Abstract Temporary pools are freshwater bodies of significant interest due to their high species diversity, and the colonization and extinction processes observed at temporal scales. The aim of the present study was to perform a short-term ecological comparison in a group of shallow temporary pools in northern Chilean Patagonia in two periods, August and September 2018. The results revealed marked differences in terms of species richness in the study pools at different conductivities and chlorophyll a concentrations. The dominant species was the calanoid copepod Boeckella gracilis Daday, 1902, while the presence of the rare Anostracan Branchinecta rocaensis Cohen, 1982 was reported in conditions of low chlorophyll a and low conductivity. The community was studied using co-occurrence null models that revealed the absence of structured patterns in species associations, and the presence of niche overlap, with many repeated species that have a similar ecological niche. The present results are identical with observations from temporary pools in southern Chilean Patagonia.

The Galapagos slipper lobster (Syllarides astori Holthuis, 1960) is a species extensively distributed on rocky and coral reefs, sand, and mud in the Eastern Tropical Pacific Ocean, within the Gulf of California, Galapagos Archipelago, mainland Ecuador, and Isla de Cocos. Its presence has been reported in the southern region of the Baja California peninsula (Los Cabos). Here we report the presence of S. astori in the Baja California peninsula from Natividad Island, Guadalupe Island, and Socorro Island, Revillagigedo Archipelago. The Guadalupe Island record extends the distribution of this species 1,055 km north of its known limit. We developed a potential distribution model, and the results revealed a high probability of occurrence in different regions of the Eastern Tropical Pacific, such as the Baja California coast, Gulf of California, Colombia, and Ecuador.
