“…Similarly, growth rates and individual body size are highly dependent on resource types and availability (Dmitriew, 2011; Dunham, 1978; Festa‐Bianchet et al, 2004). For instance, species diversity and especially invertebrates diversity and abundance are known to decrease with increasing salinity (Cunillera‐Montcusí et al, 2022; Ersoy et al, 2022; Finlayson et al, 2013; González‐Sansón et al, 2022; Kendall et al, 2022; Pinder et al, 2005). However, coastal habitats are also known to be highly productive interface environments (Hobohm et al, 2021) and arthropod (one of the main food source of toads, Wells, 2007) diversity and abundances have been shown to be relatively high in coastal habitats (Barrett et al, 2005; Brunbjerg et al, 2015; Polis & Hurd, 1996), notably because of the positive effects of both terrigenous and marine sources of nutrients on trophic webs (Polis & Hurd, 1996).…”

Body size is a critical component of organismal biology. Body size is known to be influenced by a plethora of environmental conditions, among which exposure to large scale variations of salinity has been comparatively overlooked. Yet, exposure to salinity is known to affect energetic allocation toward growth and reproduction. In this study, we investigated the morphological differences between inland and coastal individuals of spined toads (Bufo spinosus) in Western France. We measured adult morphology both outside and during the reproductive season on 190 individuals, and assessed reproduction in pairs originating from inland (N = 20) and coastal (N = 30) environments. Overall, we found that adult coastal toads were smaller and lighter than inland individuals. Reproductive correlates of these differences included lower fecundity and smaller egg size (but higher egg density) in coastal females. Interestingly, these differences were not allometric correlates of body size, as coastal females invested proportionally less in all components of reproduction (fecundity, egg size and egg protection). These results suggest altered resource allocation to growth and reproduction in coastal amphibians, which may be related to the marked spatial gradient of salinity (measured in reproductive ponds) and the associated costs of osmoregulation (higher osmolality in coastal individuals), for which local adaptation and higher tolerance to salinity remains to be tested.

“…En el norte, dos zonas son amplias (Los Colorados y Sabana-Camagüey), aunque con áreas comparativamente menores que las del sur, con unos 12,000 km 2 . En ambas predominan las aguas someras con fondos fango-arenosos y rocoso-arenosos, de origen coralino (Alcolado et al, 2007;González-Sansón y Aguilar-Betancourt, 2007). Estas cuatro zonas amplias de la plataforma alternan con otras donde la plataforma es estrecha, con fondos rocosos, bordeadas de arrecifes de coral y con mayor incidencia de las aguas oceánicas .…”

“…Las diferencias en la cantidad de especies también pudieran estar relacionadas con las características geomorfológicas y oceanográficas de cada región. Las zonas 2, 4, 6 y 8 poseen amplias plataformas con cayos de mangle, estuarios y otros accidentes geográficos (Alcolado, 1990;Alcolado et al, 2007;González-Sansón y Aguilar-Betancourt, 2007;Martínez-Daranas et al, 2008;Pina-Amargós et al, 2021), que pudieran favorecer una mayor diversidad de macroalgas. Por otra parte, las zonas 1, 3, 5, 7 y 9 son fundamentalmente ecosistemas con plataforma estrecha, pendientes abruptas, fondos rocosos, y poca incidencia de agua dulce .…”

Antecedentes y Objetivos: Desde la publicación del libro sobre las macroalgas marinas de Cuba en 2015 se han publicado nuevos registros y cambios taxonómicos. Por lo anterior, el objetivo del presente trabajo fue presentar una quinta revisión sistemática actualizada, que incluye Ochrophyta (Clase Phaeophyceae), Rhodophyta y Chlorophyta. Métodos: Se recopiló la información disponible en publicaciones científicas, tesis de licenciatura, maestría y doctorado, e informes científico-técnicos de especialistas reconocidos, considerando aquellas que no fueron comprendidas en la revisión anterior o que fueron publicadas después de 2015. Los taxones encontrados fueron ordenados sistemáticamente, los nombres actualizados y la sinonimia revisada según AlgaeBase y la literatura más reciente. Las especies se ordenaron alfabéticamente dentro de cada familia. La distribución de cada taxón se resumió para nueve zonas consideradas como Distritos Ecológicos (zonas) de la plataforma cubana.Resultados claves: Se presenta un listado florístico actualizado con 569 especies, una subespecie, 25 variedades y 21 formas. Se añaden a la anterior revisión 38 especies, de las cuales siete son nuevos registros para Cuba: Hydrolithon boergesenii, Neogoniolithon mamillare, N. propinquum, N. rhizophorae, Lithothamnion crispatum, Liagoropsis schrammii y Peyssonnelia rubra. Se da la distribución de cada uno de estos taxones en las nueve zonas de la plataforma cubana.Conclusiones: Las zonas que presentaron más especies son aquellas que han tenido un mayor esfuerzo de muestreo o donde predominan los fondos rocosos arrecifales, aunque no se han inventariado detalladamente las macroalgas en la zona mesolitoral, bahías y lagunas costeras.

“…The downstream area near the estuary of the Liaohe National Park is characterized as an estuarine region. Due to the estuary's rich nutrients, diverse habitats, and migratory pathways, the estuarine area is endowed with abundant biodiversity (Gonzaĺez-Sansoń et al, 2022). However, due to overfishing, environmental pollution, and other reasons, the diversity of fish in the Liaohe River has significantly deteriorated, and no reports of using eDNA metabarcoding to investigate fish diversity (Wei et al, 2023).…”

The escalating environmental changes are imposing multiple pressures on biodiversity conservation, thereby, more attention has been paid to fish diversity and community assembly patterns. Fish diversity in Liaohe River has deteriorated significantly due to overfishing, environmental pollution and other reasons, in addition, no fish survey related research has been published in Liaohe National Park in recent years. In order to study the diversity of fish species in the area and to investigate the presence of any invasive species. This study used eDNA metabarcoding to explore the distribution and diversity of fish communities in the Liaohe National Park. The study showed that a total of 54 species of fish from six orders, 14 families, and 39 genera were detected, meantime, the invasive species Lepomis cyanellus was found at two sampling sites. The α-diversity results showed that estuarine sites had the highest species diversity. The spatial structure of fish communities in the upstream and downstream reaches were similar as indicated by non-metric multidimensional scaling. In our study, the fish community is influenced by both deterministic and stochastic processes, with the stochastic processes being the main factor. The potential existence of L. cyanellus in Liaohe National Park might be resulted from aquaculture, ornamental pet trade, other economic fish farming, artificial release. The relatively low number of fish species in this study may be attributed to the limited number of sampling events and sampling sites. In addition to these factors, over exploitation of resources, water pollution, and the invasion of alien species have directly impacted the biodiversity of aquatic life. The results of this study lay a foundation for the future biodiversity investigation in National Parks of China, meantime, the use of eDNA monitoring is crucial to prevent, to control and limit the spreading of invasive species in advance.
