"The sound comes from a meadow in the Sierra Nevada Mountains in California. The meadow is at an elevation of 2400 meters near a mountain named Olancha Peak, which is 3700 meters in altitude. Ihave a group of friends with which Ibackpack (trek) into the mountains. Our goal was to spend some time in the mountains and hike to the top of Olancha Peak (…) By the time we reached the meadow, we were in a forest and there was still snow on the ground in some places. We took the trip in June of 2006. The Sierra Nevada Mountains are a large mountain range. Much of the range is protected by national parks or preserved areas we call 'wilderness areas' (…) Ihave been backpacking for nearly 40 years and Iwill hopefully continue with this challenging activity for 40 years more! Many of my friends are much younger than Iam and it gives me much satisfaction to be able to have as much or more stamina for this activity than they have! When we are on these trips, we hike up peaks, catch fish, drink some whiskey around campfires and enjoy our time in the beautiful solitude. My memories of this trip were of the steep, hot hike from the desert to the cool meadow; the overall beauty of the nature, the absolute solitude of our campsite near the meadow; the strenuous hike to the top of Olancha Peak; the camaraderie of my friends; and, of course the sound of the frogs in the meadow. The frog sounds were astounding to me and Iwould listen in awe of the creature's instinctual desire to reproduce and continue the existence of their kind. Surely there were different species in the meadow for some of the frog sounds were different than others. The sounds only occurred after the Sun went down for the evening. Istood next to the creek in the meadow and recorded the sounds using my digital camera." [Peter/plentz1960]16 in Collecting Sounds. Online Sharing of Field Recordings as Cultural Practice

Dataset of: Community perspectives on the prospect of lion (Panthera leo) reintroduction to Comoé National Park, Côte d'Ivoire (West Africa)
<p><span>The civil war in Côte d'Ivoire led to a hike in human disturbances and the extirpation of the African lion (<em>Panthera</em> <em>leo</em>) from the Comoé National Park (CNP). After the war, many efforts have been made to restore this ecosystem and management is considering the reintroduction of lions. In participatory management with people at the center of conservation, there is a need to discuss with communities the initiatives affecting their livelihoods. We assessed the acceptance of lion reintroduction by the local communities; through semi-structured questionnaires to 307 volunteer participants in surrounding 23 villages. Most respondents had knowledge of lions from CNP (93%, n=286). A generalized linear model (GLM) revealed that </span><span>sex, profession, perceived benefits and risks, and an appreciation of the current management system are the main significant determinants for the acceptance of lion reintroduction in CNP.</span><span> A large majority (73%, n=223) were in favor of the lion reintroduction with significant variance among socio-professional categories. The majority of respondents (81%, n=250) acknowledged having coexisted with lions, with previous lion conflicts reported by 20% (n = 61), and a willingness to coexist in the future by 74% (n = 227). More than 84% (n=260) believed that there would be benefits associated with lion reintroduction to CNP and 53% (n=162) believed that the potential benefits would be greater than the possible risks associated with lions. Most respondents (88%; n=270) confirmed the possibility of taking precautions to prevent future lion attacks. While only 42% (n = 129) of respondents felt that current management was participatory, most of them felt that it was acceptable (83%; n = 254). </span><span>Our data shows a large degree of lion support, positive perceptions, and willingness to coexist with lions in the future. These results form part of a fundamental step in the direction for ethical reintroduction, as described by the IUCN reintroduction specialist group</span><span>. </span><span>We recommend the improvement of the involvement of indigenous communities in potential reintroduction of lions, especially the pastoralists, and the sharing of any associated benefits.</span></p>

Postfire tree regeneration in Glacier National Park
Recent increases in fire frequency and severity across the western US are triggering abrupt changes in ecosystem structure and composition, especially in lower montane forests, but consequences of fire-regime change for mesic, mixed-conifer forests remain uncertain. Glacier National Park (Montana, USA) is characterized by a complex mosaic of species typical of Rocky Mountain, Pacific Northwest and boreal floras, creating opportunities for species composition to shift as species respond individualistically to environmental change. We quantified prefire and postfire stem density and composition in a recent anomalously short-interval fire (15 yrs) and historically typical long-interval fire (88-282+ yrs) to answer two questions: (1) How do the structure and composition of tree regeneration differ after long- and short-interval fires that burned in close proximity? (2) What drivers explain differences in postfire regeneration densities among species? We additionally compared understory cover in each fire to anticipate consequences of contemporary fire for the whole plant community. Mean postfire tree seedling density was 45 times higher after the long- than short-interval fire, and many stands in the short-interval fire lacked any tree regeneration. Postfire tree seedling densities were above prefire stem densities in the long-interval fire but well below in the short-interval fire. After both fires, fire-avoiding conifers (e.g., Picea engelmannii, Abies lasiocarpa) were generally replaced by fire-tolerating or fire-embracing species (e.g., Larix occidentalis, Pinus contorta var. latifolia). Some stands remained dominated by fire-sensitive conifers after long-interval fire but never after short-interval fire. Seedlings of Thuja plicata and Tsuga heterophylla were present after the long-interval fire but absent before and after the short-interval fire, despite historically occupying both burned areas. For all species, seedling density increased with indicators of proxima
Morphometric measures from birds in the Serra do Cipó National Park (1999-2009), Minas Gerais, Brazil
Morphometric data of 111 bird species, and 1732 individuals, captured in mist nets over a period of 10 years, from February 1999 to October 2009, were presented. The captures were made in the locality of 'Lagoa das Capivaras', inserted in the Serra do Cipó National Park (-19.346023, -43.609918). The capture with misty nets consisted of the use of bird capture nets of 12, nine, and six meters in length by three meters in height. The captured birds were identified at the species level, with the aid of guides and identification keys, and marked with numbered metal rings provided by CEMAVE - Centro de Pesquisas para Conservação das Aves Silvestres. Capture sessions were carried out by placing two to 20 nets in different locations throughout the area, remaining open throughout the morning, for several days and months over the years mentioned. All individuals were listed following the nomenclature and classification suggested by the Brazilian Committee for Ornithological Records. Biometric data of each individual were measured regarding body mass, wing length tarsus, the beak (height, length, and width), occiput (occipital region to nasofrontal suture), and total length. For this, calipers, rulers, and dynamometers with a precision of 0.1 g were used for small birds (such as those of the family Trochilidae), 1 g for medium birds, and 10 g for birds over 100 g. In addition to the age classification: juvenile (J), adult (A), and indeterminate (I); and sex: male (M), female (F), and indeterminate (I). Bird's morphometric is important data to support a variety of studies, especially those of taxonomy, physiology, ecology, and evolutionary implications of a particular species.
