Abstract

Goniodes dissimilis (Denny, 1842) is one of the chewing lice (Ischnocera: Phthiraptera) that commonly infests native chickens (Gallus gallus domesticus). The aims of this study were to describe the morphological and ultrastructural characteristics of G. dissimilis using scanning electron microscopy (SEM). The sampling of Goniodes dissimilis was conducted in Seruawan, Hatusua, and Kamarian villages on Seram Island. SEM preparation was carried out through 2.5% glutaraldehyde fixation, 0.25 M phosphate buffer post-fixation, multistage dehydration, critical-point drying, mounting on stubs, and gold coating before being observed at various magnifications. SEM results showed that G. dissimilis from Seram Island has ultrastructural characteristics, such as the head is circumfasciate with a rounded anterior margin, a complete band on the marginal carina, a pulvinus surrounding the ventral carina, and no hyaline margin. The eyes appear reduced with long ocular setae, while the temporal region has five marginal setae, with setae numbered 2 and 3 presents. The antennae are sexually dimorphic, consisting of a scape, pedicle, and three flagellomeres. In this study, we collected only females of G. dissimilis, and the first flagellomer shows no radial grooves in the sensilla placodea. The thorax shows a pteronotum with several long spines, while the abdomen shows medially separated tergums II–VIII, spiracles on tergums III and VIII, and a thin, membranous sternal plate. The SEM results also show that the female G. dissimilis has terminalia displaying a dorsal plate connected with tergopleurites and a vulva lined with fine setae. This finding represents the first ultrastructural record of the G. dissimilis population on Seram Island, thereby enriching the morphological diversity and distribution data of chewing lice in the Maluku region.

Abstract

Ferns (Pteridophyta) are vascular plants possessing true roots, stems, and leaves, and they reproduce by spores, whose morphological characteristics constitute critical diagnostic features for taxonomic identification. The Treehouse Ecotourism Area of Waai Village harbors significant fern diversity that is increasingly threatened, rendering spore characterization an essential approach for conservation, species identification, and the advancement of scientific research as well as ecotourism development. The aim of this study was to examine the characteristics of fern spores found in the Tree houses ecotourism area, Waai Village, Central Maluku, as a contribution to conservation efforts, ecotourism education, and the enrichment of fern micromorphological references in Maluku. The research was conducted using an exploratory survey method along an approximately 20-km trail from the entrance gate to the tourism site. Fern leaf samples were collected to observe soral and spore structures using whole-mount preparations, followed by acetolysis, washing, staining, and mounting procedures. Characterization was carried out microscopically, focusing on sorus form, position, and color, as well as spore morphology, including grain shape and aperture type. The results revealed nine spore-bearing fern species: Pteris vittata, Cyclosorus interruptus, Pteridium aquilinum, Blechnopsis orientalis, Sticherus underwoodianus, Nephrolepis exaltata, Lygodium microphyllum, Lygodium flexuosum, and Pityrogramma calomelanos. The observed soral characters varied from linear, laminar, and granular to powdery forms, and were located either abaxially or adaxially. Spore shapes included oval, round, and triangular forms, with both monolete and trilete laesura types. This variation in soral and spore characteristics provides a basis for the taxonomic identification of ferns and supports further studies in biogeography and phylogenetics.
