, researchers discovered an additional partner in this relationship: an actinobacterium known as Pseudonocardia. This bacterium inhabits the ants’ cuticle—their protective exoskeleton—where it is nourished by secretions from subcuticular glands. Pseudonocardia is known to kill the fungal pathogen Escovopsis, that might destroy the ants’ mutualistic fungus. Jacobus J. Boomsma and colleagues sequenced samples from 194 ants from 11 attine species collected in Panama to assess the extent of coevolution between ants and their cuticular residents. Three of the 11 attine species had abundant Pseudonocardia, including two Acromyrmex leaf-cutting ants. Five other species had cuticular actinobacteria other than Pseudonocardia, with no clear phylogenetic patterns. Insights into Ant Gland Structure and Function The authors examined the ants’ nourishment glands with transmission electron microscopy, revealing similar structures across species, suggesting that attine ants evolved structural and functional adaptations for hosting cuticular actinobacteria only once, shortly after the origin of fungus farming. Clearly, however, the glands are capable of nourishing bacterial strains other than Pseudonocardia. Comparing phylogenies of ants and their cuticular and gut Pseudonocardia indicates that Pseudonocardia were initially gut symbionts and became cuticular symbionts late in attine evolution, around 20 million years ago, coincident with the evolution of new genera in Central/North America. According to the authors, earlier contradictory findings can be explained by not separating guts and cuticles during sequencing, and because ants easily acquire non-natural actinobacteria when held for longer periods in lab settings.

Tiger Sharks New research indicates that baited shark diving can influence tiger shark social behavior. Scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science (UM) and the Institute of Zoology at the Zoological Society London (ZSL) found that tiger sharks, often considered a solitary nomadic species, are social creatures, having preferences for one another.  A first of its kind, the study also evaluated if exposure of the tiger shark to baited dive tourism impacted their social behavior. The study was conducted at a site named Tiger Beach, located off the north-west side of Little Bahama bank in the Bahamas. The area is known for hosting shark diving encounters, where the sharks are attracted with chum and often fed in front of dive tourists. Baited shark dives are often conducted by dive tourism companies to attract the animals so that tourists may observe them. This approach has been known to cause mixed feelings among conservationists and shark experts, due to the possible long-term impacts on the predators, such as changes to their natural foraging behavior. This study found that tiger sharks aggregated at the dive sites, but social preferences between sharks were less prevalent as compared to areas outside of these dive sites. These results suggest that feeding sharks may disrupt their social organization, but only temporarily, as the study found that tiger sharks resumed their social groupings outside of the dive sites. Credit: University of Miami Rosenstiel School of Marine and Atmospheric Science The research team tagged and tracked the movements of tiger sharks over the course of three years. They then applied a tool called Social Network Analysis to the tracking data to examine if tiger sharks exhibited social grouping behavior and if this social behavior differed at locations where sharks were exposed to baited shark dive tourism. The study not only found that tiger sharks formed social groups, but also discovered that at sites where tiger sharks were being fed by dive tourism operators, tiger sharks became more aggregated, but interactions between sharks became more random, suggesting a breakdown in social organization. “Given that tiger sharks spend months at a time out in the open ocean as solitary predators, it’s amazing to me that they show social preferences for one another when they are at the Tiger Beach area,” said Neil Hammerschlag, senior author of the study and research associate professor at the UM Rosenstiel School. “For nearly two decades, I have spent countless hours diving at Tiger Beach, always wondering if these apex predators interacted socially. Now we know.” Tiger sharks form social groups at sites where they are fed by dive tourism operators.

The social behavior of predators is an important area of study as it provides another tool to help scientists and wildlife managers build a picture of how they live, what drives them to form social groups, and the roles they play within the wider ecosystem.  Reference: “Social Network Analysis Reveals the Subtle Impacts of Tourist Provisioning on the Social Behavior of a Generalist Marine Apex Predator” by David M.

