Temporal geographic variation in lambing seasons was statistically assessed for 22 populations, including 5 ecological races, of North American bighorn sheep (Ovis canadensis ssp.) from the Canadian National Parks (52° N) to western Texas (30° N). Throughout their distribution, bighorn lambing occurs coincident with the period of vegetative development when the environmental regime ameliorates neonate survival. Analyses generally demonstrate later and shorter lambing seasons in higher latitudinal populations (P < 0.001). Inception of lambing occurs later with colder temperatures, increased snowfall, at higher latitudes and elevations, and with later and shorter growing seasons [Formula: see text]. Additionally, a significant (P < 0.001) divergence in the reproductive "strategy" (median onset and duration of lambing) exists between bighorn herds of the Sierra Nevada Mountains, California (37° N) and the Desert National Wildlife Range, Nevada (36° N) as a result of two distinct, but adjacent environmental regimes. Lambing in northern populations is cued to a brief, relatively predictable period of plant growth. Southern bighorn protract lambing such that some recruitment coincides with relatively unpredictable plant growth, triggered by erratic rains.

The article is divided into two parts. Its first part analyses the functions of environmental education and land sharing performed by national parks in Poland. The second part presents the transformations of both tourist and nature protection functions of 117 municipalities (gminas), territorially linked with 23 national parks in Poland. For this purpose, a statistical analysis was carried out, applying linear ordering methods—synthetic development measures (SDM) were used. Subsequently, a comparative analysis of municipalities in each of the defined areas was carried out, along with an assessment of the correlation between the level of the nature protection function and the tourist function development. The research covers the years 2001–2016. SDM of nature protection function and tourist function in the municipalities linked with national parks indicate stability of the nature protection function as well as dynamic changes in the tourist function. It allows rejecting the research hypothesis that national parks intend to block the tourist function of municipalities. The research findings indicate the need for cooperation between municipalities and national parks not only for the sake of nature protection, but also for the purpose of area economic activation.

Abstract The goal of the studies undertaken in Polish national parks was to determine noise threats, examine the resources, assess the quality of soundscapes and identify the possibilities of their protection. The questionnaire method used in the studies made it possible to identify the awareness of noise threats and the value of soundscapes according to the park service staff. In addition, the semantic differential and description methods were used to learn how students assessed the soundscape quality of Polish national parks. Finally, avenues of further research on soundscape in environmentally valuable areas were indicated. The research findings indicate that each national park in Poland is characterised by diverse and unique soundscapes and is subject to the pressure of road traffic and tourism resulting in noise hazards. The conservation of the acoustic values of parks is necessary and possible.

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.
