Abstract

The purpose of this study was to identify the natural habitat of Bulbophyllum inconspicuum Maxim. in Hongdo, Jeonnam Province, South Korea. A field investigation was conducted between May 2019 and May 2021. The growth of B. inconspicuum species was confirmed in three known regions based on National Survey on the Distribution of Endangered Species. Additionally, in the area investigated, 37 new regions harboring B. inconspicuum were detected. The newly observed B. inconspicuum grew naturally on Quercus mongolica, Rhaphiolepis indica var. umbellata, Carpinus turczaninowii, and rocks. Most of them were found on southeast and southwest slopes with altitude above 250 m. As few as 10 up to hundreds of B. inconspicuum were found in clusters. Close to their habitat, Calanthe sieboldii Decne. ex Regel, C. aristulifera Rchb. f. and C. × kibanakirishima Maek. were also found. As Hongdo is an island, multiple endangered species were found together. Thus, once the habitat of a certain plant is discovered, it is very likely that illegal collection of several other species will also occur. Proactive internal and external measures are needed to preserve these species.

Abstract

Two unrecorded fungi, Diaporthe perseae and Fusarium falciforme, were isolated from soil sampled from Dokdo in Korea. There have been many reports of Diaporthe sp. and Fusarium sp. in mainland Korea but none of them have reported in Dokdo so far. We used the morphological features and two molecular markers including the internal transcribed spacer and translation elongation factor 1-α region to compare and analyze these species with the closely related taxa. As a result, we confirmed that these fungi were unrecorded soil fungi in Korea. Then, the cultural and morphological characteristics such as the conidia of these two fungal species could be clarified. These results are expected to help us to understand the distribution of fungi in Dokdo and manage the Dokdo Island Natural Reserve.

Abstract

Understanding temporal variations in wildlife populations is a prerequisite for conservation planning of wide-ranging species such as tigers (Panthera tigris). We determined the temporal variation in abundance, population growth, and sex ratios at different age and sex stages for a tiger population in Ranthambhore Tiger Reserve, India from November 2007 to February 2011 using motion-sensing cameras. We identified 19 male and 21 female tigers from stripe patterns during 16,110 trap nights within an area covering 233 km2. The annual abundance of the population varied from 34.9 (mean)±3.8 (SE) to 23.9±1.5, with a declining trend in the mean annual change of abundance (−12%). The density of adult females remained stable across the study duration, but the densities of adult males and non- breeding tigers fluctuated. The sex ratio was female-biased (0.58 males/female) for breeding tigers and male-biased (1.74 males/female) for non-breeding tigers. Our results reinforce the importance of long-term studies for monitoring the naturally occurring processes in populations to develop population indicators and identify reliable baseline information for conservation and management planning of populations.
