Development and conservation in the tropical forest frontier: a 50-year analysis of policy evolution and interplay in Marqués de Comillas, Chiapas, México

ABSTRACT Tropical forests are vital for global biodiversity and climate stability, but the political economy of deforestation and land-use change constantly challenges their integrity. In this article, we analyse 50 years of policy development in the municipality Marqués de Comillas, located in Selva Lacandona, Chiapas, Mexico, to understand how development and conservation priorities have evolved, interacted, and shaped land-use in a tropical forest frontier. By analysing peer-reviewed literature and empirical data, we identify five phases of policy continuity and change that have produced diverse socio-environmental outcomes. We reveal a persistent state-led prioritisation of rural development over environmental concerns, pursued through policies promoting settlements and agricultural expansion and exacerbated by external market forces. This focus has caused substantial ecosystem degradation and deforestation without significant livelihood improvements. Recent conservation initiatives, such as payment for ecosystem services, show potential for challenging the status quo by offering alternative livelihood opportunities benefiting both people and ecosystems.

Spatial Anaysis and Modelling to Mappping Priorities Areas for Restauration: Study Case: Natural Protected Area Montes Azules, Chiapas, Mexico

Natural Protected Areas play a fundamental role in the conservation of biodiversity and ecosystems throughout the world and are designated and managed with the purpose of preserving biological and cultural capital, ensuring the sustainable use of natural resources, and maintaining ecosystem services. The Montes Azules Biosphere Reserve, like other Natural Protected in Mexico, faces significant challenges such as deforestation, illegal logging, and loss of vegetation cover, as well as socio-environmental conflicts, factors that hinder the biological and cultural conservation of the area. Likewise, despite their importance, many Natural Protected face significant challenges in terms of effective monitoring and planning. The lack of adequate monitoring and planning strategies, as well as staff and budget, makes it difficult to assess the conservation status of these areas and to implement appropriate management measures. Therefore, creating specific monitoring tools is essential to periodically evaluate their conservation status and identify threats and pressures on ecosystems in order to design adaptive and effective management strategies. The objective of this study is to offer a first methodological approach to identify priority areas for restoration within the Montes Azules Biosphere Reserve, which will allow decision-makers to design and apply conservation strategies in the area. The determination of the priority areas for restoration was based on an environmental management process, where the Land suitability is the base for the territorial arrangement, which was modeled together with the current land use and land cover through rules of decision and having the natural protected area as a frame. For land suitability, the land classification system was used according to its use capacity or American system of the 8 classes developed by the Soil Conservation Service of the United States; for mapping land use land cover, an object base classification method was used. The total transformed area in 2023 occupies an extension of 39,475.38 ha, approximately 50% of this lands corresponds to sloping and very steep land and in some cases with shallow to very shallow soils, not suitable for agriculture. The area identified as priority zones for restoration corresponds to an extension of 19,514.5 ha, which represents nearly 50% of the transformed area, and 6% of the total of study area, from which 6,860.5 ha are top priority for restoration. As main conclusion can be said that the methodological proposal described here serves as a first approximation to identify priority zones for restoration in the Montes Azules Biosphere Reserve, allowing for a more detailed identification of these areas at the local level, which will allow decision-makers to design and apply conservation strategies in the area.

‘Sometimes they achieve a good life, sometimes they come back in a coffin’ – exploring social worlds of mobility at the communities of origin in Chiapas, Mexico

ABSTRACT Based on ethnographical and collaborative research conducted in the South Mexican region of The Lacandon Jungle, my paper explores how Indigenous peasant communities deal with the effects that various forms of mobility have on their social worlds. Combining decolonial work on Indigenous communality and transnational perspectives with a situational analysis approach, my research specifically focuses on collective processes of meaning-making in light of the increasing mobility among these communities’ members. By analyzing how the people who stay collectively organize the community’s social world, I position myself against approaches that reduce Indigenous movements to cultural policies, since such approaches overlook the relevance of anti-colonial resistance. My research shows that within the ‘Indigenous communal governance systems’, the departure of individual members plays a formative role for the entire community, shaping the resulting social relations and political practices. To ensure collective access to territory as a means of communal self-determination, a ‘transnational continuum of communality’ emerges between the communities of origin and their absent members.

