DOI: 10.1002/ece3.9635
Abstract: Abstract Giant clams are ecologically important, benefitting species of all trophic levels. But numerous populations have declined drastically in numbers due to past intensive exploitation that led to their listing in both CITES Appendix II… read more here.

DOI: 10.1007/s10201-021-00653-3
Abstract: Vertical circulation reaches the bottom of the deepest (> 90 m) part of the northern basin of Lake Biwa, a warm monomictic lake, during winter (January to March) every year. In winter 2019, we found non-circulated water… read more here.

DOI: 10.1051/0004-6361/201629897
Abstract: Context. The so-called H α third emission occurs around pulsation phase ϕ = 0.30. It has been observed for the first time in 2011 in some RR Lyrae stars. The emission intensity is very weak,… read more here.
