Demographic measures of Liatris ohlingerae (Asteraceae) in 20 populations across multiple habitats and time-since-fire intervals in south central Florida from 1997-2017
Demographic data were collected on 2,858 tagged individually marked plants annually from 1997 to 2017 in 20 populations across three sites on the southern end of the Lake Wales Ridge in south central Florida, USA. Our goal was to understand demographic responses including recruitment, survival, reproduction and mortality of individuals across populations, habitat types and fire-return-intervals. Habitats include rosemary scrub, scrubby flatwoods and human created sandy roadsides. Populations spanned three sites including Archbold Biological Station (18 populations), Florida Forest Service Arbuckle Tract of the Lake Wales Ridge State Forest (1 population), and Florida Fish and Wildlife Conservation Commission Gould Road property (1 population). Annual demographic measures include survival (including plant dormancy), stage, measures of size, reproductive effort and herbivory. Plots were surveyed annually during flowering in August for previously marked plants and searched for newly recruited putative seedlings or previously missed larger adults. This landscape is managed with periodic prescribed fire impacting some populations with additional post-burn censuses completed after the burn. In addition, damage following three hurricanes in 2004 were recorded. Plants were followed through their lifecycle and after four years of no aboveground growth, plants were assumed dead and tags removed from the field.
Demographic measures of Hypericum cumulicola (Hypericaceae) in 15 populations in Florida Rosemary Scrub patches with different time-since-fire, at Archbold Biological Station, Highlands County, Florida from 1994-2015
We collected demographic data comprising 38,313 unique observations from a sample of 10,910 individuals of H. cumulicola, from 15 independent Florida rosemary scrub patches with different time-since-fire at Archbold Biological Station, Highlands County, Florida. Plants were censused during their peak of reproduction annually in July and August between 1994 and 2015.
Data from: Upland Sandpipers select for later time since fire and experience high nest survival in grasslands managed with patch-burn grazing
<p>Upland Sandpipers (<em>Bartramia longicauda</em>) are a grassland obligate shorebird that nests in dense vegetation structure near recently disturbed areas and could benefit from management practices that promote heterogenous vegetation structure. Although, Upland Sandpipers primary breeding range is generally managed for livestock production using traditional practices that lack patchy disturbances to facilitate higher levels of structural heterogeneity. Patch-burn grazing (PBG) could be an alternative management practice for Upland Sandpiper conservation for its ability to create areas of dense vegetation structure near recently disturbed areas. However, limited information is available regarding nest production of Upland Sandpipers within a PBG framework. To assess the compatibility of PBG with Upland Sandpiper conservation, we estimated nest site selection and survival of Upland Sandpiper nests on private lands managed with PBG in the unglaciated plains region of North Dakota. We located 59 nests from 2017–2020. Upland Sandpipers avoided 1 year since fire (YSF) patches and selected for 2 and 3 YSF patches for nest sites. Additionally, nest site selection decreased with increased bare ground and at intermediate distances to the nearest Upland Sandpiper nest. Upland Sandpipers experienced high overall nest survival during the study with 51 of 59 nests successfully hatching, which limited our ability to make inferences between daily survival rates and variables of interest. Our findings suggest that PBG can provide suitable nesting cover for Upland Sandpipers in later YSF patches despite annual prescribed fire and livestock grazing during the nesting season. PBG seems a suitable grassland management strategy that should be included in conservation planning within Upland Sandpiper's breeding distribution.</p>
Data for: Fire season and time since fire determine AM fungal trait responses to fire management
<p><strong>Rationale:</strong> AM fungi are common mutualists in grassland and savanna systems that are adapted to recurrent fire disturbance. This long-term adaptation to fire means that AM fungi display disturbance associated traits which are useful for understanding environmental and temporal effects on AM fungal community assembly. </p> <p><strong>Methods:</strong> In this work, we evaluated how fire driven ecological selection on AM fungal spore traits varies with fire season (Fall vs. Spring) and time since fire. We tested this by analyzing AM fungal spore traits (e.g., colorimetric, sporulation, and size) from a fire regime experiment. </p> <p><span><span> </span></span><strong>Key results:</strong> Immediately following Fall and Spring fires, spore pigmentation darkened; however, this did not mediate the observed differences between Fall burned and no burn communities. Six months after Fall fires, spores in burned plots were lower in volume, produced less color rich pigment, and had higher sporulation rates, and these differences in spore traits were associated with shifts in AM fungal spore communities.</p> <p><strong>Main conclusion:</strong> This shows that AM fungal responses to fire vary based on season (stronger effects in the Fall) and with time since fire. Variation in AM fungal responses to fire time may reflect greater exposure to fire in Fall, when sporulation is highest.</p>
Fire recurrence and time since last fire interact to determine the supply of multiple ecosystem services by Mediterranean forests
<p>Wildfires shape the composition and functioning of Mediterranean ecosystems, but we do not know how these ecosystems respond to both the higher fire recurrence and shorter recovery times expected for future climatic scenarios. We sampled 29 plots with different fire recurrences (from 0 to 4 fires over the past decades) and time since the last fire (up to 35 years; hereafter TSLF) in Southeast Spain, to assess the effect of fire recurrence and TSLF on 25 ecosystem attributes, five related ecosystem services (biodiversity conservation, carbon sequestration, disturbance regulation, food production, and supporting services), plus the synergies and trade-offs between them. High fire recurrence (number of fires) and TSLF interacted to determine ecosystem services but did not affect the synergies and trade-offs between them. Fire recurrence reduced many ecosystem functions and ecosystem multifunctionality. However, this effect dampened, and even became positive, for biodiversity conservation and food production services provided enough (> 20 years) time to recover. The combined effects of fire recurrence and TSLF, however, reduced carbon sequestration and had no overall effects on supporting services. Disturbance regulation, in turn, diminished drastically with the first fire, with no effect of further fires or their interaction with TSLF. Our results show which ecosystem services will suffer more from an increase in fire recurrence, and where restoration and management efforts should focus to maximize the provision of those services more demanded by stakeholders.</p>
