The relationship between the concepts of sustainable development and ecological theory has become two issues increasing importance on a global scale (Majeed & Abaas, 2023; Liang Li, 2020; Ruggerio, 2021). Goals such as adaptation to environmental factors, social welfare, economic growth, protection natural resources are considered stages realized in (Alves et al., 2022; Gui-rui 2022). present study purposes. first purpose is contribute literature by examining studies discussing within scope international literature. second identify gaps field reveal academic trends over years, through visual network maps, performing bibliometric analysis with quantitative data both theory.

Eco-evolutionary dynamics in two-species mutualistic systems: One-sided population decline triggers joint interaction disinvestment

Abstract The interplay between ecological and evolutionary dynamics can create feedback that reinforces external disturbances potentially threatens species’ coexistence. For example, plants might invest less into attracting insect pollinators (decreased flower or nectar production) more independence (increased selfing vegetative reproduction) when faced with pollinator decline. This adaptive response saves plant resources at the cost of further threatening population. We ask under which conditions such self-reinforcing occurs in two-species mutualistic systems considering one-sided population decline whether it be counteracted by self-dampening if co-evolution both interaction partners is considered. Based on a mathematical model line previous studies, we find described pattern accelerated for wide range parameter values concave allocation trade-off independent growth investment assumed. undisturbed typically disinvests first, then forces declining to also disinvest, favour other energy sources. However, decelerated occur adaptation partner relatively slow compared environmental decay, reducing speed its disinvestment, initial was very high. Our results suggest actions are taken save endangered populations, not only evolution target species but their partner, as well them should

“Therefore, we attempt to treat the same problem with several alternative models each different simplifications but a common biological assumption.… Hence our truth is intersection of independent lies.” (Levins 1966). Mutualisms are bidirectional, beneficial interspecific interactions ubiquitous across taxa (Bronstein 2015). They contribute significantly ecosystem function and nutrient cycling. For instance, ~40% global food crops dependent on mutualist partner for pollination (Klein et al. 2007). Microbial mutualists, in particular mycorrhizal fungi nitrogen-fixing bacteria, responsible ~75% annual plant phosphorus uptake significant fraction nitrogen as well (van der Heijden 2008). To better understand these interactions, require an overarching theoretical framework. This because empirical results easily confounded by system-specific differences timescale issues, noise ecological data. Developing theory mutualisms beset challenges. First, highly diverse currency benefits they exchange. In plant–microbe mutualisms, exchanged usually nutritional resources (carbon phosphorus, or carbon nitrogen) (Hacskaylo 1972, Oldroyd 2011). plant–pollinator however, pollinators obtain form nectar plants facilitating increased movement pollen (Pellmyr 1996, Pellmyr 2003). The diversity forms makes it challenging develop mutualism population dynamics that can apply interaction types. Further, often temporally dynamic which between species mediated trait evolution. sanction how much provide rhizobia nodules based receives from bacteria (Denison 2000, West 2002). Similarly, evolve abort fruits have been parasitized larvae pollinators, preventing exploitation (Janzen 1979, James 1994). both cases, evolution plays vital role stabilizing mutualistic dynamics. Thus, integrating evolutionary trajectories second challenge address enhance understanding mutualisms. Finally, into whole community ecology framework includes other such predation, parasitism, competition also ongoing goal theory. order challenges, not sufficient build using studies. Mathematical serve perfect tool explore aspects complex interactions. Much like systems, modeling frameworks may be useful addressing kinds questions about mutualism. network track structure pairwise including study disturbances propagate functions emerge species-rich communities (May Valdovinos 2016, Hale 2020).

AbstractAgricultural pests are increasingly appreciated as subjects of ecology. One particular case, a pest in coffee production, is analyzed here using the conceptual framework complex systems, acknowledged having an obvious home field ecology, notorious for its structures. The case arguably falls under control complexity ecological system rather than simple magic bullet population regulation. system, which has been study southern Mexico past quarter century, through lens neutral oscillations classical nondissipative Lotka-Volterra system. Based on three consumer/resource pairs (populations [1] ant, [2] scale insect, [3] beetle predator [4] fungal pathogen and [5] fly parasitoid ant), this five-dimensional well known qualitatively. Coupling all agents both direct effects trait-mediated indirect effects, behavior oscillation form reveals set behaviors, including harmonized invariant sets, chaos, and/or quasiperiodicity. Such behaviors well-known science systems and, it argued, ultimately sufficient to effect degree regulation pest, independent explicit density-dependent feedback.
