Host specificity, which reflects the number of hosts a parasite can infect, is a key concept in disease ecology due to its connection with zoonotic parasites. This study assessed the specificity of metazoan parasites in marine and freshwater fish from Peru using indices such as STD, VarSTD, STD*, and βSPF. The results showed that parasites like Lecithocladium cristatum and Helicometra fasciata have low specificity (STD ≈ 5), whereas Procamallanus (Spirocamallanus) pintoi, Proleptus carvajali, and Lernanthropus huamani exhibit high specificity. The lack of correlation between the number of hosts and the indices indicates that specificity depends more on adaptation to the host than on the number of infected species.This study, the first to apply IHS indices for aquatic parasites in Peru, lays the groundwork for future research and underscores their ecological importance.

The highest demand for ecosystem services for human activities around the world, come from the coastal marine zone (CMZ). In areas with poor management, this can have consequences in the loss of the environments and ecosystem services. The aim of the study was to develop scenarios for the management proposal for the coastal marine zone (CMZ) between Pacocha (Moquegua) and Morro Sama (Tacna) in Peru. The study area extended five kilometers inland from the coastline and encompassed a marine zone stretching five miles offshore. The development of the management proposal was based on the identification and mapping of the area's ecosystems, the ecosystem services they provide, and the pressures exerted on them by human activities.

To develop the management proposal, the Marxan with Zones program was utilized. The model incorporated the identified ecosystems, ecosystem services, ecosystem pressures, and the presence of natural mollusc banks and rivers. The modeling process resulted in the implementation of four management zones: Protection, Preservation, Sustainable Use, and Recovery. The Sustainable Use zone was the largest, covering 30% of the total area, while the Recovery zone was the smallest, occupying 16%. These results can serve as a valuable tool for decision-makers in implementing an Integrated CMZ plan.

The purpose of this study is to evaluate the dynamics of vegetation cover using NDVI in the Condebamba Valley, Cajamarca, between 2003 and 2024. The results record variations in vegetation cover: the maximum NDVI has increased, reflecting improvements in certain areas due to plant conservation and regeneration strategies, while the minimum NDVI has decreased significantly, indicating greater soil degradation due to deforestation, urbanization, mining and the reduction of water resources as a result of climate change. The average NDVI went from 0.245 in 2003 to 0.257 in 2024, showing loss of vegetation. In 2024, the maximum NDVI reached 0.615 and the minimum was recorded in 2028 (- 0.131) and then dropped to -0.102 in 2024, reflecting a fragmentation of the natural landscape with a slow recovery of vegetation cover. Although some areas show signs of restoration, other areas continue to deteriorate. Urban expansion, changes in land use, the existence of mining in the area and climate change have influenced this process. It is recommended to strengthen conservation and reforestation strategies to mitigate these effects.

Coral reefs, essential for marine biodiversity, face threats such as pollution, climate change and natural phenomena. This paper analyzes water quality in Tela Bay, Atlántida, Honduras, where Capiro Reef is located. For this purpose, sampling was carried out in three zones (A, B and C) to evaluate water quality at different distances from the coast. The parameters evaluated included: pH, total nitrogen, total phosphorus, dissolved oxygen, turbidity, chemical oxygen demand and fecal coliforms. The results indicated that point A, near the Lancetilla River, has a marginal quality index of 63.1, i.e., frequent deterioration. At points further away (B and C), the index improves slightly, but still reveals the presence of contaminants, such as nitrogen and chemical oxygen demand, which exceed the established limits. The analysis details how factors such as the presence of excessive nutrients, pathogens and ocean acidification negatively affect the health of these ecosystems.

The turnover of technology personnel is becoming increasingly common in organizations, impacting various aspects such as the loss of specialized knowledge, job dissatisfaction, and hidden costs. This study analyzes the factors that motivate Generation Z, who have recently entered the labor market, within the IT department of a company in Buenos Aires, Argentina. The research is descriptive and based on an empirical case study, aiming to identify key motivational factors to develop effective strategies for talent acquisition and retention, thereby preventing a loss of competitiveness. The results highlight the importance of salary, recognition and professional development, work environment, flexibility, and the balance between personal and professional life as the main motivational factors for generation Z.

Abstract - This research investigates the design and manufacture of non-pneumatic tires (NPTs) utilizing additive manufacturing (AM) techniques for human-powered vehicles (HPVs) operating in challenging terrains, such as those encountered during competitions like NASA’s Human Exploration Rover Challenge (NASA HERC). Traditional pneumatic tires are often susceptible to punctures and require extensive maintenance, rendering them less effective in these demanding environments. In contrast, NPTs provide enhanced puncture resistance and significantly lower maintenance needs, yet their design poses complex challenges concerning load-carrying capacity, traction, and durability. This study leverages the advantages of AM to tackle these challenges, allowing for the creation of intricate geometries and internal structures that can be optimized for specific terrains. Additionally, the research emphasizes the use of flexible materials, particularly thermoplastic polyurethane (TPU), and thoroughly evaluates the influence of various AM processes on the mechanical properties and performance of NPTs. Through rigorous experimental and field-specific testing, our goal is to refine NPT designs, ensuring they meet demanding performance criteria while promoting sustainable manufacturing practices, ultimately contributing to advancements in HPV technology.
