A. blitum is a monoecious annual weed with a near global distribution. Principal threats to amphibian survival (uncontrolled urban extension, alteration and destruction of habitat, pollution, road kills, and introduction of several predator species) vary slightly from north to south. Despite an increasing number of man-made habitats (irrigation canals), southern localities continue to suffer from lack of suitable habitat due to natural and human causes.

In the 1960s, at the time that cultivation of the adjacent peatland began, Majen Chitane underwent strong ecological changes as the initial oligotrophic plant, diatom and zooplankton communities were replaced by eutrophication-tolerant ones. Yıldırım, a species recently described from SE-Turkey, is recorded for the first time to the flora of Iraq based on samples collected from Amadya and Duhok areas (N-Iraq). The most effective essential oil was obtained from the leaves of C. grandiflorum, that inhibited the relative growth rate (−0.03 mg/mg/d), efficiency of conversion of ingested food (−50.69%), relative consumption rate, caused an antifeeding effect (66.43%) and a high mortality (80%) of T. confusum larvae.

The genetic differentiation among populations and varieties was assessed using flower traits (corolla length, pollen grain size, fertility and viability, style and stamen length), essential oil compounds, allozymes and RAPDs. In addition, all isolated flavones were evaluated for their antioxidant, anti-inflammatory, anti-superoxide dismutase, anti-xanthine oxidase and cytotoxic activities. Further investigations are needed for improving the conservation of the rare plants of Mediterranean temporary pools as well as contributing to a better knowledge of the mechanisms controlling their distribution and their present-day status. Plant nomenclature follows Le Floc'h et al.
