Cattleya warscewiczii 40; the haploid chromosome number as "n" = 20. "C. warscewiczii" hybridizes naturally with "C. aurea / dowiana", producing "C. x hardyana". "C. warscewiczii" has also been used extensively in Cattleya hybridization, to produce large-flowered hybrid Cattleyas. Cattleya warscewiczii Cattleya warscewiczii (The "Warscewicz's Cattley's orchid"), a labiate "Cattleya", is a species of orchid. It was first collected by Józef Warszewicz in Colombia in 1848-49 and formally described by Heinrich Gustav Reichenbach in 1855. "C. warscewiczii" exhibits a typical Cattleya sympodial habit. Pseudobulbs are 8-16" (20-40 cm) long, unifoliate, cylindrical or cigar-shaped, grooved. Flowers are 7-11" (17.5-27.5 cm) across, largest in
Tilapia as exotic species and utilize the Salton Sea as an important destination for resting and feeding along the Pacific flyway. High salinity concentrations, algal blooms, agricultural runoff, hypoxia, wind events and temperature variability all contribute to fish die-offs in the Salton Sea. The high concentrations of tilapia in the Salton Sea (relative to other fish species) signify that tilapia often constitute the largest percentage of dead fishes during periods of excessive environmental stress. During fish kills, tilapia often wash ashore en masse. Tilapia as exotic species Throughout much of the tropics, tilapiine cichlids native to Africa and the Levant have been widely introduced
