Statistically rigorous methods for summarizing and reporting trends in the intactness of biodiversity are a key element of effective biodiversity monitoring programs. There are four major approaches for translating complex monitoring data into easily communicated summary statistics: (1) traditional diversity indices such as species richness and Simpson's diversity, (2) species intactness indices based on occurrence, (3) species intactness indices based on abundance, and (4) multivariate community indices. We use simulated data to evaluate the effectiveness of 13 indices from these four categories based on statistical robustness, sensitivity to errors and noise in the data, ecological relevance, and ease of communication. We show that indices that calculate species intactness using equations like Buckland's arithmetic mean index are the most effective for use in large-scale biodiversity intactness monitoring programs. Traditional diversity indices are unsuitable for monitoring of biodiversity intactness, and multivariate indices can be highly sensitive to errors and noise in the data. Finally, we provide guidelines for the application of these indices in biodiversity intactness monitoring. (C) 2008 Elsevier Ltd. All rights reserved

Coat color mismatch improves survival of a keystone boreal herbivore: Energetic advantages exceed lost camouflage

Joanie L. Kennah, Michael J. L. Peers, Eric Vander Wal, Yasmine N. Majchrzak, Allyson K. Menzies, Emily K. Studd, Rudy Boonstra, Murray M. Humphries, Thomas S. Jung, Alice J. Kenney, Charles J. Krebs, Stan Boutin

Summary: Climate warming causes asynchronies between animal phenology and environments, and mismatched traits may decrease survival. However, coat color change can provide advantages other than camouflage. In this study, we found that mismatched snowshoe hares in Yukon had a significantly reduced autumn mortality risk, possibly due to the increased coat insulation and lower metabolic rates of winter-acclimatized hares. Mismatched hares also foraged less and had lower predation risk, leading to higher survival rates. However, mismatch did not affect spring mortality risk, suggesting a potential temperature limit where the costs of conspicuousness outweigh energetic benefits.

Where to begin? A flexible framework to prioritize caribou habitat restoration

Melanie Dickie, Caroline Bampfylde, Thomas J. Habib, Michael Cody, Kendal Benesh, Mandy Kellner, Michelle McLellan, Stan Boutin, Robert Serrouya

Summary: Habitat loss is a major threat to species at risk, and habitat restoration is essential for the recovery of woodland caribou populations in Western Canada. An algorithm was developed to prioritize restoration efforts and monitor progress. The algorithm ranked landscape units into five zones of restoration priority based on maximizing gain in unaltered caribou habitat per unit cost. Ambitious and coordinated restoration efforts are needed to meet habitat management targets and minimize alteration within caribou range.

Phenotype-environment mismatch errors enhance lifetime fitness in wild red squirrels

Lauren Petrullo, Stan Boutin, Jeffrey E. Lane, Andrew G. McAdam, Ben Dantzer

Summary: This study shows that phenotype-environment mismatch errors in wild red squirrels can be explained by asymmetrical costs of different types of errors. Mothers that mistakenly increased reproductive effort when signals of an upcoming food pulse were absent were more likely to correctly increase effort when a food pulse did occur. However, mothers that failed to increase effort when cues of an upcoming food pulse were present suffered lifetime fitness costs that could only be offset through food supplementation. Therefore, these phenotype-environment mismatches may reflect a bias to overestimate environmental cues and avoid making the costliest error, ultimately enhancing lifetime fitness.

Rocks, lichens, and woody litter influenced the soil invertebrate density in upland tundra heath

Olukayode O. Jegede, Katherine M. Standen, Steven Siciliano, Eric G. Lamb, Katherine J. Stewart

Summary: Soil invertebrates play important roles in Arctic ecosystems, but studies on them are limited and our understanding of their drivers and communities is lacking. We examined soil invertebrates in Nunavut Canada and found that vegetation and substrate cover, soil nutrients and pH were the drivers of the community. Rocks, woody litter, and lichen cover had significant positive influences on the density of all studied invertebrates. Mites and collembolans were associated with lichen cover, while enchytraeids were associated with woody litter and rocks. Anthropogenic and/or natural disturbances may impact soil invertebrates and the ecosystem services they provide.