Credit: Tania Jogesh Study of Flowers With Two Types of Anthers Solves Mystery That Baffled Darwin Some flowers use a clever strategy to ensure effective pollination by bees, doling out pollen gradually from two different sets of anthers. Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in pollen as a food source. “The bee and the plant have different goals, so plants have evolved ways to optimize the behavior of bees to maximize the transfer of pollen between flowers,” explained Kathleen Kay, associate professor of ecology and evolutionary biology at UC Santa Cruz. Close-up photos of Clarkia unguiculata and Clarkia cylindrica flowers show the two types of anthers, a conspicuous inner whorl and an outer whorl that blends in with the petals. Credit: Kay et al., PRSB 2020 In a study published December 23 in Proceedings of the Royal Society B, Kay’s team described a pollination strategy involving flowers with two distinct sets of anthers that differ in color, size, and position. Darwin was mystified by such flowers, lamenting in a letter that he had “wasted enormous effort over them, and cannot yet get a glimpse of the meaning of the parts.” For years, the only explanation put forth for this phenomenon, called heteranthery, was that one set of anthers is specialized for attracting and feeding bees, while a less conspicuous set of anthers surreptitiously dusts them with pollen for transfer to another flower. This “division of labor” hypothesis has been tested in various species, and although it does seem to apply in a few cases, many studies have failed to confirm it. A New Theory: Pollen Dosing Over Time The new study proposes a different explanation and shows how it works in species of wildflowers in the genus Clarkia. Through a variety of greenhouse and field experiments, Kay’s team showed that heteranthery in Clarkia is a way for flowers to gradually present their pollen to bees over multiple visits. “What’s happening is the anthers open at different times, so the plant is doling out pollen to the bees gradually,” Kay said. This “pollen dosing” strategy is a way of getting the bees to move on to another flower without stopping to groom the pollen off their bodies and pack it away for delivery to their nest. Bees are highly specialized for pollen feeding, with hairs on their bodies that attract pollen electrostatically, stiff hairs on their legs for grooming, and structures for storing pollen on their legs or bodies. Bee Behavior and Floral Strategy “If a flower doses a bee with a ton of pollen, the bee is in pollen heaven and it will start grooming and then go off to feed its offspring without visiting another flower,” Kay said. “So plants have different mechanisms for doling out pollen gradually. In this case, the flower is hiding some anthers and gradually revealing them to pollinators, and that limits how much pollen a bee can remove in each visit.” There are about 41 species of Clarkia in California, and about half of them have two types of anthers. These tend to be pollinated by specialized species of native solitary bees. Kay’s team focused on bee pollination in two species of Clarkia, C. unguiculata (elegant clarkia) and C. cylindrica (speckled clarkia). A Step-by-Step Bloom: Inner and Outer Anthers In these and other heterantherous clarkias, an inner whorl of anthers stands erect in the center of the flower, is visually conspicuous, and matures early, releasing its pollen first. An inconspicuous outer whorl lies back against the petals until after the inner anthers have opened. The outer anthers then move toward the center of the flower and begin to release their pollen gradually. A few days later, the stigma becomes erect and sticky, ready to receive pollen from another flower. “In the field, you can see flowers in different stages, and using time-lapse photography we could see the whole sequence of events in individual flowers,” Kay said. The division of labor hypothesis requires both sets of anthers to be producing pollen at the same time. Kay said she decided to investigate heteranthery after observing clarkia flowers at a field site and realizing that explanation didn’t fit. “I could see some flowers where one set was active, and some where the other set was active, but no flowers where both were active at the same time,” she said. In C. cylindrica, the two sets of anthers produce pollen with different colors, which enabled the researchers to track where it was going. Their experiments showed that pollen from both sets of anthers was collected for food and was also being transferred between flowers, contradicting the division of labor hypothesis. “The color difference was convenient, because otherwise it’s very hard to track pollen,” Kay said. “We showed that bees are collecting and transporting pollen from both kinds of anthers, so they are not specialized for different functions.” Kay said she didn’t realize how much time Darwin had spent puzzling over heteranthery until she started studying it herself. “He figured out so many things, it’s hard to find a case where he didn’t figure it out,” she said. Darwin might have been on the right track, though. Shortly before his death, he requested seeds of C. unguiculata to use in experiments.
