Histochemical Characteristics of Macrophages of Butterfly Splitfin Ameca Splendens
e-ISSN 1734-9168 Folia Biologica (Kraków), vol. 67 (2019), No 1 http://www.isez.pan.krakow.pl/en/folia-biologica.html https://doi.org/10.3409/fb_67-1.05 Histochemical Characteristics of Macrophages of Butterfly Splitfin Ameca splendens Ewelina LATOSZEK, Maciej KAMASZEWSKI , Konrad MILCZAREK, Kamila PUPPEL, Hubert SZUDROWICZ, Antoni ADAMSKI, Pawe³ BURY-BURZYMSKI, and Teresa OSTASZEWSKA Accepted March 18, 2019 Published online March 29, 2019 Issue online March 29, 2019 Original article LATOSZEK E., KAMASZEWSKI M., MILCZAREK K., PUPPEL K., SZUDROWICZ H., ADAMSKI A., BURY-BURZYMSKI P., OSTASZEWSKA T. 2019. Histochemical characteristics of macrophages of butterfly splitfin Ameca splendens. Folia Biologica (Kraków) 67: 53-60. The butterfly splitfin (Ameca splendens) is a fish species that belongs to the Goodeidae family. The biology of this species, which is today at risk of extinction in its natural habitats, has not been fully explored. The objective of the present study was to characterize melanomacrophages (MMs) and the melanomacrophage centers (MMCs) that they form, associated with the immunological system of butterfly splitfin. Butterfly splitfin is a potential new model species with a placenta for scientific research. In addition, knowledge about the location and characteristics of MMCs will allow the effective development of a conservation strategy for this species and monitoring of the natural environment. The results of histological analyses show that the immune system of fish aged 1 dph was completely developed. Single MMs were observed in hepatic sinusoids and in head kidney and their agglomerations were noticed in the exocrine pancreas and in the spleen. Hemosiderin was detected in single MMs in the head kidney of fish aged 1 dph, and in the spleen, exocrine pancreas and liver of older fish. -

Wild About Learning
WILD ABOUT LEARNING An Interdisciplinary Unit Fostering Discovery Learning Written on a 4th grade reading level, Wild Discoveries: Wacky New Animals, is perfect for every kid who loves wacky animals! With engaging full-color photos throughout, the book draws readers right into the animal action! Wild Discoveries features newly discovered species from around the world--such as the Shocking Pink Dragon and the Green Bomber. These wacky species are organized by region with fun facts about each one's amazing abilities and traits. The book concludes with a special section featuring new species discovered by kids! Heather L. Montgomery writes about science and nature for kids. Her subject matter ranges from snake tongues to snail poop. Heather is an award-winning teacher who uses yuck appeal to engage young minds. During a typical school visit, petrified parts and tree guts inspire reluctant writers and encourage scientific thinking. Heather has a B.S. in Biology and a M.S. in Environmental Education. When she is not writing, you can find her painting her face with mud at the McDowell Environmental Center where she is the Education Coordinator. Heather resides on the Tennessee/Alabama border. Learn more about her ten books at www.HeatherLMontgomery.com. Dear Teachers, Photo by Sonya Sones As I wrote Wild Discoveries: Wacky New Animals, I was astounded by how much I learned. As expected, I learned amazing facts about animals and the process of scientifically describing new species, but my knowledge also grew in subjects such as geography, math and language arts. I have developed this unit to share that learning growth with children. -

THE DIVERSITY OF FISHES Dedications: To our parents, for their encouragement of our nascent interest in things biological; To our wives – Judy, Sara, Janice, and RuthEllen – for their patience and understanding during the production of this volume; And to students and lovers of fishes for their efforts toward preserving biodiversity for future generations. Front cover photo: A Leafy Sea Dragon, Phycodurus eques, South Australia. Well camouflaged in their natural, heavily vegetated habitat, Leafy Sea Dragons are closely related to seahorses (Gasterosteiformes: Syngnathidae). “Leafies” are protected by Australian and international law because of their limited distribution, rarity, and popularity in the aquarium trade. Legal collection is highly regulated, limited to one “pregnant” male per year. See Chapters 15, 21, and 26. Photo by D. Hall, www.seaphotos.com. Back cover photos (from top to bottom): A school of Blackfin Barracuda, Sphyraena qenie (Perciformes, Sphyraenidae). Most of the 21 species of barracuda occur in schools, highlighting the observation that predatory as well as prey fishes form aggregations (Chapters 19, 20, 22). Blackfins grow to about 1 m length, display the silvery coloration typical of water column dwellers, and are frequently encountered by divers around Indo-Pacific reefs. Barracudas are fast-start predators (Chapter 8), and the pan-tropical Great Barracuda, Sphyraena barracuda, frequently causes ciguatera fish poisoning among humans (Chapter 25). Longhorn Cowfish, Lactoria cornuta (Tetraodontiformes: Ostraciidae), Papua New Guinea. Slow moving and seemingly awkwardly shaped, the pattern of flattened, curved, and angular trunk areas made possible by the rigid dermal covering provides remarkable lift and stability (Chapter 8).

There are indications that the strong seasonal presence (late spring to early fall) of sand tigers in this area is a relatively new phenomenon as local fishermen claim that they had never seen this species in large numbers until recently. We utilized passive acoustic telemetry to monitor seasonal residency, habitat use, site fidelity, and fine scale movements of 35 sand tigers (79 – 120 cm fork length; age 0 - 1) in PKD Bay. Sharks were tracked within PKD Bay for periods of 5 – 88 days during September – October, 2008 and June – October, 2009. All movement data are currently being analyzed to quantify spatial and temporal habitat use, however, preliminary analyses suggest that sharks display a high degree of site fidelity to several areas of PKD Bay. Outside PKD Bay, we documented broader regional movements throughout New England. Collectively, these data demonstrate the that both PKD Bay and New England coastal waters serve as nursery and essential fish habitat (EFH) for neonatal and juvenile sand tiger sharks.