Exploring local perceptions and drivers of engagement in biodiversity monitoring among participants in payments for ecosystem services schemes in southeastern Mexico.

Payments for ecosystem services (PES) are widely applied incentive-based instruments with diverse objectives that increasingly include biodiversity conservation. Yet, there is a gap in understanding of how to best assess and monitor programs' biodiversity outcomes. We examined perceptions and drivers of engagement related to biodiversity monitoring through surveys among current PES participants in 7 communities in Mexico's Selva Lacandona. We conducted workshops among survey participants that included training and field deployment of tools used to monitor biodiversity and land cover, including visual transects, camera traps, acoustic recorders, and forest cover satellite images. We conducted pre- and postworkshop surveys in each community to evaluate changes in respondents' perceptions following exposure to biodiversity monitoring training and related field activities. We also reviewed existing research on participatory environmental management and monitoring approaches. One quarter of current PES participants in the study area participated in our surveys and workshops. The majority stated interest in engaging in diverse activities related to the procedural aspects of biodiversity monitoring (e.g., planning, field data collection, results dissemination) and acknowledged multiple benefits of introducing biodiversity monitoring into PES (e.g., knowledge and capacity building, improved natural resource management, and greater support for conservation). Household economic reliance on PES was positively associated with willingness to engage in monitoring. Technical expertise, time, and monetary constraints were deterrents. Respondents were most interested in monitoring mammals, birds, and plants and using visual transects, camera traps, and forest cover satellite images. Exposure to monitoring enhanced subsequent interest in monitoring by providing respondents with new insights from their communities related to deforestation and species' abundance and diversity. Respondents identified key strengths and weaknesses of applying different monitoring tools, which suggests that deploying multiple tools simultaneously can increase local engagement and produce complementary findings and data. Overall, our findings support the relevance and usefulness of incorporating participatory biodiversity monitoring into PES.

Sustained participation in a Payments for Ecosystem Services program reduces deforestation in a Mexican agricultural frontier

Payments for Ecosystem Services (PES) provide conditional incentives for forest conservation. PES short-term effects on deforestation are well-documented, but we know less about program effectiveness when participation is sustained over time. Here, we assess the impact of consecutive renewals of PES contracts on deforestation and forest degradation in three municipalities of the Selva Lacandona (Chiapas, Mexico). PES reduced deforestation both after a single 5-year contract and after two consecutive contracts, but the impacts are only detectable in higher deforestation-risk parcels. Enrollment duration increases PES impact in these parcels, which suggests a positive cumulative effect over time. These findings suggest that improved spatial targeting and longer-term enrollment are key enabling factors to improve forest conservation outcomes in agricultural frontiers.

The amphibians and reptiles of the Northern Selva Lacandona:

Chiapas harbors significant biological and cultural diversity. The region known as Selva Lacandona is an ideal example to study what is called the “biocultural axiom”. This neotropical region is inhabited by multiple indigenous groups, such as the Tsotziles, Tseltales, Tojolabales, Ch’oles, Kanjobales, Chujes, Mames, Lacandones (Hach Winik), and Zoques. The herpetofaunistic diversity of Chiapas is currently represented by 107 species of amphibians and 223 species of reptiles. In the Selva Lacandona region a total of 35 species of amphibians and 90 reptiles has been documented, with some areas still remaining to be formally explored. Traditionally, the use of natural resources by native indigenous communities has been linked to the selective use of those species that have economical, traditional, and/or magical-religious value. Many of these human groups have a deep traditional knowledge about the environment in which they live, as well as the diversity of plant, fungal, and animal species with which they have coexisted over millennia. The Nahá and Metzabok communities are inhabited by the Maya-Lacandón del Norte culture. The objective of this study is to identify the herpetofaunistic species diversity found within the Flora and Fauna Protection Areas (APFF´s) of Nahá andMetzabok. Additionally, we analyzed whether the Lacandones from the north have a herpetofaunistic ethnical taxonomic classification system. A total of 67 species that are recognized by the Lacandones were recorded for both APFFs. The Lacandones del Norte classify the herpetofauna into six groups, i.e., Ak (Turtles), Kan (Snakes), Ayim (Crocodiles), Torok (Lizards), Xut (Frogs), and Be’p (Toads). For Metzabok, the three most frequently mentioned species are Bothrops asper, Boa imperator, and Crocodylus moreletii. For Nahá, the three species of most importance are Basiliscus vittatus, Boa imperator, and Kinosternon leucostomum. The differenceslie in the fact that for the Lacandones of Metzabok, the most important animals are those that are represented in their oral narratives, while for the Nahá community; the most important species are those that they usually find on a daily basis when walking along the trails in the jungle.

