Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

A robust method for mapping refugial capacity in montane forests

Conservation Science and Practice, EarlyView.
We developed a refugial capacity analysis to guide management strategies to protect montane forests that will be relatively buffered from disturbances. Through sensitivity analyses, we found that our approach was robust to uncertainty in thresholds and climate forecasts, consistently identifying refugia across the landscape in similar locations and ...

Data for: Anomalous outbreaks of an invasive defoliator and native bark beetle facilitated by warm temperatures, changes in precipitation, and interspecific interactions

, 2019
Data were analyzed to quantify spatiotemporal patterns of two biotic disturbance agents, the invasive larch casebearer (Coleophora laricella Hübner) and native eastern larch beetle (Dendroctonus simplex LeConte), on eastern larch (Larix laricina (Du Roi)

Kernel-Based Early Detection of Forest Bark Beetle Attack Using Vegetation Indices Time Series of Sentinel-2

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The European spruce bark beetle (Ips typographus L.) is a biotic disturbance that devastates forest environmental services, and its activities are exacerbated due to climate change. Accordingly, researchers seek workflows using remote sensing imagery for

Impacts Of The Invasive FourEyed Fir Bark Beetle (Polygraphus Proximus Blandf.) On Siberian Fir (Abies Sibirica Ledeb.) Forests In Southern Siberia

Geography, Environment, Sustainability, 2019
The emergence and spread of non-native invasive forest insects represent a major potential threat to global biodiversity. The present study examines the current invasion of the far eastern four-eyed fir bark beetle Polygraphus proximus Blandf.

Protecting temperate old‐growth forests as biotic microrefugia amid climate change

Conservation Science and Practice, EarlyView.
Old‐growth forests are essential biotic microrefugia, providing high carbon storage, biodiversity, and stable microclimates that protect understorey species from climatic extremes. Their resilience to drought and disturbance makes them more effective than younger forests, yet habitat loss, fragmentation, and climate change increasingly threaten these ...

Early Detection of Bark Beetle Green Attack Using TerraSAR-X and RapidEye Data

Remote Sensing, 2013
Bark beetles cause widespread damages in the coniferous-dominated forests of central Europe and North America. In the future, areas affected by bark beetles may further increase due to climate change. However, the early detection of the bark beetle green

A DNA‐based phylogeny confirms the occurrence of Pseudips mexicanus (Hopkins, 1906) (Coleoptera: Curculionidae: Scolytinae: Ipini) in Ireland

EPPO Bulletin, EarlyView.
Abstract Specimens of an unknown Ipini were trapped during 2023–2024 exotic forest pest surveys in County Clare, Ireland. This non‐native species was provisionally identified as Pseudips mexicanus (Hopkins, 1906) with morphological identification keys. However, damaged specimens could not be confidently identified to the species level.
