Enhancing Farm Dams Increases Tadpole Abundance.

Understanding how agricultural and land management practices affect amphibian biodiversity is essential for conservation efforts in farmland. We investigated the impact of farm dam enhancement on tadpole abundance and growth in a highly modified farming landscape in south-eastern Australia. We completed detailed surveys on 52 farm dams (artificial ponds or agricultural reservoirs).

Multiple Long-Term, Landscape-Scale Data Sets Reveal Intraspecific Spatial Variation in Temporal Trends for Bird Species.

Quantifying temporal changes in species occurrence has been a key part of ecology since its inception. We quantified multidecadal site occupancy trajectories for 18 bird species in four independent long-term, large-scale studies (571 sites, ~1000 km latitude) in Australia. We found evidence of a year × long-term study interaction in the best-fitting models for 14 of the 18 species analysed, with differences in the temporal trajectories of the same species in multiple studies consistent with non-stationarity.

A widely employed water supply catchment model and other empirical insights suggest that logging may contribute to lower water yields.

In an earlier study published in Science of the Total Environment (Taylor et al., 2019), we used an established hydrological model (based on what is known as the Kuzcera curve), to analyse the impacts of logging on water yields in a major watershed - the Thomson water supply catchment - in the Central Highlands of Victoria, south-eastern Australia. We demonstrated that under some plausible climate change projections, the impacts of logging on catchment water yields may exceed those resulting from climate change (Taylor et al.

Indirect and direct drivers of floristic condition in a threatened temperate woodland.

Almost half of Earth's surface is threatened by agriculture, which has extensively degraded ecosystems and resulted in significant biodiversity loss. Remnant ecosystems in fragmented agricultural landscapes are threatened by past and present grazing and land-clearing. Declines in native diversity are common in these ecosystems, and their restoration is a key conservation goal globally.

A misleading tail: A long-term study of reptile responses to multiple disturbances undermined by a change in surveying techniques.

Long-term ecological monitoring is crucial to understanding the complex dynamics of ecosystems, communities, and populations. Despite this, monitoring data are lacking or rare for the vast majority of biodiversity. Here we report the results of 19 years (2003-2022) of continuous annual monitoring of reptile species at Booderee National Park (BNP) on the east coast of south-eastern Australia.

The ecological and biodiversity conservation values of farm dams: A systematic review.

Biodiversity is in rapid decline globally with agriculture being one of the leading causes. Within agricultural landscapes, some features provide a benefit to biodiversity that is disproportionate to their spatial area. An interesting example is artificial ponds-or farm dams-which can support a large variety of taxa.

Identifying and managing disturbance-stimulated flammability in woody ecosystems.

Many forest types globally have been subject to an increase in the frequency of, and area burnt by, high-severity wildfire. Here we explore the role that previous disturbance has played in increasing the extent and severity of subsequent forest fires. We summarise evidence documenting and explaining the mechanisms underpinning a pulse of flammability that may follow disturbances such as fire, logging, clearing or windthrow (a process we term disturbance-stimulated flammability).

Biodiversity market doublespeak.

The notion that biodiversity markets can raise money desperately needed for biodiversity conservation is gaining momentum. The dire state of biodiversity and the enormous biodiversity repair bill means that every funding option must be explored. However, the risk that trading ill-defined generic biodiversity credits will result in biodiversity loss, not conservation, should be considered.

Size-focused conservation may fail to protect the world's oldest trees.

Old trees are irreplaceable natural resources that provide multifaceted benefits to humans. Current conservation strategies focus primarily on large-sized trees that were often considered old. However, some studies have demonstrated that small trees can be more than thousands of years old, suggesting that conventional size-focused perceptions may hamper the efficiency of current conservation strategies for old trees.

Temporal trends in reptile occurrence among temperate old-growth, regrowth and replanted woodlands.

Reptiles are an important part of the vertebrate fauna in the temperate woodlands of south-eastern Australia. However, compared to birds and mammals, the long-term occurrence of reptiles across woodland growth types-old growth, regrowth, and replantings-remains poorly understood. Here, using 18-years of data gathered at 218 sites across 1.

Temporal dynamics of soil fungi in a pyrodiverse dry-sclerophyll forest.

Fire is a major evolutionary and ecological driver that shapes biodiversity in forests. While above-ground community responses to fire have been well-documented, those below-ground are much less understood. However, below-ground communities, including fungi, play key roles in forests and facilitate the recovery of other organisms after fire.

Who will name new plant species? Temporal change in the origins of taxonomists in China.

Discovery rates of new plant species need to be accelerated because many species will be extinct before they are formally described. Current studies have focused on where new species may occur and their characteristics. However, who will actually discover and describe these new species has received limited attention.

Increases in intraspecific body size variation are common among North American mammals and birds between 1880 and 2020.

Many studies have documented the average body size of animals declining over time. Compared to mean body size, less is known about long-term changes in intraspecific trait variation (ITV), which is also important to understanding species' ability to cope with environmental challenges. On the basis of 393,499 specimen records from 380 species collected in North America between 1880 and 2020, we found that body size ITV increased by 9.

Forest restoration in a time of fire: perspectives from tall, wet eucalypt forests subject to stand-replacing wildfires.

Wildfires have the potential to add considerably to the already significant challenge of achieving effective forest restoration in the UN Decade on Ecosystem Restoration. While fire can sometimes promote forest restoration (e.g.

Eight things you should never do in a monitoring program: an Australian perspective.

Monitoring is critical to gauge the effect of environmental management interventions as well as to measure the effects of human disturbances such as climate change. Recognition of the critical need for monitoring means that, at irregular intervals, recommendations are made for new government-instigated programs or to revamp existing ones. Using insights from past well-intentioned (but sadly also often failed) attempts to establish and maintain government-instigated monitoring programs in Australia, we outline eight things that should never be done in environmental monitoring programs (if they aim to be useful).
