In this study we explore the possible role of phenotypic plasticity in the process of adaptation and evolutionary change in the African cichlid Pseudocrenilabrus multicolor victoriae. Parental fish were collected from a hypoxic swamp, a lake ecotone, and a river in Uganda. Broods (F1) were split and grown under hypoxia or normoxia. We measured morphological parameters of the gill apparatus, str...

In the mid-1990s Trinidadians witnessed a hotly contested resource conflict in the Nariva Swamp, a wetland located on the east coast of the island. This conflict resulted in a stricter regime of environmental protection and greater influence of conservation-oriented government agencies, and demonstrates the role of representations in influencing spatial practice. Drawing on the critical landsca...

In Southeast Asia, swamp eels (Synbranchidae: Monopterus spp.) are a common source of human gnathostomiasis, a foodborne zoonosis caused by advanced third-stage larvae (AL3) of Gnathostoma spp. nematodes. Live Asian swamp eels are imported to US ethnic food markets, and wild populations exist in several states. To determine whether these eels are infected, we examined 47 eels from markets and 6...

Structure and composition of coastal forested wetlands are mainly controlled by local topography and soil salinity. Hydrology plays a major role in relation with tides, seaward, and freshwater inputs, landward. We report here the results of a two-year study undertaken in a coastal plain of the Guadeloupe archipelago (FWI). As elsewhere in the Caribbean islands, the study area is characterized b...

There is a hypothesis that fragments of a body from outer space fell to Earth as a result of the Tunguska event. During decades of investigations at the site of the disaster, stone or iron pieces from a cosmic body were not found. In spite of this, the number of adherents of this hypothesis is growing. For one thing, it was determined that the formation of swamp craters at the epicentre of the ...

The water buffalo (Bubalus bubalis) is considered an efficient converter of poor quality forages into high quality milk and meat. This species is ubiquitous, with prevalence though in Asian and Mediterranean countries. From a genetic standpoint, the species is characterized by two main subspecies: river and swamp type. The former to be found predominantly in Mediterranean countries, whereas the...
