ABSTRACT.- Question: Understanding the patterns of alien plant invasions and their underlying drivers is a key step in conserving the remaining native grasslands of Uruguay. We addressed the level of invasion by considering the four invasive alien plants of these ecosystems, Cynodon dactylon, Eragrostis plana, Senecio madagascariensis and Ulex europaeus, throughout the country. Location: Remnant native grasslands of Uruguay, constituting part of the Río de la Plata grasslands.

Hay solo una cosa en que la comunidad científica coincide, que ya está pasando y será peor en el futuro: están habiendo eventos climáticos extremos más frecuentes y más dañinos. Tenemos sequías, inundaciones, olas de calor. Si sigue cambiando el clima, esto será cada vez peor. Tenemos que adaptarnos; pero ¿adaptarnos a qué y cómo?, interpela Walter Baethgen (*).

La selección genética es una herramienta clave para fortalecer la sostenibilidad económica, social y ambiental de la ganadería, con impacto acumulativo y permanente. Actualmente, el sector enfrenta el desafío de reducir las emisiones de metano entérico producido por los rumiantes.

ABSTRACT.- Numerous conservation and regeneration practices are recognized as effective strategies in the management of soil health (SH), a critical factor for ensuring the sustainability of food production systems. Despite their acknowledged importance, the multifaceted impacts of these practices often lead to confounding effects, and reliance on generic categorization of agronomic practices often falls short in portraying the drivers of SH. We advocate for a paradigm shift from a label-centric approach to one rooted in processes.

ABSTRACT.- South American beef production varies due to diverse climates, environmental conditions, animal breeds (Bos indicus, Bos taurus and crossbreeds), management strategies, and nutritional sources. Applying technology in the South American beef production system can significantly enhance efficiency, sustainability, and profitability. Reproductive efficiency is a significant challenge, especially in cow-calf operation systems conducted under adverse conditions. Consequently, implementing effective assisted reproduction technologies (ART) can make a significant contribution.

La pérdida de biodiversidad en el Antropoceno alcanza tasas similares a la última extinción masiva, afectando el ambiente drásticamente. En Uruguay, a fines del siglo XX, el uso del suelo cambió significativamente debido al avance de la forestación y la producción de soja.

ABSTRACT.- The purpose of this work is to describe the creation process of the first long-term experimental platform designed for interdisciplinary studies of Silvopastoral Systems (SPS) in Uruguay and to highlight its relevance on filling knowledge gaps across different areas. This experiment involves professionals from diverse fields working together to generate knowledge for sustainable agriculture. The focus is on understanding long-term interactions in SPS, emphasizing native ecosystem conservation and increased agricultural productivity.
