Field Simulation of Global Change: Transplanting Northern Bog Mesocosms Southward [PDF]

open access: yes, 2010
A large proportion of northern peatlands consists of Sphagnum-dominated ombrotrophic bogs. In these bogs, peat mosses (Sphagnum) and vascular plants occur in an apparent stable equilibrium, thereby sustaining the carbon sink function of the bog ecosystem.

Evasion Differential Games in the Space of Square Summable Sequences

open access: yesGames
In this article, we consider simple-motion pursuit–evasion differential games in the Hilbert space of square summable sequences. We show that when the players have the same dynamic capabilities, evasion is possible under some assumptions about the ...

Changes in vegetation structure and composition of a lowland mire over a sixty‐five‐year interval

open access: yesEcology and Evolution, 2020
Mires are characterized by plant communities of high conservation and societal value, which have experienced a major decline in area in many parts of the world, particularly Europe. Evidence suggests that they may be particularly vulnerable to changes in

Invertebrate communities in a modified isolated raised bog compared to an intact raised bog in New Zealand [PDF]

open access: yesMires and Peat, 2020
The effect of modifying New Zealand’s threatened peat bogs on invertebrate communities is poorly known, despite their susceptibility to disturbance and their ecological significance. Using Malaise traps, we surveyed and compared terrestrial invertebrates

Aniulus Paludicolens, N. SP. (Julida: Paraiulidae), a Bog-Dwelling Milliped [PDF]

open access: yes, 2017
Almost without exception, millipeds require a continuously moist substratum, yet they do not tolerate flooding. Other ecological factors that limit their distribution are subtle and difficult to recognize. Aniulus paludicolens, n.

Forecasting spring frost events in agriculture using machine learning: A case study from southeastern Massachusetts, United States

open access: yesSmart Agricultural Technology
Agricultural crops are frequently exposed to severe frost events in the spring, which can greatly impact yield quantity and quality. To manage frost effectively, early warning systems are often used to forecast potential spring frost in advance of an ...

Vegetation change and the protection of the Csaroda relic mires, Hungary

open access: yesActa Societatis Botanicorum Poloniae, 2014
Study of vegetation change of the protected mires situated near Csaroda and Beregdaróc (the Great Hungarian Plain) are presented. These are the southermost mires with raised bog communities in the plains of Europe.

Multi-environment factors dominate plant community structure and diversity in an ombrotrophic bog: The water level is the main regulating mechanism

open access: yesFrontiers in Environmental Science, 2022
Understanding the relationship between vegetation and the environment is critical to manage bog ecosystems. However, information on how environmental factors influence the species composition and diversity in the ombrotrophic bog of Northeast China is ...

Fire severity is more sensitive to low fuel moisture content on Calluna heathlands than on peat bogs [PDF]

open access: yes, 2018
Moorland habitats dominated by the dwarf shrub Calluna vulgaris provide important ecosystem services. Drought is projected to intensify throughout their range, potentially leading to increased fire severity as moisture is a key control on severity.
