Summary: The study found that the evolution of traplining in hummingbirds involves morphological specialization through the coevolution of longer bills with long-tubed flowers. It was previously believed that this specialization was irreversible and an evolutionary dead end, but the study discovered multiple independent transitions to traplining and suggested that it does not lead to lower rates of diversification.

Summary: This study examines the technical efficiency of Dutch indoor vegetable farms during the period of 2006-2016 using Data Envelopment Analysis (DEA) and bootstrap truncated regression model. The results show that technical inefficiency exists in energy, materials, pesticides, and fertilizers inputs among indoor growers, and enhancing farmers' ability to reduce this inefficiency can improve farm competitiveness and mitigate environmental impacts.

Summary: This study finds that both specialized economy and diversified economy play important roles in promoting the growth of GTFP, with the industrial complementarity in the diversified economy showing the strongest effect. Furthermore, the specialized economy mainly promotes GTFP growth by improving technological efficiency and promoting technical progress, while the diversified economy primarily achieves this goal by promoting technical progress and narrowing the technological gap.

Summary: Mono-cropping, declining farm profit, climate change, and food insecurity are major concerns in the agricultural production system in the Eastern Gangetic Plains. A study conducted in Bihar, India, showed that crop diversification with vegetables and legumes can significantly increase productivity, profitability, and soil health in the region.

Summary: Previous studies on the impact of firm growth on survival have overlooked the influence of agglomeration externalities. This study, based on data from Chinese manufacturing start-ups, found a U-shaped relationship between growth and survival risks, and identified different moderating effects of various agglomeration externalities on this relationship.

Summary: Trademark research in the intersection of regional and innovation studies has yielded stylized facts, methodological lessons, and policy insights that highlight the significance of intangible assets for regional resilience and growth. Despite the recent attention, there are still opportunities for further research in the areas of innovation/entrepreneurship geography and regional specialization/diversification.

Summary: Becker and Murphy propose that task specialization increases productivity but is limited by coordination costs. Our proposition suggests that automation allows workers to specialize without incurring coordination costs. This is supported by a field experiment among supermarket cashiers.

Summary: The study demonstrates that there is a curvilinear relationship between diversification of knowledge and collaborators on individual productivity. Moderate diversification is optimal when cognitive attention is low, while high diversification is more beneficial when cognitive attention is high. A combination of moderate collaborator diversification and high collaborative attention is optimal for research productivity.

Summary: Continuous cultivation of rice-wheat cropping system in the Indo-Gangetic Plains of India is facing declining productivity and environmental problems. Diversifying crop rotations, such as maize-potato-wheat and maize-wheat-mung bean, can improve system productivity, profitability, and soil health.

Summary: By using Chinese city-level panel data, this study explores the impact of China's high-speed rail (HSR) connection on technological diversity. The results show that HSR connection leads to a decrease in technological diversity, especially in core cities and cities along the four longest HSR lines. It is suggested that HSR connection promotes technological specialization instead of diversification and spurs intra-industry knowledge spillovers rather than inter-industry knowledge spillovers.

Summary: Cereal, oilseed, and protein (COP) production is important for sustainable development goals (SDGs) in Tunisia. Crop diversity can lead to inefficient resource use, and the COP sector has low productivity levels due to weather conditions. This study used data envelopment analysis (DEA) to assess the relationship between land use patterns and farm efficiency. Specialized COP farms showed higher technical efficiency levels than mixed cropping systems, indicating room for reducing inefficiency.

Summary: This study investigates the impact of product diversification on the performance of large construction firms, finding that the influence of diversification depends significantly on changes in institutional dimensions. Managers can adjust PD strategies based on institutional changes to enhance firm performance.

Summary: This study evaluated the effect of weed management practices in the main crop on the growth, yield, and economics of the rice-ratoon rice cropping system. The results showed that weed infestation reduced crop productivity and energy use efficiency. However, all weed control practices improved system productivity and nutrient uptake.