Socioecological effects of swidden management in traditional Maya agroforests in the Selva Lacandona of Chiapas, Mexico

For millennia, Maya farmers (i.e., milperos) throughout Mesoamerica have managed milpa: sequential agroforests initiated by slashing and burning patches of secondary forest and then cultivating a diverse polyculture of trees and annual crops. To reduce greenhouse gas emissions associated with deforestation, the Mexican government and non-governmental organizations have urged milperos to cease burning. We collaborated with Maya milperos in several communities in the Montes Azules Biosphere Reserve region in Chiapas, Mexico to determine carbon retained as char in traditional milpas, carbon loss associated with burning, and effects of burning on soil quality. We found the carbon retention of char in Maya milpas (24 ± 6.5% of C in vegetation) is 4–1400% higher than other slash-and-burn agroecosystems reported in the literature. Burning resulted in significant carbon loss of 12.6 (±3.6) t C ha−1 yr−1, but this was partially mitigated by char production (3.0 [±0.6] t C ha−1 yr−1) and incomplete combustion of woody biomass. The effects of burning on soil were minimal, with the only significant changes observed being increases in pH, potassium availability, and cation exchange capacity (2, 100, and 7%, respectively). The mean residence times of charred materials were at least double that of uncharred biomass. While there is a risk that shortening fallow periods would undermine the sustainability of Maya swidden agroecology, proper management and secure land tenure can help maintain intensive production without enduring environmental degradation. The char produced in these swiddens and successional management could allow this agroforestry system to be a long-term carbon sink.

“Variable Effects of Tourist Presence on the Activity Budget of Alouatta pigra”

Background and Research Wildlife tourism has been considered a useful tool for conservation in some contexts and found to cause diverse effects on biodiversity. We investigated the effect of the number of tourists on wild black howler monkeys’ ( Alouatta pigra) behavior at the Montes Azules Biosphere Reserve (MABR), in the Lacandona forest in Mexico. Methods We used 5-min focal animal sampling, during dry and rainy seasons. We recorded five common behaviors in three wild groups naturally exposed to different degrees of human disturbance (Station, River and Board) without tourists, 5 and 10 tourists. Results Five and 10 tourists increased locomoting and reduced socializing, however, differently affected activities’ allocation time in the monkeys’ groups: in Board, 10 tourists reduced monkeys feeding; ii) in River, 10 tourists reduced socializing; and iii) in Station, 5 tourists increased feeding and reduced socializing, and 10 tourists reduced socializing. Conclusions Watching tourism activities affect behavior differently in groups of Alouatta pigra in the Montes Azules Biosphere Reserve in in the Mexican state of Chiapas, emphasizing the importance of regulating tourism programs for the conservation of endangered species. Implications for Conservation Although longer-term studies controlling for additional variables are needed to provide a more comprehensive understanding of the impact of tourism on wild howler populations, the results from this study remain valuable as a baseline for understanding such effects and for proposing initial strategies to reduce tourism-induced disturbance.

Deforestation increases the abundance of rodents and their ectoparasites in the Lacandon forest, Southern Mexico

