Understory Plant Abundance Is More Important than Species Richness in Explaining Soil Nutrient Variation Following Afforestation on the Eastern Loess Plateau, China
afforestation soil organic carbon total nitrogen total phosphorus understory vegetation biomass
2023/12/1
Afforestation plays an important role in controlling soil erosion and nutrient loss on the Loess Plateau in China. However, previous studies on soil nutrient changes have mainly focused on the effects...
Soil community richness and composition jointly influence the?multifunctionality?of soil along the?forest-steppe ecotone
Soil biodiversity Soil multifunctionality Forest-steppe ecotone Soil micro-food web Richness Community composition

Soils harbor an enormous organism which provide multiple ecosystem functions in the terrestrial ecosystem. However, the potential effects of soil biodiversity on soil?multifunctionality?(multiple ecos...
Differential diameter-size effects of forest management on tree species richness and community structure: implications for conservation
Differential diameter-size effects tree species richness
2015/11/13
In this paper we tested the hypothesis that logging effects in the adult tree
community reverberate upon the regeneration contingent. We examined the differences on
the tree community between forest...
Size-dependent species richness:trends within plant communities and across latitude
Community ecology plant size species packing species richness
2015/8/27
We examine how species richness and species-specific plant density (number of species and number of individuals per species, respectively) vary within community size frequency distributions and across...
Variation in demersal fish species richness in the oceans surrounding New Zealand:an analysis using boosted regression trees
Demersal fish Species richness Boosted regression trees Statistical model
2015/8/21
We analysed relationships between demersal fish species richness, environment and trawl characteristics using an extensive collection of trawl data from the oceans around New Zealand. Analyses were ca...
Richness of information about novel words influences how episodic and semantic memory networks interact during lexicalization
Lexical acquisition fMRI Associative memory Complementary learning systems Overnight consolidation
2015/5/6
The complementary learning systems account of declarative memory suggests two distinct memory networks, a fast-mapping, episodic system involving the hippocampus, and a slower semantic memory system d...
Phonetic richness can outweigh prosodically-driven phonological knowledge when learning words in an artificial language
Phonetic richness outweigh prosodically-driven phonological knowledge artificial language
2015/4/20
How do Dutch and Korean listeners use acoustic–phonetic information when learning words in an artificial language? Dutch has a voiceless ‘unaspirated’ stop, produced with shortened Voice Onset Time (V...
Can clearcuts increase bird species richness in managed forests?

2015/3/12
Clearcuts are one of the results of forest management. The aim of this study was to assess the effect of clearcuts on bird communities in a managed forest in Western Poland. I applied the method of po...
“In LSLT the ` psychological analogue’ to the methodological problem of constructing linguistic theory is not discussed, but it lay in the immediate background of my own thinking. ”
INTERANNUAL VARIABILITY OF NDVI AND SPECIES RICHNESS IN KENYA
Interannual AVHRR-NDVI spatial scale birds mammals plants species richness Kenya
2015/2/4
A central task in community ecology is to determine biophysical controls of species richness patterns. Most multivariate
models relating environmental characteristics to species richness were develop...
Taxon- and vector-specific variation in species richness and abundance during the transport stage of biological invasions
Taxon- and vector-specific variation species richness abundance the transport stage of biological invasions
2014/4/2
Recent empirical and statistical evidence suggest that propagule pressure (i.e., number of individuals introduced per event, and the number and frequency of events) and colonization pressure (i.e., nu...
Mollusk Species Richness on the Rocky Shores of the State of Guerrero, Mexico, as Affected by Rains and Their Geographical Distribution
Rocky Shore Species Richness Geographic Distribution Rain Effects Mollusks
2013/3/8
Natural processes in ecosystems shows significant variations in species richness with regular cycles that can be altered by natural or anthropogenic activities; the present research was in order to un...
Optical Redshift and Richness Estimates for Galaxy Clusters Selected with the Sunyaev-Zel'dovich Effect from 2008 South Pole Telescope Observations
galaxies clusters individual ]cosmology observations
2010/3/9
We present redshifts and optical richness properties of 21 galaxy clusters uniformly selected by their Sunyaev-Zel'dovich signature. These clusters, plus an additional, unconfirmed candidate, were det...
On some Bayesian nonparametric estimators for species richness under two-parameter Poisson-Dirichlet priors
Bayesian nonparametric estimators species richness two-parameter Poisson-Dirichlet priors
2010/3/11
We present an alternative approach to the Bayesian nonparametric analysis of conditional
species richness under two-parameter Poisson Dirichlet priors. We rely on a known characteri-
