Latitudinal gradient in species richness
Did you know?
WebThe latitudinal diversity gradient is one of the most striking patterns in the natural world. Hillebrand’s (2004) recent meta-analysis of almost 600 studies documents its remark-able consistency across space, scale, habitat and taxonomic group. Species richness of most taxa increases towards the Webcies richness towards north. The latitudinal gradients in species richness and diversi ty have attracted biogeographers' attention for a long time. Among the first to note the generally decreasing trends of species richness from the tropics to the poles was Wallace (1878). He, for example, stated that generally species rich
Web4 apr. 2000 · Here, we examine latitudinal patterns of diversity in the deep North Atlantic by comparing the richness and evenness components of a diversity index applied to three … Web15 aug. 2012 · The latitudinal gradient of species richness has frequently been attributed to higher diversification rates of tropical groups. In order to test this hypothesis for mammals, we used a set of 232 genera taken from a mammalian supertree and, additionally, we reconstructed dated Bayesian phylogenetic trees of 100 genera.

Webographic covariates, such as water temperature (Roy et al., 2000), yet mammal richness peaks at high latitudes (Grady et al., 2024), and more species have been reported from polar soft-sediment habitats than at many lower latitudes (Vause et al., 2024). While gradients in species diversity have received most attention, latitudinal changes ...
Webtoward the tropics (Fig. 2; Stevens and Willig, 2002). In contrast, b-diversity for species richness remained more or less constant below 30 N latitude for nonvolant mammals inNorth America (Kaufman, 1998)and did not contribute to latitudinal gradients of marsupial species richness in the New World (Willig and Gannon, 1997).
WebThe climax of global latitudinal species richness for some mangrove was observed along latitudes 20° N and 15°-25° S, not at the equator. This can suggest that temperature is probably the key driver of latitudinal gradients of mangrove crabs' species richness. Species richness and mangrove area were also highly correlated. the spice road calgaryWeb28 okt. 2024 · We observed two peaks in the species richness curves along both latitudinal and longitudinal gradient, due to harbouring of … the spice rack store brooklynWeb17 jan. 2024 · Species richness peaked in the subtropical area of the Northern Hemisphere and near the Equator, between latitudes 40° and 20° (113 species), and between latitudes 0° and 10° (124 species; Fig. 1b), and steeply decreased with latitude (r = −0.78, P < 10 −5; linear regression: intercept 103.7, slope coefficient −1.336; Fig. 4a). mysql backup and restore databaseWeb1 dag geleden · Research has shown that in ecosystems where fire is a natural and regular occurrence, there can be more species of plants — a greater “species richness” — due … mysql autoreconnectforpoolsWebUnderstanding the origins of species richness patterns is a fundamental goal in ecology and evolutionary biology. Much research has focused on explaining two kinds of species richness patterns: (i) spatial species richness patterns (e.g. the latitudinal diversity gradient), and (ii) clade-based species richness patterns (e.g. the predominance of … mysql auto increment with prefixWeb31 aug. 2024 · The latitudinal gradient in species richness is perhaps the most fundamental pattern of biodiversity, yet a satisfactory explanation for its existence remains elusive.
