Invasive species are of signi?cant concern, especially in mega-diverse countries, because they cause negative e?ects such as loss of native biodiversity, ecological alterations, disease spread, and impacts on economic development and human health. In mainland Ecuador, information on invasive invertebrates in marine ecosystems is scarce. The objective of this study was to describe and locate the invasive species present in the rocky shores of the intertidal and subtidal zones along 10 areas (83 sites) covering most of the Ecuadorian coast during 2015–2016. Benthic macroinvertebrates communities were measured over quadrats located randomly on a 50 m transect positioned parallel to the coast in the intertidal and subtidal zone, covering an area of 1,860 km2. Six invasive species were recorded: Arthropoda (Amphibalanus amphitrite), Cnidaria (Pennaria disticha, Carijoa riisei), Bryozoa (Bugula neritina), Rhodophyta (Asparagopsis taxiformis) and Chlorophyta (Caulerpa racemosa). The areas with highest abundance of invasive species were in Jama (not a protected area), Marine and Costal Wildlife Reserve Puntilla of Santa Elena and Santa Clara Island Wildlife Refuge (protected areas). The most abundant species was Carijoa riisei with a relative abundance of up to 80%. It was the most aggressive of the invasive species registered in the subtidal zone, mainly in northern centre of the Ecuadorian coast. C. riisei is growing on native coral (Pocillopora spp.) and on sessile macroinvertebrate communities (Pinctada mazatlanica, Muricea appresa and Aplysina sp.) that are being a?ected by its invasion. This study must be taken into account by local and regional government authorities to create public policy programmes of monitoring for surveillance and control of invasive species. These programmes should focus on integration of socio-economic and ecological e?ects. They should be complemented by experimental design and analysis of environmental variables to provide technical information for a baseline of bio-invasion analysis along the Ecuadorian coast and Galápagos, to avoid the expansion of invasive species negatively a?ecting the marine biodiversity of mega-diverse countries such as Ecuador and other countries of South America.

Agriculture and food production offer stable livelihood options to rural communities throughout Asia and the Pacific region. Even as the effects of globalization spread in the region, farm production – most often at the smallholder level – continues to be a family enterprise. A fair share of farmers in the region engages in subsistence farming and poverty is a common occurrence among them. Farm enterprises are mostly managed by family members and family labour is a critical asset and often the only reliable investment. As rural women and men toil to preserve their heritage and broaden their economic choices, their endeavours are made more difficult by a lack of resources and market fluctuations. Asian and Pacific farmers, both men and women, are guardians of biodiversity, household food security and providers of food to urban communities. In these small farm enterprises distinct gender roles and gender differentiated access to technology and resources are evident. This disparity is compounded by the neglect of investment in rural social infrastructures such as education, health care and communications. In such resource poor rural environments, the struggle by rural women for access to resources and services is inevitable. In many Asian and Pacific countries, substantial gender equality gains have been made in urban areas in education, health and employment. Yet rural women lag behind. Moreover, rural women’s work is multifaceted and demanding both as family workers and agricultural labourers. Social and economic indicators often do not do justice to their contributions. Development innovations such as microcredit and self-help groups promote rural women’s economic development, but emerging evidence suggests that gender equality in rural communities is far from an everyday reality. Persisting social biases and traditional perceptions and assumptions regarding women’s responsibilities and their capacities continue to hamper women’s progress. This publication presents an overview of both the substantial contribution made by rural women to the economies in the region and the persisting barriers to their advancement. The framework of analysis, data and information reviewed together illustrate the complexity of rural women’s work in the region and offer a broad perspective on women’s economic and social contribution as well as on the barriers they encounter in accessing resources.
