Cover Image Telipogon peruvianus is a highly restricted Neotropical orchid species, endemic to the southern Peruvian Andes. It is only known from two localities, which are affected by anthropogenic disturbance. The present study investigated whether the restricted distribution of T. peruvianus has led to low genetic diversity and inbreeding, thus threatening its survival. https://doi.org/10.1111/1442-1984.12291

Beautiful underwater view of an edible brown alga, Sargassum fusiforme (Fucales, Phaeophyceae) at the rocky shore in Sakurajima, Kagoshima, Japan (Photo by Ryuta Terada). Characteristic responses of the PSII photochemical efficiency on desiccation and salinity gradients in S. fusiforme are reported by Yonemori et al. in this issue.
Scanning electron micrographs of two members of the marine diatom genus Nagumoea, N. africana (the left four photos) and N. serrata (the right two). This genus is characterized as unique by the ladder-like structure of its internal valve as shown in the image. Morphology and molecular phylogeny of this genus are reported by Sugawara et al. in this issue.
This study presents a novel intraoperative in vivo imaging approach which harnessed Cerenkov luminescence (CL) to detect primary and metastatic colorectal cancer (CRC) using clinically approved radiopharmaceuticals. In the mice and swine experiments, the proposed approach effectively improved the effect of CRC surgery. The approach is believed to be promising for utilizing CL in open surgery.

A comparative analysis of intrinsic skin aging between Caucasian and Asian subjects by slide‐free in vivo harmonic generation microscopy is reported. The cellular and nuclear areas of basal cells in Caucasians and Asians are found to increase at the same rate, ideal for scoring age. On the other hand, the viable epidermis thickness, the dermal papilla volume and height in Caucasians are found to decrease faster than those in Asians. Further details can be found in the article by Kuan‐Hung Lin, Yi‐Hua Liao, Ming‐Liang Wei, and Chi‐Kuang Sun ( e201960063 ).
