Critique and transformation: On the hypothetical nature of ecosystem service value and its neo-Marxist, liberal and pragmatist criticisms
Ecosystem service valuation (ESV) attempts to transform the opposition of human economic necessity and ecological conservation by valuing the latter in terms of the services rendered by the former. However, despite a number of ESV-inspired sustainability initiatives since the 1990s, global ecological degradation continues to accelerate. This suggests that ESV has fallen far short of its goals of sustainable social transformation—a failure which has generated considerable criticism. This paper reviews three prominent lines of ESV criticism: 1) the neo-Marxist criticism, which emphasizes the “fictitious” character of ecosystem commodities; 2) the liberal criticism through Friedrich Hayek\u27s concept “scientistic objectivism”; and 3) the pragmatist criticism of “value monism”. Although each form of criticism provides insight into the limitations of ESV, all share ESV\u27s inability to discern what kind of social transformation is possible. Unable to provide an account of their own immersion in social and historical context, these approaches operate in the hypothetical. In light of these shortcomings, this paper advances a critical theory approach, which we contend provides conceptual tools uniquely well-suited to more adequately address the question of social transformation
Moishe Postone and the Critique of Traditional Marxism: Helplessness and the Present Moment of the Great Acceleration
This chapter situates Moishe Postone\u27s critique of traditional Marxism in relation to the present moment of the Great Acceleration. We engage a close reading of Postone reinterpretation of Marx\u27s mature theory of capital with specific focus on the linkage between economic growth and ecological degradation, and how this linkage is necessary connected to social domination in modern capitalist society. Postone\u27s Marxian theory is significant because, as we demonstrate, it allows one to grasp societally induced environmental degradation following WWII in a critical and reflexive manner. The chapter concludes by discussing the growing sense of helplessness that defines the present moment of the Great Acceleration
Integrative Genomics Reveals the Genetics and Evolution of the Honey Bee’s Social Immune System
Social organisms combat pathogens through individual innate immune responses or through social immunity—behaviors among individuals that limit pathogen transmission within groups. Although we have a relatively detailed understanding of the genetics and evolution of the innate immune system of animals, we know little about social immunity. Addressing this knowledge gap is crucial for understanding how life-history traits influence immunity, and identifying if trade-offs exist between innate and social immunity. Hygienic behavior in the Western honey bee, Apis mellifera, provides an excellent model for investigating the genetics and evolution of social immunity in animals. This heritable, colony-level behavior is performed by nurse bees when they detect and remove infected or dead brood from the colony. We sequenced 125 haploid genomes from two artificially selected highly hygienic populations and a baseline unselected population. Genomic contrasts allowed us to identify a minimum of 73 genes tentatively associated with hygienic behavior. Many genes were within previously discovered QTLs associated with hygienic behavior and were predictive of hygienic behavior within the unselected population. These genes were often involved in neuronal development and sensory perception in solitary insects. We found that genes associated with hygienic behavior have evidence of positive selection within honey bees (Apis), supporting the hypothesis that social immunity contributes to fitness. Our results indicate that genes influencing developmental neurobiology and behavior in solitary insects may have been co-opted to give rise to a novel and adaptive social immune phenotype in honey bees.York University Librarie
Oregon Bee Atlas: native bee findings from 2018
The Oregon Bee Atlas is a new volunteer-led effort to characterize the bee fauna of Oregon State by collecting, preparing, and databasing native bee species and capturing plant host records. In 2018, volunteers collected 11,044 bee specimens across 33 Oregon counties, representing 179 unique bee species, and 32 unique bee genera. Specimens were collected from a total of 310 unique flowering plant genera, resulting in one of the largest state-level databases of bee-host plant interactions. Volunteers produced valuable occurrence records for species poorly known for the State, and species of conservation concern. The 2018 efforts constitute a proof-of-concept of a specimen-focused volunteer native bee survey
Designing Dual-Purpose Management Strategies for Sheep Production and Pollinators in Dryland Pastures
Development of novel grazing management practicesfor both livestock production and pollinator health is becoming increasingly crucial in pasture-based farming systems. The effect of pasture type and spring closing dates on lamb liveweight gain, pasture production, botanical composition, bloom density and bee visitation was monitored over 2 years at the Oregon State University in Corvallis. Total annual dry matter yield (DMY) of diverse pastures in 2020/2021 was 8.8 t DM ha-1 and this was greater (P-1) and legume pastures (6.6 t DM ha-1). In successive years, lambs grew faster in legume pastures (287, 215 g per head d-1) than diverse (207, 151 g per head d-1) and simple pastures (204, 132 g per head d-1 ). However, spring liveweight production (kg ha1 day-1) from pastures did not differ due to lower stocking density of legume pastures as compared to other two pasture mixtures. Bloom density (flower/m2) and bee visitation (bees/min-1 m2) were 25 and 40 times greater, respectively, with legume than simple pastures. Bloom density for diverse pastures were also relatively low, being 5.7 times lower than the legume pastures. Our findings indicated that diversification of pastures with forbs greatly increased pasture productivity, while legume pastures provided the highest pollinator benefit without penalizing lamb liveweight production in spring
Expression of heat-shock protein genes in Apis mellifera meda(Hymenoptera: Apidae) after exposure to monoterpenoids and infestation by Varroa destructor mites (Acari: Varroidae)
Heat shock proteins (hsps) protect proteins in eukaryotic cells from damage. Expression of hsps in insects subject to different environmental stimuli is poorly characterized. Here, levels of expression of the hsps genes (hsp40, hsp70, and hsp90) were recorded in Apis mellifera Linnaeus (Hymenoptera: Apidae) workers after exposure to sublethal concentrations of thymol, eucalyptol, α-pinene, trans-anethole, diallyl disulfide and infestation with Varroa mites. Our results show a dose-dependent up-regulation in the levels of all the hsps tested after the bees were treated with thymol, eucalyptol and α-pinene. Although these up-regulated expressions were statistically significant for hsp70 and hsp90 when the bees were treated with thymol and eucalyptol, they were not significant when treated with α-pinene. In addition, significant down-regulated expressions of the hsp genes were recorded in the diallyl disulfide treatment. The transcriptions of all the hsps tested were significantly down-regulated when pupae were infested with different numbers (0-5) of Varroa mites. Thus, it is likely that hsps can be used as biomarkers of survival when honey bees are under toxic and pathogenic stress, but this needs to be confirmed
Oregon Bee Atlas: Wild bee findings from 2019
The Oregon Bee Atlas is a new volunteer-led effort to characterize the bee fauna of Oregon State by collecting, preparing and databasing specimens of wild bee species and their plant host records. In 2019 volunteers submitted 25,022 bee specimens across all Oregon counties, representing 224 unique bee species and 45 unique bee genera. Specimens were collected from a total of 352 unique flowering plant genera, resulting in the largest contemporary state-level database of bee-host plant interactions. Volunteers produced valuable occurrence records for species poorly known for the state, and species of conservation concern. The 2019 data builds on the efforts of 2018 in demonstrating the power of a specimen-focused, volunteer wild bee survey
