| The northern New Mexico thinning-and-prescribed-burning treatments had less impact on beetle communities than clear-cutting or high-severity wildfire, according to the study. | COMPARATIVE | Leans supported |
| The northern New Mexico restoration treatments were associated with 21 common beetle species increasing and 35 declining in the post-treatment sub-canopy environment. | QUANTITATIVE | Supported |
| In a six-year northern New Mexico mixed-conifer case study, thinning followed by prescribed broadcast burning significantly changed surface-active beetle community composition. | OBSERVATIONAL | Supported |

| The study consolidated 58,319 outbreak-event records covering 32 emerging infectious diseases to test social and environmental drivers of outbreak geography. | QUANTITATIVE | Supported |
| In the study, fractal dimension 2.41 and height range 7.96 cm produced oyster densities 35% higher than the maximum-dimension, 12-cm-height configuration. | QUANTITATIVE | Supported |
| The study found that oyster settlement and survival were greatest at particular combinations of reef fractal dimension and height that minimized predation. | CAUSAL | Supported |
| The study deployed 480 artificial oyster-habitat replicates spanning 16 geometries across three estuaries, with half caged against predation. | QUANTITATIVE | Supported |
| In the study's analysis, bear conflict is further amplified when an alternative food source fails in the same period as mast production. | CAUSAL | Leans supported |
| In the five-Tohoku-prefecture dataset, bear conflict rises sharply when mast production falls below a threshold. | CAUSAL | Leans supported |
| The reported associations between ancient Maya features and modern forest structure were strongest at spatial scales of approximately 100 to 300 metres, and their wider geographic extent remains untested. | QUANTITATIVE | Supported |
| In the studied old-growth forest of northern Belize, ancient Maya wetland fields, settlements, and upland walls were each associated with distinct modern forest-structure metrics. | COMPARATIVE | Supported |
| The study analyzed microbial genomes reconstructed from 820 reef-building coral samples collected at 99 Pacific reefs across 32 islands. | QUANTITATIVE | Supported |
| In the study population, most Gasterosteus nipponicus genomic material was purged within ten generations after the tsunami. | QUANTITATIVE | Supported |
| The study reported early purging of Gasterosteus nipponicus alleles at reproductive-isolation loci, followed by broader genome-wide purging except at several loci. | OBSERVATIONAL | Supported |
| The study used nine years of genomic monitoring to examine a tsunami-induced hybrid stickleback population and its post-hybridization allele changes. | HISTORICAL | Supported |
| The Hindu Kush Heremites lineage was estimated to have split from related western clades in the Late Miocene approximately 10 million years ago and is currently known from two southern-Hindu-Kush foothill localities. | QUANTITATIVE | Supported |
| Mitochondrial, nuclear, phylogenetic, and morphological evidence supported recognizing the Hindu Kush lineage of Heremites as a distinct new species. | COMPARATIVE | Supported |
| The study’s climate-space analysis found that the regional tree flora was progressively filtered toward colder and drier conditions, alongside losses of heat-tolerant lineages. | OBSERVATIONAL | Supported |
| In the study’s fossil synthesis, Western and Central European tree-genus richness declined 75% from its Miocene peak to the Holocene. | QUANTITATIVE | Supported |
| The study compiled 711 fossil occurrences representing tree genera from Western and Central Europe across the Cenozoic. | QUANTITATIVE | Supported |
| In a seven-year biomonitoring study of 1,003 Barred Owls in northwestern California, second-generation anticoagulant exposure among young owls fell from about 50% in 2019 to about 20% in 2024, while vitamin D3 rodenticide was detected in 18.5% overall and all rodenticides in up to 46%. | QUANTITATIVE | Supported |
| Gap soils had more densely connected but topologically simplified microbial co-occurrence networks with fewer keystone taxa, and predicted functional potential was associated with both keystone structure and whole-community structure rather than keystone structure alone. | COMPARATIVE | Supported |
| Soil bacterial temporal turnover and seasonal community divergence were greater in forest gaps than in adjacent closed-canopy soils in a subtropical karst forest. | COMPARATIVE | Supported |
| Within marine ecosystems, species asynchrony was the strongest predictor of fish-mediated nutrient-dynamics stability, with higher synchrony associated with destabilization. | COMPARATIVE | Supported |
| Across coral reef, mangrove, seagrass, and kelp ecosystems, fish species richness positively predicted the temporal stability of consumer-mediated nutrient dynamics measured as nitrogen supply via excretion. | COMPARATIVE | Supported |
| Across 357 Minnesota lakes, zebra mussel establishment was associated with increased mercury in harvestable-sized fish of four of six species, with species-specific increases of 6% to 21% and higher threshold exceedance risk in some fish. | QUANTITATIVE | Supported |
| The moss carder bumblebee showed a 2.86-fold increase in runs of homozygosity in England and Wales over the museum-sampled period, where habitat fragmentation was most pronounced. | QUANTITATIVE | Supported |
| Whole-genome data from 101 museum specimens indicate an approximately 24.6% reduction in genome-wide heterozygosity in the moss carder bumblebee across Britain between 1894 and 2019. | QUANTITATIVE | Supported |
| The global synthesis found that crop diversification indirectly promotes crop production through suppression of pests. | CAUSAL | Leans supported |
| A global synthesis of 609 studies found that increasing plant species consistently promotes plant performance and suppresses antagonist performance across agro-ecosystems, grasslands and forests. | QUANTITATIVE | Supported |
| In the first few generations after tsunami-induced hybridization, Gasterosteus nipponicus alleles were purged at major loci associated with reproductive isolation, including ancestral-X and neo-X chromosomes. | OBSERVATIONAL | Supported |
| Nine-year genomic monitoring of a tsunami-induced hybrid stickleback population in Japan found rapid genome-wide purging within a few generations, with marine Gasterosteus nipponicus alleles subsequently purged across the genome except at several loci. | OBSERVATIONAL | Supported |
| Colonists absent at the start of a time series compensated for losses within the rarest abundance category in the synthesis of population trends. | COMPARATIVE | Supported |
| Across 4,748 sites in 129 studies, formerly common species showed consistently stronger population declines than formerly rare species in marine and terrestrial assemblages, while freshwater assemblages showed no clear directional pattern. | COMPARATIVE | Supported |

| After four Klamath River hydroelectric dams were removed in 2024, stationary multi-beam imaging SONAR estimated 7,742 adult Chinook salmon migrated upstream in 2024 and 13,310 in 2025, with the stated 95% confidence intervals. | QUANTITATIVE | Supported |
