Reintroduction of Fish and Wildlife Populationsprovides a practical step-by-step guide to successfully planning, implementing, and evaluating the reestablishment of animal populations in former ...habitats or their introduction in new environments. In each chapter, experts in reintroduction biology outline a comprehensive synthesis of core concepts, issues, techniques, and perspectives. This manual and reference supports scientists and managers from fisheries and wildlife professions as they plan reintroductions, initiate releases of individuals, and manage restored populations over time. Covering a broad range of taxonomic groups, ecosystems, and global regions, this edited volume is an essential guide for academics, students, and professionals in natural resource management.
Back from the Collapse is a clarion call for restoring one of North America’s most underappreciated and overlooked ecosystems: the grasslands of the Great Plains. This region has been called ...America’s Serengeti in recognition of its historically extraordinary abundance of wildlife. Since Euro-American colonization, however, populations of at least twenty-four species of Great Plains wildlife have collapsed—from pallid sturgeon and burrowing owls to all major mammals, including bison and grizzly bears. In response to this incalculable loss, Curtis H. Freese and other conservationists founded American Prairie, a nonprofit organization with the mission of supporting the region’s native wildlife by establishing a 3.2-million-acre reserve on the plains of eastern Montana, one of the most intact and highest-priority areas for biodiversity conservation in the Great Plains. In Back from the Collapse Freese explores the evolutionary history of the region’s ecosystem over millions of years, as it transitioned from subtropical forests to the edge of an ice sheet to today’s prairies. He details the eventual species collapse and American Prairie’s work to restore the habitat and wildlife, efforts described by National Geographic as “one of the most ambitious conservation projects in American history.”
The efficacy of a low fermentable oligo-, di-, monosaccharides and polyols (FODMAP) diet in irritable bowel syndrome (IBS) is well established. After the elimination period, a reintroduction phase ...aims to identify triggers. We studied the impact of a blinded reintroduction using FODMAP powders to objectively identify triggers and evaluated the effect on symptoms, quality of life, and psychosocial comorbidities.
Responders to a 6-week low FODMAP diet, defined by a drop in IBS symptom severity score (IBS-SSS) compared with baseline, entered a 9-week blinded randomized reintroduction phase with 6 FODMAP powders (fructans, fructose, galacto-oligosaccharides, lactose, mannitol, sorbitol) or control (glucose). A rise in IBS-SSS (≥50 points) defined a FODMAP trigger. Patients completed daily symptom diaries and questionnaires for quality of life and psychosocial comorbidities.
In 117 recruited patients with IBS, IBS-SSS improved significantly after the elimination period compared with baseline (150 ± 116 vs 301 ± 97, P < .0001, 80% responders). Symptom recurrence was triggered in 85% of the FODMAP powders, by an average of 2.5 ± 2 FODMAPs/patient. The most prevalent triggers were fructans (56%) and mannitol (54%), followed by galacto-oligosaccharides, lactose, fructose, sorbitol, and glucose (respectively 35%, 28%, 27%, 23%, and 26%) with a significant increase in abdominal pain at day 1 for sorbitol/mannitol, day 2 for fructans/galacto-oligosaccharides, and day 3 for lactose.
We confirmed the significant benefit of the low FODMAP diet in tertiary-care IBS. A blinded reintroduction revealed a personalized pattern of symptom recurrence, with fructans and mannitol as the most prevalent, and allows the most objective identification of individual FODMAP triggers. Ethical commission University hospital of Leuven reference number: s63629; Clinicaltrials.gov number: NCT04373304.
We studied the impact of a blinded reintroduction using fermentable oligo-, di-, monosaccharides and polyols (FODMAP) powders to identify triggering FODMAPs. It allows the most objective identification of individual triggers and would optimize clinical practice.
Understanding factors that influence real‐world public conservation behaviors is critical for developing successful conservation policies and management actions. Citizens of Colorado, USA recently ...passed a ballot initiative to restore the gray wolf to its former range within the state. The >3 million votes offer an unprecedented opportunity to test factors that influenced decisions to support or oppose this conservation action. We created spatial linear regression models to assess the relationship between support for wolf restoration and (1) the presidential vote, (2) distance to conservation intervention (i.e., proposed wolf reintroduction and existing wolves), and measures of (3) livelihood and (4) demographics using precinct‐level data. Our results demonstrate the strong relationship between support for wolf restoration and political support for the Democratic candidate for president in the 2020 election, and highlight how other factors, including increased age, participation in elk hunting, and proximity to the reintroduction region were associated with less support. Our findings underscore the critical role of politicization on public conservation action and the need to develop outreach and engagement strategies to mitigate polarization.
