Fostering landscape resilience and species conservation in frequent fire landscapes Fostering landscape resilience and species conservation in frequent fire landscapes
Restoration of dry forest landscapes of the Pacific Northwest often involves the removal of some closed-canopy forest that has expanded due to fire exclusion, but this can conflict with species conservation when species require closed-canopy forest as part of their habitat. Fire refugia—areas within fire perimeters that burn less severely or frequently—might provide a solution to this...

Long-term monitoring and response of Papaipema sciata Bird (Lepidoptera: Noctuidae) to prescribed fire in Michigan (USA) Long-term monitoring and response of Papaipema sciata Bird (Lepidoptera: Noctuidae) to prescribed fire in Michigan (USA)
The Culver’s root borer moth (Papaipema sciata) (Lepidoptera: Noctuidae) is a rare Noctuid that requires Culver’s root (Veronicastrum virginicum) to complete its lifecycle within remnant native grasslands and open woodlands in the midwest and northeast United States. We report on 26 years of monitoring this species’ colonization of Culver’s root stems at Algonac State Park (ASP) in...

Rewilding the upper Klamath River Basin: Rapid recolonization of Chinook salmon following the world’s largest dam removal Rewilding the upper Klamath River Basin: Rapid recolonization of Chinook salmon following the world’s largest dam removal
Habitat fragmentation is a global driver of decline in biodiversity, yet evaluations of ecological response following re-connection remain rare. In 2024, four hydroelectric dams on the Klamath River were removed, reconnecting over 640 km of anadromous habitat and marking the largest dam removal project completed to date. We used a stationary high-resolution multi-beam imaging SONAR to...

Age and colony variation in Adélie penguin metapopulation vital rates: Insights from a 25-year mark–recapture study Age and colony variation in Adélie penguin metapopulation vital rates: Insights from a 25-year mark–recapture study
Understanding how vital rates vary with age, life-history stage, and among populations is fundamental for predicting the demographic consequences of environmental change, especially in longer-lived species with complex life histories. These species often exhibit delayed maturity and iteroparity, making nuanced demographic insights critical for assessing their long-term viability. This...

Listening for extinction: Range-wide occupancy highlights critical risks and priorities for northern spotted owls Listening for extinction: Range-wide occupancy highlights critical risks and priorities for northern spotted owls
The northern spotted owl (Strix occidentalis caurina) continues to decline across its range, threatened by habitat disturbances and invasive barred owls (Strix varia). We conducted a range-wide spotted owl occupancy assessment using 2.1 million h of passive acoustic recordings from 4081 survey stations within 1027 randomly selected 5-km2 hexagons across six physiographic regions...

Black rails in Baja California Black rails in Baja California
Summarizing records from 1905 to 2025, we document the presence and distribution of the California black rail (Laterallus jamaicensis coturniculus) in northwestern México, particularly Baja California and the Colorado River Delta. This subspecies has a restricted distribution in the western U.S. and northwestern México. We found few records over the past century: sparse detections in the...

Modeling observational uncertainty improves estimation of breeding-season parameters that inform lek-based monitoring for Centrocercus urophasianus (Greater Sage-Grouse) Modeling observational uncertainty improves estimation of breeding-season parameters that inform lek-based monitoring for Centrocercus urophasianus (Greater Sage-Grouse)
Counts of males on leks are widely used as abundance indices to monitor populations of lek-breeding species, but they can be influenced by variation in male attendance, inter-lek movement, and mortality. When there is imperfect observability of males on leks, estimates of lek attendance and inter-lek movement are likely to be biased low. We compared traditional multi-state mark–recapture...

Ringtail (Bassariscus astutus) survival in southwestern Oregon Ringtail (Bassariscus astutus) survival in southwestern Oregon
The effective conservation and management of small carnivore populations requires understanding species’ life-history traits and identifying important vital rates that drive population trajectories. However, many of these species are rare or elusive and of state or federal conservation concern, and demographic information is often lacking and difficult to obtain. At the northern limit of...

Family life is critical for migration and survival in a long-lived social bird Family life is critical for migration and survival in a long-lived social bird
Extended parental care is common among birds and particularly well known among long-lived migratory species. Yet, factors influencing the duration of parental care are poorly understood, and empirical evidence for the functional importance of family life for offspring development is scarce. Using unique tracking and genetic data of 55 adult and juvenile migratory Bewick’s swans, among...

Competition between invasive round goby and native slimy sculpin in a coldwater laboratory setting Competition between invasive round goby and native slimy sculpin in a coldwater laboratory setting
Slimy sculpin (Cottus cognatus) abundance has substantially declined in many regions of the Laurentian Great Lakes coincident with the arrival and range expansions of invasive round goby (Neogobius melanostomus). Previous studies have shown that round goby can outcompete native mottled sculpin (C. bairdii) for shelter and negatively affect native spoonhead sculpin (C. ricei) growth, but...
