Comprehensive genetic analysis reveals the genetic structure and diversity of Calanthe hoshii (Orchidaceae), an endemic species of the Ogasawara Islands: Implications for appropriate conservation of a critically endangered species

Plant Species Biology, Volume 39, Issue 5, Page 297-305, September 2024.
Calanthe hoshii stands out as highly susceptible to extinction. In this research, we conducted a genetic analysis of the wild and ex situ individuals, which revealed extant C. hoshii maintains a remarkably low genetic diversity at both individual and population levels.

The effect of sikkam (Bischofia javanica) leaf extract on blood sugar levels and islet of langerhans in alloxan-induced diabetic rats

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Diabetes Mellitus is a metabolic disease characterized by hyperglycemia, occurring due to abnormal insulin secretion or insulin action. Alloxan induces diabetes by damaging pancreatic cells and initiating hyperglycemia. One of the plants that has the potential to decrease blood sugar is leaves of sikkam (Bischofia javanica ...

Elevational differences in territory defence response in native (endemic and non‐endemic) forest birds on Viti Levu Island, Fiji

New Zealand Journal of Zoology, Volume 51, Issue 2, Page 301-316, June 2024.
ABSTRACT Experimental approaches to measure territory defence can be used to interpret the relative magnitude of intraspecific aggression in different ecological contexts. The aim of this study is to examine the response of Fijian forest bird species to conspecific intruders using playback of previously recorded songs along an elevational gradient.
