Cím:Species Richness Responses to Structural or Compositional Habitat Diversity between and within Grassland Patches: A Multi-Taxon Approach / Lengyel Szabolcs, Déri Eszter, Magura Tibor
Dátum:2016
ISSN:1932-6203
Megjegyzések:Habitat diversity (spatial heterogeneity within and between habitat patches in a landscape,HD) is often invoked as a driver of species diversity at small spatial scales. However, theeffect of HD on species richness (SR) of multiple taxa is not well understood. We quantifiedHD and SR in a wet-dry gradient of open grassland habitats in Hortobágy National Park (EHungary)and tested the effect of compositional and structural factors of HD on SR of floweringplants, orthopterans, true bugs, spiders, ground beetles and birds. Our dataset on 434grassland species (170 plants, 264 animals) showed that the wet-dry gradient (compositionalHD at the between-patch scale) was primarily related to SR in orthopterans, grounddwellingarthropods, and all animals combined. The patchiness, or plant association richness,of the vegetation (compositional HD at the within-patch scale) was related to SR ofvegetation-dwelling arthropods, whereas vegetation height (structural HD at the withinpatchscale) was related to SR of ground-dwelling arthropods and birds. Patch area wasrelated to SR only in birds, whereas management (grazing, mowing, none) was related toSR of plants and true bugs. All relationships between HD and SR were positive, indicatingincreasing SR with increasing HD. However, total SR was not related to HD because differenttaxa showed similar positive responses to different HD variables. Our findings, therefore,show that even though HD positively influences SR in a wide range of grassland taxa,each taxon responds to different compositional or structural measures of HD, resulting inthe lack of a consistent relationship between HD and SR when taxon responses are pooled.The idiosyncratic responses shown here exemplify the difficulties in detecting general HDSRrelationships over multiple taxa. Our results also suggest that management and restorationaimed specifically to sustain or increase the diversity of habitats are required to conservebiodiversity in complex landscapes.

Cím:Ants sow the seeds of global diversification in flowering plants / Szabolcs Lengyel, Aaron D. Gove, Andrew M. Latimer, Jonathan D. Majer, Robert R. Dunn
Dátum:2009
Megjegyzések:Background: The extraordinary diversification of angiosperm plants in the Cretaceous and Tertiary periods has produced an estimated 250,000-300,000 living angiosperm species and has fundamentally altered terrestrial ecosystems. Interactions with animals as pollinators or seed dispersers have long been suspected as drivers of angiosperm diversification, yet empirical examples remain sparse or inconclusive. Seed dispersal by ants (myrmecochory) may drive diversification as it can reduce extinction by providing selective advantages to plants and can increase speciation by enhancing geographical isolation by extremely limited dispersal distances.Methodology/Principal Findings: Using the most comprehensive sister-group comparison to date, we tested the hypothesis that myrmecochory leads to higher diversification rates in angiosperm plants. As predicted, diversification rates were substantially higher in ant-dispersed plants than in their non-myrmecochorous relatives. Data from 101 angiosperm lineages in 241 genera from all continents except Antarctica revealed that ant-dispersed lineages contained on average more than twice as many species as did their non-myrmecochorous sister groups. Contrasts in species diversity between sister groups demonstrated that diversification rates did not depend on seed dispersal mode in the sister group and were higher in myrmecochorous lineages in most biogeographic regions.Conclusions/Significance: Myrmecochory, which has evolved independently at least 100 times in angiosperms and is estimated to be present in at least 77 families and 11 000 species, is a key evolutionary innovation and a globally important driver of plant diversity. Myrmecochory provides the best example to date for a consistent effect of any mutualism on largescale diversification.
