Extinction debt: a challenge for biodiversity conservation.
TLDR
Standardized long-term monitoring, more high-quality empirical studies on different taxa and ecosystems and further development of analytical methods will help to better quantify extinction debt and protect biodiversity.
Slow response of plant species richness to habitat loss and fragmentation.
TLDR
The response of vascular plant species richness to long-term habitat loss and fragmentation of Estonian calcareous grasslands (alvars) and the magnitude of extinction debt in local communities is examined.
Ecological assembly rules in plant communities—approaches, patterns and prospects
TLDR
This work redefined the traditional concept of assembly rules in a more general framework where the co‐occurrence of species is a product of chance, historical patterns of speciation and migration, dispersal, abiotic environmental factors, and biotic interactions, with none of these processes being mutually exclusive.
LOCAL PLANT DIVERSITY PATTERNS AND EVOLUTIONARY HISTORY AT THE REGIONAL SCALE
TLDR
Local relationships between plant diversity and soil pH are clearly related to evolutionary history, and the direction of the relationship between richness and pH depends on whether the species pool has evolutionary origin on soils of high or low pH.
Plant species richness: the world records
TLDR
Very high richness at any spatial grain is found only in two particular habitat/community types, and these high richness values form a very strong, consistent pattern, not greatly affected by the method of sampling, and this pattern extrapolates amazingly well.
Habitat fragmentation causes immediate and time-delayed biodiversity loss at different trophic levels
TLDR
Present-day species richness of long-lived vascular plant specialists was better explained by past than current landscape patterns, indicating an extinction debt, while short-lived butterfly specialists showed no evidence for an extinction Debt at a time scale of c.
Global assessment of arbuscular mycorrhizal fungus diversity reveals very low endemism
TLDR
The wide distribution of plant-root fungal symbionts seems to be driven by recent dispersal rather than ancient tectonics, and it is suggested that the biogeography of AM fungi is driven by unexpectedly efficient dispersal, probably via both abiotic and biotic vectors, including humans.
Environmental heterogeneity, species diversity and co‐existence at different spatial scales
TLDR
It is concluded that processes other than niche limitation can affect the relationship between heterogeneity and diversity, and novel theories for small-scale species co-existence that explain both positive and negative HDR are provided.
Integrative modelling reveals mechanisms linking productivity and plant species richness
TLDR
It is found that an integrative model has substantially higher explanatory power than traditional bivariate analyses and several surprising findings that conflict with classical models are revealed.
Contrasting plant productivity-diversity relationships across latitude: the role of evolutionary history.
TLDR
The shape of the productivity-diversity relationship differs between temperate and tropical regions and the different evolutionary history of the local species pools is a probable cause for the difference.
