Article

1. Organisms of all species must balance their allocation to growth, survival and recruitment. Among tree species, evolution has resulted in different life‐history strategies for partitioning resources to these key demographic processes. Life‐history strategies in tropical forests have often been shown to align along a trade‐off between fast growth...
Article

Tree size shapes forest carbon dynamics and determines how trees interact with their environment, including a changing climate. Here, we conduct the first global analysis of among‐site differences in how aboveground biomass stocks and fluxes are distributed with tree size. We analyzed repeat tree censuses from 25 large‐scale (4–52 ha) forest plots...
Article
The growth and survival of individual trees determine the physical structure of a forest with important consequences for forest function. However, given the diversity of tree species and forest biomes, quantifying the multitude of demographic strategies within and across forests and the way that they translate into forest structure and function rem...
Article
The relative importance of tree mortality risk factors remains unknown, especially in diverse tropical forests where species may vary widely in their responses to particular conditions. We present a new framework for quantifying the importance of mortality risk factors and apply it to compare 19 risks on 31,203 trees (1,977 species) in 14 one‐year...
Book
Malaysia Red List: Plant of Peninsular Malaysia, Vol. 1 listed 1,353 taxa from 90 families, 308 genera comprising 1293 indigenous taxa and 60 non-indigenous taxa from Peninsular Malaysia. This publication consists of two parts; Part I contains the introduction, summary and analysis of the conservation status of all assessed taxa, recommendations an...

Full-text available
When Darwin visited the Galapagos archipelago, he observed that, in spite of the islands’ physical similarity, members of species that had dispersed to them recently were beginning to diverge from each other. He postulated that these divergences must have resulted primarily from interactions with sets of other species that had also diverged across...
Article
Full-text available
Large vertebrates are rarely considered important drivers of conspecific negative density-dependent mortality (CNDD) in plants because they are generalist consumers. However, disturbances like trampling and nesting also cause plant mortality, and their impact on plant diversity depends on the spatial overlap between wildlife habitat preferences and...
Article

The Asia-Pacific Biodiversity Observation Network (APBON) was launched in 2009, in response to the establishment of the Biodiversity Observation Network under the Group on Earth Observations in 2008. APBON's mission is to increase exchange of knowledge and know-how between institutions and researchers concerning biodiversity science research in the...
Article
Full-text available
Resource allocation within trees is a zero-sum game. Unavoidable trade-offs dictate that allocation to growth-promoting functions curtails other functions, generating a gradient of investment in growth versus survival along which tree species align, known as the interspecific growth–mortality trade-off. This paradigm is widely accepted but not well...
Article
General flowering, in which hundreds of species synchronize their flowering at multi‐year intervals, is a puzzle to ecologists. It is hypothesized that species taking part in general flowering time their reproduction to meet favorable environmental conditions for seedling establishment. We tested this environmental prediction hypothesis using 14‐ye...
Article

ForestGEO is a network of scientists and long-term forest dynamics plots (FDPs) spanning the Earth's major forest types. ForestGEO's mission is to advance understanding of the diversity and dynamics of forests and to strengthen global capacity for forest science research. ForestGEO is unique among forest plot networks in its large-scale plot dimens...

Aim Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large‐scale variation and...

Airborne light detection and ranging (LiDAR) instruments have been widely used for quantification of forest biomass. This study investigated the relationships between LiDAR data and aboveground biomass (AGB). The study area is located at the 50-ha dynamic plot in a primary forest area of the Pasoh Forest Reserve, a lowland dipterocarp forest, a typ...
Article
Full-text available
1. Despite its broad implications for community structure and dynamics we lack a clear understanding of how forest productivity is partitioned among tree species. As leaf mass per unit of standing biomass declines with tree size, species achieving larger stature should show lower relative productivity as compared to smaller stature species. However...
Article

Legumes provide an essential service to ecosystems by capturing nitrogen from the atmosphere and delivering it to the soil, where it may then be available to other plants. However, this facilitation by legumes has not been widely studied in global tropical forests. Demographic data from 11 large forest plots (16–60 ha) ranging from 5.25° S to 29.25...

1.Hunting and land use change modify herbivore abundances and cause cascading effects in natural ecosystems. The outcomes for vegetation depend on changes to specific plant‐animal interactions, such as seed dispersal or predation, or physical disturbances. 2.We experimentally manipulated terrestrial wildlife populations in a primary lowland forest...

The tribe Aquilarieae of the family Thymelaeaceae consists of two genera, Aquilaria and Gyrinops, with a total of 30 species, distributed from northeast India, through southeast Asia and the south of China, to Papua New Guinea. They are an important botanical resource for fragrant agarwood, a prized product derived from injured or infected stems of...

The Loxocarpinae, also known as the “Boea group”, are the subtribe of Gesneriaceae which includes Boea and a number of segregated genera and close relatives. This group currently comprises over 200 species in 15 genera. Here we present the most up-to-date phylogeny, covering all the genera known to belong to the group, based on Bayesian inference a...

Following recent molecular phylogenetic studies in Old World Gesneriaceae the nomenclatural implications for names in Henckelia are examined. New combinations are made in Codonoboea and Loxocarpus to account for species now excluded from Henckelia. A list is presented in which the current position of all species hitherto assigned to Henckelia is gi...

The genus Thottea comprises about 35 species distributed from India throughout Southeast Asia. However, most of the species have a narrow distribution. A first molecular phylogeny based on the chloroplast trnK intron, matK gene and trnK-psbA spacer is presented and confirms the monophyly of the genus according to Hou in 1981. Earlier subdivisions i...

The polyphyletic genus Chirita is remodelled after an extensive molecular phylogenetic study of species assigned to it and to other associated genera. Most of Chirita sect. Chirita and the monotypic Hemiboeopsis are amalgamated with Henckelia sect. Henckelia, resulting in a very differently circumscribed genus Henckelia and the synonymisation of Ch...

Every inconspicuous herb, lowly shrub, scrambling climber or ephemeal aquatic plays a vital role in the complex web of life. Conserving the richness of plant biodiversity doesn’t stop at timber trees, medicinal plants and pretty or showy horticultural species, but should also involve all other plants. Sadly, many of these plants are already facing...

Sphagnum bog, a unique plant community for Peninsular Malaysia was encountered on Padang Ragut, Kelantan. Its topographical features and flora are described, and compared with padang and upper montane floras. It is postulated that the community is derived from upper montane forest and is the result of zoogenic factors, namely elephant activity.
