“…These three variables do not always change together, and in such cases, vegetation differences usually have priority (Jepson Flora Project, 2022). In some cases, transitions in vegetation occur gradually and there is no apparent botanical basis for drawing a sharp line (Tunnell & Judd, 2002). Where this occurs, the limits primarily follow river valleys and the continuation of the Laguna Madre (The START group, 2007).…”

“…Where this occurs, the limits primarily follow river valleys and the continuation of the Laguna Madre (The START group, 2007). Together, the Laguna Madre of Texas and the Laguna Madre de Tamaulipas form the largest hypersaline system in the world (Delphi, 2020; Tunnell & Judd, 2002). Vegetation types in Spanish according to Miranda and Hernández‐Xolocotzi (1963) are mentioned between quotation marks when it is relevant to refer to a specific vegetation type, given that the classification system of the aforementioned authors uses local names that find their origin in native languages that historically delimited those vegetation types, and are therefore very specific.…”

Mexico's extraordinary tree diversity is threatened by the increasing demand for resources because of the tenfold population growth in the last century. The conservation status of trees and both urban and rural livelihoods are also negatively affected by agriculture, mining and tourism. Nearly 60% of the Mexican endemic and near endemic tree species whose conservation status we have assessed for the Red List of the International Union for Conservation of Nature are threatened, almost double the percentage of threatened trees worldwide. If no measures are taken to protect this tree diversity properly, these resources will be forever lost for human sustainability. Summary• Mexico is floristically the fourth most species-rich country in the world. Currently, 3620 native tree species are reported from this country. Mexico has been a forerunner at global level in recognising the need for plant conservation, yet this is in stark contrast with governmental programmes and actions, past and present that negatively affect(ed) immense areas of primary vegetation. In the framework of the Global Tree Assessment, to date, we have assessed the conservation status of nearly 1500 Mexican endemic and near endemic tree species for the International Union for the Conservation of Nature (IUCN) Red List, the distribution data of which we use here for a first meta-analysis of conservation statuses and spatial distribution patterns in a newly delimited area we call Natural Mexico.• Our database consists of 112,416 taxonomically and geographically very carefully curated distribution points of 1474 tree species endemic to Mexico and adjacent areas, belonging to 98 flowering plant families. The extensive curation methodology we consider essential for both research and conservation purposes is emphasised.

Mollusk death assemblages are formed by shell remnants deposited in the surficial mixed layer of the seabed. Diversity patterns in tropical marine habitats still are understudied; therefore, we aimed to investigate the taxonomic, phylogenetic, and functional diversity of mollusk death assemblages at regional and local scales in coral reef sands and seagrass meadows. We collected sediment samples at 11 sites within two shallow gulfs in the Northwestern Caribbean Sea and Southeastern Gulf of Mexico. All the shells were counted and identified to species level and classified into biological traits. We identified 7113 individuals belonging to 393 species (290 gastropods, 94 bivalves, and nine scaphopods). Diversity and assemblage structure showed many similarities between gulfs given their geological and biogeographical commonalities. Reef sands had higher richness than seagrasses likely because of a more favorable balance productivity-disturbance. Reef sands were dominated by epifaunal herbivores likely feeding on microphytobenthos and bysally attached bivalves adapted to intense hydrodynamic regime. In seagrass meadows, suspension feeders dominated in exposed sites and chemosynthetic infaunal bivalves dominated where oxygen replenishment was limited. Time averaging of death assemblages was likely in the order of 100 years, with stronger effects in reef sands compared to seagrass meadows. Our research provides evidence of the high taxonomic, phylogenetic, and functional diversity of mollusk death assemblages in tropical coastal sediments as result of the influence of scale-related processes and habitat type. Our study highlights the convenience of including phylogenetic and functional traits, as well as dead shells, for a more complete assessment of mollusk biodiversity.
