Drivers and spatial patterns of avian defaunation in tropical forestsBackgroundTropical forests harbor an immense diversity of bird species, but hunting and wildlife trade are driving widespread declines in bird populations. Unlike habitat loss, hunting often occurs in seemingly intact forests, making its impact more difficult to detect. Birds are harvested for both subsistence (food) and commercial purposes (pet trade), but the spatial extent and drivers of avian defaunation remain poorly understood. This study aims to assess the factors influencing bird population declines and map defaunation patterns across tropical forests. Open access copy available |
Cascading effects of contemporaneous defaunation on tropical forest communitiesBackgroundDefaunation, caused by hunting and habitat fragmentation, is a major threat to biodiversity in tropical forests. It disproportionately affects large-bodied vertebrates, which play key roles as seed dispersers, seed predators, and herbivores. The loss of these animals can have cascading effects on plant populations, altering species composition, seed dispersal, and plant recruitment. This study reviews empirical evidence from 42 studies to understand how defaunation influences plant-animal interactions, plant demography, and overall community diversity.

Conservation social science: Understanding and integrating human dimensions to improve conservationBackgroundMany scholars believe that there is an urgent need to integrate social sciences into conservation efforts. Although researchers widely acknowledge the importance of understanding the human dimensions of conservation, social science insights remain underutilized in practice. Open access copy available |
Environmental governance and its implications for conservation practiceBackgroundEnvironmental governance is a growing field that expands conservation practice beyond traditional management approaches. Managers make operational decisions to achieve specific conservation outcomes, while governance involves the broader processes and institutions through which societies make decisions that affect the environment. Unlike management, governance incorporates diverse views, fosters networks, and supports hybrid partnerships among state and non-state actors, creating opportunities for shared learning.

The 2023 state of the climate report: Entering uncharted territoryBackgroundThe Earth faces a climate crisis as human activities increasing the release of harmful greenhouse gases, turning scientists' warnings of extreme conditions into reality. Climate records are breaking, causing widespread suffering. This report examines the global climate crisis, presenting key climate facts and policy recommendations for scientists, policymakers, and the public. It serves as an up-to-date resource on the escalating emergency. Open access copy available |
Climate Risk ManagementBACKGROUND:Worldwide efforts are underway to devise and apply strategies to manage these risks effectively. Key challenges in climate risk management include the integration of necessary scientific disciplines, articulating stakeholder values and objectives, and quantifying pivotal uncertainties and trade-offs, all of which are vital for crafting effective management strategies. The paper addresses the intensification of global climate risks driven by accelerating climate change. The authors review these challenges based on existing literature to identify potential avenues to overcome them. Open access copy available |
Advances and shortfalls in applying best practices to global tree‐growing effortsBACKGROUND:Over the past three decades, there has been a rapid increase in the number of organizations engaged in tree planting to meet international targets exceeding a trillion trees. These initiatives aim to sequester carbon, conserve biodiversity, enhance water quality, and reduce social inequity. Despite these goals, frequent failures and unintended ecological and social impacts have led to the creation of numerous best practice guidelines for reforestation. Open access copy available |
Livelihoods, Forests, and Conservation in Developing Countries: An OverviewBACKGROUND:Poverty is a huge challenge, with 2.8 billion of the world’s 6 billion people living on less than $2 a day. The paper highlights the alarming extent of poverty in developing countries and addresses the rapid deforestation, which compromises ecological integrity and exacerbates social inequities. The authors focus on exploring whether poverty alleviation and forest conservation can be aligned as complementary rather than conflicting objectives. Available with subscription or purchase |
Erythrina (Leguminosae: Papilionoideae): A Versatile Genus for Agroforestry Systems in the Tropics.BackgroundThe genus Erythrina (Leguminosae) plays a crucial role in tropical agroforestry systems. These trees are adaptable and widely distributed in tropical and subtropical regions, with over 100 species globally. Erythrina species are known for their rapid growth, nitrogen-fixing capability, and adaptability to various environments, including low-fertility soils. Historically, they have been integrated into agricultural systems as shade trees, live fences, and forage sources. The diverse ecological benefits of Erythrina highlight its importance in addressing food security, environmental conservation, and rural livelihoods in tropical regions. Open access copy available |
