The Point Count Transect Method for Estimates of Biodiversity on Coral Reefs: Improving the Sampling of Rare Species. [PDF]
PLoS ONE, 2016 Understanding patterns in species richness and diversity over environmental gradients (such as altitude and depth) is an enduring component of ecology. As most biological communities feature few common and many rare species, quantifying the presence and ...

A metagenomics transect into the deepest point of the Baltic Sea reveals clear stratification of microbial functional capacities. [PDF]
PLoS ONE, 2013 The Baltic Sea is characterized by hyposaline surface waters, hypoxic and anoxic deep waters and sediments. These conditions, which in turn lead to a steep oxygen gradient, are particularly evident at Landsort Deep in the Baltic Proper.

Fine intervals are required when using point intercept transects to assess coral reef status
Frontiers in Marine Science, 2022 The Point Intercept Transect (PIT) method has commonly been used in recent decades for estimating the status of coral reef benthic communities. It is a simple method that is efficiently performed underwater, as benthic components are recorded only as ...

Improved Needle Point Frames for Exact Line Transects [PDF]
Journal of Range Management, 1972 An improved needle point frame for exact line transects in dense herbaceous vegetation was developed (Fig. 1). The apparatus consists of a rigid duralumin bar (B) of about 2.40 m long, with rectangular section (10 cm x 1.8 cm) bounded, at both ends, by a tightening nut system (S).
