Elevational patterns of orchid diversity in mid-subtropical mountain forests of eastern China by Qinghua Zhan, Haihong Liao, Yuelong Liang, Zhong Zhang, Xingui Le, Yu Xiong, Lin Cheng, Wenqi Ding, Jian Lu, Yadong Zhou, Boyun Yang

“…In this study, we conducted an investigation of orchids across more than 1900 5 m × 5 m plots in six mountains located in central China, spanning an elevational range from 166 m to 1930 m, and then converted these survey data into the distribution data in 100 m elevational bands to study the trend of species richness (S), Shannon-Wiener index (H'), Simpson index (D), and Pielou evenness (e) of orchids variation along the elevational gradients. …”

Potentiel floristique du sous-bois des agrosystèmes à Elaeis guineensis Jacq. en zone équatoriale (Ngwei, Cameroun) by Baruch Batamack Nkoué, Damien Marie Essono, Thomas Guillaume, Émile Narcisse Njila Nana, Hyacinthe Angoni, Jean Louis Fobane, Armand William Mala

“…Forest ecosystems' conversion into elaeicultural agrosystems shows that the specific richness of palm groves is very variable and that a high number of species can be reached already in young plantations, thus competing with older plantations. The superiority of Simpson's diversity index (0.99) and of αFicher's indicator (79.86) in palm groves compared to forests (0.96 and 23.64 respectively) shows that the palm grove's understory is highly diversified. …”

Circular light orbits of a general, static, and spherical symmetrical wormhole with $$Z_2$$ Z 2 symmetry by Naoki Tsukamoto

“…In this study, we categorize the numbers of the circular light orbits of the $$Z_2$$ Z 2 -symmetrical wormhole and their stability from the derivatives of an effective potential at the throat and we investigate the circular light orbits around a Simpson–Visser black-bounce spacetime, a Damour–Solodukhin wormhole spacetime, a Reissner–Nordström black-hole-like wormhole spacetime or a charged Damour–Solodukhin wormhole spacetime as examples. …”
