Grass Seedling Demography and Sagebrush Steppe Restoration [PDF]

Rangeland Ecology and Management, 2012
Seeding is a key management tool for arid rangeland. In these systems, however, seeded species often fail to establish. A recent study in Wyoming big sagebrush steppe suggested that over 90% of seeded native grass individuals die before seedlings emerged.

The demography of tree species response to climate: seedling recruitment and survival

Ecosphere, 2016
AbstractSeedling recruitment and survival are critical bottlenecks in tree population dynamics and are likely to play central roles in shifts in species distributions under climate change. We use data from the Forest Inventory and Analysis program to quantify the relationships between two key climate variables—mean annual temperature and growing season

Salinity strongly drives the survival, growth, leaf demography, and nutrient partitioning in seedlings of Xylocarpus granatum J. König [PDF]

IForest, 2017
Salinity is increasing in the Sundarbans (Bangladesh) due to sea-level rise and the reduction of fresh water flow. Xylocarpus granatum is one of the most valuable mangrove tree species of the Sundarbans. We conducted a six-month long study to investigate the effect of salinity on the survival, growth, leaf demography, and nutrient partitioning in parts

The importance of individuals of different sizes in the population maintenance of a palm species used by the Fulni-ô Indigenous People in northeast Brazil [PDF]

PeerJ
Factors such as climate, soil characteristics, habitat type, and land management practices can influence the demography of plant populations harvested by Indigenous Peoples and local communities.

How do aboveground and belowground functional traits correlate with the demography of tree seedlings regenerated after landslide disturbances?

Journal of Forest Research
Trait-based plant ecology is commonly used to study plant demography in forests, especially after disturbances. However, how functional traits affect the demography of regenerating seedlings after landslides remains largely unknown. This study conducted a 2-year monitoring of Abies sachalinensis (evergreen species) and Acer mono (deciduous species ...

A seed–seedling conflict for Atriplex polycarpa shrubs competing with exotic grasses and their residual dry matter

Ecosphere, 2021
Native saltbush, Atriplex polycarpa, shrub populations are widely diminished and fragmented in the southern San Joaquin Desert of California due to habitat conversion and invasion by exotic annual grasses of mostly Mediterranean origin.

Population Structure of an African Cycad: Fire May Stimulate the Coning Phenology of Encephalartos lanatus (Zamiaceae) and Also Predispose Its Cones to Damage

Diversity, 2023
Cycads are the most threatened group in the plant kingdom. Fire is identified as one of the major factors heightening cycad extinction risk. However, compared to South American cycads, we know little about how fire negatively affects the demography of ...

Which demographic processes control competitive equilibria? Bayesian calibration of a size‐structured forest population model

Ecology and Evolution, 2023
In forest communities, light competition is a key process for community assembly. Species' differences in seedling and sapling tolerance to shade cast by overstory trees is thought to determine species composition at late‐successional stages.

Do an ecosystem engineer and environmental gradient act independently or in concert to shape juvenile plant communities? Tests with the leaf-cutter ant Atta laevigata in a Neotropical savanna [PDF]

PeerJ, 2018
Background Ecosystem engineers are species that transform habitats in ways that influence other species.While the impacts of many engineers have been well described, our understanding of how their impact varies along environmental gradients remains ...
