The Occurence of Ecological Traps in Bird Populations: Is our Knowledge Sufficient? A Review
Journal of Landscape Ecology, 2012 Anthropogenic changes in a landscape create new cues for birds, which must permanently adapt to these. If landscape changes occur too quickly, individuals have insufficient time to develop adequate reactions.

Spatial Patterns of Aflatoxin Levels in Relation to Ear-Feeding Insect Damage in Pre-Harvest Corn
Toxins, 2011 Key impediments to increased corn yield and quality in the southeastern US coastal plain region are damage by ear-feeding insects and aflatoxin contamination caused by infection of Aspergillus flavus. Key ear-feeding insects are corn earworm, Helicoverpa

The Effect of Adding Randomly Weighted Edges [PDF]
SIAM Journal on Discrete Mathematics, 2021 We consider the following question. We have a dense regular graph $G$ with degree $αn$, where $α>0$ is a constant. We add $m=o(n^2)$ random edges. The edges of the augmented graph $G(m)$ are given independent edge weights $X(e)$, $e\in E(G(m))$. We estimate the minimum weight of some specified combinatorial structures. We show that in certain cases,

Effect of environmental parameters on squamate reptiles in an urban forest fragment in central Amazonia [PDF]
Acta Amazonica, 2020 The increasing urbanization of the Amazonian biome has promoted the creation of several forest fragments surrounded by an urban matrix, but the relationship of animal assemblages to the urban environment, especially in forest fragments, is poorly known ...

Domination game: Effect of edge contraction and edge subdivision
Discussiones Mathematicae Graph Theory, 2020 Summary: In this paper the behavior of the game domination number \(\gamma_g(G)\) and the Staller start game domination number \(\gamma_g^\prime(G)\) by the contraction of an edge and the subdivision of an edge are investigated. Here we prove that contracting an edge can decrease \(\gamma_g(G)\) and \(\gamma_g^\prime(G)\) by at most two, whereas ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Germ cell tumors (GCTs) often arise in the ovaries and testes (extracranial) but can also develop in the brain (intracranial). We examined the relationship of individual, family, and community‐level socioeconomic status (SES) with stage of disease at diagnosis in a cohort of pediatric patients with GCT from Children's Oncology Group
