Web30 de mai. de 2024 · The island species–area relationship (ISAR) is a fundamental macroecological pattern, the study of which has been closely connected with the … WebMethods: We apply 15 regression models, including linear regression and piecewise regressions with two and three segments to 68 global island datasets that are sourced from the literature. Results: The number of area thresholds in SARs varied among groups and correlated positively with area range of a studied system.

Web20 de jan. de 2024 · Growing evidence suggests that biodiversity on small islands and fragments could be independent of island area, a pattern called the Small Island Effect (SIE). We searched for SIE among the floras of 19 courtyards completely enclosed by buildings in central St Petersburg, Russia, in 1993, 2003 and 2008. WebA total of 248 specimens were analyzed 104 of Triportheus albus (25 preflexion, 18 flexion, 45 postflexion, and 16 juveniles) and 143 of T. angulatus (46 preflexion, 54 flexion, 13 postflexion, and 30 juveniles).
