Comparison of the Hatch of Newly Laid Lycorma delicatula (Hemiptera: Fulgoridae) Eggs From the United States After Exposure to Different Temperatures and Durations of Low Temperature

Comparisons were made of the effects of temperature and duration of low temperature on hatch of newly laid egg masses of the invasive spotted lanternfly, Lycorma delicatula (White). Egg masses were collected in mid- October 2019 and estimated to be less than 14 d old. There was a significant positive nonlinear relationship between temperature and developmental rate (1/d) for eggs held at constant ...

Review of dam effects on native and invasive crayfishes illustrates complex choices for conservation planning

Dams are among the most prevalent and extreme alterations humans have perpetrated on fluvial systems. The dramatic physical and biological changes caused by dams have been synthesized for many aquatic faunal groups, but not for crayfishes. In addition, invasive crayfish species are an increasing threat to global biodiversity, and dams have both costs and benefits with respect to crayfish invasions...

IUFRO WP 7.03.16 & 7.03.05 – Webinar Series 2021 on Behavioral and Chemical Ecology of Bark and Woodboring Insects: Plant Defense and Biotic and Abiotic Stressors

From 2021-01-21 to 2021-01-21, , online, IUFRO Unit(s) involved: 7.03.16, 7.03.05 Climate change has a strong influence on expression and responses of plant primary and secondary metabolites. Investigating such plant responses has become more critical as the North American forests have been frequently invaded by invasive insect herbivores. Studies have either primarily focused on the effects of cl...

Figs show that nonnative species can invade ecosystems by forming unexpected partnerships

While surveying the Hawaiian island of Kauai in search of invasive plants in 2017, botanist Kelsey Brock spotted something unusal: a few nonnative species of figs seemed to be settling in....

Drought resistance and gum yield performances in a Senegalia senegal (L.) Britton progeny trial in Senegal

Abstract With continued global change as a result of land use changes, invasive species and changing climatic patterns, it is becoming increasingly important to understand the adaptability of Senegalia senegal provenances to maximize resilience in managed and natural populations of this species. The objective of this study is to investigate Senegalia senegal genotypic differences...

Dogs springing to work in detecting kauri dieback

Four-year old English springer spaniel Pip and 5-year-old terrier Mawhai are being phased into operation, which will begin with the testing of soil samples from possibly infected kauri trees. Source: Stuff NZ A select few people including Auckland mayor Phil Goff were invited to watch the dogs in action at the remote training facility in Huia. Mr Goff was impressed by the success of the program an...

Phytophthora introductions in restoration areas: Responding to protect California native flora from human-assisted pathogen spread

Over the past several years, plantings of California native plant nursery stock in restoration areas have become recognized as a pathway for invasive species introductions, in particular Phytophthora pathogens, including first in the U.S. detections (Phytophthora tentaculata, Phytophthora quercina), new taxa, new hybrid species, and dozens of other soilborne species. Res...

Proceedings of the Sixth International Workshop on the Genetics of Host-Parasite Interactions in Forestry—Tree Resistance to Insects and Diseases: Putting Promise into Practice

The Sixth International Workshop on the Genetics of Host-Parasite Interactions in Forestry: Tree Resistance: Putting Promise into Practice was held the first week of August 2018 at Deer Creek State Park in Mt. Sterling, Ohio. The workshop provided a continuing conduit for bringing together researchers, tree breeders, and forest managers to focus on perhaps the most salient action society can take ...

Save Our Species: A Blueprint for Restoring Butternut (Juglans cinerea) across Eastern North America

Butternut is a relatively uncommon hardwood tree native to eastern North America. The species' abundance has declined over the past 50 years, primarily because of an invasive pathogen (Ophiognomonia clavigignenti-juglandacearum [Oc-j]) and loss of suitable habitat for regeneration. Although genetic diversity of butternut is highest along the southern range edge, genetic diversity rangewide is...

This tree snake climbs with a lasso-like motion

Researchers have discovered that invasive brown tree snakes living on Guam can get around in a way that had never been seen before. The discovery of the snake's lasso-like locomotion for climbing their way up smooth vertical cylinders has important implications, both for understanding the snakes and for conservation practices aimed at protecting birds from them....
