Novel secondary metabolites from a Madagascar collection of Lyngbya majuscula

Creator:: Nannini, Christopher J.
Abstract:: Marine organisms produce a variety of secondary metabolites for defense, communication, and reproduction. While these uses are essential for the organisms' survival, marine natural products have demonstrated their value to human society as well. Asian countries used algae for centuries to treat or prevent illnesses as wide-ranging as cough, gout,...

Creator:: Poinar, George O., Jr.
Abstract:: Four new species of fossil mermithids (Nematoda: Mermithidae) are described from amber: Heydenius arachnius n. sp. from a spider (Arachnida: Araneae) in Dominican amber, Heydenius phasmatophilus n. sp., from a walking stick (Phasmatodea: Phasmatidae) in Baltic amber, Heydenius podenasae n. sp. from a moth (Lepidoptera) in Baltic amber and Heydenius...

Vetufebrus ovatus n. gen., n. sp (Haemospororida: Plasmodiidae) vectored by a streblid bat fly (Diptera: Streblidae) in Dominican amber

Creator:: Poinar, George O., Jr.
Abstract:: Background: Both sexes of bat flies in the families Nycteribiidae and Streblidae (Diptera: Hippoboscoidea) reside in the hair or on the wing membranes of bats and feed on blood. Members of the Nycteribiidae transmit bat malaria globally however extant streblids have never been implemented as vectors of bat malaria. The...

Halophilanema prolata n. gen., n. sp. (Nematoda: Allantonematidae), a parasite of the intertidal bug, Saldula laticollis (Reuter)(Hemiptera: Saldidae) on the Oregon coast

Creator:: Poinar, George O., Jr.
Abstract:: Background: It is rare to find terrestrial nematode lineages parasitizing arthropods inhabiting the intertidal or littoral zone of the oceans. During an ecological study along the Oregon dunes, an allantonematid nematode (Tylenchomorpha: Allantonematidae) was discovered parasitizing the intertidal shore bug, Saldula laticollis (Reuter) (Hemiptera: Saldidae). This shore bug is adapted...

Paleorhodococcus dominicanus gen. nov., sp. nov., a fossil Actinobacteria in a fecal droplet of Triatoma dominicana (Hemiptera: Reduviidae: Triatominae) in Dominican amber

Creator:: Poinar, George, Jr.
Abstract:: Paleorhodococcus dominicanus n. gen., n sp. (Actinobacteria) is described from a fecal droplet of Triatoma dominicana (Hemiptera: Reduviidae: Triatominae) in Dominican amber. The fossil can be distinguished from most extant species of the closely related extant genus Rhodococcus Zopf, 1891 by its spherical cocci forming substrate filaments with elementary branching,...

Silica bodies in the Early Cretaceous Programinis laminatus (Angiospermae: Poales)

Creator:: Poinar, George, Jr.
Abstract:: Silica bodies in short cell epidermal leaf cells of the Early Cretaceous Programinis laminatus (Poales) in Burmese amber are characterized. The great majority are rondels and elongated quadrates aligned horizontally in relation to the leaf axis. Rondel types include circular, elliptical, oblong, long and short forms. Quadrate types include short...

A New Genus of Fleas with Associated Microorganisms in Dominican Amber

Creator:: Poinar, George, Jr.
Abstract:: A flea preserved in Dominican amber is described as Atopopsyllus cionus, n. gen., n. sp., (Atopopsyllini n. tribe, Spilopsyllinae, Pulicidae). The male specimen has two unique characters that have not been noted in previous extant or extinct fleas, thus warranting its tribal status. These characters are 5-segmented maxillary palps and...

Bird’s nest fungi (Nidulariales: Nidulariaceae) in Baltic and Dominican amber

Creator:: Poinar, George, Jr.
Abstract:: Nitula baltica sp. nov. and Cyathus dominicanus sp. nov. are described from Cenozoic Baltic and Dominican amber. These are the first fossil members of the Family Nidulariaceae and show that the basic characteristics of this group were already established some 40-50 million years ago.
