comments that the low number of eggs found in the pouch, in combination with the considerable size of the eggs themselves, may be also considered characteristics connected with the subterranean habitat. Additionally, fewer and larger eggs and offspring have also been reported in other subterranean amphipods.

females appear to allocate excess energy to more voluminous eggs rather than to a greater number of eggs. The volume of an egg often correlates positively with its nutritional value, which lengthens the development within the egg. In turn, this results in larger juveniles, with greater fitness and probably greater ability to cope with the challenges of the subterranean environment.

, are among the most vulnerable areas in the country with respect to global climate change, as they are highly dependent on the water from the Andes. In these provinces, the last decades have witnessed a reduction of the flow of rivers and the consequent decrease in the fluvial contribution to aquifers. This has had negative effects on the surface water supply during the summer, when there is greater demand for water as a resource for various uses (mining, agriculture, domestic usage, etc.). This situation generates greater demand for groundwater extraction, in turn negatively affecting its stygofauna.

At the local scale, and specifically in 2015 after the sampling we carried out along the Calingasta River, we recorded several transformations of the riparian landscape. Funded by both governmental and private sources, numerous hydraulic constructions (

) were carried out with the goal of widening and profiling the channel that redirects part of the Calingasta River course, approximately from the water intake at Villa Calingasta to its mouth into the Los Patos River; including the construction of gabion mattresses on both banks of the riverbed. These hydraulic works were partly a response to the remediation for mine tailings dumps. Removal of the bed and banks of a reach of the Calingasta River were observed in the proximity of the sampling site for crustaceans described here.

These landscape modifications and the consequent habitat fragmentation, combined with climatic changes (low rainfall), are key factors in the loss of groundwater species.</paragraph>

Thus, it becomes strongly necessary to assess the changes in hyporheic biodiversity that took place after the infrastructure works on the Calingasta River should be evaluated after the infrastructure works developed in the River. Among the hyporheic taxa that may have been most affected by these environmental changes are endemic species such as