Introduction: An important ecosystem service tropical forests provide is disease control. However, few studies have focused on analyzing how species more suitable to be zoonotic vectors are affected by deforestation. Objective: We evaluated how deforestation affects the abundance and species richness of rodents and their associated ectoparasites in Marques de Comillas, Chiapas, Southern Mexico. Methods: We captured rodents in 6 landscape units (LU), 1 km² each, with different percentages of tree cover (0.7, 5, 40, 46, 78, and 95 %). In each LU we set 90 Sherman traps that remained active 24 hours for 7 days during two sampling seasons in October 2019, and September 2020. All the captured rodents were checked for ectoparasites in their fur, which were collected to be identified at the lab. Results: We captured 70 rodents of five species: Sigmodon toltecus, Heteromys desmarestianus, Ototylomys phyllotis, Peromyscus mexicanus, and Oryzomys couesi. Rodent abundance increased with forest loss (R² = 0.706, P = 0.022). The greatest richness of rodent species occurred in sites with intermediate forest cover (40 % and 78 %). The most abundant species were S. toltecus (N = 45) followed by O. couesi (N = 9), these species dominated in sites with less forest cover. We recorded a total of 23 different ectoparasites, from these we identified 15 at the species level and eight at the genus level. We detected three species of ectoparasites (Amblyomma sp., Ornithonyssus bacoti, and Androlaelaps fahrenholzi) known to be vectors of zoonotic diseases. Conclusions: We found that the ongoing loss of forests promotes the proliferation of zoonotic disease vectors, which can potentially increase the frequency of affectation among the local population.

REDATION ATTEMPTS OF THE GRAY FOX (Urocyon cinereoargenteus) AND THE NEOTROPICAL OTTER (Lontra longicaudis) BY THE CENTRAL AMERICAN BOA CONSTRICTOR (Boa imperator) IN THE NORTHERN PORTION OF THE SELVA LACANDONA, CHIAPAS, MEXICO

Predator-prey interactions in the wild are scarcely observed or photo documented. This kind of natural history information is vital to understanding trophic chains and the ecology of the species involved. We present relevant new information regarding the diet of the Mesoamerican Boa (Boa imperator) in the northern region of the Selva Lacandona in Chiapas, Mexico. We expect that this information will be beneficial for the understanding of trophic webs in this multicultural and biodiverse region from southern Mexico.

Evidence of large water-level variations found in deltaic sediments of a tropical deep lake in the karst mountains of the Lacandon forest, Mexico

Lake Tzibaná is one of the largest (1.27 km2) and deepest (Zmax = 52 m) karstic lakes in the UNESCO’s Biosphere Reserve “Nahá-Metzabok” and in the Lacandon Forest, southeastern Mexico. It archives sediments from multiple sources and the inflowing Nahá River forms deltaic deposits. In 2019, the water level in Lake Tzibaná declined by ~ 15 m, persisting for 4 months and exposing the Nahá River Delta. A geophysical profile on the exposed delta revealed an accumulation of ~ 20 m of such deposits. Three sediment outcrops from an inactive channel in the Nahá River Delta, which ranged in height from 0.6 to 1.43 m, were sampled and a multi-proxy analysis of biological remains and geochemical variables was conducted. Four facies were observed: (1) massive-coarse sand, (2) fine sand, (3) dark leaf litter and (4) massive silty clay, each characterized by specific microcrustacean, testate amoebae and diatom taxa. Six dark leaf litter horizons were radiocarbon dated and revealed a complex depositional history including inverted ages making the establishment of an age model difficult. Nevertheless, past lake-level changes and the formation of the four facies match three characteristic water-level stages, which can also be observed on recent satellite images: (1) Massive-coarse sand deposits, with compositional and sedimentological characteristics of a shoreline environment and fluvial lateral banks, were formed during large-magnitude reductions in the lake level, similar to the one in 2019, (2) Interbedded layers of fine sand and dark leaf litter, currently found in low-energy fluvial environments, were formed during shorter and less pronounced decrease intervals, and (3) Massive silty clay, with distinctive microorganisms from low-energy lacustrine environments, is deposited during high water-level stages, when the delta is covered by water. Our findings illustrate how hydrological changes alter sedimentary dynamics in deltaic areas of lakes. Despite the complexity of their depositional processes, deltaic records can serve as a complementary source of paleolimnological information to records from distal zones due to their sensitivity to variations in water level, especially during extreme and prolonged desiccation events. Future research should attempt to combine evidences from deltaic and sediment sequences from deeper zones of Lake Tzibaná to reconstruct water-level variations during the entire Holocene. Understanding past lake-level reductions is not only relevant for the local indigenous communities but also crucial for the conservation of this ecosystem of international importance.

