Summary: The study described a new myxosporean species infecting farmed Astyanax lacustris fish in Sao Paulo, Brazil, causing pathological changes in the gills. SSU rDNA sequencing revealed the unique genetic sequence of this new species compared to known myxosporean sequences. The new species showed phylogenetic affinity with other South American myxosporeans and demonstrated considerable pathogenic potential.

Summary: During a study on wood-inhabiting fungi in the USA, four unknown specimens were identified as two new species of Fuscoporia - F. hawaiiana and F. minutissima, based on morphological and molecular genetic analyses. F. hawaiiana is characterized by pileate basidiocarps, absence of cystidioles, hooked hymenial setae, and ellipsoid to subglobose basidiospores. F. minutissima is distinguished by small pores and basidiospores. The taxonomic status of these two species is briefly discussed and a key to North American Fuscoporia species is provided.

Summary: A new species of parasitic myxosporean, Henneguya albomaculata n. sp., was discovered in the submucosal tissue of the intestine and pyloric ceca of red drum from the Gulf of Mexico. This species is distinguished from others by its myxospore dimensions, polar tubule coil count, the presence of an iodinophilic vacuole, and SSU rDNA sequence. Phylogenetic analysis revealed a close relationship between H. albomaculata and Henneguya cynosioni, forming a clade with 11 other Henneguya species and 1 Myxobolus species that infect marine or estuarine fishes. This is the second Henneguya species reported in red drum.

Summary: This research describes the histological alterations caused by Henneguya species in African sharptooth catfish, as well as molecular identification and phylogenetic analysis. The study found that 27.5% of the fish were infested by Henneguya species, with a higher prevalence in the gills. The parasitism of the gill and dendritic tissues resulted in histopathological characteristics.

Summary: Two new species from Grande Terre Island, New Caledonia - Fasciamirus petersorum and Simulacala rara - are described based on larval morphology and molecular data. Fasciamirus petersorum is distributed in the southern part of the island and characterized by reduced labial palps and divided abdominal gills. Simulacala rara is known from a single locality in the northern part of the island and characterized by elongated abdominal gills. Both species were found only in areas with ultramafic bedrock.

Summary: This study investigates the development and pathological contributions of Henneguya ictaluri and other myxozoans in proliferative gill disease (PGD) in Channel Catfish and hybrid catfish. The researchers developed species-specific in situ hybridization assays to validate the presence of different myxozoan species in affected gill tissues. They found that while H. ictaluri is the primary cause of PGD, other myxozoan species were also present, potentially contributing to disease pathology. Additionally, the study confirmed impaired or delayed sporogenesis of H. ictaluri in hybrid catfish.

Summary: This study discovered male polymorphism in stalk-eyed fruit flies, presenting four morphotypes in Pe. fukienensis, three in Pe. ichneumoneus and Ps. angustifasciatus. These morphotypes differ in eyestalk length, wing pattern, and the presence of projections or spikes at the ends of the compound eye. Based on new molecular evidence, the study also proposed phylogenetic and phylogeographic implications for the group. Additionally, courtship and mating behaviors between previously recognized different species were observed.

Summary: This study found the likely occurrence of Henneguya infection in the digestive system of the African sharptooth catfish, Clarias gariepinus. Two species of Henneguya were identified in the stomach and intestine of the catfish based on spore morphology and tissue specificity. Several histopathological changes were observed in the intestine, potentially affecting fish performance and survival.

Summary: A new myxosporean species, Myxobolus zhaltsanovae n. sp., was discovered in the gills of gibel carp Carassius gibelio from Lake Baikal, Russia. The species was characterized morphologically and genetically, with plasmodia measuring 500-1000 μm in length and 25-100 μm in width. The myxospore had circular to oval shape, with dimensions of 13.23 +/- 0.09 (11.3-14.8) μm in length, 10.19 +/- 0.07 (9.1-11.4) μm in width, and 6.49 +/- 0.12 (5.4-7.2) μm in thickness. Phylogenetic analysis revealed M. zhaltsanovae n. sp. to be closely related to M. musseliusae, M. tsangwuensis, and M. basilamellaris, which infect common carp Cyprinus carpio.

Summary: Habitat quality plays a crucial role in regulating population size and fitness, which are difficult and costly to assess. The study evaluates habitat quality for New England and eastern cottontails, finding that habitat selection may not always reflect habitat quality, leading to complex trade-offs between density, survival, and other factors. Further research and direct assessment of factors impacting habitat quality are crucial in management plans for the recovery of imperiled species like the New England cottontail.

Summary: A new myxozoan species, Ceratomyxa binhthuanensis n. sp., was discovered in the gall bladder of blacktip grouper in the East Sea of Vietnam. The species is characterized by elongate and slightly crescent-shaped mature myxospores, two smooth equal shell valves, and spherical polar capsules of equal size. Molecular analysis reveals that Ceratomyxa binhthuanensis n. sp. is distinct from other Ceratomyxa spp. available in GenBank. Phylogenetic analysis shows a close relationship between C. binhthuanensis n. sp. and three other Ceratomyxa species that infect fish hosts of the genus Epinephelus.

Summary: Nematocysts play a crucial role in the adaptive success of cnidarians, showing extensive species-specific adaptations and rapid evolution. There is evidence of a significant macroevolutionary lag between nematocyst evolution and cnidarian diversification, highlighting the potential driving force of nematocysts in evolution. Quantitative analysis reveals an abundance of adaptive changes in nematocyst proteins, indicating their importance in cnidarian adaptation.

Summary: The populations of lesser and greater snow geese have significantly increased in the past 50 years. Measures were taken in Canada and the United States in 1998 and 1999, respectively, to stabilize the populations and increase the harvest. Differentiating between the subspecies using morphology can be helpful for managing the harvest. Analysis of the spring harvest data in New York state shows that 80% of the harvest consists of greater snow geese, indicating a shift in their migration patterns since the 1990s.
