Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

Agricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Effects of Restoration on Community Biomass and Its Allocation in a Patchy Alpine Meadow

Grasses
The degradation of alpine meadows on the Qinghai–Tibet Plateau has seriously affected the structure and productivity of grassland communities. In this experiment, a sample area was set up in Keqihetan of Zexiong Village, Youganning Town, Henan County ...

Grazing as a mediator for maintenance of offspring diversity: Sexual and clonal recruitment in alpine grassland communities

, 2011
To understand the effects of grazing on grassland plants sexual and clonal recruitment, we conducted a demographic field investigation of species recruitment along a grazing gradient in the Tibetan alpine grassland.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Protected areas and hunting system affect the survival and longevity of adult female Eurasian lynx in a source–sink population

Conservation Science and Practice, EarlyView.
Variation in cumulative survival time of adult female lynx across (a) area protection categories (UL—Unprotected Landscapes, PLA—Protected Landscape Areas, NP—National Parks) and (b) hunting system categories (NO—No Hunting, NPH—NP Hunting, SFH—State Forests Hunting, PFH—Private Forests Hunting, SFRH—State Forests Rented Hunting, SFO—Small Forest ...

Food System Change, Development, and Vulnerability in Semi‐Agricultural Areas of Tibet

Culture, Agriculture, Food and Environment, EarlyView.
ABSTRACT With social and economic development, food systems have significantly changed on the Tibetan plateau over the last two decades. However, the impact of dietary change on Tibetans and their communities remains less well known. This article examines how food change happens in semi‐agricultural areas of eastern Tibet within the context of ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

Ecological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

A review on true dung beetles' evolutionary and ecological responses to temperature and impacts on ecosystem functions

Ecological Entomology, EarlyView.
True dung beetles are a speciose group of ecosystem engineers that play key roles as detritivores in natural and agricultural landscapes. Scarabaeine beetles show strong thermal plasticity and there is increasing evidence of rapid evolutionary divergence in response to temperature across ecological and evolutionary timescales, with likely consequences ...

Structure and Function of the Central Himalayan Alpine Grassland, India [PDF]

Extensive alpine and sub-alpine pastures occur in Central Himalaya (28-31° N lat. and 79-81° E long.) at 3.000-4.500 rn. There is a notable lack of quantitative information on high mountain grasslands in India.
