“…Non-additive population dynamics, that is, change in spawning biomass, linked to temperature or fishing have been previously described for many species. Cod stocks have been particularly studied in this respect due to the availability of long-term time series (Fauchald, 2010;Frank, Petrie, Fisher, & Leggett, 2011;Scheffer, Carpenter, Foley, Folke, & Walker, 2001;Sguotti et al, 2019;Vasilakopoulos & Marshall, 2015) but these studies did not address the nonlinearity of interaction with another species. The fact that climate condition also affects the species interaction in a nonlinear way has implication for management and in particular for the ecosystem approach to fishery management (FAO, 2008), that takes into account the knowledge and uncertainties about biotic (e.g.…”

Climate change has profound ecological effects, yet our understanding of how trophic interactions among species are affected by climate change is still patchy. The sympatric Atlantic haddock and cod are co‐occurring across the North Atlantic. They compete for food at younger stages and thereafter the former is preyed by the latter. Climate change might affect the interaction and coexistence of these two species. Particularly, the increase in sea temperature (ST) has been shown to affect distribution, population growth and trophic interactions in marine systems. We used 33‐year long time series of haddock and cod abundances estimates from two data sources (acoustic and trawl survey) to analyse the dynamic effect of climate on the coexistence of these two sympatric species in the Arcto‐Boreal Barents Sea. Using a Bayesian state‐space threshold model, we demonstrated that long‐term climate variation, as expressed by changes of ST, affected species demography through different influences on density‐independent processes. The interaction between cod and haddock has shifted in the last two decades due to an increase in ST, altering the equilibrium abundances and the dynamics of the system. During warm years (ST over ca. 4°C), the increase in the cod abundance negatively affected haddock abundance while it did not during cold years. This change in interactions therefore changed the equilibrium population size with a higher population size during warm years. Our analyses show that long‐term climate change in the Arcto‐Boreal system can generate differences in the equilibrium conditions of species assemblages.

“…Ending food insecurity and malnutrition through eco-friendly means of agriculture production is a persistent worldwide priority [ 1 , 2 ]. The present worldwide strategy for prevailing food, nutrition, and eco-friendly production has not been able to sufficiently address the global challenges to ensure development toward food and environmental security [ 3 , 4 ]. Innovative high-impact food technologies, such as genetically modified food (hereafter GMF) and biotechnology, now provide prospects for enhancing food production and increasing food quality and nutritional value [ 5 ].…”

“…Regardless of GMFs’ nutritional values and environmental benefits, the literature affirms the large controversies attached to GMF, based on perceived risks and limited public knowledge [ 1 , 3 ]. With the advent of scientific innovations, the global food industry has adopted the newly innovated food generics to address issues of food sovereignty and security [ 1 , 2 ].…”

Owing to the emerging challenges on global food security and the decade of controversies over genetically modified food (hereafter GMF), the present study aims to explore the effects of advertisement framing on health and environmental benefits, sources of perceived risk reduction, and domain-specific knowledge on the acceptance of GMF. The study conducted a quasi-experimental factorial 2 (advertisement message framing: health vs. environmental benefits) × 2 (expert endorsement: present vs. absent) between-subject design involving 300 adult participants from Pakistan. Using a multi-group structural equation model, the four conditions were assigned to each participant group (n = 75) to test the hypothesized relationships. The quasi-experiment results suggested that the advertisement messages (ad-framed) incorporated with the health and environmental benefits, as delineated by experts, can be a viable communication strategy in developing effortless cognitive cues towards GMF acceptance. The pioneer findings validate the significant efficacy of advertisement messages (ad-framed with expert opinions) in reducing perceived risk through augmented objective knowledge that activates the mechanism of favorable development of attitude and acceptance of GMF. The study findings offer strategic directions to policymakers, marketers, and food technologists in raising greater awareness and acceptance towards GMF products.

“…Developments in plant genomics (Brunner et al, 2007a;Neale and Kremer, 2011) have already disclosed the genetic basis of various useful traits (Khan and Korban, 2012;Tuskan et al, 2018). Yet, this information has limitedly been utilized in tree improvement and conservation (Flanagan et al, 2018), despite genetic gains (Figure 1) and optimized management are urgently required due to environmental issues (Scherer et al, 2020). Besides, breeding woody perennials is primarily bottlenecked by their outcrossing reproductive systems, prolonged juvenile phases (Grattapaglia et al, 2018), large genome sizes lacking elimination mechanisms of long-terminal transposons (Nystedt et al, 2013), and an excessive focus on productivity (Burdon and KlápšTě, 2019) that omits adaptive traits ( Table 1; Li et al, 2019).…”

Modern Strategies to Assess and Breed Forest Tree Adaptation to Changing Climate

Studying the genetics of adaptation to new environments in ecologically and industrially important tree species is currently a major research line in the fields of plant science and genetic improvement for tolerance to abiotic stress. Specifically, exploring the genomic basis of local adaptation is imperative for assessing the conditions under which trees will successfully adapt in situ to global climate change. However, this knowledge has scarcely been used in conservation and forest tree improvement because woody perennials face major research limitations such as their outcrossing reproductive systems, long juvenile phase, and huge genome sizes. Therefore, in this review we discuss predictive genomic approaches that promise increasing adaptive selection accuracy and shortening generation intervals. They may also assist the detection of novel allelic variants from tree germplasm, and disclose the genomic potential of adaptation to different environments. For instance, natural populations of tree species invite using tools from the population genomics field to study the signatures of local adaptation. Conventional genetic markers and whole genome sequencing both help identifying genes and markers that diverge between local populations more than expected under neutrality, and that exhibit unique signatures of diversity indicative of "selective sweeps." Ultimately, these efforts inform the conservation and breeding status capable of pivoting forest health, ecosystem services, and sustainable production. Key long-term perspectives include understanding how trees' phylogeographic history may affect the adaptive relevant genetic variation available for adaptation to environmental change. Encouraging "big data" approaches (machine learning-ML) capable of comprehensively merging heterogeneous genomic and ecological datasets is becoming imperative, too.