Rocky Mountain National Park bulk inorganic N deposition in close proximity to roads, summer 2021
Vehicles are an important source for N deposition that may negatively impact roadside ecosystems. While elevated roadside N deposition has been found in many locations, it is not yet known if vehicle emissions cause measurable increases of N deposition in complex, mountainous terrain adjacent to roads. To address this, this study investigated the effect of vehicle N emissions on throughfall (through trees) and open N deposition in a high traffic corridor in mountainous terrain of Rocky Mountain National Park, Colorado, USA. We measured bulk (wet + dry) atmospheric N deposition in throughfall and open samplers on transects of 750 (throughfall) and 225 (open) m moving away from the road using ion exchange resin (IER) collectors. This dataset contains inorganic nitrogen deposition data from this study.
Postfire aspen presence, persistence and size in subalpine forests of Yellowstone National Park, USA. 1996 - 2014
Determining how ecological filters (e.g., climate, soils, biotic interactions) influence where species succeed in heterogeneous landscapes is challenging for long-lived species (e.g., trees), because filters can vary over space and change slowly through time. Stand-replacing wildfires create opportunities for establishment of tree-species cohorts and can catalyze rapid shifts in where species occur, facilitating unique opportunities for long-term study. We quantified effects of multiple ecological filters on a colonizing cohort of aspen (Populus tremuloides) that established from seed throughout burned lodgepole pine (Pinus contorta var. latifolia) forests after the 1988 fires in Yellowstone National Park (Wyoming, USA) to ask: (1) How have aspen presence, density, and size varied across the postfire landscape, and what filters explain these spatial and temporal patterns? (2) How does aspen above-and belowground biomass vary with postfire lodgepole-pine density? Aspen persisted to postfire year 25 in 58% of the plots in which aspen were present in postfire year 11 (n = 45), and mean stem density declined from 522 to 310 stems ha-1. Mean aspen height doubled (from 29 to 59 cm) over this period. Ecological filters related to climate, competition, herbivory, and soils all differentially affected aspen presence, persistence, and size. Growing season temperature, inter-specific competition, and herbivory also changed through time, altering their effects on the colonizing cohort, and shifting where on the landscape aspen persistence and growth were ultimately favored. Eleven years postfire, aspen were favored at warmer, low elevations; ungulate browsing strongly constrained aspen heights; and competition was unimportant. By 25-years postfire, temperatures warmed nearly 1 C, and aspen were more likely to persist at cooler, high elevations. Browsing pressure declined, as ungulate populations decreased during this time, but aspen height and basal diameters were constrained b
Can wildland fire management alter 21st-century subalpine fire and forests in Grand Teton National Park, Wyoming, USA
In subalpine forests of the western United States that historically experienced infrequent, high-severity fire, whether fire management can shape 21st-century fire regimes and forest dynamics to meet natural resource objectives is not known. Managed wildfire use (i.e., allowing lightning-ignited fires to burn when risk is low instead of suppressing them) is one approach for maintaining natural fire regimes and fostering mosaics of forest structure, stand age, and tree-species composition, while protecting people and property. However, little guidance exists for where and when this strategy may be effective with climate change. We simulated most of the contiguous forest in Grand Teton National Park, WY to ask: (1) How would subalpine fires and forest structure be different if fires had not been suppressed during the last three decades? (2) What is the relative influence of climate change versus fire management strategy on future fire and forests? We contrasted fire and forests from 1989-2098 under two fire management scenarios (managed wildfire use and fire suppression), two general circulation models (CNRM-CM5 and GFDL-ESM2M), and two representative concentration pathways (8.5 and 4.5). We found little difference between management scenarios in the number, size, or severity of fires during the last three decades. With 21st-century warming, fire activity increased rapidly, particularly after 2050, and followed nearly identical trajectories in both management scenarios. Area burned per year between 2018-2099 was 1,700% greater than in the last three decades (1989-2017). Large areas of forest were abruptly lost; only 65% of the original 40,178 ha of forest remained by 2098. However, forests stayed connected and fuels were abundant enough to support profound increases in burning through this century. Our results indicate that strategies emphasizing managed wildfire use, rather than suppression, will not alter climate-induced changes to fire and forests in subalpine land
