Painted by nature, printed by artists

This article brings the 17th-century Dutch painter Otto Marseus van Schrieck and the contemporary German artist Maximilian Prüfer into dialogue. It investigates in particular Marseus’ and Prüfer’s use of butterfly scales as materials and motifs in their works of art. Both artists developed a similar technique of butterfly imprints (lepidochromy), which consists of transferring the scales of real butterflies onto another surface. The imprints thus combine medium with representation and the object being represented. The artists used a variety of animal substances to make their artworks, some still visible, some not, and gathered living animals to depict after life or to work with in other ways. Knowledge of and interest in natural history inform the work of both artists but their reflections on human relationships with other animals and with ‘nature’ differ.

Food capture and escape behavior of Leposternon microcephalum Wagler, 1824 (Squamata: Amphisbaenia)

Amphisbaenians are fossorial reptiles that have a cylindrical and elongated body covered with scales arranged in rings, and are all apodal, except for the three species of the genus Bipes. The amphisbaenian diet consists of a variety of invertebrates and small vertebrates. As these animals live underground, many aspects of their natural history are difficult to study. Most feeding studies of amphisbaenians have focused on the composition of the diet and feeding ecology, and the data available on feeding behavior are based on precursory observations. The present study describes the food capture behavior of Leposternon microcephalum Wagler, 1824 in captivity. In this experiment we used non-live bait (moist cat food), which was placed near a burrow opening, on the surface of the substrate. Three animals were monitored visually and filmed using cellphone cameras deployed at fixed points, to capture images from the dorsal and lateral perspectives of the study subjects. Two principal types of behavior were observed: the capture of food and defense mechanisms. The strategies used to capture the food were similar to those observed in other fossorial species. Although the backward movement has already been observed and described, we were able to record this movement being used as an escape strategy. These findings enrich our knowledge on different aspects of the natural history of the amphisbaenians.

The Wryneck

This book details the natural history and cultural symbolism of a most unusual woodpecker – a species that neither excavates nest holes in trees, nor bores into wood to find insect prey. The elusive Wryneck is best renowned for performing a twisting, writhing head and neck display when threatened, but this ground-breaking study reveals many more secrets of its behaviour and evolution. Detailed information is presented on the species' origins, taxonomy, anatomy, appearance, moult, calls, distribution, conservation status, habitats, movements, breeding, diet and relationships, along with a chapter on its closest relative, the Red-throated Wryneck. The text is richly illustrated throughout with high quality photographs as well as sound spectrograms. This all-encompassing and engaging account has been written for a wide audience, whether professional ornithologist, citizen scientist, amateur birder, woodpecker aficionado and simply someone who wishes to learn more about this curious and remarkable bird.

Understanding Mentoring Style of Mentors and Science Identity Formation in Historically Excluded Undergraduate Students in Natural History Collections

Background: Science identity formation is integral to the transformation from a student to a member of the STEM workforce. However, the formation of a student’s science identity is affected by various factors such as support from mentors and community members, the student’s perception of their peers’ acceptance of them, as well as the student’s own perception of their role in research. The aim of this study is to investigate mentors’ understanding of science identity formation, their mentoring style, and if it is effective when working with students from historically excluded populations. A phenomenological approach was used to conduct this study. Structured interviews were conducted with natural history collections faculty members of various backgrounds and career levels. Results: Three themes emerged that contribute to science identity formation through mentoring: 1. Factors for science identity formation; 2. Mentorship among different career stages, and 3. Defining own mentoring style. Predominantly, participants realized that their own experience as a mentee shapes how they approach mentoring.Conclusions: Although this study describes the mentee’s science identity formation from the mentor’s point of view, the study’s participants realized the importance they play in a student’s science identity formation, and that mindful mentoring is necessary for success when engaging historically excluded groups in the STEM workforce.

Natural History of Model Organisms: The big potential of the small frog Eleutherodactylus coqui

The Puerto Rican coquí frog Eleutherodactylus coqui (E. coqui) is both a cultural icon and a species with an unusual natural history that has attracted attention from researchers in a number of different fields within biology. Unlike most frogs, the coquí frog skips the tadpole stage, which makes it of interest to developmental biologists. The frog is best known in Puerto Rico for its notoriously loud mating call, which has allowed researchers to study aspects of social behavior such as vocal communication and courtship, while the ability of coquí to colonize new habitats has been used to explore the biology of invasive species. This article reviews research on the natural history of E. coqui and opportunities for future research.

Cardiovascular manifestations of Hutchinson–Gilford progeria syndrome

Cardiovascular complications are the most frequent cause of death in patients with the Hutchinson–Gilford progeria syndrome. However, due to its rarity, studying the course of cardiac abnormalities has been a challenge. The cardiovascular phenotype helps to provide greater insight into the natural history of these abnormalities.

Living near water: Ecological observations on the Ecuador Sipo, Chironius grandisquamis, (Peters 1869) (Serpentes: Colubridae), in the Middle Magdalena River Valley, Colombia

More than 40 species of snakes inhabit the humid forests of the Middle Magdalena River Basin of Colombia, yet studies on the basic aspects of snake ecology and natural history in this region are scarce. We searched for Ecuador Sipos (Chironius grandisquamis) during six years (2014–2019) of 6–24-day visual-encounter surveys by day and night in both rainy and dry periods. In 2,967 person-hours, we recorded 16 individuals, half during rainy and half during dry periods. Fourteen of the 16 encounters were in the evening and two in the morning. Snakes recorded during the day were foraging on the ground, whereas those recorded at night were inactive and perched in vegetation. Most inactive individuals had selected perches along streams flanked by riparian forests; ten were in shrubs and four in trees on branches 120–600 cm above the ground. We also record predation on a northern rainfrog (Craugastor metriosistus) on the forest floor during the day.
