The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

A globally consistent scaling relationship reveals stabilizing effects of dominant species in plant communities

Ecography, EarlyView.
Despite extensive research, stabilizing mechanisms in ecosystems remain uncertain. Taylor's power law (TPL) is a pervasive ecological pattern that describes how variance scales with mean abundance (σ2 = aμᵇ). While TPL has been widely studied within populations, its role across species within communities and its implications for stability remain ...

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs

Ecography, EarlyView.
Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

Environmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

SOIL TILLAGE AND FERTILIZER EFFECTS ON SOIL MOISTURE RETENTION, GROWTH AND SEED COTTON YIELD OF THE POPULAR FK37 COTTON IN NORTHERN GHANA. [PDF]

Journal CleanWAS
Cotton is a cash crop and enhances farmer livelihoods in northern Ghana. However, cotton yields are diminished because of drought and poor agronomic practices that result in lower lint quality.

Enabling pastoralist management of rangelands to achieve Land Degradation Neutrality

Frontiers in Ecology and the Environment, EarlyView.
Rangelands cover 54% of the global terrestrial area and are threatened by land conversion and degradation, which erodes their global value and weakens the livelihoods of pastoralists who manage them. Sustainable Development Goal Target 15.3 on Land Degradation Neutrality (LDN) provides a framework for sustainable rangelands management, but countries ...

Human appreciation of flower colours as cultural ecosystem service in grasslands: A methodological approach

Grassland Research, EarlyView.
This literature‐based method estimates human appreciation of flower colours on target grasslands. Step 1: search literature sources (floristic surveys, national floras, web datasets and preference studies). Step 2: flower trait extraction (flower colour and area, flowering period and human colour appreciation scale).

Evapotranspiration Profiles and Trends in Seasonally Dry and Seasonally Humid Tropical Forests

International Journal of Climatology, EarlyView.
Moisture availability and vegetation are decisive factors in ET variations, which are greater in the Atlantic Forest. Precipitation contributes positively to ET variations (r = 0.20–0.67). Significant trends (p < 0.05) in ET were identified, with opposing patterns.
