Conservation Actions in Multi-Species Systems: Species Interactions and Dispersal Costs

Frontiers in Ecology and Evolution, 2021
We use the General Equilibrium Ecosystem Model (GEEM) parameterized to Wyoming sagebrush to explore the impact of two common simplifications in bio-economic policy frameworks on species conservation decisions.

Attachment sites of generalist ticks on birds depend on environmental factors (habitat and season) rather than on tick species

Ticks and Tick-Borne Diseases
The aim of this investigation was to analyze predilection sites of ticks on avian hosts according to tick species and developmental stages, as well as individual and ecological characters of bird species (i.e., their age, habitat type, seasonality).

Zooplankton biodiversity and community structure vary along spatiotemporal environmental gradients in restored peridunal ponds

Journal of Limnology, 2015
Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the ...

Detecting Critical Scales in Fragmented Landscapes

Ecology and Society, 1997
We develop methods for quantifying habitat connectivity at multiple scales and assigning conservation priority to habitat patches based on their contribution to connectivity.

Future Representation of Species’ Climatic Niches in Protected Areas: A Case Study With Austrian Endemics

Frontiers in Ecology and Evolution, 2021
Climate driven species’ range shifts may interfere with existing protected area (PA) networks, resulting in a mismatch between places where species are currently protected and places where they can thrive in the future.

Structural and evolutionary features of red algal UV sex chromosomes

Genome Biology
Background Sex chromosomes in red algae have remained relatively understudied, despite their fundamental role in understanding the evolution of sex determination across eukaryotes.

Phenotype–environment mismatch in metapopulations—Implications for the maintenance of maladaptation at the regional scale

Evolutionary Applications, 2019
Maladaptation is widespread in natural populations. However, maladaptation has most often been associated with absolute population decline in local habitats rather than on a spectrum of relative fitness variation that can assist natural populations in ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
