Understanding how landscape elements contribute to functional connectivity in a multispecies context is important to inform city planning. We compared the connectivity of urban forest habitats for three vertebrate species with contrasting dispersal modes: the Siberian flying squirrel ( Pteromys volans ), the common lizard ( Zootoca vivipara ) and European crested tit ( Lophophanes cristatus ). We used Graphab and Circuitscape,...
Vascular repair and regeneration are critical for tissue homeostasis. Endothelial colony forming cells (ECFCs) are vessel-resident progenitors with vasoreparative capacity and they offer an important avenue for allogeneic cytotherapy to achieve perfusion of ischemic tissues. Endothelial Protein C Receptor (EPCR) has been proposed as a marker for vascular endothelial stem cells, but its precise role in ECFC biology remains unkn...
Balancing landscape values and tourism choices: Integrating participatory mapping and the IPBES Values TypologyNARA Subscribed
The United Nations Educational, Scientific and Cultural Organization (UNESCO) Biosphere Reserves aim to balance nature and human coexistence, but increasing tourism challenges landscape management. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) stresses the importance of understanding stakeholder values for effective management of natural spaces through a typology of intrinsic, ins...
The study of the stratosphere-troposphere interaction is important as it can contribute to boosting predictability in the subseasonal-to-seasonal timescale, particularly regarding extremes. This manuscript investigates the relationship between the stratospheric polar vortex and its sudden stratospheric warming and the troposphere in regard to the reflective and absorptive states of the vortex. We explore the eddy heat flux in...
Critical thermal maximum (CT max ) is widely used to measure upper thermal tolerance in fish but is rarely examined in embryos. Upper thermal limits generally depend on an individual's thermal history, which molds plasticity. We examined how thermal acclimation affects thermal tolerance of brook trout ( Salvelinus fontinalis ) embryos using a novel method to assess CT max in embryos incubated under three thermal regimes. Warm...
Weight-gain independent effect of mirtazapine on fasting plasma lipids in healthy menNARA Subscribed
Treatment with mirtazapine, a widely prescribed antidepressant, has been linked to weight gain and dyslipidemia. Whether dyslipidemia occurs secondary to increased appetite due to antidepressant treatment, or due to direct pharmacological effects of mirtazapine is unknown. The aim of this analysis is to complement our previously published results of the effect of mirtazapine on metabolism and energy substrate partitioning from...
Global assessment of the biodiversity safeguards of development banks that finance infrastructureNARA Subscribed
Infrastructure development is a major driver of biodiversity loss globally. With upward of US$2.5 trillion in annual investments in infrastructure, the financial sector indirectly drives this biodiversity loss. At the same time, biodiversity safeguards (project‐level biodiversity impact mitigation requirements) of infrastructure financiers can help limit this damage. The coverage and harmonization of biodiversity safeguards ar...
Smallholder oil palm plantation sustainability assessment using multi-criteria analysis and unmanned aerial vehiclesNARA Subscribed
Oil palm agriculture has caused extensive land cover and land use changes that have adversely affected tropical landscapes and ecosystems. However, monitoring and assessment of oil palm plantation areas to support sustainable management is costly and labour-intensive. This study used an unmanned aerial vehicles (UAV) to map smallholder farms and applied multi-criteria analysis to data generated from orthomosaics, to provide a...
Spatial variability in carbon dioxide (CO 2 ) and oxygen (O 2 ) was assessed within an Indigenous Hawaiian fishpond undergoing active ecosystem restoration. The brackish, tidal fishpond is located within Kāne‘ohe Bay, Hawai‘i. Following a year of monthly discrete sampling, a significant shift in DIC and percent O 2 saturation was observed along the North-South axis within the pond. The south end of the pond was higher in DIC (...
Large‐scale reforestation can increase water yield and reduce drought risk for water‐insecure regions in the Asia‐PacificNARA Subscribed
Large‐scale reforestation can potentially bring both benefits and risks to the water cycle, which needs to be better quantified under future climates to inform reforestation decisions. We identified 477 water‐insecure basins worldwide accounting for 44.6% (380.2 Mha) of the global reforestation potential. As many of these basins are in the Asia‐Pacific, we used regional coupled land‐climate modeling for the period 2041–2070 to...