Organic matter seasonality and ecosystem metabolism in two tropical first-order streams

Dissolved and particulate organic matter are the energy source for secondary production in forested streams. Cycling of or¬ganic matter and stream ecosystem functioning are linked to organic matter input and storage capacity and timing. This study assessed the seasonal variation (dry and rainy seasons) of environmental parameters, organic matter stock and input, and stream metabolism in two first-order tropical streams in the Selva Lacandona, Mexico. We also aimed to identify the drivers of organic matter and stream metabolism seasonality. We found seasonal variation in organic matter stock and input correlated with trop¬ical seasonality. Dissolved organic matter and seston increased in the rainy season, while benthic primary producers and leaf litter stock and input increased in the dry season correlated with lower water discharge. Gross primary production increased in the dry season, while ecosystem respiration did not differ between seasons. Seasonality defined by the rainfall pattern and its effect on stream hydrology is the main driver of organic matter dynamics in tropical streams. However, environmental parameters and organic matter stock and input were not good predictors of stream metabolism.

Habitat use and activity patterns of ungulates in a tropical rainforest of southern México

Baird’s tapir (Tapirella bairdii), white-lipped peccary (Tayassu pecari), and collared peccary (Dicotyles tajacu) sympatrically occur in the Lacandon Forest of Chiapas, México. These species contribute to maintain ecosystem dynamics through herbivory, seed dispersal, and seed predation, constituting important prey for large carnivores and hunters. We analyzed activity patterns and habitat use of the three focal species to assess the degree of temporal and spatial habitat segregation among them in Montes Azules Biosphere Reserve (REBIMA) and surrounding communities. Between February and October 2015 we deployed camera-traps during 8,463 camera-trap days to estimate the presence and activity of tapirs and peccaries in two habitat types: “conserved” (REBIMA), and “transformed” (community forests; AFC). Habitat use and activity patterns of tapirs and peccaries were assessed through logistic regression models. We found that Baird’s tapir was almost exclusively nocturnal with a trend towards crepuscular activity, while both peccary species were diurnal, therefore showing a high daily temporal segregation from the tapir. Both peccary species were similarly active in the two study sites, while tapirs were more active in continuous forest within the protected area. The occurrence of tapirs and white-lipped peccaries depended on the presence and proximity of water sources and roads. Our results suggest that spatial segregation of the habitat allows coexistence of both peccary species in the study area. AFC have potential for maintaining populations of tapirs and peccaries in the Lacandon Forest. Conserving these forests by local communities is essential to ensure the persistence of these mammals.

Reporte de seis casos de eclampsia en un hospital rural de la selva de Chiapas

Eclampsia is a relatively rare and unpredictable syndrome ofpregnancy-induced hypertensive disease, characterized bya tonic-clonic seizure state which may or may not presenthypertension or end-organ damage. It complicates approximately 3 out of 1000 pregnancies, with a high incidencein patients of low socioeconomic status and rural areas,women with pre-eclampsia, primiparous teen or multiparous women over 35 years old. We present the report of 6cases of eclampsia that occurred in a first level rural hospitalof attention in the state of Chiapas, located in the heart ofthe Lacandon Jungle. Most of them occurred in primiparousteen patients during labor, which exceeded 40 weeks ofgestation. All were promptly managed with support measures and magnesium sulfate neuroprotection, 5 of themreferred to the second level of the intensive care unit formore comprehensive care, the average length of stay was 2days. No one presented a new seizure. No adverse perinataloutcomes or maternal death were recorded. The pre-eclampsia-eclampsia syndrome is a problem with a high impact on pregnancy and a challenge for all three levels ofcare, but especially for care in rural areas and indigenousareas throughout Mexico, since, due to entrenched customs,patients omit prenatal control, in addition to living in placeswith difficult access to hospitals or clinics.Keywords: Eclampsia; pregnancy; hypertension; neuroprotection; magnesium sulfate; rural areas

Spatial distribution patterns of tick community structure in sympatric jaguars (Panthera onca) and pumas (Puma concolor) from three ecoregions in Mexico.

