Floral and vegetation changes during the cold stage (30–14.7 ka) of Marine Isotope Stage 2 in Japan: Evidence from plant macrofossil records and implications for plant food resource distribution

Quaternary Science Advances
During the cold stage of Marine Isotope Stage 2 (MIS 2; 30–14.7 ka), vegetation dominated by pinaceous conifers expanded across the Japanese Archipelago.

Investigation on adaptability of different coniferous species at Hamadan province of Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2006
The aim of the research was to study the adaptability of 13 needleleaved species and provenances under semi-arid and severe cold climate of Hamadan province of Iran on deep alluvial and light textured (Sandy loam) soils (pH= 7.65).

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.

Dose–response modelling uncovers compound‐specific inhibitory effects of host defence volatiles on mountain pine beetle fungal symbionts

Pest Management Science, EarlyView.
Host defence volatiles inhibit mountain pine beetle fungal symbionts in a compound‐ and enantiomer‐specific manner, with distinct dose–response profiles that reveal the multitarget chemical defences of beetle–fungi symbiotes. Abstract BACKGROUND The mountain pine beetle relies on symbiotic fungi to overcome host tree defences, yet these fungi must ...

Revealing the Application of Synchrotron‐Based X‐Ray Computed Tomography in Healthy Versus Unhealthy Interior Lodgepole Pine (Pinus contorta var. latifolia) Conelets

Plant Direct
The reproductive cycle of interior lodgepole pine spans approximately 26 months, with seed cones initiating in late summer, followed by pollen conelets emerging the next spring when pollination occurs.

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

River Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)
