Identification of acara (Cichlidae: Cichlasoma) established in Florida, USA

Dengue in Florida (USA)

Florida (USA), particularly the southern portion of the State, is in a precarious situation concerning arboviral diseases. The geographic location, climate, lifestyle, and the volume of travel and commerce are all conducive to arbovirus transmission. During the last decades, imported dengue cases have been regularly recorded in Florida, and the recent re-emergence of dengue as a major public he...

Parental behavior and some histological features of scales in Cichlasoma citrinellum (pisces, Cichlidae)

A morphometric analysis of polymorphism in the pharyngeal dentition of Cichlasoma minckleyi (Teleostei: Cichlidae).

Dental polymorphism in teleost fishes often involves production of a robust dentition, or "molarization", in one morph. The lower pharyngeals of a sample of wild-caught individuals of the polymorphic Cuatro Cienegas cichlid, Cichlasoma minckleyi (Kornfield and Taylor) (Proc. Biol. Soc. Wash. 96 (1983) 253), were measured to investigate morphological changes associated with molarization. Princip...

Ecological and evolutionary consequences of the trophic polymorphism in Cichlasoma citrinellum (Pisces: Cichlidae)

Reproductive tactics optimizing the survival of the offspring of Cichlasoma orientale (Perciformes: Cichlidae).

High mortality rates have been observed in Teleost during early developmental stages, as well as great variations in reproductive tactics, which are related to adaptations towards environmental conditions and ecological niches for which different species have a specific response. The objective of this study was to describe reproductive tactics related to the survival of Cichlasoma orientale off...
