Spiking buildings to avoid house martin (Delichon urban) nesting: is it a good choice?

open access: yesJulius-Kühn-Archiv, 2011
We tested the effectiveness of installing spikes (® EcoPic E-5) on building eaves and windows to avoid the nesting of house martins. We found that spikes cannot prevent the nesting or reduce colony size.

Drivers of nest survival in the Tawny-bellied Seedeater Sporophila hypoxantha (Aves: Thraupidae): time-specific factors are more related to success than ecological variables

open access: yesAnais da Academia Brasileira de Ciências, 2021
Tawny-bellied Seedeater (Sporophila hypoxantha) is an endangered (in Brazil) grassland dependent species, whose breeding success remains poorly known hampering conservation measures on its breeding grounds.

Nest and Unnest Operators in Nested Relations

open access: yesData Science Journal, 2008
By distinguishing nested attributes as Decomposable and Non-Decomposable, it is proved that for all nested relations, unnesting and then renesting on the same attribute yields the original relation subject only to the elimination of duplicate data. Therefore, the statement that was popular in nested relations research: "Unnesting and then nesting on ...

NeST graphs

open access: yesDiscrete Applied Mathematics, 2002
Let all graphs \(G= (V,E)\) considered in the paper be simple and undirected ones. \(G\) is a generalization of the known interval graph if there is a set \(\{I_v\mid v\in V\}\) of intervals of the real line and a set \(\{\tau_v\mid v\in V\}\) of positive tolerances such that \(xy\in E\) iff \(|I_x\cap I_y|\geq \min\{\tau_x,\tau_y\}\). Such a graph \(G\

Two decades of community-based conservation yield valuable insights into marine turtle nesting ecology

open access: yesOryx
For the Western Indian Ocean region, there is a significant knowledge gap regarding marine turtle nesting on the continental coast of East Africa. Here we present results from a long-term (2000–2020) community-based monitoring programme in and around ...

Avian Nests and Nest-Building as Signals

open access: yesAvian Biology Research, 2012
Birds may signal their condition, health or parental disposition to mates through large nests or intense or elaborate nest-building. The mass, number or elaborateness of nests may exceed their strict reproductive requirements. In several species, courtship rituals include exhibition of nesting materials to mates, and some nests are not used for ...

Nested LSTMs

open access: yesCoRR, 2018
We propose Nested LSTMs (NLSTM), a novel RNN architecture with multiple levels of memory. Nested LSTMs add depth to LSTMs via nesting as opposed to stacking. The value of a memory cell in an NLSTM is computed by an LSTM cell, which has its own inner memory cell.

Are breeding activities risky for northern bobwhites? An assessment of survival costs of reproduction

open access: yesJournal of Avian Biology, 2023
Behaviors associated with breeding can increase mortality risk. This increased risk can be thought of as a cost of reproduction. Increased movements prior to breeding are common as individuals search for food and breeding sites. These increased movements

Nested satisfiability

open access: yesActa Informatica, 1990
A special case of the satisfiability problem, in which the clauses have a hierarchical structure, is shown to be solvable in linear time, assuming that the clauses have been represented in a convenient way.

TIMING OF SPRING WILD TURKEY HUNTING IN RELATION TO NEST INCUBATION

open access: yesWildlife Society Bulletin, 2015
: State wildlife agencies are often requested to open spring wild turkey (Meleagris gallopavo; hereafter, turkey) hunting seasons earlier to increase hunter satisfaction by hunters hearing more gobbling male turkeys.
