In a river of northeastern Brazil, an “armored” creature with “large” eyes paused to rest against a rock. The maze-like ...

Well-designed marine parks can conserve marine life and their habitats, allow fish populations to recover, educate the public ...

An international research team has described a newly discovered algae species Streptofilum arcticum and its cell functions ...

Within most natural assemblages a few species comprise the majority of the individuals (Figure 1; Preston 1948). This pattern in distribution of species abundances is accompanied on a larger scale ...

The newly discovered algae species Streptofilum arcticum possesses a potentially highly flexible cell wall to help it survive ...

All animals live in or seek a set of climate conditions they find tolerable. This "climate envelope" partially determines ...

By Keith Anthony Fabro Around 3.4 million years ago, a hidden evolutionary tale unfolded in the Indo-Burma region: a cryptic pangolin species diverged from the Chinese pangolin (Manis pentadactyla).

Immediately adjacent or neighboring populations of the species vary slightly but can interbreed. But at the extremes of the distribution -- the opposite ends of the pattern that link to form a ...

It consists of a container, such as a yoghurt carton, buried in the ground. The top of the container is level with the soil surface, and it is covered by a piece of wood with a slight gap to allow ...

Predicting local extinction rates is complex due to differences in biological diversity, species distribution, climate, vegetation, habitat threats, invasive species, consumption patterns, and enacted ...

If we lived in an ordinary time—time here being understood in the long, unhurried sense of a geologic epoch—it would be nearly impossible to watch a species vanish. Such an event would occur ...

Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing ...
