Among the main purposes of the program, it seeks to encourage the advance of environmental habits in public officials through environmental education. [Objective]: To determine if the educational and communicational campaigns promoted by the program have generated changes in the environmental habits and behaviors of civil servants. [Methodology]: The combined method was used, and for this purpose a survey was designed, on a universe of 25 000 employees obtaining a sample of 270 cases, with a confidence level of 90 % and an error level of 5 %. In addition, 15 in-depth interviews were conducted. The results were analyzed separately and then a cross analysis was developed. [Results]: Officials recognize changes in habits favorable to environmental care in their institutions, although these are not generalized. [Conclusions]: While the Green State accreditation program does induce changes in habits and behaviors among public employees, it requires additional reinforcement in the promotion of its educational strategies and modifications in certain requirements to fully achieve its goal in non-formal environmental education. Furthermore, the findings may be useful for Latin American States to adopt pro-environmental actions in the administrative functioning of their public institutions..","PeriodicalId":513845,"journal":{"name":"Revista de Ciencias Ambientales","volume":"59 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Costa Rica, the payment for environmental services (PSA) represents a mechanism to protect forests on private farms, but it lacks specific indicators on the state of biodiversity and forest conservation. [Objective]: To analyze the use of acoustic monitoring for ecosystem assessment at 11 sites in the Osa Peninsula, nine on private farms, and two sites within Corcovado National Park. [Methods]: Soundscapes were recorded from May 25 to June 1, 2021, using acoustic recorders. It was analyzed the behavior of six acoustic indices at each sampling site and applied an automated detection analysis of vocalizations of two representative bird species of the area. [Results]: It was found that the most fragmented sites presented higher activity, energy, and acoustic diversity, possibly due to edge effects and ecotones present, as well as a high forest component in the surrounding matrix. Automated vocalization detection indicated that the species Hylopezus perspicillatus turned out to be more sensitive to differences in the landscape than Trogon bairdii. [Conclusions]: The use of acoustic indices, although it associates features of the degree of conservation, was not a differentiating element of the quality of the ecosystem in the evaluated farms. The monitoring ofspecies through the detection of their vocalizations was promising. A careful and rigorous sampling design, with moresampling points per site, is recommended to achieve accurate measurements and avoid bias in the analysis.","PeriodicalId":513845,"journal":{"name":"Revista de Ciencias Ambientales","volume":"172 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140456261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Franco es una especie forestal de gran importancia por sus servicios ecosistémicos y su comercialización. Actualmente, se ha documentado que el cambio climático está afectando las poblaciones del norte del continente; sin embargo, no se ha evaluado cómo afectaría esto a la distribución de la especie en el futuro. Objetivo El objetivo de este trabajo fue modelar la idoneidad ambiental y la distribución potencial de P. menziesii en 3 periodos (2040, 2060 y 2080). Metodología Se estimó la idoneidad y distribución potencial, con base en registros y variables bioclimáticas, con ayuda de MaxEnt; se realizaron transferencias a 2 escenarios de emisiones de carbono en 3 periodos; por último, se evaluó la pérdida de extensión y disminución de idoneidad ambiental en porcentaje. Resultados P. menziesii tiene una distribución potencial actual de 164 110 km2, las zonas con mayor idoneidad ambiental (> 0.5) se ubicaron en el norte del país, específicamente en los estados del norte. No obstante, bajo los escenarios de cambio climático, estas áreas sufrieron mayor disminución de la idoneidad ambiental (> 50 %) y se redujo su extensión entre 50.7 % y 92.6 %; en contraste, las poblaciones más resilientes contra el cambio climático fueron las del sur. Conclusiones Pseudotsuga menziesii se ve favorecida por las bajas temperaturas, debido a esto, se espera un decrecimiento drástico en su distribución potencial. Aunada a ello, la idoneidad ambiental bajará a más del 50 % en las regiones norte de la nación. Con una pérdida drástica de superficie, la prevalencia de la especie pudiera encontrarse en un punto de declive.
