What is relative abundance in ecology? Ecosystems In any ecosystem on earth, there is some element of species diversity. The diversity can vary depending on the location and type of the ecosystem and based on its boundaries. For example, one could consider the Amazon rainforest an ecosystem, ...

abundance (RSA) in the local community under restricted immigration. Here we present a theoretical framework for the unified neutral theory of biodiversity2and an analytical solution for the distribution of the RSA both in the metacommunity (Fisher's log series) and in the local community, where ...

The species composition, abundance and distribution of sea cucumbers in the intertidal zone of East Cab-ilan Island, Province of Dinagat Islands, Philippines were assessed using a transect-quadrat method. Sampling was done once at the two identified sampling stations in three replicates. A total of...
Transpirational water loss was determined by weighing pots at seven time points throughout the day under the prevailing temperature and RH % conditions, when VPD increased through the time course of the day. VPD was calculated from these temperature and relative humidity % data using the formula:...

Asian black francolin (Francolinus francolinus asiae) is an important bird species in the North Western Himalayan region, inhabiting diverse subtropical to lower temperate habitat types. The relative abundance, habitat preference and some aspects of breeding ecology are studied here at eleven sites in ...
