Web1 dec. 1999 · We developed a hierarchical model to evaluate the degree to which area (based on a nested series of quadrats of five sizes, 1000–25000 km 2) affects the latitudinal gradient in species richness. The model allows the relationship between latitude and area to be nonlinear and, in its simple form, evaluates how well species … Web1 dag geleden · At the community level, the latitudinal diversity gradient describes the general pattern of increasing species richness, abundance, and evenness with decreasing elevation [37] and latitudes [38]. This was observed in several host-parasitoid systems and gall-inducing cynipid parasitoids (Chalcidoidea) over an altitudinal gradient of 1000m in …
Web1 dec. 2024 · Aim A latitudinal gradient in species richness, defined as a decrease in biodiversity away from the equator, is one of the oldest known patterns in ecology and … Web1 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 to a variety of factors, including fire-related adaptations. But, he said, there hasn’t been nearly as much research in the way of animal biodiversity and fire.
WebWe use a simulation model to examine four of the most common hypotheses for the latitudinal richness gradient and identify patterns that might be diagnostic of those four hypotheses. The hypotheses examined include (1) tropical niche conservatism, or the idea that the tropics are more diverse because a tropical clade origin has allowed more time … Web20 mei 2014 · The latitudinal species richness gradient in New World woody angiosperms is consistent with the tropical conservatism hypothesis May 2014 …
WebThe six major hypotheses of the control of species diversity are restated, examined, and some possible tests suggested. Although several of these mechanisms could be operating simultaneously, it is instructive to consider them separately, as this can serve to clarify our thinking, as well as assist in the choice of the best test situations for ...
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. jory shoellWebThe 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. jory sherman westernsWeb1 aug. 2000 · Species-richness Gradient Rosenzweig 1, 2 has added much needed focus to discussions of the mechanisms that generate latitudinal gradients in taxon richness. how to join marine corps sports teamsWeb19 feb. 2024 · These results do not support 'historical' hypotheses for the latitudinal diversity gradient, because neither local species richness … how to join marine corps wrestling teamWeb20 mei 2014 · Here, we use latitudinal distributions for over 12,500 woody angiosperm species in the New World and a fossil-calibrated supertree (18–21) resolved to the family … how to join man city football academyWeb10 feb. 2024 · While some studies have found evidence of a potential role for MDE in latitudinal gradients of species richness, particularly for wide-ranging species (e.g. Jetz and Rahbek 2001, Koleff and Gaston 2001, Lees and Colwell, 2007, Romdal et al. 2005, Rahbek et al. 2007, Storch et al. 2006; Dunn et al. 2007) others report little … jory smithWeb1 aug. 2000 · Three possible explanations have been proposed for why a latitudinal species-richness gradient might be expressed: first, low productivity at high latitudes … jory sormail sicoval
