Semi-aquatic

Marine mammals have adapted to an aquatic or semi-aquatic lifestyle with such features as reduced or eliminated limb structures, a blubber layer for thermoregulatory, nutritional, buoyancy and locomotory roles, and reproductive strategies conducive to fitness in a given biogeographic zone (habitat). The environmental challenges faced by newborn marine mammals at birth may explain there largely precocious nature and the apparent maturity of the immune system of newborn marine mammals [1],...

Otters are small to medium-sized mammals with a long body, flattened head, broad muzzle, and long stiff whiskers. Their tail is strong, long, flattened, and somewhat tapered. Otters have short legs and webbed toes they are well adapted to a semi-aquatic existence and are skilled swimmers. The outer fur of otters is short, very... 

Root Histology.—Monocotyledons.— The histology of mono-cotyledonous roots varies, depending upon relations to their surroundings, which may be aquatic, semi-aquatic, mesophytic, or xerophytic. In this connection we will discuss only the type of greatest pharmacognic importance, f.e.,-the mesophytic type as seen in its most typical form in the transverse section of Honduras Sarsaparilla root. 

I have a very large and healthy specimen of A. calamus now growing in hydroponic culture being aquatic or semi-aquatic, it thrives in this moist environment. I ve never ingested any, since I m not at all convinced that it is hallucinogenic, and am not willing to sacrifice my beautiful plant to find out.

It is our general prejudice that the proportion of chemical sensing within the total sensory capabilities is greater in aquatic and semi-aquatic animals than in more terrestrial forms where vision in particular dominates. Thus it was somewhat of a surprise to us when we were unable to locate many recent publications on orientation and homing in the more aquatic amphibians. While our finding of an apparent lack of research on amphibians may be partially due to our own admitted historical bias towards the reptilian literature, we also believe that there indeed has been relatively less work on amphibians. It appears that since the important pioneering studies of Twitty (summarized in Twitty, 1966), very few scientists have had an interest in this area. 

Methanotrophic bacteria are widespread in nature. They inhabit all upland, semi-aquatic and aquatic environments of different climate zones. Methanotrophic bacteria or the effects of their activities were observed in arable soils (Hiitsch, 1998, Arif et al. 1996, Knief et al. 2005), forest soils (Reay et al. 2001, Wang Ineson, 2003, Knief et al. 2005), meadow soils (Bender Conrad, 1993, Horz et al. 2002, Abell et al. 2009), peat soils (Sundh et al. 1995 Mac Donald et al. 1996), rice paddy soils (Kolb et al. 2003, Macalady et al. 2002) in lake sediments (Auman et al. 2000, Costello et al. 2002) and sea sediments (Yan et al. 2006). Moreover, methanotrophs frequently occur in landfill cover soils (Wise et al. 1999, Kallistova et al. 2007, Cebron et al. 2007). They were also isolated from geothermal waters, hot springs (Tsubota et al. 2005, Dunfield et al. 2007), and soda lakes (Khmelenina et al. 1997). 

Bacillariophyceae, or diatoms, are extremely widespread in the marine environment, and constitute the greatest proportion of the phytoplankton (95-98%). Thus, they are responsible for most of the oceanic photosynthesis, although benthic species also exist. The diatoms are also found in great quantities in freshwater and other aquatic and semi-aquatic habitats. An estimate of the number of species is about 100000, and the estimated proportion of marine species varies from 30% to 50%. Hence, there would be between 30 000 and 50 000 species of marine diatoms (Armbrust, 2009).