We examined tick communities on wild felid hosts in three ecoregions of Mexico. We collected 186 ticks of 7 species from 10 pumas (Puma concolor) and 9 jaguars (Panthera onca). Tick community composition varied across the ecoregions, and across host species within each region. Overall, Ixodes affinis, Amblyomma ovale, and Amblyomma tenellum were the most abundant species; however, only the latter two ticks were distributed across all three ecoregions, while I. affinis, along with Ixodes spinipalpis, Amblyomma inornatum, and Amblyomma parvum were restricted to more limited geographical regions. Ixodes affinis occurred strictly in southern tropical rainforest ecoregions and was significantly more abundant in Selva Lacandona compared with the Yucatán Peninsula. Amblyomma ovale was significantly more common in the tropical dry forest in the Pacific coastal ecoregion. Amblyomma tenellum abundance tended to be higher on jaguars, while I. affinis abundance was higher on pumas. Regional distribution patterns of some tick species (e.g., I. affinis and I. spinipalpis) may be determined by off-host environmental conditions rather than host factors. In contrast, at the local scale, occurrence and abundance of some tick species (e.g., A. tenellum, A. ovale and Rhipicephalus microplus) might be driven by ecological-host factors, such as habitat use or predator-prey relationships.

Monster plants: the vegetal political ecology of <u>Lacandonia schismatica</u>

This article presents a story about a plant – Lacandonia schismatica – which subverted disciplinary traditions in botany and reconfigured its geopolitical orders of knowledge. To tell this story, we focus on Lacandonia's 'plantiness', Lesley Head and colleagues' (2012) concept to signify each kind of plant's unique biophysical characteristics, capacities, and potentialities, and through which they co-produce the world. We trace how L. schismatica intervened in, and (re)configured processes of knowledge production, environmental politics, and identity formation in the Lacandon Forest, Chiapas, Mexico, where it was found. Lacandonia's plantiness came into being through sudden macromutations; this unexpected but viable plant species participated in reviving an old debate in evolutionary biology: macroevolution versus gradualism. We also analyze how Lacandonia's plantiness compelled shifts in environmental politics in Chiapas and identity formation in Frontera Corozal, the Chol community where L. schismatica was first located. We conclude with a brief reflection on the implications of vegetal ethics for addressing contemporary environmental crises.

TURISMO INDÍGENA: UNA ALTERNATIVA PARA LA CONSERVACIÓN DE LA RESERVA DE LA BIOSFERA DE MONTES AZULES, CHIAPAS, MÉXICO

Historically, indigenous communities in Latin America, have inhabited spaces that currently have great economic value due to their variety of natural resources. Under the discourse of sustainability, governments seek to preserve them under the figures of Protected Natural Areas, mainly the Biosphere Reserves. In that sense, indigenous populations have been inserted into tourism activity, under the discourse of sustainability because it coincides with their worldview of coexistence with nature. In some cases, tourism has participated as predation by external actors, but it also has become a new threat to the territory. This document aims to determine whether the strategy of incorporating the Lacandones, inhabitants of the Montes Azules Biosphere Reserve into tourism, is convenient for the conservation of natural environments and the improvement of the living standards of local populations; to the extent that has been the continue to be a dominant global discourse around which the introduction of tourism in indigenous communities close to protected natural areas.

Vulnerabilities and Threats to Natural Forest Regrowth: Land Tenure Reform, Land Markets, Pasturelands, Plantations, and Urbanization in Indigenous Communities in Mexico

Despite the economic and social costs of national and international efforts to restore millions of hectares of deforested and degraded landscapes, results have not met expectations due to land tenure conflicts, land-use transformation, and top-down decision-making policies. Privatization of land, expansion of cattle raising, plantations, and urbanization have created an increasingly competitive land market, dispossessing local communities and threatening forest conservation and regeneration. In contrast to significant investments in reforestation, natural regrowth, which could contribute to landscape regeneration, has not been sufficiently promoted by national governments. This study analyzes socio-ecological and economic vulnerabilities of indigenous and other peasant communities in the Mexican states of Veracruz, Chiapas, and Morelos related to the inclusion of natural regeneration in their forest cycles. While these communities are located within protected areas (Los Tuxtlas Biosphere Reserve, Montes Azules Biosphere Reserve, El Tepozteco National Park, and Chichinautzin Biological Corridor), various threats and vulnerabilities impede natural regeneration. Although landscape restoration involves complex political, economic, and social relationships and decisions by a variety of stakeholders, we focus on communities’ vulnerable land rights and the impacts of privatization on changes in land use and forest conservation. We conclude that the social, economic, political, and environmental vulnerabilities of the study communities threaten natural regeneration, and we explore necessary changes for incorporating this process in landscape restoration.
