Monthly litterfall, monthly tree band, and annual tree growth of a South Carolina coastal wetland forest
In the southern United States, forested wetlands are of special interest because of the extent of these forests. One of the problems in developing management practices for these areas is the difficulty in adequately describing productivity relations and predicting how the structure and function of these communities might be affected by natural or anthropogenic disturbances. Community response to environmental change often occurs over a period of years, and the majority of reported studies are for 1–3 years in duration. This study was initiated in an attempt to examine long-term changes in forest systems in response to drought, flooding, hurricanes, and climate change. This study documents long-term changes in structure, composition, and growth along a gradient of high water table forested sites of an ancient beach ridge landscape in coastal South Carolina. Permanent study plots (20-m x 25-m) were established across a moisture gradient (Xeric, Mesic, and Hydric – 5 plots in each) within a longleaf pine-swamp blackgum forest system on the southern end of the Waccamaw Neck area of Georgetown County, SC in January 2000. Litterfall was measured monthly using five 0.25 m2 litter traps in each plot beginning in February to December 2018. Monthly circumference change was recorded on a subset of trees within each plot using stainless steel dendrometer bands. Diameter of all trees greater than or equal to 10 cm diameter at breast height in each plot was recorded annually at the end of the growing season.
Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean
<p></p> <p class="MsoNormal"><span>The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters. This may cause freshwater browning, as more degraded plant-litter ends up as chromophoric (coloured) dissolved organic matter. Although most freshwater ultimately drains to coastal waters, the link between freshwater browning and coastal water darkening is poorly understood. Here, we explore this relationship through a combination of centennial records of forest and coastal water clarity, contemporary optical measurements in lakes and coastal waters, as well as an ocean drift model. We suggest a link between forest cover in Northern Europe and coastal water clarity in the Baltic, Kattegat and Skagerrak Sea and show how brown coloured freshwater from Northern European catchments can dictate coastal water clarity across thousands of kilometres, from the Baltic lakes to the Barents Sea.</span></p>

Data from: The distribution of tree biomass carbon within the pacific coastal temperate rainforest, a disproportionally carbon dense forest
<p>Spatially explicit global estimates of forest carbon storage are typically coarsely scaled. While useful, these estimates do not account for the variability and distribution of carbon at management scales. We asked how climate, topography, and disturbance regimes interact across and within geopolitical boundaries to influence tree biomass carbon, using the perhumid region of the Pacific Coastal Temperate Rainforest, an infrequently disturbed carbon dense landscape, as a test case. We leveraged permanent sample plots in southeast Alaska and coastal British Columbia and used multiple quantile regression forests and generalized linear models to estimate tree biomass carbon stocks and the effects of topography, climate, and disturbance regimes. We estimate tree biomass carbon stocks are either 211 (SD = 163) Mg C ha<sup>-1</sup> or 218 (SD = 169) Mg C ha<sup>-1</sup>. Natural disturbance regimes had no correlation with tree biomass but logging decreased tree biomass carbon and the effect diminished with increasing time since logging. Despite accounting for 0.3% of global forest area, this forest stores between 0.63% - 1.07% of global aboveground forest carbon as aboveground live tree biomass. The disparate impact of logging and natural disturbance regimes on tree biomass carbon suggests a mismatch between current forest management and disturbance history.</p>

Disturbed Forest on Sandy Coastal Plain, Saquarema/RJ - Datasets and Phytosociological analyses
<p>Os dados brutos foram coletados em 2019 por Bárbara de Pinho Agapito, Cyl Farney Catarino de Sá & Dorothy Sue Dunn de Araujo em área perturbada de Floresta de Restinga em Saquarema/RJ. Um grande distúrbio ocorreu entre 1965/1970 com corte e queima da floresta para abertura de pastagem e cultivos temporários. O solo arenoso, o fogo recorrente e a disseminação de gramíneas invasoras agressivas tem retardado a regeneração da floresta cuja matriz é adjacente. Parcelas de 5 x 5 m foram instaladas nessa área perturbada para análise da regeneração avaliando ocorrência, abundância e persistência das espécies lenhosas. Foram medidos todos os indivíduos com DAS ≥ 0,1 cm , assim como suas alturas foram tomadas. A análise fitossociológica também está disponível com todos os parâmetros absolutos e relativos, calculados através do Excel. </p>

Fijian sea krait behavior relates to fine‐scale environmental heterogeneity in old‐growth coastal forest: The importance of integrated land–sea management for protecting amphibious animals
<p><span>Here the data for "Fijian sea krait behaviour relates to fine-scale environmental heterogeneity in old growth forest: the importance of integrated land-sea management for protecting amphibious animals" by</span><span> Lowe, C., Keppel, G., Waqa, K., Peters, S., Fisher, R.N., Scanlon, A., Osborne-Naikatini, T, and Thomas-Moko, N </span><span> is provided. This article investigates the habitat of </span>Yellow Lipped Sea Kraits, <em>Laticauda</em> <em>colubrina</em>, in the terrestrial realm on Leluvia Island, a small, topographically flat atoll in Fiji with coastal forest. The investigation uses concurrent microclimate measurements and behaviour surveys, as well as vegetation surveys, and the data collected for these analyses are provided here. Microclimates were significantly related to canopy cover, leaf litter depth, and distance from the high-water mark (HWM). Sea kraits were almost exclusively observed in coastal forest within 30 m of the HWM. Sloughing of skins only occurred within crevices of mature or dying trees. Resting <em>L</em>. <em>colubrina</em> were significantly more likely to occur at locations with higher mean diurnal temperatures, lower leaf litter depths, and shorter distances from the HWM. On Leleuvia, behaviour of <em>L</em>. <em>colubrina</em> therefore relates to environmental heterogeneity created by old-growth coastal forests, particularly canopy cover and crevices in mature and dead tree trunks. The importance of healthy coastal habitats, both terrestrial and marine, for <em>L</em>. <em>colubrina</em> suggests it could be a good flagship species for advocating integrated land-sea management. Furthermore, our study highlights the importance of coastal forests and topographically flat atolls for biodiversity conservation. Effective conservation management of amphibious species that utilise land- and seascapes is therefore likely to require a holistic approach that incorporates connectivity among ecosystems and environmental heterogeneity at all relevant scales.</p>
