Gene Flow and Vertical Stratification of Pollination in the Bat-Pollinated Liana <i>Marcgravia longifolia</i>. [PDF]

Ecol Evol
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest. [PDF]

Ecol Evol
Collared peccary wallows are used by a diverse assemblage of vertebrates in a Central American tropical wet forest. Wallows had significantly higher vertebrate activity and diversity compared to surrounding forest. Wallow visitors included 13 amphibian, 2 reptile, 11 bird, and 16 mammal species, engaged in behaviors including reproduction, drinking ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Growth-defense trade-offs promote habitat isolation between recently-diverged species. [PDF]

Ecol Evol
Growth–defense trade‐offs have long been implicated in tropical plant diversity, but how do these tradeoffs contribute to reproductive isolation? This study characterizes growth–defense trade‐offs between two recently diverged tropical plants and explore their role in maintaining strong habitat isolation.

Evaluación de la diversidad de plantas de sotobosque en plantaciones de pino Szemao (Pinus kesiya var. langbianensis) en Yunnan, China

Collectanea Botanica, 2012
La sostenibilidad es un objetivo clave para la gestión tanto de bosques naturales como de plantaciones, mientras que los estudios sobre biodiversidad constituyen herramientas muy útiles para mejorar la conservación de especies amenazadas. El pino Szemao (

Sequía experimental en plántulas en un claro y en el sotobosque de un bosque de niebla, Veracruz, México

Acta Botanica Mexicana, 2022
Antecedentes y Objetivos: Se espera que las sequías inducidas por el cambio climático afecten al bosque de niebla. Como los rasgos funcionales son indicadores útiles del desempeño de especies vegetales, el objetivo de este trabajo fue determinar el ...

Desplazamiento del Hábitat de Macrolíquenes del Bosque Montano en un Escenario de Calentamiento Global en el Noreste de los Andes Venezolanos

Anales del Jardín Botánico de Madrid, 2023
Se estimaron los riesgos de pérdida “local” y “total” de hábitats de macrolíquenes considerando la migración ascendente debido al calentamiento “global” previsto para el presente siglo por el IPCC.

Source height and contact with terrestrial soil drive transplanted epiphyte performance

Journal of Ecology, Volume 111, Issue 11, Page 2388-2400, November 2023., 2023
Tropical vascular epiphytes, such as this orchid Peristeria pendula, performed worse when experimentally transplanted to new substrates in contact with terrestrial soil, versus substrates just above the soil surface. The results are some of the first empirical data supporting the epiphyte enemy escape hypothesis.

Vertically stratified frugivore community composition and interaction frequency in a liana fruiting across forest strata

Biotropica, Volume 55, Issue 3, Page 650-664, May 2023., 2023
Our findings suggest a continuous shift in the frugivore community composition along the vertical gradient of a plant species fruiting across forest strata, from a few generalized frugivores in the understorey to a diverse set of specialized frugivores in the canopy.

Bird species occupancy trends in Southeast Mexico over 1900–2020: Accounting for sighting record absences

Journal of Animal Ecology, Volume 92, Issue 3, Page 606-618, March 2023., 2023
This article accounts for species absences before occupancy analyses, addressing a long‐standing concern of whether absence is true or due to low sampling effort. The authors affiliate long‐term bird species trends with functional traits in a lowland tropical rainforest landscape in southeast Mexico to help guide land management and conservation ...
