Abstract. Andreychev A. 2021. Short Communication: Proportion faunal assemblages of carnivorous mammals in geoecological districts of Mordovia, Russia. Biodiversitas 22: 4625-4632. In the forest-steppe area, carnivorous mammals are represented by species of different faunistic assemblages. This circumstance makes the study region a priority since the species of which faunistic assemblages prevail is of interest. Fifteen carnivorous species have been identified in the territory of Mordovia. Among them, the family Mustelidae predominates in terms of the number of species. The species are found in all geoecological districts, but their distribution is uneven. The most notable species in the region are located in coniferous and broad-leaved forests (40%) and species widely distributed in several natural areas (40%). 13% of the total number of noted species belong to the taiga fauna types. The steppe type of fauna is represented by only 7% of the total number of recorded species. For each geoecological region, the fauna features are given, and a list of rare and exciting species is given. The forest-steppe zone to which Mordovia belongs is compared by the fauna of carnivorous mammals with other regions from three typical faunal assemblages.

Level Information

Genus Oberonia Lindley is one of the species rich genera in the family Orchidaceae.  According to the latest literature found in Sri Lanka, there are 50 endemic species, including nine endemics belonging to the genus Oberonia among 184 species in the family Orchidaceae. On comparing it with global level information, a revision of statistics on regional level seems vital.  This short communication discusses the required revision in regional distribution of the genus Oberonia while documenting the first observation of vegetative propagation of the genus Oberonia from Sri Lanka.

Abstract. MeinataA, Na’iem M, Adriyanti DT, Syahbudin A. 2021. Short communication: Leaf architecture of 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes in Carita, Banten, Indonesia. Biodiversitas 22: 2952-2960. Dipterocarpaceae is a major commercial timber characterized by high unbranched bole, paired stipules, and winged fruit. The identification process in the family becomes problematic, in cases where the generative organ is absent. Therefore, a new approach needs to be established to address any misidentification leading to improper utilization. This study aims to determine the leaf architecture in 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes (KHDTK) Carita, Banten, Indonesia. The ten leaf samples collected were the third and fourth leaves from terminal shoots of a single tree of each species. Subsequently, the data were observed and measured based on the 17 morphological characters. Each character was then scored and analyzed using multivariate analyses cluster to determine the relationship between species. Dipterocarpaceae generally has pinnate leaf category, geniculate petiole, and entire margin. Furthermore, the phenon line in the dendrogram is cut at 0.695 similarity level to establish meaningful interpretation. The 35 species observed were grouped into 4 major clusters. Small leaf group, inconsistent tertiary vein pattern group, symmetrical leaves with cordate base leaf group, and other groups that do not resemble mentioned characters. The key determination comprised 34 couplets with three characters repeated due to limited descriptors.

Biodiversitas 20: 719-724. We studied the activity budget and diet of a group of wild silvery lutungs (Trachypithecus cristatus) in Gunung Padang, West Sumatra, Indonesia, with special attention to age-and sex-related differences. We conducted behavioral observations between July and October 2016, and found that resting constituted the greatest proportion of their daily activities (46%), followed by moving (38%), feeding (12%), and grooming (4%). Resting peaked between 11 am and 1 pm, while moving decreased in this period. The juveniles showed higher percentage of moving and lower percentage of feeding than the adults. The adult males showed higher percentage of grooming than the adult females. Finally, the nursing females showed lower percentage of resting and higher percentage of grooming than single females. During the study, we recorded 14 plant species consumed by the lutungs. Their dietary composition was composed of 63% foliage and 37% fruit. Both the foliage and fruits of Ficus variegata, a plant species belonging to the family Moraceae, was the most consumed. Foliage was frequently consumed by the nursing females and juveniles. The adult males were frequently observed to eat fruit during the study period. No fruit was consumed by the nursing females.

Abstract. Sudarmono. 2018. Short Communication: Pollen diversity in the Bogor Botanic Gardens, Indonesia. Biodiversitas 20: 931-936. Pollen morphology influenced the process of plants evolution. Bogor Botanic Gardens has many living collections in terms of pollen diversity. The purpose of this study was observed at the diversity of pollen morphology at the Bogor Botanic Gardens and its implications for the pollen conservation of plants in the collection. The method used is cleaning the pollen using Glacial Acetic Acid (AAG), then examined using a light microscope in the tissue culture laboratory of Bogor Botanic Gardens. There were 35 specimens that were analyzed and the results were randomly shaped pollen from radial symmetry or bilateral symmetry to its combination with monocolpate, tricolpate, pericolpate and stephanocolpate. While aperture types were the monoporate type with 5 specimens, monocolpate 10 specimens, tricolpate 11 specimens, stephanocolpate 4 specimens, periporate 4 specimens, and syncolpate 1 specimen. Three specimens families Caesalpiniaceae (order Fabales) has the shape of pollen vary, i.e radial symmetry monocolpate and radial symmetry tricolpate. Similarly, two specimens of the family Araliaceae (Apiales) different shapes, namely radial symmetry and bilateral symmetry tricolpate. In Asteraceae and Asclepiadaceae has the same shape, the radial symmetry tricolpate. Overall of 35 specimens then there are 22 specimens of radial symmetry and 13 specimens of bilateral symmetry. For the same family have the same ornamentation, for example in the Lamiaceae, Malvaceae, and Rutaceae. But the uniqueness occurs in the family of Arecaceae or palm family that show the diversity in the shape and size of pollen in each genus. Pollen morphology analysis through a combination of morphological data, palynology, and molecular samples more would be better. Pollen bank as pollen in the living collections of Bogor Botanic Gardens is needed to germplasm conservation of endangered plants in Indonesia.

AbstractLive oribatid mites of the family Malaconothridae were found on Salmo spp. parr caught in the rivers of Northwest Russia. The mites were localised in the gill filaments and enclosed in connective tissue capsules. The encapsulation was accompanied by hyperplasia and displacement of the respiratory epithelium. One mite specimen was an adult female, while all the other specimens were protonymphs. The adult female and one protonymph specimen were identified as Tyrphonothrus sp. Other protonymphs could be identified only at the family level. The obtained partial 18S rDNA sequence of one protonymph was 100% identical to that of Tyrphonothrus maior (NCBI accession No. KY922215). This is the first report of living malaconothrid mites encapsulated in fish gills, and the phenomenon may assume parasitic behaviour. However, the nature of the relationship between the mites and the fish requires further investigations.

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.
