“…We had therefore expected a shift towards lower wood density and higher specific leaf area at the community level through the recruitment of fast‐growing species, at least in the first year after the storm. Supporting evidence for this came from other wind disturbance (Curran et al., ; Monoy et al., ) and chronosequence studies (Craven et al., ; Lohbeck et al., ). While fast‐growing species with lower wood density such as Archidendron clypearia and a few Macaranga spp.…”

“…The method has previously been used to illustrate changes in species (taxonomic) composition over time after treatment(s), e.g., succession after restoration (Alday & Marrs, ; Bourgeois, Vanasse, González, Andersen, & Poulin, ), but has not yet been used to directly show changes in functional composition. Previous studies examining functional composition along temporal or successional gradients typically model the community‐weighted mean (Lavorel et al., ) functional trait values as univariate responses (e.g., Craven, Hall, Berlyn, Ashton, & van Breugel, ; Lohbeck et al., ; Monoy et al., ). On the other hand, treating functional composition as a collective suite of response variables in a multivariate analysis could reveal the coordinated changes between different traits that would reflect holistic shifts in functional strategy (Laughlin, ; Muscarella & Uriarte, ).…”

“…In the hurricane‐free parts of Southeast Asia, anecdotal accounts of blowdown events have documented severe structural changes and large‐scale gap formation in the affected areas, such as in Kelantan, Peninsular Malaysia (Browne, ; Wyatt‐Smith, ) and Kalimantan, Indonesia (Proctor et al., ). There is a general lack of attempts to understand community assembly processes following windstorms in tropical Asia compared to the Neotropics (Monoy, Tomlinson, Iida, Swenson, & Slik, ). It also not known if hurricane‐free forests respond to strong wind events in the same way as in the better‐studied hurricane‐prone forests.…”

Questions:How do abiotic conditions, forest structure, as well as taxonomic and functional diversities and composition recover after wind-generated treefalls? Do young and old-growth secondary forests differ in their responses?Location: Mandai region of the Central Catchment Nature Reserve, Singapore, where extensive treefalls occurred during an unusually powerful windstorm in 2011. Southeast Asia.Methods: Soil nitrogen, phosphorous, potassium, canopy cover, leaf litter depth, coarse woody debris, and woody stems ≥1-cm diameter were measured and identified in 10 × 10 m plots. Twenty-six plots were located in treefall areas and 14 plots were located in relatively unaffected areas, with equal numbers in young and old-growth secondary forest types. The first round of surveys took place within 3-6 months of the windstorm event and yearly re-surveys were conducted until 2015. Specific leaf area, leaf dry matter content, leaf thickness, woody density, maximum plant height, and seed dry mass were measured or derived from various sources. Results:There was a pulse of soil nutrient availability in both affected and unaffected areas 1 year after the wind event. Canopy cover and basal area in the affected areas recovered to similar levels as unaffected areas by the second year, and coarse woody debris by the fourth year. In affected plots, taxonomic and functional diversities increased and overshot that of-and taxonomic composition diverged from-unaffected plots after the second year. Young and old-growth secondary forest types mainly differed in the taxonomic composition of new recruits. However, there was no evidence of changes in functional composition towards resource-acquisitive strategies such as lower wood density or higher specific leaf area. Conclusions:Abiotic conditions and basal area recovered rapidly within 2-4 years after the windstorm. Taxonomic composition in young and old-growth affected forests both diverged from unaffected forests but also from each other over time.

“…Cyclonic storms also shape the functional composition of forests in space and time. Cyclonic storms create selection pressures, both in the short term via mortality and reduced reproduction and over the longer-term through facilitated recruitment, favoring pioneer species with less dense wood, higher specific leaf area and other functional traits associated with a pioneer life-history (e.g., low seed mass) [5,16,17,21]. Via canopy defoliation, cyclonic storms directly increase light penetration into the forest, which can result in an increase in the specific leaf area of surviving trees and recruits [12,22].…”

As cyclonic wind storms (hurricanes and typhoons) increase in frequency and intensity with climate change, it is important to understand their effects on the populations and communities of tropical trees they impact. Using tree demographic data from four large, tropical forest dynamics plots that differ in cyclonic storm frequency, we compare tree population and community dynamics. Additionally, we assess the effect of cyclonic storms on three functional traits, specific leaf area, wood density, and tree height of the dynamic tree assemblages. Mortality, growth and recruitment rates and the intrinsic rates of population growth of species differed across the plots, and were most dynamic, especially for stems 1-2 cm in diameter, at the plot which had an intermediate level of cyclonic storm frequency. Functional assemblages of species had the greatest degree of temporal variation in relation to disturbance, as measured by the change in functional divergence for the two plots with more intermediate cyclonic storm recurrence. Therefore, cyclonic storms affecting these plots generally have a greater effect on forest composition and dynamism than comparable cyclonic storms do on the plot which experiences cyclonic storms more frequently. Thus, we provide some evidence that community-wide demographic resistance to cyclonic storms is generally lower at an intermediate frequency of storms. While cyclonic storm strength and timing are important determinants of the

“…Similarly, large turnover in TD might be a result of gain and loss in phylogenetically or functionally redundant (dark brown) or distinct (green) diversity. currently often restricted to either plants in small-scale experimental plots (Swenson, 2011;Swenson et al, 2012) or small spatial extents in disturbance-prone regions (Monoy et al, 2016). Assessments of change in functional and phylogenetic attributes of faunal communities across sufficiently large spatial and temporal scales are scarce and rarely exceed a spatial extent of small European country or a temporal span of 25 years (Kampichler et al, 2012;Petchey et al, 2007; but see Schipper et al, 2016).…”

A near half‐century of temporal change in different facets of avian diversity

Assessments of spatial patterns of biodiversity change are essential to detect a signature of anthropogenic impacts, inform monitoring and conservation programs, and evaluate implications of biodiversity loss to humans. While taxonomic diversity (TD) is the most commonly assessed attribute of biodiversity, it misses the potential functional or phylogenetic implications of species losses or gains for ecosystems. Functional diversity (FD) and phylogenetic diversity (PD) are able to capture these important trait-based and phylogenetic attributes of species, but their changes have to date only been evaluated over limited spatial and temporal extents. Employing a novel framework for addressing detectability, we here comprehensively assess a near half-century of changes in local TD, FD, and PD of breeding birds across much of North America to examine levels of congruency in changes among these biodiversity facets and their variation across spatial and environmental gradients. Time-series analysis showed significant and continuous increases in all three biodiversity attributes until ca. 2000, followed by a slow decline since. Comparison of avian diversity at the beginning and end of the temporal series revealed net increase in TD, FD, and PD, but changes in TD were larger than those in FD and PD, suggesting increasing biotic homogenization of avian assemblages throughout the United States. Changes were greatest at high elevations and latitudes - consistent with purported effects of ongoing climate change on biodiversity. Our findings highlight the potential of combining new types of data with novel statistical models to enable a more integrative monitoring and assessment of the multiple facets of biodiversity.
