Like many species, the model plant Arabidopsis thaliana exhibits multiple different life histories in natural environments. We grew mutants impaired signaling pathways field experiments across species' native European range order to dissect mechanisms underlying this variation. Unexpectedly, mutational loss at loci implicated cold requirement for flowering had little effect on history except late-summer cohorts. A genetically informed photothermal of progression toward explained most...
Pressures are mounting for the adoption of a Global Biodiversity Framework that transforms conservation and sustainable use efforts worldwide. Underlying this challenge is biodiversity paradox: biological diversity predominantly concentrates in tropics, while human, institutional, financial resources primarily located at higher latitudes both north south. Addressing paradox requires expansion mobilization institutional around world. We outline model championed by IUCN Species Survival...
Societal Impact Statement Conserving trees is fundamental to maintaining forests, which are home about half of the global biodiversity and provide unmeasurable benefits people. Colombia has 5868 known species trees, 1148 endemic country. Unfortunately, 45% threatened with extinction, therefore, ecosystem services they might be in jeopardy. This study represents an important contribution conservation planning for a megadiverse country highlights critical considerations their conservation....
Two major lineages of beetles inhabit cycad cones in the New World: weevils (Curculionoidea) subtribe Allocorynina, including genera Notorhopalotria Tang and O’Brien, Parallocorynus Voss, Protocorynus O’Brien Rhopalotria Chevrolat, family Erotylidae, genus Pharaxonotha Reitter. Analysis 16S ribosomal RNA (rRNA) mitochondrial gene as well cladistic analysis morphological characters indicate four radiations, with a probable origin on Dioon Lindl. comparatively recent host shifts onto Zamia L....
Abstract Habitat degradation can result in drastic environmental changes potentially affecting the life‐history of populations and aspects reproductive biology genetic structure within among populations. Here, we explore how differences between subpopulations from contrasting habitats may affect mating availability, which turn will indirectly strength spatial a tropical rainforest cycad ( Zamia fairchildiana ). Subpopulations exposed to higher light availability degraded‐forest had male...
Eumaeus butterflies are obligate herbivores of Zamia, the most diverse neotropical genus cycads. Eumaeus-Zamia interactions have been characterized mainly for species distributed in North and Central America. However, larval host plant use by southern clade remains largely unknown, precluding a comprehensive study co-evolution between genera. Here, we combine fieldwork with museum literature surveys to expand herbivory records from 21 38 Zamia species. We inferred time-calibrated phylogeny...
The taxonomy of Zamia montana and Z. oligodonta, two poorly understood species occurring at high elevations in the Western Cordillera Colombia, is discussed. oligodonta was recently synonymized under montana, but information derived from recent field studies provided showing are quite distinct. A treatment both presented, including discussion major morphological differences between them also other South American with prominently-veined leaflets. conservation status evaluated.
Seed dispersal by animals in cycads is assumed to be rare and unimportant. We conducted a literature review of seed species the family Zamiaceae. found 71 reports animal Zamiaceae, mostly birds mammals small medium size; but only six studies natural populations Zamia species. also study primary secondary manicata Colombia. used camera traps for recording interactions with female cones mature seeds; marking experiment explore movement seeds away from immediate vicinity parental plant after...
Completar la Lista Roja de las Plantas Colombia es una metas principales Estrategia Nacional para Conservación (ENCP) y crucial planificación conservación flora del país. La serie Libro Rojo realizó primera contribución importante a nacional, desde el 2014 un equipo trabajo asociado ENCP Grupo Especialistas (GEPC) UICN han coordinado esfuerzos seguir avanzando en esta tarea. Al final 2022 nivel nacional alcanzó 12 % cobertura especies reportadas país año 2025 alcanzará al menos 25 %. Según...
Abstract Creating software tools that address the needs of a wide range decision-makers requires inclusion differing perspectives throughout development process. Software for biodiversity conservation often fall short in this regard, partly because broad decision-maker may exceed toolkits single research groups or even institutions. We show participatory, collaborative codesign enhances utility better decision-making planning, as demonstrated by our experiences developing set integrated...
Zamia orinoquiensis Calonje, Betancur & A.Lindstr., a new species from the western Orinoquía region of Colombia is described and illustrated. The segregated compared to Z. muricata Willd., latter which morphologically recharacterized, illustrated, recircumscribed include populations tropical dry forest moist forests in Lara-Falcón Formation Cordillera de la Costa natural regions Venezuela, as well Serranía Macuira La Guajira, Colombia. distinguished by its leaves bearing fewer,...
Zamia paucifoliolata, a new cycad species from the Pacific lowlands of Valle del Cauca, Colombia, is described and illustrated. It distinguished other by having an underground stem typically bearing large solitary leaves with eighteen or fewer leaflets, villous strobilar axes, microsporangia borne on both abaxial adaxial side microsporophylls, seeds that are longer than 18 mm. compared to Z. pyrophylla, cunaria, ipetiensis, which it most closely resembles.
La respuesta a la selección natural en caracteres cuantitativos una población depende de magnitud variabilidad genética y las correlaciones genéticas los rasgos, estos parámetros genéticos pueden diferir entre categorías rasgos.

Abstract The IUCN Red List assessments of Colombian flora significantly impact national public policy by informing conservation strategies and prioritizing areas for conservation. However, little is known about the distribution, status, or evolutionary history most epiphytes, which prevents development aimed at their protection. In this article, we present results extinction risk 290 species vascular epiphyte from Colombia, including 81 country endemics, using geographic occurrences obtained...
