Significance Around the globe, climate warming is increasing dominance of warm-adapted species—a process described as “thermophilization.” However, thermophilization often lags behind itself, with some recent studies showing no response at all. Using a unique database more than 1,400 resurveyed vegetation plots in forests across Europe and North America, we document significant understory vegetation. to macroclimate was attenuated whose canopies have become denser. This microclimatic effect...
(1) The number of woodland vascular plant species in eighty-nine ancient woods and 273 recent central Lincolnshire was recorded. Ancient were identified from historical archaeological sources. (2) In both the increased with area, probably because a correlated increase habitat diversity. (3) present part an wood not significantly different whole equivalent area. (4) recently reduced which to their size long ago. This result also obtained for 'ancient species' 'recent (see (10) below)...
Following habitat fragmentation individual patches may lose species over time as they pay off their "extinction debt." Species with relatively low rates of population extinction and colonization ("slow" species) maintain debts for particularly prolonged periods, but few data are available to test this prediction. We analyzed two unusually detailed sets on forest plant distributions land-use history from Lincolnshire, United Kingdom, Vlaams-Brabant, Belgium, an debt in relation...
1 Disturbance may cause community composition across sites to become more or less homogenous, depending on the importance of different processes involved in assembly. In north-eastern North America and Europe local (alpha) diversity forest plants is lower forests growing former agricultural fields (recent forests) than older (ancient) forests, but little known about influence land-use history degree compositional differentiation among (beta diversity). 2 Here we analyse data from 1446...
Summary 1. Atmospheric nitrogen (N) deposition is expected to change forest understorey plant community composition and diversity, but results of experimental addition studies observational are not yet conclusive. A shortcoming studies, which generally based on resurveys or sampling along large gradients, the occurrence temporal spatial confounding factors. 2. We were able assess contribution N versus other ecological drivers communities by combining a approach. Data from 1205...
Summary The effect of extreme climate events on ecosystems is an important driver biotic responses to change. For forests, drought has been linked negative effects such as large‐scale mortality and reduced primary production. However, the response plant communities remains poorly understood. We used data from a long‐term monitoring programme in core focal species' ranges, combination with annual growth tree‐rings, study of, recovery from, event. examined both intraspecific interspecific...
More and more ecologists have started to resurvey communities sampled in earlier decades determine long-term shifts community composition infer the likely drivers of ecological changes observed. However, assess relative importance of, interactions among, multiple joint analyses data from many regions spanning large environmental gradients are needed. In this paper we illustrate how combining can increase likelihood driver-orthogonality within design show that repeatedly surveying across...

Of the 45 000 ac of Crown common land within New Forest more than 6000 are occupied by deciduous woodland, most notable features which widespread predominance even-aged and biologically mature beech (Fagus sylvatica) oak (Quercus robur Q. petraea) abundance holly (llex aquifolium). Holly is present in nearly all woods, many cases forming a dense understorey. It also occurs unshaded conditions as dominant species small areas scrub known locally 'holms' or 'hats': these woods have attracted...
(1) The 35-ha stand of mixed native broadleaves at Lady Park Wood was designated as an unmanaged nature reserve in 1944. It had for centuries been treated coppice or coppice-with-standards, and this enabled the mixture beech, oak, ash, lime, elm, birch, maple, hazel, etc., to survive unaffected by significant planting. (2) Part felled 1943. remainder has largely untouched since 1902, is dominated trees dating from 1800-1900; old-growth subject paper. (3) Nine transects, placed across main...
(1) The distribution of Mercurialis perennis in central Lincolnshire is described and analysed mainly terms age origin the woods hedges it inhabits. (2) 154 separate populations are divided into: (a) 119 relict populations, which could have survived on or near present location throughout historical times; (b) 35 colonizing probably become established recent centuries. (3) Survival individual ancient has not been affected by their area isolation. wood-relict may greater those least isolated...
Abstract Wild pollinators are crucial for ecosystem functioning and human food production often rely on floral resources provided by different (semi‐) natural ecosystems survival. Yet, the role of European forests, especially forest herb layer, as a potential provider has scarcely been quantified. In this study, we measured nectar (PNP) layer using resurvey data across 3326 plots in temperate forests Europe, with an average time interval 41 years between both surveys order to assess (i)...
The effects over 16 years of the 1976 drought on beech ( Fagus sylvatica L.) population in mature, mixed deciduous, semi-natural stands Lady Park Wood are described. Individual trees were recorded within sample transects at intervals from 1945 onwards, so it was also possible to examine responses relation previous growth. Many mature beeches killed immediately or severly damaged. Growth survivors negligible until about 1985 and never recovered pre-drought rates. Damaged still dying 15 later...
