The local stability and resilience of 13 eco-social keystone species complexes (eco-social KSCs)—considered as conservation monitoring units—were quantified in coastal marine ecosystems located the Caribbean eastern Pacific. Based on Routh–Hurwitz’s criterion Levins’ criteria, KSCs corresponding to Islas Marietas National Park (Mexico) emerged most locally stable resilient ecosystem. To contrary, determined for Guala Bay (Chile) Xcalak Reef (Caribbean) were least resilient, respectively.

Fraxinus foliage: does host species during adult maturation feeding alter the fecundity of emerald ash borers, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)?

Environmental Entomology, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

Abstract Herbivorous insects can have their reproductive potential influenced by the quality and species of host plants they feed upon. The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an invasive pest trees (Fraxinus spp.) within its introduced range. As adults, EAB must upon foliage to sexually mature. We compared influence 4 North American on via feeding assess impacts female lifespan metrics. fed 136 EAB, 34 in each group, either black, green, tropical, or white throughout adult life. performed daily inspections for mortality, oviposition, egg hatching. found that mean lifespan, fertility rate, development time were not affected species. Potential realized fecundity increased with summed group (days), but this rate differed among Consequently, there was a statistically significant interaction effect foliage.

Observations of reduced ET and persistent elevated water table beneath a riparian forest gap following emerald ash borer invasion and tree mortality

Abstract Emerald ash borer (EAB) ( Agrilus planipennis Fairmaire), an invasive, phloem‐feeding beetle native to Asia, has killed millions of Fraxinus spp.) trees in North America since it was detected southeast Michigan 2002. Consistently high mortality black nigra ) and green F. pennsylvanica which often occur riparian forests is a concern given their role regulating soil moisture shallow groundwater levels. We monitored compared hydrologic processes forest impacted by EAB invasion adjacent unimpacted site southwest Michigan. From 2018 2022, we recorded moisture, depth meteorological variables at 15‐min intervals throughout the growing season canopy gap following EAB‐caused adjacent, unaffected Augusta Creek zone.

Species Preservation in the Face of Novel Threats: Cultural, Ecological, and Operational Considerations for Preserving Tree Species in the Context of Non-Indigenous Insects and Pathogens

Journal of Forestry, Journal Year: 2023, Volume and Issue: 121(5-6), P. 470 - 479

Published: June 26, 2023

Abstract Non-Indigenous insects and pathogens (NIIP) have functionally eliminated numerous tree species of immeasurable cultural ecological significance over the past century, with number introductions associated impacts growing each year. Foresters are often on frontlines these impacts, tasked quickly adapting management plans to recover potential economic losses maintain future silvicultural options following loss. We highlight that irreplaceable values provided by many argues for renewed focus applying integrated pest adaptive strategies in novel ways sustain generations. To guide efforts, we describe a framework NIIP centered three interrelated components: preservation value, approach, strategy. This emerging efforts provide an alternative path forward threatened their era increasing change. Study Implications: The impact non-indigenous is one greatest challenges facing long-term stewardship forests North America. Species apply face increasingly needed foresters’ toolboxes address threats. Identifying (ethical responsibility, integrity, function, genetic conservation) tied effort will help how approaches applied at stand landscape scales into future.

Spread management priorities to limit emerald ash borer (Agrilus planipennis) impacts on United States street trees

Abstract The invasive emerald ash borer ( Agrilus planipennis ) causes damage to street trees which is estimated reach US$ 900 million over the next 30 years. Although millions of dollars are spent annually control this species, spatiotemporal management plans often based on rules thumb that ignore future pest dispersal. Here, we reveal an optimal strategy protect urban in North America from A. . To achieve this, embedded a dispersal model within mixed integer programming framework. We discovered optimized strategies consistently outperformed those thumb, potentially resulting protection additional nearly 1 and savings $ 629 million. Critically, best always relied quarantines biological (constituting 98–99% 1–2% project budget, respectively), contrast with current practices, where federal spending has been diverted control. Our findings serve inform efforts can help many more species.

Black ash ( Fraxinus nigra Marsh.) is an important species for the W8banaki Nation, which uses its wood traditional basketry. This study aimed to identify properties required black splints used in Eleven logs were selected and pounded into 26 longitudinal groups of annual layers, then transformed splints. A quality class (high, medium, or low) was assigned by W8banakiak knowledge carriers each group rings. We measured density, ring width, modulus elasticity, rupture on samples located at same radial position bolts collected adjacently pounding. To investigate best related class, we applied a generalized linear mixed model. Our model revealed significant effect width average density probability obtain given class. Narrow- medium-sized rings relatively dense offered basketry practice. Based our results, further research effects growth conditions that favour production high-quality could be conducted ultimately propose silvicultural treatments management strategies.

Towards Tree Species Preservation: Protecting Ash Amidst the Emerald Ash Borer Invasion in the Northeast

Journal of Forestry, Journal Year: 2023, Volume and Issue: 121(5-6), P. 480 - 487

Published: June 24, 2023

Abstract The introduced emerald ash borer (EAB) represents the costliest invasive forest insect in US history, causing significant mortality of species across much eastern North America as well Colorado and Oregon. Few surviving overstory trees exist areas first invaded by EAB, such Lake States region; however, forests with healthy, mature remain recently regions, northeastern United States. Given importance to cultural lifeways Indigenous peoples ecology economies working lands, there is growing interest applying protection measures maintain forested settings. We further develop our call for preservation presenting Western science case studies ongoing efforts mitigate impacts illustrating specific applications these strategies meeting different goals lowland northern hardwood America. Study Implications: threatens functionally eliminate from large portions Although EAB are now widespread many areas, States, Northeast, still contain ash. This presents a unique opportunity apply integrated pest management knowledge gained other regions preserve ecological values provided forest. Multistakeholder partnerships built around preserving have powerful approach sustaining into future.
