Supermatrix Phylogenetic Tree of Passerine Birds From the Indo-Australian Archipelago Highlights Contrasting Histories of Regional Endemism. [PDF]

Ecol Evol
To better understand the relative histories of bird diversification in the different areas of the Indo‐Australian Archipelago (IAA) we compile an updated and as‐complete‐as‐possible supermatrix phylogeny for passerine birds from the IAA and use this to estimate the different levels of endemism in the IAA.

A Comparative Study of Seminal Plasma and Sperm Metabolome Profiles in Toraya Buffalo Bulls. [PDF]

Vet Med Int
The objective of this study was to compare the metabolomic profiles of seminal plasma and sperm in Toraya buffalo bulls to identify key metabolites that influence sperm quality and reproductive potential. Semen samples were collected from eight mature Toraya buffalo bulls aged 4–10 years and classified as Saleko and Bonga types.

Maintaining understory vegetation in oil palm plantations supports higher assassin bug numbers

Ecological Solutions and Evidence, Volume 4, Issue 4, October–December 2023., 2023
Reduced understory vegetation complexity in oil palm plantations leads to a significant drop off in numbers of assassin bugs, which are major pest control agents within the system. This suggests that maintaining understory vegetation in oil palm has the potential to boost both biodiversity and pest control.

Plant species biogeographic origin shapes their current and future distribution on the world's highest island mountain

Journal of Ecology, Volume 111, Issue 2, Page 372-379, February 2023., 2023
An expert verified list of c. 7000 herbarium specimens shows that Mount Jaya's lowland forests are dominated by species that originated further west on the islands and mainland of Sunda. At higher elevations more and more eastern, Sahulian species are present.

Rainforest conversion to smallholder cash crops leads to varying declines of beetles (Coleoptera) on Sumatra

Biotropica, Volume 55, Issue 1, Page 119-131, January 2023., 2023
This study compared canopy beetle density and diversity between lowland rainforest and the three main cash crop agriculture systems in Sumatra, Indonesia: jungle rubber agroforest, and monoculture plantations of rubber and oil palm. Focusing on the four beetle families Chrysomelidae, Curculionidae, Elateridae and Staphylinidae, we demonstrate severe ...

No evidence for trade‐offs between bird diversity, yield and water table depth on oil palm smallholdings: Implications for tropical peatland landscape restoration

Journal of Applied Ecology, Volume 59, Issue 5, Page 1231-1247, May 2022., 2022
Tropical peatlands in Indonesia have been drained to allow farmer access and improve farm yields, but we found no trade‐offs between drainage depth, yields and bird diversity on smallholder oil palm farms in our study landscape within the studied range of drainage depths.

Even small forest patches increase bee visits to flowers in an oil palm plantation landscape

Biotropica, Volume 54, Issue 1, Page 18-30, January 2022., 2022
We observed bee visits to flowers of six plant species within an oil palm plantation in Indonesian Borneo. Visitation frequency decreased with distance from forest and was highest for flowers near large, continuous forests compared to a small forest fragment.

Assessing the effects of oil palm replanting on arthropod biodiversity

Journal of Applied Ecology, Volume 58, Issue 1, Page 27-43, January 2021., 2021
Our findings indicate that total arthropod abundance is resilient to replanting of oil palm, but that replanting changes total arthropod and spider community composition and decreases spider abundance and species richness in some microhabitats. While it is somewhat encouraging from a management perspective that recommended replanting strategies ...
