Regeneration of the Caudal Fin of Atractosteus tropicus The Tropical Gar
Abstract Bacground: The tropical gar (Atractosteus tropicus) belongs to the lepisosteidae family, with habitats from southeast Mexico to the south of Costa Rica. Due to its phylogenetic position, slow evolution speed (base substitution), dense genetic map, gene similarity with human beings, and ease of cultivation in laboratories, this ...

Revista de Biología Tropical, 2016 Tropical gar A. tropicus plays an important ecological role, as a regulator of other fish stocks, in the water bodies of Mexico but their wild populations are being reduced. One conservation alternative is breeding which requires the study of germ and somatic structures of testis to characterize the reproductive cycle, basic knowledge required to ...

Wood inhabiting macro-fungi in tropical landscape and home-gar den trees: Their diversity and roles
Proceedings of International Forestry and Environment Symposium, 2012 Wood is a biodegradable natural resource, and is often affected by various wood-inhabiting fungi. Hence, this study was carried out to investigate the diversity and impact of macro-fungi on landscapes and home-gardens in semi-urbanized areas in Colombo suburbs.

Latin American Journal of Aquatic ResearchTropical gar (Atractosteus tropicus) is an ecologically, culturally, economically, and scientifically important species. Therefore, it is essential to know the available resources to design feeds for the culture of this species. This study evaluated the in vitro digestibility of meals and oils commonly used in aquaculture, using crude extract of the ...

Latin American Journal of Aquatic ResearchThe tropical gar (Atractosteus tropicus), a freshwater species mostly found in swamps, has been used for human consumption for several generations. In this study, the expression of interferon-gamma (ifn-γ) and domain nucleotide-binding oligomerization (nod1) involved in the immune system was evaluated in different tissues such as the brain, heart ...

Developmental DynamicsAbstractBackgroundDentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Revista de biologia tropical, 2010 The karyotype of the tropical gar Atractosteus tropicus is described from conventional Giemsa-staining of 295 mitotic chromosome slides from 120 larvae and 15 adults (five females and ten males) from Tabasco, southern of Mexico. The diploid number 2n = 56 chromosomes was calculated (73 spreads from 206 larval and 208 adult metaphases).
