From mountaintops to metacollections: using genomics to evaluate strengths and gaps in the establishment of ex situ conservation collections. A case study from tropical montane cloud forest plants

Manuela Cascini, Lalita Simpson, Stuart Worboys, Warren Worboys et autres

Abstract A core aim of ex situ conservation is to represent wild genetic diversity in managed living collections. For the climate-threatened tropical montane cloud forest (TMCF) flora of northeast Australia, an ex situ metacollection of plants and seeds has been established by …

El Niño Drought Affects Tree Mortality in New Guinea Forest

Hayden Wagia, Pavel Fibich, Fanie Venter, Mex Peki et autres

ABSTRACT Climate change is increasing drought frequency and intensity in many tropical forests. It remains uncertain how the changing patterns of drought may impact the forests of New Guinea where rugged terrain provides contrasting wetness conditions. We examined mortality responses of 21,102 …

Aridity-related differences in soil elemental ratios reshape microbial functional traits across global biomes

Chunkai Li, Youzhi Feng, Tadeo Sáez‐Sandino, Chao Xiong et autres

Aridity alters soil carbon (C), nitrogen (N) and phosphorus (P) stoichiometry, yet the implications of these processes for soil microbial functional traits and potentials at the genomic level remain poorly synthesized. Here we combine measurements of soil C, N and P pools …

Functional restructuring of the global soil microbiome under multiple stressors

Ruirui Chen, Shuhong Luo, Youzhi Feng, Fernando T. Maestre et autres

Microbes, as the planet’s most abundant and diverse organisms, drive soil functions globally and are vulnerable to environmental stressors triggered by global change. Yet, knowledge regarding the impacts of multiple environmental stressors on their functional profiles as well as the consequences for …

An invasive plant may overcome pollination specialisation with a versatile breeding system

Laura C. Lopresti, Lori Lach, Paula Sosenski, Víctor Parra‐Tabla et autres

Abstract Plants with specialised pollination syndromes are less likely to become invasive compared to those with generalist syndromes, yet some highly invasive species have specialised syndromes. Few empirical studies have investigated the reproductive biology of invasive plants with specialised pollination syndromes, preventing …

A Bibliometric Analysis of Research Development for Authentication and Detection of Adulteration of Garcinia atroviridis Griff. ex T.Anderson

Anshary Maruzy, Merry Meryam Martgrita, Agung Eru Wibowo, Dyah Subositi et autres

Garcinia atroviridis Griff. ex T.Anderson is a traditional medicinal plant in Indonesia, highly valued for its fruit as a spice and an anti-obesity herbal ingredient due to its rich content of organic acids and secondary metabolites (e.g., hydroxycitric acid, flavonoids). Its popularity …

Phylogenomics of the mega genus Bulbophyllum (Orchidaceae) with implications for infrageneric classification in the Asian clade

Consolata Nanjala, Lalita Simpson, Ai-Qun Hu, Vidushi Patel et autres

Abstract Understanding evolutionary relationships in hyperdiverse plant groups remains a major challenge in systematics. The orchid genus Bulbophyllum , the second largest genus of flowering plants, represents an exceptional example of phylogenetic and morphological complexity. Relationships, particularly within the species-rich Asian clade, …

No evidence for missed mutualists in an invasive plant with the buzz pollination syndrome

Laura C. Lopresti, Daniel Montesinos, Paula Sosenski, Víctor Parra‐Tabla et autres

Abstract The missed mutualist hypothesis predicts that the absence of mutualistic partners poses a barrier to introduced species becoming invasive. Yet, some alien plants thrive despite potential dependence on certain pollinators. For example, buzz‐pollinated plants typically have specialist floral morphologies and benefit …

Germination of Dracophyllum sayeri F.Muell. (Ericaceae), a vulnerable montane cloud forest endemic

Amelia V. Stevens, Bree‐Ann Lautgier, Gemma L. Hoyle, Lydia K. Guja et autres

Abstract Climate change in tropical montane cloud forest (TMCF) is predicted to impact species adapted to consistent, mild temperatures. We used a temperature gradient plate to investigate the effect of temperature on germination and early seedling survival of Dracophyllum sayeri (Ericaceae), a …

A Typology of Australian Terrestrial Bird Communities

Martine Maron, Karlina Indraswari, Jonathan Mills‐Anderson, Courtney B. Melton et autres

ABSTRACT Aim Holistic measurement of the response of fauna communities to interventions requires suitable community condition metrics. However, the development of such metrics is hindered by the absence of broad‐scale typologies at suitable spatial and ecological resolutions. We aimed to derive a …

Tolerance of intraspecific competition contributes to invasion success, despite drought and inbreeding

Laura C. Lopresti, Lori Lach, Daniel Montesinos

Inbreeding, intraspecific competition, and drought stress interact to shape plant fitness, species distributions, and ecosystem structure. However, it is uncommon for studies to examine more than one or two of these factors simultaneously. We conducted a common garden experiment to assess the …
