Environment Development and Sustainability, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 4, 2024

Abstract Food security remains a pressing concern in the face of an increasing world population and environmental challenges. As climate change, biodiversity loss, water scarcity continue to impact agricultural productivity, traditional livestock farming faces limitations meeting growing global demand for meat dairy products. In this context, black soldier fly larvae (BSFL) have emerged as promising alternative sustainable food production. BSFL possess several advantages over conventional livestock, including their rapid growth, adaptability various organic waste substrates, low impact. Their bioconversion rate, ability transform into valuable products, final product optimization are key factors that enhance potential nutrient-rich protein source, fertilizer, biofuel. This review explores strategies rate improve end products derived from BSF treatment. It highlights benefits using other interventions underscores significance optimizing meet challenges sustainably. Despite prospects BSF-derived consumer acceptance regulatory hurdles remain critical aspects address realizing full market potential. The utilization source feed can contribute management, reduce pollution, issue environmentally responsible manner. However, there is need further research innovation ensure safety, quality, economic viability BSF-based both animal human consumption.

Reviving Europe's rivers: Seven challenges in the implementation of the Nature Restoration Law to restore free‐flowing rivers

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(3)

Published: Jan. 30, 2024

Abstract The EU Nature Restoration Law represents an important opportunity for freshwater habitat restoration and, consequently, biodiversity protection. However, a number of challenges must be anticipated in its implementation, which may compromise success. Some aspects, particularly those relating to ecosystems, require more clarification. We use riverine ecosystems illustrate existing ambiguities the proposed legislation and potential consequences leaving these aspects open interpretation during implementation process. also discuss solutions problems could help ensure that law's objectives are met. argue river network structure connectivity dimensions, result into meta‐ecosystems, explicitly considered. For purpose, we ask clear definitions critical terms “free‐flowing rivers,” “barriers,” “reference areas.” In addition, recommend developing methods integrated assessment across networks. As key property this used prioritize actions increase length free‐flowing rivers. Adequate planning at larger spatial scales will benefit from meta‐ecosystem perspective accurate representation aquatic‐terrestrial linkages, significantly improve efficacy efforts. Furthermore, stakeholder citizen engagement offer opportunities local, national, European scales, should fostered inclusive decision‐making. conservation outlined here rivers, but they have implications other ecosystems. These considerations useful policymakers, conservationists, stakeholders involved related policy initiatives.

Addressing grand ecological challenges in aquatic ecosystems: how can mesocosms be used to advance solutions?

Oikos, Journal Year: 2025, Volume and Issue: unknown

Rapid and drastic anthropogenic impacts are affecting global biogeochemical processes driving biodiversity loss across Earth's ecosystems. In aquatic ecosystems, species distributions shifting, abundances of many have declined dramatically, threatened with extinction. addition to diversity, the ecosystem functions, services on which humans depend also being heavily impacted. Addressing these challenges not only requires direct action mitigate environmental but innovative approaches identify, quantify treat their effects in environment. Mesocosms valuable tools for achieving goals as they provide controlled environments evaluating stressors testing novel mitigation measures at multiple levels biological organisation. Here, we summarise discussions from a survey marine freshwater researchers who use mesocosm systems synthesise opportunities limitations advancing solutions grand ecological While most research utilising ecology has focused quantifying threats, there is largely unexplored potential using them test solutions. To overcome spatio‐temporal constraints, scale up size time‐scales studies, or alternatively, outcomes habitat‐scale restoration smaller scale. Enhancing connectivity future studies can help limitation isolation an important aspect recovery. Conducting ‘metacosm' studies: coordinated, distributed experiments spanning wide climatic gradients more regression‐based experimental designs tackle challenge context dependent results.

Environmental Flow Requirements of Estuaries: Providing Resilience to Current and Future Climate and Direct Anthropogenic Changes

Frontiers in Environmental Science, Journal Year: 2021, Volume and Issue: 9

Published: Nov. 17, 2021

Estuaries host unique biodiversity and deliver a range of ecosystem services at the interface between catchment ocean. They are also among most degraded ecosystems on Earth. Freshwater flow regimes drive ecological processes contributing to their economic value, but have been modified extensively in many systems by upstream water use. Knowledge freshwater requirements for estuaries (environmental flows or E-flows) lags behind that rivers floodplains. Generalising estuarine E-flows is further complicated responses appear be specific each system. Here we critically review E-flow 1) identify key (hydrodynamics, salinity regulation, sediment dynamics, nutrient cycling trophic transfer, connectivity) modulated regimes, 2) drivers (rainfall, runoff, temperature, sea level rise direct anthropogenic) generate changes magnitude, quality timing flows, 3) propose mitigation strategies (e.g., modification dam operations habitat restoration) buffer against risks altered build resilience indirect anthropogenic disturbances. These support re-establishment natural characteristics which foundational healthy ecosystems.

Regional-scale ecological processes, such as the spatial flows of material, energy, and organisms, are fundamental for maintaining biodiversity ecosystem functioning in river networks. Yet these processes remain largely overlooked most management practices underlying policies. Here, we propose adoption a meta-system approach, where regional acting at different levels organization - populations, communities, ecosystems integrated into conventional conservation, restoration, biomonitoring.

In this review, we highlight advancements current environmental studies investigating interactive effects between contaminants freshwater marine invertebrates. We not only focused on temperate regions also synthesized information less studied Arctic/Antarctic tropical regions. Recent Findings general, same combination may result either additive or non-additive depending taxa, response variable, life stage, genotype, exposure level, duration order exposure, number exposed generations. For traditional such as metals pesticides, combined with at individual level were generally synergistic. Growing evidence suggests that multigenerational can shift interaction toward antagonism, while contemporary evolution change type. Summary Our synthesis highlights importance temporal aspects shaping type, including ontogenetic effects, transgenerational evolution.

Revisiting the growth rate hypothesis: Towards a holistic stoichiometric understanding of growth

Ecology Letters, Journal Year: 2022, Volume and Issue: 25(10), P. 2324 - 2339

Published: Sept. 11, 2022

The growth rate hypothesis (GRH) posits that variation in organismal stoichiometry (C:P and N:P ratios) is driven by growth-dependent allocation of P to ribosomal RNA. GRH has found broad but not uniform support studies across diverse biota habitats. We synthesise information on how why the tripartite growth-RNA-P relationship predicted may be uncoupled outline paths for both theoretical empirical work needed broaden working domain GRH. strong RNA (r2 = 0.59) RNA-P 0.63) relationships taxa, were relatively weaker 0.09). Together, was supported ~50% studies. Mechanisms behind uncoupling could generally attributed physiological (P accumulation non-RNA pools, inactive ribosomes, translation elongation rates protein turnover rates), ecological (limitation resources other than P), evolutionary (adaptation different nutrient supply regimes) causes. These factors should accounted tests formalised mathematically facilitate a predictive understanding growth.
