- Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45 degrees N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan Plateau. For all northern peatlands, carbon content in organic matter was estimated at 42 +/- 3% (standard deviation) for Sphagnum peat, 51 +/- 2% for non-Sphagnum peat, and at 49 +/- 2% overall. Dry bulk density averaged 0.12 +/- 0.07 g/cm(3), organic matter bulk density averaged 0.11 +/- 0.05 g/cm(3), and total carbon content in peat averaged 47 +/- 6%. In general, large differences were found between Sphagnum and non-Sphagnum peat types in terms of peat properties. Time-weighted peat carbon accumulation rates averaged 23 +/- 2 (standard error of mean) g C/m(2)/yr during the Holocene on the basis of 151 peat cores from 127 sites, with the highest rates of carbon accumulation (25-28 g C/m(2)/yr) recorded during the early Holocene when the climate was warmer than the present. Furthermore, we estimate the northern peatland carbon and nitrogen pools at 436 and 10 gigatons, respectively. The database is publicly available at https://peatlands.lehigh.edu.

Ecological load and balancing selection in circumboreal barnacles.

- Acorn barnacle adults experience environmental heterogeneity at various spatial scales of their circumboreal habitat, raising the question of how adaptation to high environmental variability is maintained in the face of strong juvenile dispersal and mortality. Here we show that 4% of genes in the barnacle genome experience balancing selection across the entire range of the species. Many of these genes harbor mutations maintained across 2 million years of evolution between the Pacific and Atlantic oceans. These genes are involved in ion regulation, pain reception, and heat tolerance, functions which are essential in highly variable ecosystems. The data also reveal complex population structure within and between basins, driven by the trans-Arctic interchange and the last glaciation. Divergence between Atlantic and Pacific populations is high, foreshadowing the onset of allopatric speciation, and suggesting that balancing selection is strong enough to maintain functional variation for millions of years in the face of complex demography.

Consensus-based guidance for conducting and reporting multi-analyst studies
- 2021
-
Ingår i: eLIFE. - : eLife Sciences Publications. - 2050-084X. ; 10
-
Tidskriftsartikel (refereegranskat)abstract
- Any large dataset can be analyzed in a number of ways, and it is possible that the use of different analysis strategies will lead to different results and conclusions. One way to assess whether the results obtained depend on the analysis strategy chosen is to employ multiple analysts and leave each of them free to follow their own approach. Here, we present consensus-based guidance for conducting and reporting such multi-analyst studies, and we discuss how broader adoption of the multi-analyst approach has the potential to strengthen the robustness of results and conclusions obtained from analyses of datasets in basic and applied research.

A Puzzle About Proportionality
- 2019
-
Ingår i: Res Publica. - : Springer Science and Business Media LLC. - 1572-8692 .- 1356-4765. ; 25:2, s. 133-149

Tidskriftsartikel (refereegranskat)abstract
- The paper addresses a puzzle about the proportionality requirement on self-defense due to L. Alexander. Indirectly the puzzle is also relevant to the proportionality requirement on punishment, insofar as the right to punish is derived from the right to self-defense. Alexander argues that there is no proportionality requirement on either self-defense or punishment, as long as the aggressor/offender has been forewarned of the risk of a disproportional response. To support his position Alexander appeals to some puzzle cases, challenging us to explain why the requirement applies in some of them when it clearly does not in others. The paper responds to his challenge by answering two questions: why does the proportionality requirement exist in the first place, and when does it apply? The paper argues that the requirement holds because of our need to protect our rights from violation, and that it applies to cases where the person defending his rights counts as having imposed a cost on one of the offender’s options. An account is offered of when such cost imposition occurs.

An argument for agent-neutral value
- 2007
-
Ingår i: Ratio. - 0034-0006. ; 20:3, s. 249-263
-
Tidskriftsartikel (refereegranskat)abstract
- This paper argues (a) that to any agent-relative value maker there will correspond an agent-neutral value maker, and the latter explains the former; and (b) that to each agent-relative constitutive ground there corresponds a neutral one, and the latter explains the former. It follows from (b), if not from (a), that agent-neutral value exists if agent-relative value does.

Atomism About Value
- 2004
-
Ingår i: Australasian Journal of Philosophy. - : Informa UK Limited. - 0004-8402 .- 1471-6828. ; 82:2, s. 312-331

Tidskriftsartikel (refereegranskat)abstract
- Atomism is defined as the view that the moral value of any object is ultimately determined by simple features whose contribution to the value of an object is always the same, independently of context. A morally fundamental feature, in a given context, is defined as one whose contribution in that context is determined by no other value fact. Three theses are defended, which together entail atomism: (1) All objects have their moral value ultimately in virtue of morally fundamental features; (2) If a feature is morally fundamental, then its contribution is always the same; (3) Morally fundamental features are simple.

Contractualism, Reciprocity, Compensation
- 2008
-
Ingår i: Journal of Ethics and Social Philosophy. - 1559-3061. ; 2:3
-
Tidskriftsartikel (refereegranskat)abstract
- I argue that it is not possible to give an adequate account, within a Scanlon-style contractualist moral theory of the moral duties to reciprocate benefits one has received from others and to compensate harms one has done to others. The problem, very simply put, is that there is no room within such a theory for the fact that the content of these obligations must be proportionate to the value of the actions that bring them into being in the first place. As a consequence, I point to a wider a moral about contractualism. This is that while that doctrine may provide an adequate account of obligations that we have to others on account simply of their status as persons, it cannot handle obligations that arise as a response to actions that these others, or we ourselves, have performed.

Crime Victims and the Right to Punishment
- 2019
-
Ingår i: Criminal Law and Philosophy. - : Springer Science and Business Media LLC. - 1871-9805 .- 1871-9791. ; 13:1, s. 63-81
-
Tidskriftsartikel (refereegranskat)abstract
- In this paper, I consider the question of whether crime victims can be said to have a moral right to see their victimizers punished (a “right to punishment”) that could explain why they often feel wronged or cheated when the state fails to punish offenders (or even to make such conduct punishable). In the first part, I explain what I mean by a “right to punishment” and what it is for such a right to “explain” the frustrated crime victim’s reaction. In the second part, I distinguish such a right from a Lockean-style right to punish, which is also shown incapable of providing the needed explanation. In the third part I argue that it is difficult to identify any benefit such that the right to punishment could plausibly be understood as a right to that benefit. I discuss two main candidates here: (i) the vaguely Hegelian idea that punishment is itself some sort of restitution for the wrong done to the victim; and (ii) the idea, due to Victor Tadros, that punishment is a form of compensation for wrongdoing by contributing indirectly to protecting victims from future harm. In the final section, I suggest instead that the frustrated crime victim’s reaction, when justified, is best explained, not by the violation of any right to punishment, but rather by the state’s failure to treat the victim as an equal.
