Research in animal ethics and Generation Z in the field of tourism is a little-explored topic. With a focus on the development of both research fields, the aim of this study was to determine if Generation Z in Spain justifies or rejects the use of animals in tourism attractions, and to establish which specific animal attractions are acceptable for Generation Z and which are not. The results indicated that Generation Z does not justify any of the animal attractions presented in the questionnaire. Generation Z does not accept any of the possible justifications for the existence of animal-based attractions, and all conditions under which animals must be treated at those attractions are important for Generation Z respondents. Females attach greater importance than males to all animal treatment conditions and express a greater rejection of all attractions as well as all justifications presented in the questionnaire.

Sustainability in tourism cannot be achieved without decent work, gender equality and empowerment of all women. Most of the workforce in the tourism sector is women, and although this sector offers great opportunities for empowerment and gender equality, there are many inequalities that occur in it. To find solutions it is necessary to have a greater knowledge, and therefore it is necessary to analyze how the gender equality research is progressing. The objective of this paper is to analyse how the concept of gender equality in tourism is present in academic research. For this purpose, a systematic review of the existing scientific literature is carried out, based on a bibliometric review of the works on gender equality in the field of tourism published in the Scopus database. The analysis carried out shows that, although there has been a year-on-year increase in publications related to gender equality in the field of tourism, there are still few studies focused on this subjetc, and that only in the last time have they been linked to the family. The analysis also reveals that only a few journals and authors concentrate publications related to gender equality in tourism.

Solo travel continues to be an under-researched area in the field of tourism, hospitality, and events. After the COVID-19 pandemic, it has become necessary to review the knowledge acquired so far. In addition, the 2030 Agenda calls for more studies to understand the relationship between gender and tourism. Because of these facts, and with the aim of analyzing the progress and gaps in academic publications on solo travel in recent years, a bibliometric and content analysis review of the existing scientific literature on solo travel published in Scopus, ProQuest, and the Web of Science in the last 5 years was carried out, focusing the analysis on the gender perspective applied to these investigations. The results showed that research focused on solo travel should increase; this research should segment solo travelers, and comparisons should be realized between those segments and with other tourists who travel accompanied. To do so, a consensual definition of solo travelers is necessary. In addition, research should be extended to other regions and expand the field of analysis beyond motivations, experiences, or constraints. Research focused on solo female travelers should continue because while women cannot travel under the same conditions as men effective gender equality cannot be achieved.

An increase is occurring year on year, especially from 2019, in publications related to education for sustainability development (ESD) in the field of tourism. The objective of this paper is to analyse how the concept of sustainability is present in education in this area. To this aim, this article carries out a bibliographic review of the existing scientific literature on the presence of sustainability in tourism training. As an empirical part of the work, a bibliometric review of the works published in the Scopus database on sustainability in tourism education is proposed. Through evaluation and relational methods, it is intended to know the reality of this trend in tourism education. The analysis carried out shows that publications related to ESD in the field of tourism started focusing on the environment to shift on economic and social issues with the passage of time, and that there is greater attention to EDS on university education.
