Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

Terrestrial laser scanning-based allometric models for East-African tropical rainforest trees

open access: yesTrees, Forests and People
An in-depth understanding of tree allometry is a crucial prerequisite to quantify the role of tropical forests in global carbon cycling. Here, we present site-specific, multi-species allometric models to quantify height, crown length, crown projection ...

Germination of acorns and development of oak seedlings (Quercus robur L.) following flooding

open access: yesJournal of Forest Science, 2007
Seeds and seedlings of Quercus robur, a characteristic tree species of the hardwood floodplain forests along the Rhine River, demonstrated high resistance to complete inundation under controlled conditions.

Space evidence of enhanced photosynthetic carbon uptake under fragmented temperate forests

open access: yesEnvironmental Research Letters, 2022
Global changes arouse large-scale fragmentation of forests, which has a profound impact on the balance of the global carbon cycle. However, the effect and process of temperate forest fragmentation on photosynthetic carbon uptake are not clear.

Human Impacts on Forest Biodiversity in Protected Walnut-Fruit Forests in Kyrgyzstan [PDF]

open access: yes, 2014
We used a spatially explicit model of forest dynamics, supported by empirical field data and socioeconomic data, to examine the impacts of human disturbances on a protected forest landscape in Kyrgyzstan.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Distinct Climate Effects on Dahurian Larch Growth at an Asian Temperate-Boreal Forest Ecotone and Nearby Boreal Sites

open access: yes, 2021
Climate change is exerting profound impacts on the structure and function of global boreal forest. Compared with their northern counterparts, trees growing at the southern boreal forest and the temperate-boreal forest ecotone likely show distinct ...

Functional Diversity and Oleaginous Potential of Fungal Strains From Hawaiian Soil Ecosystems

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Fungi represent an important but underexplored resource for microbial lipid production, including nutritionally valuable polyunsaturated fatty acids. Hawaiian soils, shaped by volcanic parent materials and strong environmental gradients, provide a unique setting for discovering functionally diverse fungal strains with distinct metabolic traits.
