The amniote eggshell is a fundamental aspect of the embryo life-support system, protecting it from UV light, microbes and mechanical damage, while regulating gas exchange providing calcium for growth. thickness eggshells highly diverse across modern birds influences multiple functions, yet selective pressures driving have not been clearly identified. Here, we use global dataset avian indices 42...

Semi-natural grasslands, biodiversity hotspots in Central-Europe, suffer from the cessation of traditional land-use. Amount and intensity of these changes challenge current monitoring frameworks typically based on classic indicators such as selected target species or diversity indices. Indicators based on plant functional traits provide an interesting extension since they reflect ecological str...

Abstract Current study assessed the impact of Lantana camara invasion on native plant diversity in Pothohar region Pakistan. The approach used for was random samplings and comparisons indices [number species (S), abundance (N), richness (R), evenness (J?), Shannon index (H?) Simpson dominance (?)] with two categorical factors i.e., invaded non-invaded (control). Control plots harboured by an av...

In this paper we examine the precision of six diversity indices, four of them empirical when including in their formulae climax adaptation numbers. These numbers define the succession position of the plant species in five forest areas in Sao Paulo State. We simulated hypothetical forests and compared the results with a list of species in the five areas. Low agreement was found among the indices...

OBJECTIVES The marine benthic nitrogen cycle is affected by both the presence and activity of macrofauna and the diversity of N-cycling microbes. However, integrated research simultaneously investigating macrofauna, microbes and N-cycling is lacking. We investigated spatio-temporal patterns in microbial community composition and diversity, macrofaunal abundance and their sediment reworking acti...

Biodiversity being a multidimensional property is always considered as tough to measure or quantify mostly because of the assortment indices recommended for this purpose. However, there no agreement about which are more appropriate and informative. Arthropods one groups that have evaded knowledge human beings their role in ecosystem function. We used data collected from floricultural ecosystems...
