Introduction
I obtained my PhD degree from the School of Biological Sciences, The University of Hong Kong in 2012. I have been doing research in plant science and bird ecology over the years. My projects included ecological succession in landslides in Hong Kong, the ecological role of birds in Hong Kong's secondary forest, bird-ringing in the artificial wetland and secondary forests, GPS-tracking of egrets.

Unlike most genera in the early-divergent angiosperm family Annonaceae, Pseuduvaria exhibits a diversity of floral sex expression. Most species are structurally andromonoecious (or possibly androdioecious), although the hermaphroditic flowers have been inferred to be functionally pistillate, with sterile staminodes. Pseuduvaria presents an ideal mo...
Annonaceae flowers are generally hermaphroditic and show high levels of outcrossing, but unlike many other early-divergent angiosperms lack a self-incompatibility mechanism. We reassess the diversity of mechanisms that have evolved to avoid self-pollination in the family. Protogyny occurs in all hermaphroditic flowers in the family, preventing auto...
Landslides often lead to a unique successional direction because the existing vegetation, seed bank and top soil including nutrient and mycorrhizal inoculum have been lost. This type of disturbance has attracted more attention in recent decades especially in mountainous regions experiencing regular severe rainstorm. In Hong Kong, urban development...
Many natural wetlands have been converted to human-influenced wetlands. In some instances, human-influenced wetlands could provide complementary habitats for waterbirds, compensating for the loss of natural wetlands. Inner Deep Bay in Hong Kong is composed of both natural and human-influenced wetlands and is under immense development pressure. From...
Along the East Asian-Australasian flyway (EAAF), waterbirds are threatened by a wide range of human activities. Studies have shown that wintering populations of many species have declined in Australia and Japan; however, long term data along China’s coast are limited. In this study, we analyzed data collected from monthly bird surveys to quantify p...
Floral mimics deceive their pollinators by developing visual and olfactory resemblance to various models. We report a flower that exhibits phenotypes like aerial litter and deceives an aerial litter specialist beetle to achieve pollination.
We assessed the floral phenology and the effective pollinators of an Australian understorey treelet, Meiogyne...
Premise
The family Annonaceae possesses a broad array of floral phenotypes and pollination specialisations, and are important in the plant-pollinator interactions of tropical rainforests. Although there has been considerable effort to assess their interactions with pollinators, attempts to characterise their visual and olfactory communication chann...
Floral mimics deceive their pollinators by developing visual and olfactory resemblance to their models. Our knowledge on the diversity of models is expanding rapidly. We report a system in which the flowers exhibit phenotypes similar to aerial litter and deceives an aerial litter specialist beetle to achieve pollination.
We assessed the floral phen...

Our study provides the first GPS tracking data of Little Egret Egretta garzetta from an East Asian population. Our two main objectives were to reveal the migratory route and migratory strategy of Little Egret, and to study inter-annual breeding and wintering site fidelity. Our data, from an adult and a juvenile, suggest that this species is a short...
Landslides are common in tropical and subtropical regions with hilly terrains and heavy rainstorms, and can cause significant economic, ecological, and social impacts. Natural forest succession is usually slow on landslide due to poor soil structure and lack of woody plant seeds, and often comes with a higher risk of repeated landslides. Active for...
Landslides are common in tropical and subtropical regions with hilly terrains and heavy rainstorms, which cause significant economic, ecological, and social impacts. Natural forest succession is usually slow on landslide scars due to poor soil structure and the lack of seeds of woody plant seeds, and often comes with a higher risk of repeated lands...
Automatic bird detection in ornithological analyses is limited by the accuracy of existing models, due to the lack of training data and the difficulties in extracting the fine-grained features required to distinguish bird species. Here we apply the domain randomization strategy to enhance the accuracy of the deep learning models in bird detection....
Ecological restoration of closed landfill sites is often challenging due to poor soil structure and seed bank. Currently, the planting mixes used in closed landfills in Hong Kong involved mainly exotic trees with only a small proportion of native trees and shrubs. In this study, we investigated the vegetation regeneration in seven closed landfill s...
Hong Kong possesses an impressively diverse tree flora with 390 native species. This book celebrates the incredible diversity, beauty and biology of the territory's tree species, highlighting over 100 important species that are individually illustrated in exquisitely detailed watercolour paintings by Sally Grace Bunker, an acclaimed botanical artis...
In Southeast Asia, intensive rainstorms caused by strong monsoon and tropical cyclones can trigger landslides in mountainous or hilly regions, which may significantly impact the natural terrains. This mostly includes the loss of vegetation cover, the emptying of seed banks and degradation of the top soil. The objective of this study was to assess t...
Although 'dry-type' stigmas are widely regarded as ancestral in angiosperms, the early-divergent family Annonaceae has copious stigmatic exudate. We evaluate three putative functions for this exudate: as a nutritive reward for pollinators; as a pollen germination medium; and as an extragynoecial compitum that enables pollen tube growth between carp...
Several evolutionary lineages in the early divergent angiosperm family Annonaceae possess flowers with a distinctive pollinator trapping mechanism, in which floral phenological events are very precisely timed in relation with pollinator activity patterns. This contrasts with previously described angiosperm pollinator traps, which predominantly func...
The floral phenology, pollination ecology and breeding systems of two sympatric early-divergent angiosperms, Goniothalamus tapisoides and G. suaveolens (Annonaceae) are compared. The flowers are protogynous and morphologically similar, with anthesis over 23–25 h. Both species are predominantly xenogamous and pollinated by small beetles: G. tapisoid...
Disepalum comprises two monophyletic sister subgenera, Enicosanthellum and Disepalum, with strikingly different floral morphologies: the former has two whorls of unfused sepals, forming a partially enclosed floral chamber, whereas the latter possesses a single whorl of congenitally fused petals and lacks a floral chamber. The pollination ecologies...
Premise of the study:
Heterotrophic angiosperms tend to have reduced plastome sizes relative to those of their autotrophic relatives because genes that code for proteins involved in photosynthesis are lost. However, some plastid-encoded proteins may have vital nonphotosynthetic functions, and the plastome therefore may be retained after the loss o...
Premise of research. Early-divergent angiosperms typically possess hermaphroditic flowers but often lack any biochemically mediated self-incompatibility mechanism. Although outcrossing is generally promoted in these taxa by protogyny, which is effective for precluding autogamy (self-fertilization within a flower), other mechanisms are necessary to...

Questions
Question (1)
I read an interesting paper (as below) and learnt that grassland habitat is continually declining in South China, largely due to reforestation schemes and vegetation succession (better hillfire control measures). Historically, grassland habitat shouldn't be that extensive in this region which likely supported fewer grassland specialists. However, the very long history of human settlement (more than 100,000 ya if we take Homo erectus into account) has favored the colonization of this group of species, including this rare Chinese Grassbird. In terms of habitat management, how should we address this apparent dilemma - to recover the ancient, original habitat of an area; OR, to actively maintain certain habitats to protect rare species, even such habitat is somewhat anthropogenically-created?
