Data from: Do lianas shape ant communities in an early successional tropical forest?
Almost half of lowland tropical forests are at various stages of regeneration following deforestation or fragmentation. Changes in tree communities along successional gradients have predictable bottom-up effects on consumers. Liana (woody vine) assemblages also change with succession, but their effects on animal succession remain unexplored. Here we used a large-scale liana removal experiment across a forest successional chronosequence (7-31 years) to determine the importance of lianas to ant community structure. We conducted 1088 surveys of ants foraging on and living in trees using tree trunk baiting and hand collecting techniques at 34 paired forest plots, half of which had all lianas removed. Ant species composition, β-diversity, and species richness were not affected by liana removal; however, ant species co-occurrence (the coexistence of two or more species in a single tree) was more frequent in control plots, where lianas were present, vs. removal plots. Forest stand age had a larger effect on ant community structure than the presence of lianas. Mean ant species richness in a forest plot increased by ca. 10% with increasing forest age across the 31-year chronosequence. Ant surveys from forest >20 years old included more canopy specialists and fewer ground-nesting ant species vs. those from forests <20 years old. Consequently, lianas had a minimal effect on arboreal ant communities in this early-successional forest, where rapidly changing tree community structure was more important to ant species richness and composition.
Do early-successional weeds facilitate or compete with seedlings in forest restoration? Disentangling abiotic vs. biotic factors
<p>Census data for seedlings part of a weed exclusion experiment at Sal del Rey, Texas within a larger field where ~100,000 seedlings were planted in October-November 2018. Records seedling height, vigor (0 - dead, > 0 - alive), branching, and animal damage for 158 individuals of eight species classified by growth habit (fast/slow) and distributed in control and exclusion (mowed) plots across seven censuses.</p>

Predicting pasture and forest landowner intention to create early successional habitat
<p>As human land uses expand across the landscape, the management practices of private landowners are an essential part of effective conservation. Early successional habitats (ESH) and the species that depend on them are a priority in the eastern United States, and efforts to create ESH on private lands has primarily focused on forest landowners and timber harvests. Private pasture lands in a forested landscape present an additional opportunity to create and maintain ESH, yet our understanding of landowner values and attitudes about management strategies in pastures is lacking. To address this, we surveyed private landowners in 5 Virginia counties who own ≥10.1 ha or >610 m elevation (<i>n</i> = 503). Our primary objective was to understand how a variety of factors such as landowner values, past experience with habitat management, and perceived barriers to carrying out habitat management are associated with private landowner intention to carry out 7 ESH management strategies (i.e., reduced mowing, reduced grazing, timber harvests within forest, timber harvests at a field-forest border, prescribed fire, use of machinery, and use of herbicides to control invasive species) for the benefit of wildlife in the next five years. We used boosted regression trees to determine which factors best predicted the intention to carry out each strategy. We were able to effectively predict (accuracy > 75%) landowner intention to engage in open pasture and timber management strategies. Landowner values were not consistent across the different management strategies; landowners likely to reduce mowing or grazing valued ecological aspects of their land (i.e., pollinator habitat water quality) whereas landowners likely to harvest timber valued hunting and revenue. Past experience with wildlife management was the strongest predictor of likelihood to reduce mowing and grazing. Our results suggest that expanding outreach efforts to include pasture management options would engage a broader set of landowners in creation of ESH, especially if such efforts highlighted the benefits to pollinator species, water quality, and enhanced opportunities for hunting and other types of recreation.</p>

The catch in five of the ten forest samples returned zero individuals, and were removed from the analysis.
