“…Surface and subsurface accumulation of K from excreta in this zone is in agreement with other pasture studies based on zone sampling (Wilkinson et al, 1989;Williams and Haynes, 1992). In a grazing study in Venezuela, Buschbacher (1987) determined that >50% of the excreta was concentrated in the one-third of the pasture nearest lounging areas, while 40% of the pasture area received < 15% of the excreta. These results indicate that inclusion of soil cores from the one-third of the pasture closest to lounging areas in a composite sample for the entire pasture may result in an overestimation of the K status of most of the pasture (Kretschmer, 1958).…”

“…The productivity of bovine livestock (heads/ha) of our sample was similar to the Amazon average and around the double the Pará average (R. Walker et al 2013). The income values found by Buschbacher (1987) on the first decades of Transamazon colonization, between 50 to 104 USD/ha, were less than those in our results. On the other hand, our average income was less than half of the 372 USD/ha found by Garret et al (Garrett et al 2017), but his calculations considered some largeholders "outliers", with more than 2000 USD/ha.…”

“…By 1980, the Brazilian Amazon had 16 million heads of cattle and more than 7.5 million hectares of pasture, all fomented by the government (Poelhekke 1986). Despite the thenconsidered economic risk of cattle production in the biophysical conditions of Amazon basin (Buschbacher 1986(Buschbacher , 1987Fearnside 1979;Hecht, Norgard, and Possio 1988;Smith 1978), the bovines presented a healthy response with good rates of animal growth (Veiga et al 1996;Walker et al 2009). Moreover, ranchers enjoyed minimal land prices and low costs to convert forest into pasture (Bowman et al 2012).…”

“…However, scaled up cacao plantations would be restricted by favorable biophysical conditions (Pacheco 2009;Schroth et al 2016) regarding the predominant poor soils of Amazon basin (IBGE 2008b;Sombroek 1984). This is not a problem for cattle ranching (Buschbacher 1987;Walker et al 2009). Moreover, the adoption of livestock rather than cacao has other economic and cultural reasons besides just biophysical conditions.…”

many people, that collaborated during this long journey. I would like to give my sincere acknowledgements to everyone who contributed, directly or indirectly, to this work. From the ideas, the planning, the fieldwork, the analysis, the writing… It wouldn't be possible to make this alone. First, to my parents Marcia and José Roberto, my brothers Pedro and Lucas, my lovely grandparents Maria and Encarnação and all my family. Underlining my uncles Lena, Paulo and Cristina for the motivations. Also, my brother Lucas, for all the advices, inspiring reflections and reviews. To Scooby (in memoriam) and related learnings of life. No words would describe how much they mean for my walk until here. I am very thankful to every support and incentive they have given. The family farmers Joanira and "Manelão" (in memoriam) from Anapu for their conviviality and, in special, to their daughter Vanice, who has accompanied my "pathway" with all her joviality and vibrant stimulus, but also a lot of patience for the hard moments, with love and partnership. The Professor Dr. Edson Vidal who dedicates his life to narrow São Paulo's students and Amazon forest, creating a "real bridge" of forestry connections. I am one who walked through that "bridge" and, since then, I feel there is no way back. More than accepting me, he trusted in our challenging proposal of working in the Transamazon highway without appropriate funds. Thank you so much to make this dream reality. My PhD candidature followed my masters with Professor Dr. Flávio Gandara, who has been my supervisor and "academic guide" since the undergrad. He definitively makes part of my professional and personal evolvement. I am immensely grateful to all his advices and shared experiences along this walk. Also, to his Lab team (LAGRO), mainly Elza Ferraz and Chico for the required field equipments. To the Professor Dr. Benno Pokorny who opened the doors of University of Freiburg to cooperate with our study. He challenged me to think, from a "naturalist", as a "social scientist". Patiently, he has been very helpful to make me better understand the meaning of humanities behind the gross data, also to think about the Amazon regarding a sustainable rural development in a broader sense. His contributions undoubtedly made this thesis much better, as well as me. My sincere acknowledgements.

“…The Monkey Islands cover less than 1 ha of land, and thus the income gained per unit area is quite high compared to income from national parks or most forms of agriculture or cattle ranching (Table I). Studies that explored the economic value of biodiversity reported that interactions among tourists, their effects on natural areas, and adequate management plans can be important for the development of sustainable local communities [Bookbinder et al, 1998;Buschbacher, 1987;Curran et al, 2002;Draper, 2000;Green & Donnelly, 2003;Li & Han, 2001;Noronha et al, 2002;Peters et al, 1989;Rico-Gray et al, 1991;Sedjo, 1983]. In this way, the economic benefit of ecotourism to Los Tuxtlas shows how the Monkey Islands are an important resource for maintaining the stability of the local community.…”

This study evaluates the popularity and economic impact of Las Islas de los Changos (the Monkey Islands) as an ecotourism site on Lake Catemaco in the Los Tuxtlas region of Veracruz, Mexico. Two small island colonies of exotic primates, stumptail macaques (Macaca arctoides), have proved to be highly beneficial for the local economy as the main attraction for tourists in this region. From July 1991 to June 1992, data were collected on the number of tourists who took boat trips to visit the primates, and the amount of money spent on tours to the islands. The data suggest that at least 28,470 passengers visit these primate troops annually and spend approximately 88,970 U.S. dollars (USD). Follow-up questionnaires during July 1997 to June 2000 to hotelkeepers and tourist boat operators identified the Monkey Islands as the primary destination for tourists to this region. A comparison of the net income obtained by local ecotourism operators with wages earned through other types of employment in the Los Tuxtlas region, such as working in natural reserves, agriculture, or renting grazing land for cattle, show the relative importance of Las Islas de Los Changos in sustaining the local economy.
