“…While net energy income is a universal currency determining the success of foraging strategies across all disperser clades, disperser's responses to fruit shape and color will depend on the cognitive and learning ability of dispersers in associating these traits with fruit quality (Nevo et al 2018). Commonly, endozoochoric plants are visited by a diverse set of frugivore species such as lizards (Valido & Olesen 2019), birds (Howe 1987), bats (Charles-Dominique & Cockle 2001), rodents (Godo et al 2022), and other mammals (Matias et al 2010), that largely vary in their learning and cognitive abilities. Therefore, PL may affect the quantitative SDE component if it results in the formation of misshapen and/or miscolored fruits, but this effect should largely depend on the type of seed dispersers available and their cognitive abilities (Healy & Jones 2002;Duan et al 2015) (Table 01).…”

Seed production and dispersal are crucial ecological processes impacting plant demography, species distributions, and community assembly. Plant-animal interactions commonly mediate both seed production and seed dispersal, but current research often examines pollination and seed dispersal separately, which hinders our understanding of how pollination services affect downstream dispersal services. To fill this gap, we propose a conceptual framework exploring how pollen limitation can impact the effectiveness of seed dispersal for endozoochorous and myrmecochorous plant species. We summarize the quantitative and qualitative effects of pollen limitation on plant reproduction and use Optimal Foraging Theory to predict its impact on the foraging behavior of seed dispersers. In doing so, we offer a new framework that poses numerous hypotheses and empirical tests to investigate downstream effects of pollen limitation on seed dispersal effectiveness and, consequently, post-dispersal ecological processes occurring at different levels of biological organization. Finally, considering the importance of pollination and seed dispersal outcomes to plant eco-evolutionary dynamics, we discussed the implications of our framework for future studies exploring the demographic and evolutionary impacts of pollen limitation for animal-dispersed plants.

“…Burrowing mammals are referred to as ‘ecosystem engineers’ (Davidson et al, 2010; Prugh & Brashares, 2012; Reichman & Seabloom, 2002; Zhang et al, 2003), because burrowing mammals can increase plant diversity by increasing species turnover, seed dispersion, light availability by consuming taller grasses, soil nutrient heterogeneity by digging and by creating germination spaces (Godó et al, 2022; Mallen‐Cooper et al, 2019; Olff & Ritchie, 1998; Root‐Bernstein & Ebensperger, 2013) (Figure 2). Small mammal burrows also provide refuges and habitats that increase the abundance and diversity of birds, amphibians, reptiles, insects and spiders (Prugh & Brashares, 2012; Smith & Foggin, 1999).…”

Over the last 40 years, a burrowing mammal eradication policy has been prevalent on the Qinghai–Tibetan Plateau (QTP). This policy is based on similar burrowing mammal eradication programs in other areas and is justified on the assumptions that burrowing mammals compete with livestock for forage and contribute to grassland degradation. However, there is no clear theoretical or experimental evidence supporting these assumptions. This paper synthesizes the ecological functioning of small burrowing mammals in natural grasslands and discusses the irrationality and consequences of burrowing mammal eradication for sustainable livestock grazing and grassland degradation. Past burrowing mammal eradication efforts have failed because increased food availability for the remaining rodents and reduced predator populations led to rapid population rebounds. Herbivores differ in diet, and there is clear evidence that burrowing mammals, especially plateau zokors Myospalax baileyi, have a different diet than livestock. In QTP meadows, burrowing mammal eradication induces a shift towards plant communities with fewer species preferred by livestock and more species preferred by burrowing mammals. Thus, eradicating burrowing mammals has the opposite effect, a reduction in livestock preferred vegetation. We suggest that the policy of poisoning burrowing mammals needs to be reconsidered and revoked as soon as possible. We argue that incorporating density‐dependent factors such as predation and food availability are essential for maintaining a low burrowing mammal density. For degraded grasslands, we suggest that the optimal sustainable approach is to decrease the intensity of livestock grazing. Lower grazing induces changes in vegetation structure and plant species composition that increases predation on burrowing mammals and decreases the abundance of plants preferred by burrowing mammals. Such a nature‐based grassland management system maintains the density of burrowing mammals at a low stable density while minimizing human management and interventions.
