Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Duckweeds under salt stress: a meta‐analysis of growth inhibition in relation to morphological and physiological traits and a systematic review of molecular responses

New Phytologist, EarlyView.
Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.

Climate Change and Temperature‐Based Stratification in Shallow Lakes and Ponds in Warm Climate Regions

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Thermal stratification in shallow lakes (< 5 m, > 5 ha) and ponds (< 5 m, < 5 ha) in warm climate regions is understudied. A comprehensive review was done to identify the effects of climate change on stratification patterns, their effects on the ecology of shallow waterbodies and implications for management of shallow waterbodies.
