Seasonal patterns and interannual variability of phytoplankton in Lake Stechlin [PDF]
, 2004 The paper presents results of detailed phytoplankton investigations in Lake Stechlin between 1994 and 2003. The analysis includes the picoplankton fraction (dominated by Cyanobium sp.) that regularly appears as a deep-layer chlorophyll maximum (DCM ...

Restoration Ecology, EarlyView.Abstract Introduction Globally, livestock grazing is a key driver of vegetation degradation in arid rangelands. This degradation tends to be most severe near artificial water points which are focal points for livestock activity. Conservation reserves have been established on former rangelands; however, the timeframes for vegetation recovery following ...

Adopting national vegetation guidelines and the National Vegetation Information System (NVIS) framework in the Northern Territory [PDF]
, 2013 Guidelines and core attributes for site-based vegetation surveying and mapping developed for the Northern Territory, are relevant to botanical research, forestry typing, rangeland monitoring and reporting on the extent and condition of native and non ...

Restoration Ecology, EarlyView.Restoration increasingly operates in rapidly transforming landscapes shaped by human‐driven global change, where historical reference states no longer represent achievable or even desirable targets. Yet, ecological restoration and conservation management still rely on composition‐based definitions of ecosystem integrity that assume stable reference ...

Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Object identification and characterization with hyperspectral imagery to identify structure and function of Natura 2000 habitats [PDF]
, 2010 Habitat monitoring of designated areas under the EU Habitats Directive requires every 6 years information on area, range, structure and function for the protected (Annex I) habitat types.

Horses on the Menu: Patterns and Drivers of Free‐Ranging Horse Consumption by Iberian Wolves
Mammal Review, Volume 56, Issue 2, June 2026.Free‐ranging mountain ponies can comprise most of the Iberian wolf diet. Through a meta‐analysis of 137 studies, we show that horse consumption is shaped by prey availability, topography and human density, often surpassing wild and domestic ungulates and potentially serving as a buffer for livestock predation.

Can species adapt to drought using multiple strategies? Lessons from the California poppy
New Phytologist, Volume 250, Issue 5, Page 2918-2932, June 2026.Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

The Canadian Field-Naturalist, 2013 Coefficients of Conservatism and the Floristic Quality Index can be used to assess potential damage to plants and plant communities as a result of anthropogenic disturbances. This has benefit because it may be more powerful than an opinion and more easily understood and trusted by non-botanists and land use decision-makers.

Ecology and Evolution, Volume 16, Issue 5, May 2026.The first regional survey of spontaneous plant communities across 17 cities on the Qinghai‐Tibet Plateau shows that natural climatic conditions, especially precipitation and wind speed, are the primary drivers of variation in community diversity, while urbanization and habitat quality jointly structure plant community composition.
