“…Being the country with the especially largest area of the reviewed biomes, we already predicted to find Brazil as the leading Neotropical country with respect to available evidence on the consequences of plant invasions, especially throughout the mega-diverse and threatened Brazilian Atlantic Forest. Our results are consistent with recent work that found the Brazilian Atlantic forest to hold not only the largest volume of studies on invasive plant impacts in the country (Zenni et al, 2022), but also the largest number of invasive species (Dechoum et al, 2021) and naturalized plants , which draws our attention to an increased likelihood of more species becoming successful invaders in the Atlantic Forest and potentially causing novel environmental damages anytime soon (Rejmanék and Randall, 2004). Surprisingly, the country with the second highest number of publications was Argentina.…”

“…Despite the lack of impact studies for an entire Neotropical biome, Richardson et al (2009) has already pointed out that the impact of invasive plants on native pine forests is probably much greater than is showed in the literature, and that such impacts can probably be expected for other species and similar regions. Consistent with the review of Zenni et al (2022) on plant invasions in South America, our work stresses that the lack of concrete evidence on the ecological impacts of invasive plants in most neotropical countries is a worrying result, because many invasive and naturalized plant species have already been detected in some of those countries and recorded in their respective national lists (Zenni et al, 2022).…”

“…As well as these three protected areas, our study reports the presence of the species in six additional protected areas, three forest reserves, five biosphere reserves, and two Ramsar wetlands. The addition of M. charantia to the flora of several priority conservation areas highlights the lack of studies for protected areas, particularly on the status of alien plant species in continental Ecuador (Speziale et al, 2012;Yánez, 2016;Zenni et al, 2022).…”

Momordica charantia, una maleza trepadora introducida, es nativa del trópico y subtrópico de Asia y África y se encuentra ampliamente distribuida en Ecuador. En este estudio, examinamos la distribución espacio-temporal de los registros de M. charantia y evaluamos su riesgo de invasión para Ecuador. Se recolectaron ocurrencias de la especie de diversas fuentes (bases de datos y herbarios). Se analizó la distribución de la especie en Ecuador y en áreas prioritarias de conservación, considerando sus preferencias climáticas y ecosistémicas. Se realizó un análisis de riesgo de invasión para Ecuador Continental. Nuestros resultados indicaron que M. charantia fue reportada por primera vez en Ecuador en la región de la costa en 1846. La causa de su introducción es desconocida; sin embargo, una posible vía para su expansión podría estar relacionada con su uso como planta medicinal en Ecuador. Actualmente, la especie está naturalizada en Ecuador y se ha registrado en las cuatro regiones, incluyendo las Islas Galápagos. Se detectó la presencia de la especie en 18 áreas prioritarias de conservación, donde su abundancia parece incipiente y su erradicación factible. La ciencia ciudadana (i.e. iNaturalist) proporcionó la mayoría de los registros de la especie, resaltando su importancia para monitorear especies invasoras. Aunque M. charantia tiene una presencia limitada en ambientes naturales (el 89% de los registros se encuentran en áreas perturbadas), la especie fue categorizada como de “alto riesgo” debido a que en Ecuador hay regiones climáticamente adecuadas para su establecimiento. Además, M. charantia tiene una alta capacidad de dispersión a larga distancia y un considerable potencial para convertirse en maleza en cultivos, representando una amenaza para la agricultura. Destacamos que la presencia de M. charantia en áreas perturbadas podría constituir una fuente de propagación hacia áreas cultivadas, donde la especie podría comportarse como maleza. El manejo de las poblaciones de M. charantia cerca de los cultivos podría mitigar sus posibles impactos agrícolas.

“…Climate change has also been linked to reductions in biodiversity and increases in vulnerability (Miles, Grainger, & Phillips, 2004;Mittermeier & Scarano, 2013;IBPES, 2018;Hoveka, van der Bank, & Davies, 2022). Other threats include the escape of genetically modified organisms and alien species invasions (Trakhtenbrot, Nathan, Perry, & Richardson, 2005;Santos & Calafate, 2018;Zenni et al, 2022). Biodiversity plays a critical role in tropical ecosystem functions, such as carbon stock and uptake, which, according to the United Nations' Reducing Emissions from Deforestation and Forest Degradation (REDD+), imputes value in biodiversity conservation (Araújo et al, 2022).…”

This study presents a qualitative analysis of endangered species occurrences in conservation units of Rio de Janeiro, one of the largest Brazilian municipalities in population size. Increasing human activities trigger changes in biodiversity, promote fragmentation, and reduce species distribution ranges, which can ultimately lead to declines in population sizes. One of the main goals of protected areas (PAs), such as conservation units, is to protect and conserve biodiversity. Here, we compiled all vascular plant species recorded within Rio de Janeiro PAs by consulting the Reference Center for Environmental Information (SpeciesLink), Flora do Brasil (2020), and primary data records contained in management plans. We compared this compilation with the list of Brazilian endangered plant species, verifying whether the management plans presented specific programs for these species. Of the 60 surveyed PAs, 24 had records of endangered species and only 17 had management plans, 14 of which had a specific program that contemplated the monitoring and/or conservation of endangered species. A total of 70 endangered species were recorded. The highest numbers of endangered species were found in the Tijuca National Park (41) and the Pedra Branca State Park (17), the two largest PAs with the two largest forest fragments. Despite the high number of endangered species and the number of protected areas that harbor them, few internal programs address endangered species conservation and management. Thus, efforts to maintain endangered species in protected areas can be aided by field data collections that confirm their occurrence and maintenance in these PAs.
