Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Eruptive Conditions and Dentition of the Upper and Lower Deciduous Molars and First Molars during the Early Mixed Dentition Period : Coronal Axial, and Bucco-lingual Surface Inclination [PDF]

open access: yes, 2003
P(論文)To elucidate the eruptive conditions and dentition of the deciduous molars and the first molars during the early mixed dentition period (dental age IIIA), tooth crown and gingival morphology in the dental plaster casts was measured using a three ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Calcium hydroxide-induced resorption of deciduous teeth: A possible explanation

open access: yesDental Hypotheses, 2012
Introduction: Calcium hydroxide (CaH) is customarily used for permanent teeth but not for deciduous dentition because it is known to cause internal resorption in the latter.

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

The impact of herbivores on the natural regeneration of temperate deciduous woodland [PDF]

open access: yes, 1999
Many studies have reported deficient or intermittent patterns of natural regeneration in temperate deciduous woodland. The present study aimed to assess the relative impact of herbivore-mediated plant mortality on the natural regeneration dynamics of ...

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

open access: yesEcography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Wolves and humans both shape patterns of deer browsing in a temperate forest ecosystem of Central Europe

open access: yesEcography, EarlyView.
Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.

Clinical comparison of various esthetic restorative options for coronal build-up of primary anterior teeth

open access: yesDental Research Journal, 2015
Background: This study was designed to compare the clinical performance of composite, strip crowns, biological restoration, and composite with stainless steel band when used for the coronal build-up of anterior teeth.