Wildfire-Grazing Impact on Forage Quality Assessed with Near-Infrared Spectroscopy and Generalized Partial Least Squares Regression

Roy Vera-Velez, Sera A. Grover, Brendan K. Bischoff, Cameron N. Carlyle, Eric G. Lamb

Summary: Fire and grazing play important roles in shaping plant community structure, influencing the quantity and quality of forage in the Great Plains ecoregion. This study examined the effects of fire on forage quality in the northern mixed-grass prairie over a 4-year period, considering the impact of grazing as well. The results show annual variations in crude protein and fiber content after wildfires, with no significant influence of grazing on forage quality. The study also suggests that fire may enhance forb digestibility and impact the grazing behavior of large ungulate grazers.

Reintroducing Vascular and Non- Vascular Plants to Disturbed Arctic Sites: Investigating Turfs and Turf Fragments

Ian G. Hnatowich, Eric G. Lamb, Katherine J. Stewart

Summary: Disturbed low-Arctic environments pose challenges for ecological restoration, but transplantation of whole-turfs and shredded turfs from undisturbed tundra can effectively promote plant establishment and development. After two years, the transplanted turfs maintained a high percentage of vegetative cover and species richness, expanding into the surrounding substrate. While shredded turfs had difficulty establishing vascular species, they may be more successful in establishing non-vascular plant cover with better environmental protection. These results highlight the potential of turfs in providing native species for disturbed areas and promoting sustainable development of vegetation.

Prioritizing populations based on recovery potential

Michelle L. McLellan, Melanie Dickie, Stan Boutin, Marcus Becker, Bevan Ernst, Darcy Peel, Kathryn L. Zimmerman, Robert Serrouya

Summary: For wide-ranging species, it is often difficult to implement effective conservation action due to cost or political challenges. To address this, a prioritization approach is needed to focus on areas where conservation efforts are more likely to succeed. Using Southern Mountain Caribou as an example, a simple algorithm is developed to rank subpopulations based on habitat quality and population characteristics, weighted according to expert opinion. Sensitivity analyses are used to measure the impact of criteria variance and expert weighting. This transparent framework allows for discussions on conservation, subpopulation comparisons, and adaptive management. The algorithm can be adapted for other species and used by conservation scientists and managers to prioritize populations for recovery actions.

Light to moderate long-term grazing enhances ecosystem carbon across a broad climatic gradient in northern temperate grasslands

Edward W. Bork, Daniel B. Hewins, Eric G. Lamb, Cameron N. Carlyle, Mark P. Lyseng, Scott X. Chang, Michael J. Alexander, Walter D. Willms, Majid Iravani

Summary: Grasslands globally store significant amounts of carbon, providing valuable ecosystem services. However, the impact of livestock grazing on grassland carbon storage remains uncertain. A study in Alberta, Canada found that while grazing reduced litter mass, total ecosystem carbon was 8.5% higher in grazed grasslands compared to non-grazed grasslands, primarily due to increases in soil organic carbon (SOC) and roots. SOC increased consistently in the 0-15 cm soil layer across all climate conditions, with changes in the 15-30 cm layer related to aridity. The increase in SOC under grazing was indirectly attributed to elevated eudicot biomass and improved graminoid quality, leading to enhanced litter and mulch carbon and ultimately higher SOC densities.

Consistent spatial patterns in microbial taxa of red squirrel gut microbiomes

Alicia Halhed, Lauren Petrullo, Stan Boutin, Ben Dantzer, Andrew McAdam, Martin Wu, Karl Cottenie

Summary: In this study, the gut microbiome samples of red squirrels were analyzed to identify the drivers of microbiome composition. The spatial location of the squirrels was found to be a key contributor to the composition of the gut microbial community. The non-core microbiome showed highly localized spatial patterns, while the core microbiome showed some spatial patterns. The results suggest that environmental transmission plays a role in the spatiotemporal distribution of the red squirrel gut microbiome.
