Peromyscus Eremicus

San Benito Archipelago is internationally important for the conservation of 13 species of seabirds. San Benito Oeste, the largest and only inhabited island, was declared mammal-free in 2000 after a series of eradications conducted in collaboration between the fishing cooperative Pescadores Nacionales de Abulón, the Mexican conservation organization, Grupo de Ecología y Conservación de Islas, A.C., and the Mexican Government. The archipelago remained mammal-free until 2006, when an unusual invader, the Cedros island cactus mouse (Peromyscus eremicus cedrosensis), was accidentally introduced to San Benito Oeste island. The same collaboration scheme involving locals, conservationists, and authorities was once again put in motion, delivering tangible results. Research informed the mouse eradication strategy, the local community supported the operation, and the mouse eradication was successfully implemented in December 2013. To date (8 years later), no mammals have been recorded in the archipelago, which suggests community-led island biosecurity is working. In addition, this collaborative restoration work contributed to the creation of the Baja California Pacific Islands Biosphere Reserve, protecting 21 islands, including the San Benito Archipelago, and 97 islets in the Mexican Pacific.

Cedros Island

Background and Aims: Cedros Island is the southernmost outpost of the California Floristic Province, the largest island in the Californian archipelago, and home to a suite of endemic plants and animals. As such, it is an important resource within the Pacific Islands Biosphere Reserve, with many management concerns. The goal of this study was to document newly arrived plant species on Cedros Island, Baja California, Mexico.Methods: From the 8th to the 11th February 2019 we visited Cedros Island and made observations of plants around Cedros Village using the platform NaturaLista (iNaturalist).Key results: Thirteen new plant taxa were detected around Cedros village, all were non-native. These discoveries follow a very recently published checklist on the flora and suggest that new non-native plants are arriving rapidly. Conclusions: Recommended management implications include monitoring and eradication of new species, particularly at inhabited areas, and with priority given to highly invasive species such as Cenchrus setaceus and C. ciliaris.

This chapter discusses the Cardenista government’s attempt to find a solution to the foreseen threat of a mass return of Mexican migrants from the U.S. Chapter 3 details how the Cardenas administration established that only a strict selection of skilled agricultural labourers would be permitted to return, and details how the administration determined that individual Mexican states should accept responsibility for providing both housing and assistance for repatriated nationals. Drawing on an overview of the studies conducted by the Cardenas administration on the population of Mexican nationals living in the U.S., this chapter states that ultimately, it was proposed that 450,000 people could be resettled at the cost of 366,345,291 pesos, and that this figure was well outside the government’s budget. Lastly, this chapter notes that plans for a resettlement colony in Baja California- called “Mexico Libre”- were established but never came to fruition.

Different Levels

The Los Tuxtlas Reserve has been heavily deforested and fragmented since the 1970’s. Although the flora of Los Tuxtlas has been described previously, most floristic lists come from the large forest reserve of the Los Tuxtlas field station. Here we present a check list of Angiosperms recorded in 45 rainforest fragments (< 1 to 266 ha) located in three landscapes with different levels of deforestation. We sampled all trees, shrubs, lianas, palms and herbs with diameter at breast height (dbh) Ā 2.5 cm within ten 50 m x 2 m plots per fragment. We recorded 9,435 plants belonging to 73 families and 372 species. Fabaceae, Rubiaceae, and Moraceae were best represented. Eight species are classified as Endangered by the Mexican government, and five are human-introduced species. We conclude that the conservation and restoration of all the remaining rainforest fragments are necessary to effectively preserve the plant diversity of this region.

Mexican Populations

The rainbow pearl oyster Pteria sterna is distributed along the Mexican Pacific coasts and Gulf of Baja California, where it represents a great economic potential. Five sampled populations collected in Baja California were used to screen two mitochondrial DNA genes that have proven useful in population genetics studies of several other bivalve species. The lack of polymorphism detected in these samples suggests a recent event of very low population size, most likely a founder event, which is congruent with the absence of P. sterna in the fossil records in Baja California.
